C-C-C-C-CROSSOVER!Ocean Trenches Explained with Professor Alan Jamieson. Join Professor Alan Jamieson, one of our venerated hosts, for a special cross over episode with our friends at Oceanography. This hadal trenches primer episode is a great overview for a first time deep-diver, taking you to the deepest parts of our favorite habitat.
Ocean trenches are Earth’s deepest habitats—and they’re full of life. This episode is a guided dive into the hadal zone (6,000–11,000 meters), where tectonic plates create steep trenches that plunge toward the mantle. Learn what trenches are geologically, what conditions are like at full ocean depth (cold, pressure, darkness), and why the deep sea isn’t a single ecosystem—each trench is its own world. You’ll also get myth-busting on how “the abyss” shows up in pop culture, plus an inside look at the technology that makes trench science possible: multibeam mapping, baited landers, and human-occupied submersibles. Finally, we explore the big research questions scientists are asking about biodiversity, evolution, and connectivity across the deepest ocean.
Special thanks to the Monterey Bay Aquarium for sponsoring this episode.

C-C-C-C-CROSSOVER!What is the Deep-Sea Even Like? With Dr. Thomas LinleyJoin Dr. Thom Linley, one of our venerated hosts, for a special cross over episode with our friends at Oceanography. This deep-sea primer episode is a great overview for a first time deep-diver, taking you to the very heart of our favorite habitat.
What is the deep sea — really? Deep-sea researcher Dr. Thom Linley (Curator of Fishes at Te Papa Tongarewa, National Museum of New Zealand) breaks down the deep ocean as a connected world with distinct zones, ecosystems, and rules — not one mysterious “blob.” From the bathyal and abyssal to the hadal trenches, this conversation maps what’s down there, how life survives crushing pressure and perpetual darkness, and why the deep sea functions as the engine under the hood of the entire planet.
This episode explores:
- What counts as “deep sea” (and why the definition is changing)
- The major deep-sea zones and how they blend into each other
- Whale falls — the deep ocean’s sudden “feast events” and the strange life they power
- Why trenches can be food-rich funnels (and why that matters)
- How deep-sea animals adapt at the molecular level (cells, fats, enzymes)
- The technology that makes deep-sea science possible: landers, traps, cameras, and autonomous systems
- The reality of deep-sea pollution: plastic and “forever chemicals” showing up even at extreme depths
- Why museum collections are time capsules for future ocean science
If you’re into thoughtful mythbusting, weird deep-ocean ecology, and the real logistics of studying a place humans can barely access — you’re in the right place.
Special thanks to the Monterey Bay Aquarium for sponsoring this episode.

In this episode…Welcome back to the Deep-Sea Podcast, your punk take on all things deep sea!
This month Alan has been working on getting a Nova Canton Trough organism menu prepared while Thom has been appearing on and hosting numerous podcast episodes while planning a workshop, fostering kittens and taking a good look at the newest snailfish.
For our interview we are honored to host a three expert superfan session for one of our favorite little devils of the deep- Anglerfish. Join Thom as he chats with James Maclaine Senior fish curator at the Natural History Museum London and our own Andrew Stewart, curator of fishes at Te Papa get together about some of their favorite fishes, the ceratioid anglerfish or deep-sea anglerfish.
Listen-in to back-stage fish curator chat all about the wide variety of Anglerfish shapes and sizes, lures and lights, feeding preferences, reproduction habits, feminist archetypes, game show personalities, and a memorable experience of "pass the football fish". Including Vantablack, pharyngeal teeth, Dreamers, Wonderfish, sideways anuses, love bites, and an epic battle resulting in both combatants being “locked together in death”, this episode will scratch your Anglerfish itch in the most satisfying way.
We also hear from friend of the show Kat Bolstad with her professional opinion on the recently released giant cretaceous octopus paper, and Kat gives a lovely reading from Prema Arasu’s new book of poetry titled Vampire Squid.

This month, we are talking giant testate protists, the coolest things you have probably never heard of. Giant cells on the deep seabed that can reach 20 cm or more. They build elaborate shells, and despite having known about them for hundreds of years, there are still loads we don't understand about them.

Check out our lovely new website where you can find more detailed notes, images and links to the wider reading.
In this episode…Our episode this month is a fascinating collection of interviews from the Cephalopod International Advisory Council Meeting that took place Oct-Nov in Okinawa Japan. Join Kat Bolstad, our roving reporter, as she takes time between bug hunting, seeing her first wild cuttlefish and shaking hands with a new octopus friend to collect interviews with some of the coolest names in Ceph science with a focus on the deep-sea. We hear from 12 Cephalopod experts on a wide variety of topics, including the preferred snacks for cephalopods, the effects of oxygen depletion on egg hatching, water temperature and acidification effects on cephalopod populations, and of course, the correct answer to the viral question: are octopuses actually ALIENS?

The Professor is still down under, organizing conferences and recuperating from Old Mate’s Classic Aussie Sausage Sizzle, a robust event filled with friends of the podcast and still felt 24 hours later.
Thom is freshly back from another big ocean/small boat adventure, in which the ocean always wins and his stomach always loses… everything. He is also stretching his creative muscles and curating an exciting new museum exhibit called Breathe | Mauri Ora at Te Papa, an examination of science into art by Marshmallow Lazer Feast.
Our episode this month is a fascinating collection of interviews from the Cephalopod International Advisory Council Meeting that took place Oct-Nov in Okinawa Japan. Join Kat Bolstad, our roving reporter, as she takes time between bug hunting, seeing her first wild cuttlefish and shaking hands with a new octopus friend to collect interviews with some of the coolest names in Ceph science with a focus on the deep-sea.

In the news, get ready for updates on:
- Deep diving manta rays using the ocean bottom to navigate
- A newly launched AI tool to map the Deep- Sea
- Bright blue mud filled with fat molecules indicating life in the deep
- Corals and Crinoids sharing symbionts and cycling nitrogen
- And an update from the Unseen Ocean Collective about the work they are creating for a show in Juneau Alaska in 2026.
On the Discord, we’ve been busy with:
- Voting on the Holiday Party movie
- Started a long overdue ART channel, and a new Pets channel
- Photo tours of submersibles and Okinawa
- Early Holiday celebrations by one of our hosts
- Great feedback and conversation on our last episode.

Welcome to the PRESSURISED version of episode 63, just the science, none of the wafflePRESSURISED: Bioluminescent Symbiosis with Margaret McFall-Ngai | The Deep-Sea Podcast | Episode 63
Our guest this month is Dr. Margaret McFall-Ngai, an animal physiologist and biochemist who is a staff researcher at Carnegie Institution for Science’s Division of Biosphere Sciences and Engineering, with her lab stationed at the California Institute of Technology in Biology and Biological Engineering. Dr. McFal-Ngai talks us through her work on the stable beneficial relationship between the Hawaiian bobtail squid (Euprymna scolopes) and its partner, the luminous bacterium Vibrio fischeri. Although technically not a deep-sea species, this relationship and its details might help us understand how deep-sea life creates bioluminescence and the possible life cycle impacts for the creatures involved.

Episode SummaryIn our newest episode, Bioluminescent Symbiosis, we speak with Dr. Margaret McFall-Ngai, an animal physiologist and biochemist about her work with the Hawaiian bobtail squid (Euprymna scolopes) and its partner, the luminous bacterium Vibrio fischeri. McFall-Ngai provides a great synopsis of how this stable beneficial relationship not only creates light, and supports the bobtail maturation, but can also help us understand what could be going on in the light organs of deep-sea animals.

In this episode…Welcome back to the Deep-Sea Podcast, your punk take on all things deep sea!
The Professor is jetsetting as always, back in Edinburgh after a stint getting all the equipment ready in the Canary Island and is now happily being confused with professional racecar drivers. He will be back in Perth shortly to celebrate the Deep-Sea center paper publishing streak and reconnect with his Capybara spirit animal.
Thom is being called out in New Zealand Parliament, for all the right reasons, and he spent some Deep-Sea conference time in China, avoiding typhoons and pondering science ideas.
We are also celebrating 300,000 podcast downloads of the podcast, and appreciate our fans immensely!

Here’s our fourth episode of The Deco-Stop; a deeper look into the humans behind deep-sea science and technology. We’ve done our science dive, and now it’s time to decompress, and discuss tales at sea, career paths and the social & political aspects of deep-sea science. We have gazed into the abyss, and now it's gazing back at us.
Alan and Thom speak with Yakup Niyazi, a marine geoscientist who first saw the ocean at the age of 27. This fourth instalment in the Deco-Stop series, which focuses on the human element of deep-sea research, is an inspiring episode about one man’s journey from the desert to the bottom of the ocean, his challenges, achievements, and the deep community support he received along the way.
Check out our lovely new website, where you can find more detailed notes, images and links to the wider reading.
In this episode…Welcome back to the Deep-Sea Podcast, this month we have a heartwarming Deco Stop episode and are again exploring …‘the human element in deep sea stories..’ - Alan
In our fourth instalment of the Deco-Stop series, Alan and Thom speak with Yakup Niyazi about his journey from the edge of the Asian Desert to the bottom of the ocean. An ethnic Uyghur who grew up in the city of Aksu, at the edge of the Taklamakan Desert in Central Asia, Yakup grew up not only physically but also emotionally and culturally removed from the sea. Yakup's early experiences pose some interesting questions: What is it like to grow up in a culture that doesn’t really have a concept of the ocean, and few descriptive words for the ocean? How do you interact with the ocean if your only experiences are from movies and television?
His incredible story is filled with overcoming adversity, fulfilled dreams, landscapes (and seascapes) that come full circle, and a deeper appreciation of the ocean than most people will ever experience. Despite humble beginnings, Yakup has an impressive roster of achievements and a social circle of supportive connections who only want to see him succeed further.
This inspiring episode reminds us that, regardless of our original circumstances, the world is a vast place filled with incredible opportunities. One day, you might find yourself exiting a hadal submarine, surrounded by the heartwarming cheers of friends and colleagues, having successfully visited the bottom of the ocean you only saw for the first time at age 27.
“I was a camel before, from the desert, but now I am a shark swimming in the ocean”- Yakup Niyazi

In a follow-up to one of our favourite episodes, Ep 10 Here be Monsters, we bring Tyler Greenfield back for another fascinating chat, this time about Mythbusting in the age of Artificial Intelligence. Our feeds have been filled with images of mermaids, bizarre creatures supposedly from the depths and even strange barnacle washing videos, so we ask Tyler to bring his expertise to weigh in on the prevalence and problems with AI images.
Guest InterviewTyler Greenfield is a paleontologist and cryptozoologist whose blog, Incertae Sedis reveals the truth behind some cryptozoological stories and paleontological mistakes. Since his appearance on episode 10, Tyler has finished his bachelor’s, written a good few papers, appeared on other podcasts (none as good as his debut of course) and is almost done with his masters and is about to start his PhD. He was even a credited consultant on the new (2025) Walking with Dinosaurs.

Welcome to the PRESSURISED version of episode 61, just the science, none of the wafflePRESSURISED: Trench nutrient cycling with Ronnie N. Glud | The Deep Sea Podcast | Episode 61
Guest Interview: Nutrient cycling in the hadal trenches (6 to 11 km) and the crucial role they play in global element cycling. Professor Ronnie N. Glud, a leading biochemist and Director of the Danish Centre for Hadal Research (HADAL) talks us through how the trenches, once thought to be barren, are actually "dynamic deep-sea hotspots with intensified microbial activity and diversity". Learn about:
- How hadal trenches act as "depocenters" for organic material, leading to microbial activity that's 2 to 6 times higher than in adjacent abyssal sites.
- The surprising diversity of microbial "generalists" that easily adapt to the immense pressure and low temperatures, aided by viruses that facilitate "horizontal gene transfer".
- The return of full anaerobic diagenetic processes (like sulphate reduction and anammox) in trench sediments, making them significant sinks for fixed nitrogen.
- The role of marine snow and seismic activity in efficiently transporting organic matter and, surprisingly, pollutants like PCBs and heavy metals to these remote depths.
- Why these trenches are not isolated environments but are highly connected to surface ocean processes, even responding to climate-driven changes in primary production.

In this episode…Welcome back to the Deep-Sea Podcast, your punk take on all things deep sea! Join Dr. Thom Linley and Professor Alan Jamieson as they dive into the latest from the abyssal plain and beyond.
Deep Sea News Highlights: We kick things off with a rethinking of the deep-sea boundary! Professor Alan Jamieson discusses his recent "food for thought" paper that challenges the long-held 200-meter definition, arguing for a more scientifically relevant boundary of 1,000 meters. Find out why this seemingly arbitrary line might be doing "a lot of damage" to our understanding and attitude towards the deep sea.
Also in the news, get ready for updates on:
- A new story map on mesophotic reefs following the Deepwater Horizon spill in the Gulf of Mexico.
- An exciting project charting shipwrecks in the Great Lakes using cutting-edge ROV technology for 3D modelling.
- The discovery of a deep-sea limpet named after a One Piece character, found at an astonishing 6 kilometres deep!
- How Earth's deep-sea microbes are being used to model potential life on Jupiter's moon Europa.
- Groundbreaking research on a new bioplastic that vanishes by over 80% in extreme deep-sea conditions, offering hope for sustainable solutions.

In this month's episode, we discuss mesophotic reefs, the deeper extents of coral reefs that have been overlooked in the past. It’s a wild ride that leads us to homemade hyperbaric chambers, the aquarium trade and the world’s most expensive fish. Strap in for a rollercoaster ride as we dive to the limits of scuba.

eDNA with Georgia Nester | The Deep Sea Podcast | Episode 59
Welcome to the PRESSURISED version of episode 59, just the science, none of the waffleFor this month’s interview, we speak with Dr. Georgia Nester, a colleague of Alan’s from the University of Western Australia, about eDNA (Environmental DNA is any genetic material left behind by organisms in an environment). She talks about how several collection methods, eg.: Niskin bottles, sponges and paper filters, located on the deep-sea lander system, can retrieve different types of eDNA from the deep. Georgia also touches on how diel migrators can really mess with eDNA data, and larvae gave her a surprise when she kept getting hits from very deep-living fish in her surface samples. Georgia even used a water sample to locate surprise eDNA evidence of the Giant Squid in Australian waters, which Al takes as a chance to remind Thom of his Antarctic colossal squid failure.
Alan talks about how valuable he thinks eDNA is, how it can give a great snapshot of what can’t be seen on the footage or in the submersible, and how it might be able to narrow down species that are difficult to catch, like Bassozetus cusk eels.

eDNA with Georgia Nester | The Deep Sea Podcast | Episode 59
“Exploration is about the place, adventurism is about the person, science is about the question”
Professor Alan Jamieson
In an episode recorded earlier than usual, which is to say not recorded late, and so perhaps recorded right on time?... we are talking about environmental DNA or eDNA.
Thom is headed off to Norfolk Island, north of New Zealand, to characterize the unique life in the region and hopefully not be eaten by sharks. Alan’s been up to secret things, organizing everyone’s lives and, for a change, is recording this episode from the same country as the last one.
In the news, Thom and Alan discuss a recent paper about the extent of ocean exploration, the valuable research it was based on, and the unfortunately defeatist tone. There is a lot left to do, but we have done so much!
Also in the news: Bottom trawling releases not only organic carbon into the ocean but also pyrite, which reacts with oxygen in the water and reduces the oceans’ ability to absorb carbon from the air. An art installation pairs a Sri Lankan artist with JAMSTEC and NuStar Technologies for a collection of steel cubes located 7,000 meters (23,000 feet) below the ocean close to the Marianas Trench. The cubes are housed in a seismic monitoring system designed for registering tectonic plate movements. And finally Al and Thom discuss gene mutation in deep-sea fish and a new paper that gives evidence to an old theory that some deep-sea fish are “ancient survivors,” from dinosaur times, while others are “new immigrants,” post mass extinction.
For this month’s interview, we speak with Dr. Georgia Nester, a colleague of Alan’s from the University of Western Australia, about eDNA (Environmental DNA is any genetic material left behind by organisms in an environment). She talks about how several collection methods, eg.: Niskin bottles, sponges and paper filters, located on the deep-sea lander system, can retrieve different types of eDNA from the deep. Georgia also touches on how diel migrators can really mess with eDNA data, and larvae gave her a surprise when she kept getting hits from very deep-living fish in her surface samples. Georgia even used a water sample to locate surprise eDNA evidence of the Giant Squid in Australian waters, which Al takes as a chance to remind Thom of his Antarctic colossal squid failure.
Alan talks about how valuable he thinks eDNA is, how it can give a great snapshot of what can’t be seen on the footage or in the submersible, and how it might be able to narrow down species that are difficult to catch, like Bassozetus cusk eels.

Song of the month: Crazy Train by Ozzy Osbourne, performed by William Jamieson
Welcome to the PRESSURISED version of episode 58, just the science, none of the waffleWe are still talking about Antarctica, the continent that keeps on giving!
For this month's interview, we speak with Devin Harrison - Marine Geoscientist/Postdoctoral Researcher at Kelpie Geoscience - Devin is a postdoctoral research fellow at Kelpie Geoscience. His research utilises high-resolution topographic models of the seafloor and complementary geophysical and geospatial datasets to understand the geomorphic evolution and process landform relationship of the deep sea and the continental shelves. Devin is particularly interested in the glacial geomorphological record and the evolution of glacial environments from the last glacial maximum (~20-25 thousand years ago) to the present day.

We are still talking about Antarctica, the continent that keeps on giving!
Alan and Thom discuss trying to stop working momentarily, constructing a treehouse, and acquiring a shark.
In the news, we rattle off a list of newly discovered species with some very cool (but hard to pronounce) names. There has been a lot of squiddy news. Footage of divers swimming with a giant squid has resurfaced; in an exclusive for the podcast, Alan has recorded more amazing Magnapinna (bigfin or elbow squid) footage. And the biggest bit of news: the colossal squid has been seen alive in its natural habitat for the first time! Thom and Kat were part of the press conference.
Megalodon (the not-deep-sea and very extinct shark) has been reassessed based on what we do know. It was likely longer and slimmer than we thought, and we have estimations for their speed and size at birth.
We also have a new coelacanth population and a classic car found in the deep.

Song of the month: The Midnight Zone by SLADE
It’s the last in our run of episodes about Antarctica. We are all back home, and we promise to stop bothering the poor continent.
Thom couldn’t talk about it until after the press release, but the Schmidt Ocean Institute cruise he was on had to look at the seabed under a 150-meter-thick ice shelf right as it moved out of the way. We talked to the science leads on that cruise, Patricia Esquete and Sasha Montelli. We learned about the hydrography and glaciology of that region and then the seabed and communities that were revealed when the ice shelf moved away.

It’s the last in our run of episodes about Antarctica. We are all back home, and we promise to stop bothering the poor continent.
Alan and Thom discuss returning to an inbox of horrors and readjusting to time away.
More cable cutting in our news updates, blobfish being voted fish of the year, and the tongue-eating louse potentially being invertebrate of the year. We don’t want to say we influence the news, but it seems a little spooky.
Thom couldn’t talk about it until after the press release, but the Schmidt Ocean Institute cruise he was on had to look at the seabed under a 150-meter-thick ice shelf right as it moved out of the way. We talked to the science leads on that cruise, Patricia Esquete and Sasha Montelli. We learned about the hydrography and glaciology of that region and then the seabed and communities that were revealed when the ice shelf moved away.
Kat and Thom updated us on what it was like to join a tourist expedition ship, and we grabbed a Coffee With Andrew to learn what it was like to dive almost 5km deep in a sub.

Happy birthday: The guests aboard the Ocean Endeavour
Coming to you from an Airbnb, above a ski hire shop, next to a construction site in Ushuia, Argentina… It’s a very special episode as we continue to pester Antarctica.
Alan checks in from Barcelona for mysterious reasons. We’ll have to get the truth our of him in the future…
Lots is going on in the news; deep-sea fish keep turning up, including a little Melanocetus anglerfish - sometimes called a black seadevil. This has had a real impact on people. The media tried to call it a monster, but the people fell for this little fish. An orfish, the doomsday fish, also turns up, but is that really a sign of doom?
There’s a new giant isopod, and it’s named after Darth Vader - Bathy-normouse! We get excited about Beryllium-10 and ponder neutrinos.
But what we are here for today is a very special birthday. Our favorite and most elusive colossal squid, Mesonychoteuthis hamiltoni, has been described for 100 years but never seen in its natural environment! We are having a birthday bash for the big girl.
Joined by Kat Bolstad of the Auckland University of Technology, Squid Squad, we learn what we do and don’t know, as well as the project Thom and Kat came up with to try to find it.

Now it’s Thom’s turn to hit Antarctica. He’s out with the Schmidt Ocean Institute on the Antarctic Climate Connections expedition to the Bellinghousen Sea, to the west of the Antarctic Peninsula.
He will record, edit and upload a podcast from there… somehow. This episode may sound a little rougher as a result, but the content is gold as ever… Underrated belter alert.
We talk to Antarctic fishes expert Thomas Desvignes about the fishes that are only found there and their amazing adaptations. Of course, we also have a remote coffee with Andrew.
We’re really trying to make this project self-sustaining so we have started looking for ways to support the podcast. Here’s a link to our page on how to support us, from the free options to becoming a patron of the show. We want to say a huge thank you to those patrons who have already pledged to support us:

The Prof managed to have some downtime with the family in Antarctica and has some great stories to tell, he’s a chopper guy now. He’s over subs and only into helicopters now… the subs of the sky.

It’s a big one! With The Professor down in Antarctica and Dr Thom not too far behind him, we’ve got an update live from the field. We’re talking about Antarctic submarine dives, below-freezing trenches, unexpected uses of glacial ice and, of course, the importance of growing a beard…
But they’re not alone! This month we’re joined by the incredible Shaylyn Potter (Marine Scientist, Sub Pilot and polar diver) as she talks us through the intricacies and unique nature of this environment. We learn about what makes an iceberg different from a bergy bit (yes, that’s a real word), and why plans don’t always go as planned in the south.

With Dr Thom and The Professor busy prepping for their upcoming expeditions offshore, we had time to squeeze out one more episode before they set sail.
We caught up with the legendary Di Tracey from NIWA to talk all things deep-water corals. How they live, what makes them different from their shallow water relatives, and how they are adapted to life in the deep dark ocean. Di's long career in deep-sea ecology is also intertwined with her extensive work in making the marine sciences a better place for women to work. She talks us through what it was like to begin her career offshore, often being the only woman on board, and how she helped change the industry for the better.

In the news this week we have a few exciting new updates. We can indeed confirm that as of our last episode where we spoke about the vulnerability of subsea cables, there were multiple apparent attacks and cables were cut. We can only assume that hostile nations do indeed listen to the deep-sea podcast (thanks for subscribing!).
Andrew is back from his stint offshore and he is chock-full of stories for us. Brand new dragonfish species, near-misses with box jellyfish and also some cookie-cutter sharks. It's all happening!

This month, we come face to face with deep sea species in our blackwater diving special.Join us this episode as we jump into the fascinating world of blackwater diving, where expert scuba divers plunge into the open ocean at night in order to catch a glimpse of our favourite deep sea faces. We talk with expert blackwater divers to find out what it’s like to venture into the open ocean at night, when deep sea species rise from the depths to feed. How do they capture such remarkable photographs in such challenging conditions? What are some of their favourite species to encounter? What is it like to see bioluminescence in person and how is this related to science and the discovery of new species? Whether you’re a pro-diver yourself or prefer to stay dry, this episode is jam-packed with interesting stories and insights into this poorly understood environment.

With the professor momentarily pinned down in Perth, we thought it would be the ideal moment for him to talk to us all about his local waters, the great Australian deep sea.Did you know that 70% of Australian waters are deeper than 1000m? Now that’s a lot of deep sea! We hear from the Minderoo-UWA Deep Sea Research Centre’s deputy director, Dr Todd Bond about the huge array of marine geographical features and biodiversity in Australia’s waters.

We also check in with our resident squid expert - Dr Kat Bolstad after the highly anticipated Squidtember comes to a close. Did you vote for your favourite squid, and if so, how did they score? We reckon Alan’s recent videos from the Tonga Trench (that he teased last episode) might’ve had a subtle influence…

We made it to episode 50 and managed to pin down the professor to tell us all about his adventures offshore in the world’s second deepest point: the Tonga trench.Expect to hear all about how the colossal deep-sea expedition is going, including the time Alan piloted a submarine to 2000m, stumbled upon a rarely seen deep-sea squid, and made poor Steve’s life difficult (the onboard media guy). Life on land is also just as chaotic as Alan has been jetsetting all over the world, with his shiny new OBE medal safely tucked in his backpack pocket, plus a very mysterious scroll from the king arrived and is now living proudly in his downstairs loo.
For those who really love the show, Alan shared with us pictures of all the species he found in the Tonga trench, and this extended video version of the episode is available now via our Patreon (and will be made publicly available on September 20th).

As it turns out, returning to life on land after a mega deep-sea expedition takes a lot of work! So, whilst we aren't quite ready to share with you our Tonga Trench special, here is a mini-episode to keep you busy until we get back to you with episode 50.
We're talking all about SQUIDTEMBER with long-time friend of the show, Kat Bolstad from the AUT Squid Squad. Which squid will reign supreme come the end of the month? It's up to you to decide! You can find the links to vote, plus all of the other festivities here on the AUT Twitter page.
Thom and Kat also tell us a little about their latest project... attempting to flirt with deep-sea squid. Light-up paddles are involved.
Thanks so much for bearing with us whilst we get episode 50 together for you, we can't wait for you to hear it soon!

To finish off our cartilaginous fish mini-series, we’re getting into our personal favourite: the chimera.These little oddballs are closely related to sharks and rays but often go unmentioned. They are full of intriguing quirks, from lacking a stomach to possessing a reproductive appendage on their head! We speak with Dr Brit Finucci from NIWA, a lover of deep water sharks and champion kicker of heads (she is also a competitive Muay Thai fighter) all about these fascinating fishes and why they are so interesting.

We also speak with Leo Richards from Natural World Facts about his journey into making deep sea documentaries. If you have ever searched for deep-sea videos online, then you will have definitely come across Leo’s content, as his captivating way of sharing the deep-sea has reached millions of people.
Talking about high-quality content, The Professor has been joined offshore by a team of filmmakers, ready to capture the latest in hadal research. So expect some highly professional footage to come out in the next few weeks!
Finally, Andrew talks us through some physical features of the Chimera, including its pretty hefty defensive spine and some gnarly stories about things getting impaled.

The Professor is trapped in paradise (somewhere in Fiji) whilst he quarantines before his next big offshore expedition. But he’s not alone - alongside his new pal Roger (the guard gecko) he's quarantining with deep-sea celebrity, Jason 'J-Rod' Rodriguez. The famed SuBastian ROV pilot is joining Alan on this next leg of the expedition to the Tonga Trench. Make sure you're following us to hear all of the updates in our next episode!
Andrew is back from his travels and was just as excited about our Lake Baikal episode as us! In this month's Coffee with Andrew segment, he talks us through the unbelievable similarities between deep-ocean and the deep-lake fish of Baikal.

Can we safely bring deep-sea organisms to the surface and keep them alive? Certain species, such as the giant isopods and giant Japanese spider crabs have been kept in aquaria in the past but the number of animals we can maintain long-term is quite small. The Monterey Bay Aquarium’s new Into the Deep exhibition has succeeded in keeping animals never before put on public display, some are even new to science. Not only that, but they have even had some success in getting them to reproduce! Figuring out what conditions these animals need and observing them over long periods will allow us to learn huge amounts about animals we usually only get a glimpse of. We talk with aquarists Ellen Umeda and Michelle Kaiser and life-support engineer Brian Maurer about the years of work that went into keeping these animals and giving the public a very personal deep-sea experience.

Located in southern Siberia and covered in thick ice for almost half of the year, the colossal Lake Baikal reaches depths of 1600m making it the oldest, and deepest lake in the world. With hydrothermal vents, methane seeps and vast swathes of endemic species, this ancient lake was too tempting not to talk about.
We speak with Professor Marianne Moore, a Limnologist who has been working on the lake for over 2 decades. She guides us through its incredible ecosystems and species such as the world's only freshwater seal, deep water insects and foot-long flatworms!

She guides us through its incredible ecosystems and species such as the world's only freshwater seal, deep water insects and foot-long flatworms! Plus, we hear about the myths and mysteries of the lake: from scientifically testing whether the mafia can use amphipods to effectively dispose of bodies, to whether there really is 1600 tonnes of gold hiding at the bottom of the lake.
The Professor is back on land after a succession of crazy adventures which includes writing a paper on backwards swimming in deep sea fish, finding the worlds deepest nudibranch (possibly) plus discovering his friends live in the most metal place ever.
There’s no Coffee with Andrew segment this month as he is taking a well deserved break (and is possibly touring the country looking for the strangest milks he can find), but we do hear from Kakani Kajita about the recent release of FathomVerse - the mobile game helping to contribute to deep sea citizen science.

One of the most exciting parts of our job is going to places that no one has ever been before and seeing things that no one has ever seen. It turns out, we were making that far harder than it needs to be, we can do all this from home! Several of the big names in deep-sea exploration live-stream (or dive-stream if we’re being cute). With just a few seconds delay, you can see deep-sea exploration as it happens and may be present for very significant finds. You never know what you’re going to find down there.
The big players in this space are the Schmidt Ocean Institute, Nautilus Live from the Ocean Exploration Trust and Ocean Exploration/Okeanos Explorer from NOAA. We are lucky enough to chat with Kasey Cantwell, the Operations Chief of the NOAA Ocean Exploration Expeditions and Exploration Division. We talk about the amazing opportunities this new way of doing science presents. From allowing 300 experts to take part, to swapping out your expert team when you find something unexpected and even the physical and societal barriers that can be removed. But it’s not just about getting science done, it’s about sharing these experiences with everyone. Online communities are forming around these streams and illustrations, poetry and memes are just as valid outputs.
Check out our podcast merch! Please do send in any pics of you wearing the merch. We find the idea of real people in the actual world wearing this so surreal!

This month we're talking about the flattest of the elasmobranchs: the bottom-dwelling batoids - the deep sea rays and skates!
We’re kicking off our cartilaginous fishes (Chondrichthyes) mini-series with the batoids - the rays and skates! Sharks are often associated with the deep sea, but did you know that batoids have been observed as deep as 3000m?
We speak with Will White who researches elasmobranchs across the world and who has described 50 species! He talks us through the differences between sharks rays and skates, and how these species utilise the deep sea. We hear about their fascinating (and hugely varied) reproductive strategies like those that are viviparous (will keep the eggs in their uterus) and others that are oviparous (will lay the eggs).

We have often talked about how difficult it is the get data from the deep sea… but would you believe that the bottleneck to our understanding of the deep ocean, at least as far as visual data, is processing those images? Turning a picture of the deep sea into a list of species, habitat type, sediment type etc. is a time-consuming process that requires a wide range of skilled people.
Due to time/funding constrains a lot of valuable information is lost. A team looking at a specific question will have lots of information in their data that other teams could use.
A picture is worth a thousand data points.
We chat with Dr Kakani Katija, the co-founder of FathomNet, an open-source repository for labelled deep-sea imaging data. The platform is still in beta but it is hoped that it will allow scientists to easily and usefully share their amassed data in a single and easily searchable place.
But what about that processing bottleneck? The tech-savvy listener may have noticed that a massive collection of labelled image data is exactly the sort of thing you need to train a Machine Learning or Deep Learning algorithm. Can we automate a lot of the time-consuming image processing and let the experts focus on the new and unusual stuff? It’s at this cutting edge that things get exciting and we may be at the cusp of a marine science renaissance.
We also launch our podcast merch! Please do send in any pics of you wearing the merch. We find the idea of real people in the actual world wearing this so surreal!

https://www.armatusoceanic.com/podcast/045-hagfish
What has no jaw, inverted horizontal teeth, saggy skin and can produce litres of suffocating slime when touched? it’s the episode you’ve been waiting for… The hagfish special is here.
Dr Thom is back from his stint offshore, and The Professor pretty much now lives in a submarine, but that hasn’t stopped them from finally reuniting to make this special episode all about hagfish. We’ve talked about them a lot on the show, and decided it’s time to pass them the mic. So expect lots of slimy stories, toothy tales and a whole load of hagfish trivia you never knew you needed.
There’s lots of updates after so many recent deep sea expeditions, with Thom’s latest cruise discovering many new species and Alan sharing live updates from the sub. Keep up with their latest goings-on via twitter!
We speak to the king of the hagfish, Professor Doug Fudge, who has been studying these critters and their (in)famous slime for decades. We ask all the interesting questions like: how do they make so much slime, do they have any predators and why do they look like that?

It’s February, the month of love and there’s love in the deep ocean too. We talk reproductive strategies in the deep sea with Professor Craig Young, Dr Autun Purser and Dr Mike Vecchione. How do you find a mate in the sparsely populated deep ocean? How can egg and sperm meet when you are fixed growing on a rock? How can your babies disperse and find a suitable habitat, especially if you live in a rare habitat like a hydrothermal vent? We find the solutions to all these problems and more.

It finally happened… we brought you an episode which was recorded almost completely offshore. With Dr Thom in the Bounty Trough and the Professor somewhere in the Pacific, this episode is quite the wild card. Whilst Thom has been busy crocheting fishing nets (that’s science folks), Alan was left to take the reins and he decided to go a little off-piste. We bring it back to the good old days with one of Alan’s (in)famous rants. This one is titled: When does the sea become the deep sea, and why it needs to be changed. Expect to hear about the history of why we decided what makes the deep-sea ‘deep’, and why it might not make sense anymore in our modern world. We’d love to hear your thoughts on this and whether you agree with Alan.
Finally, we check in with a key individual in the online deep-sea community space: Jeff Day. Jeff’s been on our radar for years with his immense knowledge of deep-sea cephalopods and we thought we’d finally hand him the mic. He talks to us all about his love of deep sea creatures and how he contributes to the field in unconventional ways.

Are you looking for a podcast episode that contains the return of the blobfish, golden crochet hooks and rare deep-sea squid? Well, look no further than this episode of The Deep-Sea Podcast!
It finally happened… we brought you an episode which was recorded almost completely offshore. With Dr Thom in the Bounty Trough and the Professor somewhere in the Pacific, this episode is quite the wild card.

Expect to hear about the history of why we decided what makes the deep-sea ‘deep’, and why it might not make sense anymore in our modern world. We’d love to hear your thoughts on this and whether you agree with Alan.
Dr Thom does make an appearance in this episode, giving us a run-down of how the research cruise is going (SPOILER: The blobfish is back). Plus, we hear about the original blobfish and how exactly it came to be an internet sensation, from the man who was there: new fan favourite, Andrew Stewart.
Finally, we check in with a key individual in the online deep-sea community space: Jeff Day. Jeff’s been on our radar for years with his immense knowledge of deep-sea cephalopods and we thought we’d finally hand him the mic.

As promised in the Christmas special, we call the ‘squid-phone’ – a special line used by scientists globally when they seem something strange and squiddy. On the other end of that line is Mike Vecchione, the expert on cephalopods. We talk giant and colossal squid (to audible groans from Mike); the bigfin squid (Magnapinna), most famous for being the squid with the long trailing arms that’s often used as an example of terrifying deep-sea creatures, but also a species, genus and Family that Mike described and would love more sightings of.

In deep sea news: Norway has decided to go ahead with deep sea mining, cold coral reefs are being discovered, and hoards of marine fungi have been found in the twilight zone! But more importantly than all of that: the Professor was awarded an OBE! His sword and noble steed are currently in the post (first class), and we’re hoping they reach him in Perth from the Palace.
We’ve also started a new segment with long-time friend of the show, Andrew Stewart who has an interesting hobby of manufacturing cod-liver shark-liver oil. Expect more unexpected stories from Andrew in future episodes!
Finally, we want to say thanks again for your support! We have lots of exciting upcoming episodes all about the (in)famous hagfish, deep sea sharks and our favourite: chimera. Stay tuned!

We think of the deep sea as an eerily quiet and spooky place but that isn’t completely true, animal communication, seismic activity, human noise and even the sound of rain and waves from 10 km above. We chat with undersea audio expert Dr David Barclay about the fascinating audio properties of the deep ocean. As we are talking audio data on an audio medium, lets have some fun with a game of ‘what can we grenad-hear’ where Thom tries to guess the deep-sea sound.

THE DECO-STOP: A DEEPER LOOK INTO THE HUMANS BEHIND DEEP SEA SCIENCE AND TECHNOLOGY.
This is our third Deco-Stop episode, and this time we’re focusing on eco-anxiety. We are currently in the midst of an ecological crisis, but eco-anxiety is something of a mental health crisis in response. Many of us who work in this space (and many of us who don’t) are feeling these emotions, including plenty of our listeners who have got in touch to share their experiences. As such, we’ve wanted to make this episode for some time, but during it’s production, it became a far bigger subject than we were ready for. One thing that did become apparent, is that this is a dangerous subject and it is something that can do real harm. In this episode, we share with you some stories of how different individuals have influenced their lives in a direct response to eco-anxiety. Plus, we hear from the perspective of a psychotherapist who specialises in the field of climate & eco-crisis psychology. However, this is not a list of answers, and the priority is your health and safety and as the listener.
We hope that this episode offers an insight towards such a big and difficult topic. Whilst it won’t leave you with a complete set of instructions on how to fix the world, we hope you find it comforting that there is a huge number of people who are feeling the same as you are. It’s a lrngthy one, so grab a cup of tea, give your local tree a quick hug, and tune in to this beefy episode of the Deco-Stop.

We love going to sea, it is probably the best part of the job. That’s where most of our adventures happen, that’s where most of the exciting discoveries and firsts happen and it’s where we meet some of the most interesting people. We want you to have a great time at sea too and not be put off by a bad first experience. Poor packing or a faux pas could spoil the whole experience and we don’t want that. We put together some advice for your first trip. Forgive us if parts seem patronising, they are all things we have seen spoil someone’s trip and with everything else to worry about, it’s easy to forget the simple stuff.
We chat with Larkin, a deck-hand turned youtuber about life at sea and sharing that experience through her videos. What is her average day like at sea and how’s the morning commute when your office is a small response vessel chasing a submarine 10,000 m below you? How can you get a celebratory tattoo offshore from an unqualified scientist? “Don’t worry, he’s a doctor, not that sort of doctor but don’t worry about that!”

"Exploration is curiosity acted upon." — Don Walsh
In this month’s episode, we’re honouring the late great Don Walsh, who sadly left us this month. You may have noticed that we hadn’t heard from Don in a good few months. He had a couple of ops that required some getting over, but that wasn’t going to slow him down. In September he was going through the Northwest Passage, a trip he had attempted 2 previous times but had been scuppered by weather and vessel trouble. Don’s unwavering commitment to deep-sea exploration meant that the monthly sea stories were no longer possible but we weren’t going to let the legendary Don Walsh sneak off without some fanfare, not after everything he’s done for us.
We were putting together a Christmas episode where we could share some drinks and stories with Don and give him a proper send-off. While we were sorting out dates that everyone could do, Don passed. 92, nodding off in his favourite chair at the remote home he loved, surrounded by nature.
Over the last 3 years it’s been a privilege to have Don recount one of his endless list of stories with us every month, stories that always made us smile. In some attempt to raise a toast to him and all that he’s done for the community, we bring you this Don Special episode. He will be missed.
Legend.

https://www.armatusoceanic.com/podcast/016-biodiscovery
We are in desperate need for new bioactive compounds. Super bugs are on the rise as evolution finds a way of thwarting our antibiotics. We are also continually on the hunt for compounds that can fight disease, ease suffering or get your teeth super white. The natural world has been experimenting for millions of years and has come up with solutions far more elegant than we could come up with.
The ocean, and in particular the deep ocean, may be the best place to look for new compounds but is this a threat to the ocean? It is often mentioned alongside seabed trawling, climate change and mining as a threat to the deep ocean. Should we call it bioprospecting or biodiscovery and what’s the difference? If most of the world’s ocean belongs to everyone, who owns a discovery? How do we ensure that developed nations, who are better equipped to benefit from a discovery, don’t leave developing nations out? Are companies really patenting naturally occurring compounds? If we find something exciting, what is the process for it becoming the next wonder drug?
While they both agree that looking for new compounds in the deep sea sounds good, Alan and Thom are soon stumped by the complexities of actually making that happen in a fair and sustainable way. Luckily, they can call on Professor Marcel Jaspars, head of the Marine Biodiscovery Centre to help us through the practicalities of biodiscovery but also its political and ethical complexities.

We all know that Thom and Alan aren’t the biggest fans of ‘air-breathers’ aka. marine mammals like dolphins and whales, but there are a few species that are allowed into the deep-sea club. We hear from Dr Nicola Quick who researches the incredibly elusive beaked whales, a group that likely spends the majority of their time in the deep sea. These interesting whales have been seen diving to depths of 3000 m, which way exceeds the max depth of their more famous cousin, the sperm whale (who usually hang out at around 1500m deep).

We are still exploring the parallels between space and deep-ocean exploration. It feels like technology and access is really accelerating in both spheres. Don calls in to teach us about the amount of water in our solar system and the potential new job title – Planetary Oceanographer.
When samples or access to a vehicle is limited, how can we ensure that resources are shared fairly? We have seen it lead to disagreements on ships. With something as singular and precious as a Mars rover, how are its objectives planned? Evan Hilgemann, mechanical engineer and Curiosity Rover driver with NASA’s Jet Propulsion Lab (JLP) joins us to share how a rover is managed. We chat about the parallels between exploring mars and exploring the deep sea, the similar issues we face, what we can learn from each other and most excitingly, where is technology heading on both fronts! These are exciting times.

Plus, we get to hear the infamous story of when The Professor and Teresa docked in Lisbon during a cruise and Teresa was able to clear out a bar for the whole of the crew.
Plus, the deep sea has been all over the news this month with lots of new papers being released. Magnetic bacteria have been found by the (phenomenally named) HYPER-DOLHPIN ROV, mysterious markings on the seafloor turn out to be face-planting fish, and scientists have been training jellyfish to navigate through assault courses (kinda).
The Professor’s deep sea research lab have also been busy recently with lots of exciting videos coming out from their landers. Plus, one mystery creature has the whole team stumped. Is it a nudibranch? Or is it something else entirely?

The topic for this double episode is, as ever, the deep sea. But this time we are talking about the deep sea… Innnnnn Spaaaaaaaace! It turns out there is deep sea outside of earth in our solar system in the ice-covered moons of the gas giants. How likely are they to contain deep-sea life completely independent from the life that originated on earth? Thom chats with astrobiologist Kevin Peter Hand, author of Alien Oceans: The search for life in the depths of space, and director of NASA’s Ocean Worlds Lab. What are the best candidates for alien life in our solar system? What could that life be like and why does our own deep ocean provide a perfect test bed?
It turns out that the early versions of the vehicles which may some day explore these ocean worlds are already in development. Thom chats with Casey Machado, Research Engineer at Woods Hole Oceanographic Institution about the Orpheus AUV, the first generation of such vehicle and a new asset to the exploration of our own deep ocean.

We might be a little late this month but we’ve packed in as much as we can with this one. We’re covering all the latest deep sea news, including new deep sea habitats, octopus gardens and brand new amphipod species. Plus, we hear from Becca Nicholls about her experiences of working as a woman offshore, and how old superstitions are still very much a thing.

Thom thought he had the podcast to himself, but it turns out the professor is back after 88 days at sea. It’s time for our submarine, or human occupied vehicle (HOV) if you’re posh, special. First we reunite ‘Vegemite and Haggis’ and talk to submarine pilot Tim Macdonald about his and Alan’s undersea adventures around Australia. Manganese nodule fields, gothic cathedrals, and an undersea UFO.
We then speak with Patrick Lahey and Frank Lombardo of Triton Submarines, a bespoke submarine manufacturer, about privately owned submersibles. Initially as luxury pleasure craft but we soon find out that there is a wide range of reasons why someone would want their own sub. Throughout their careers they have had many incredible experiences, like seeing a sixgill shark give birth and communicating with bioluminescent organisms.
The podcast wouldn’t be complete without checking in with Don Walsh. He tells us about the large commercial tourist submarines which have now produced more tourist submariners than the US navy.
Glossary
Autonomous vehicle: A vehicle that doesn’t need a human pilot
Globular: Globe-like, spherical
Human Occupied Vehicle (HOV): Another term for a submarine
Hypoxic: Insufficient oxygen
Thrusters: the propellers on an underwater vehicle that allow it to move

The Professor is back on land and Dr Thom is back from Squid Christmas, what a better time to talk about the squishiest of deep sea critters? We talk with George Matsumoto from MBARI all about gelatinous deep sea species. How do we study them? How on earth can we preserve them or even capture their fragile bodies? Plus, we find out exactly what that curious little blue spiky blob was.

Natural history collections, huge archives of carefully curated specimens, are an invaluable tool for the scientific community. They are also a place where the public get to interact with active research and meet scientists. Forget what you’d imagine working in a museum to be like, no two days are the same and both the collections and the talented people who work with them are in constant demand. One day your helping design new swimwear based on shark skin, the next settling an argument at a fishing competition.
If you’re wondering what jobs are out there in science or just curious to know what goes on behind the scenes at a museum, this episode has some surprises for you.

Alan is somewhere in the middle of the Pacific Ocean and Thom has been dissecting fish left right and centre at Te Papa. What better time to talk about deep-sea digging?
After the exciting news last month about the geological cruise that drilled through the Moho (the area where the Earth’s crust meets the mantle), we thought it would be interesting to talk with Andrew McCaig, the co-chief scientist for that expedition. Andrew talks us through the expedition's goals, achievements and the drilling process itself. Why were geologists interested in reaching this area and what exactly is serpentinisation?

We also hear from two other crew members onboard the JOIDES Resolution during the 399 expedition, Igneous petrologist, Kuan Yu Lin and marine technician Luan Heywood. Kuan and Luan talk us through their experiences of working onboard the research vessel and why expedition 399 was so special.
We also hear from previous guest and great friend of the show, Ashley Rowden (his interview on seamounts can be found in episode 30). We grabbed him quickly before he chaired the deep sea session at the New Zealand Marine Science Society conference and he treated us to a great story of James Cameron’s involvement in a previous conference that Ashley was organising.

Our two favourite deep sea scientists reunite over in Wellington, New Zealand for the 10th Annual International Crustacean Conference. We speak with Kareen Schnabel and Rachael Peart about all things crabby, and the intricacies of organising and hosting a scientific conference. We also bumped into an old friend, Tammy Frank to talk about how she was finding the conference, and what she has been up to under the sea recently.
Alongside all of the conference fun, we also hear from fellow deep sea science communicator, Henry Knauber, about his scicomm efforts and experiences as an early career researcher of crustaceans.
Whilst less science-y this month, we thought it would be a great opportunity to give you an insider look into scientific conferences and their importance to research.

Tales of monsters persist to this day and there’s no better place to hide them than in the deep sea. We are joined by paleontology student and cryptozoology blogger Tyler Greenfield to look at some of the most famous sea monsters and see if there is any truth to the stories.

To finish up our run of episodes on deep-sea habitats, we’re really excited to bring you this month’s episode on… shipwrecks! But we’re not going to talk about what you expect. We all know what shipwrecks are but do you know how to find them? We talk with Leighton Rolley, an expert in researching, discovering and documenting shipwrecks. And we don’t stop there. Our second guest, Lori Johnston is a microbiologist whose research has focused on the fascinating structures of rusticles: the rusty icicles that hang from shipwrecks like the Titanic.
We’re also very happy to hear from Don in this month’s episode with his tale of sailing on the infamous ghost ship, Glub Glub Orlova.

Our short and to the point PRESSURISED version of episode 9. If you don't have time for the full episode and want to get right to the science without any of our waffle, this is the place to be!
We are both biologists and a little biased toward the deep-sea critters, but the deep ocean contains a wealth of geological discoveries, after all, it is the geology which creates the deep sea.
We have a chat with geologist and explorer (and friend of the show) Heather Stewart about the geology of the deep sea and how we produce maps of the ocean floor. Why do people talk about how little of the ocean has been mapped when we can clearly see it is all mapped on google earth?

Our short and to the point PRESSURISED version of episode 34. If you don't have time for the full episode and want to get right to the science without any of our waffle, this is the place to be!
On this month’s episode, we wanted to go deeper and darker than we’ve ever gone before… prepare the enter: the deep biosphere!
We talk with Professor Mandy Joye about the vast microbial wonderland which is the deep biosphere. This ecosystem, which exists deep under the seabed, has only recently been discovered and research is just starting to reach some interesting conclusions. We lean about the importance of deep sea microbes and how they cycle through our planet.
Professor Alan has been very busy this month with another world record to add to the collection. Not only did Thom and Alan break the world record for the world deepest fish back in 2014 (with a Mariana snailfish (Pseudoliparis swierei) being observed at 8143m in the Mariana trench). But, Alan beat his own record with this new snailfish seen at 8336m in the Izu-Ogasawara trench near Japan!

Our short and to the point PRESSURISED version of episode 7. If you don't have time for the full episode and want to get right to the science without any of our waffle, this is the place to be!
We impact the deep sea in many ways we don’t realise. Some are deliberate, some are accidental, some we didn’t even notice at the time. We talk about ways we have impacted the deep sea and touch on the huge problem that is marine plastic, a particular problem in the isolated Mediterranean Sea. His serene highness Prince Albert II of Monaco tells us about his experience diving to the deepest point in the Mediterranean, the Calypso Deep and his Beyond Plastic Med initiative.

Here’s our second episode of The Deco-Stop; a deeper look into the humans behind deep-sea science and technology. We’ve done our science dive, and now it’s time to decompress, and discuss tales at sea, career paths and the social & political aspects of deep-sea science.
From Steven Hawking to Charles Darwin, neurodiversity and science have been intertwined throughout history. Neurodiversity is a term which refers to the variety in the cognition of the human brain and can include people who are on the autism spectrum, or who have been diagnosed with dyslexia, dyspraxia, and dyscalculia, among others.
We wanted to talk on a very human level about the strengths and weaknesses of being neurodivergent in science and to also share with you some personal stories and assistive resources. Thom shares his own journey in the field, alongside many other pioneering colleagues. Living legend, Bob Ballard speaks with us about his perspective on being dyslexic and even attributes his career success (including the discovery of the titanic) to his gift.
Friends of the show, Tom Tangye, Sophie McLellan and Cat Morgan also share their experiences of working in the field alongside being neurodivergent. They share how the industry, and the world in general, is changing to be more inclusive and understanding of everyone who thinks differently.
We had such a great time making this episode, and we’re so grateful to everyone who spoke with us. Below you’ll find a whole host of resources that have been shared with us, and that we recommend ourselves!
Let’s carry on this conversation, with colleagues, friends, and with those outside our inner circles. Be patient with each other, and trust that the world is changing, for the better.
We are so excited about creating this space to talk more about the human aspects of deep-sea science, and would love to hear from you about your deep-sea journey!

Continuing with the parasitic theme, Thom and Alan share their critiques (and also their love for) ‘The Last of Us’, an apocalyptic TV show involving fungal parasitology. The news is somewhat less parasite-y this month with Alan officially extending the depth records for several taxa and there’s a new species of cavefish described! Don also provides a highly unexpected story from his days as Captain of a submarine...

Our short and to the point PRESSURISED version of episode 6. If you don't have time for the full episode and want to get right to the science without any of our waffle, this is the place to be!
Our world is rapidly changing. As we move away from fossil fuels and our use of electronics increases, demand is climbing for a handful of metals key to the manufacture of modern technology. Mining the deep sea may meet these demands but is probably the most contentious issue the community is facing right now. Is there a net benefit for the deep sea, funding research and understanding, addressing climate change, and encouraging developing nations? Or is the deep sea too fragile and too unknown to be responsibly exploited?
We bite off far more than we can chew by taking on this issue in a deep-sea mining special episode. Luckily, we have some guests we can call on to help us understand the issue. Professor Jeffrey Drazen of University of Hawai`i at Manoa explains just what deep-sea mining is and its ecological impacts. We then speak with Michael Lodge, secretary-general of the International Seabed Authority (ISA). The ISA, comprised of 167 member states and the European Union, regulates, and controls all mineral-related activities in the open ocean – that’s the majority of the planet!

This month is a fun one (maybe not if you love cetaceans) as we’re covering whale falls! That’s right, dead whales and the ecosystems they create on the seafloor. Professor Craig smith joins us to talk all about the stages of decomposition, the key species that whale falls support, and some truly wild tales from the high seas.

Professor Craig Smith joins us to talk all about the stages of decomposition, the key species that whale falls support, and some truly wild tales from the high seas.
We finally answer the big question, what smells worse: a dead whale or a dead deep-sea sponge? The answer might not be what you expect. We also hear from a couple friends of the show, including Shelly, who may have found one of the earliest comparisons of the moon and the deep sea, and Otis, who talks us through his research on the back of our last episode on hydrothermal vents.
In other news, consuming deep-sea water lowers cholesterol (this one is definitely, absolutely, 100% true), there’s a new deep-sea documentary premiering at Sundance and we made our first 30p (and a pint)! This newfound success has pushed us to release another Deco-Stop episode on neurodiversity in science, coming to you next month!

We speak to the incredible Charles “Chuck” Fisher, a pivotal biologist in hydrothermal vent research, about these fascinating habitats and the organisms which exist there. We learn about the iconic tube-worms and their specialised adaptations to life in these extreme environments. Plus, Chuck does some of his own myth-busting and sets the record straight on a common tubeworm trope.
Don shares his own experiences of these impressive habitats (and the not-so-impressive lunches that came alongside them). Buckle-up for a big one!

We’ve been off-piste for a while now so we thought we’d jump straight back into the deep sea with a series of episodes on deep-sea habitats. We’re starting off strong with a huge episode on seamounts! We speak to a friend of the show, Ashley Rowden who’s an expert in all-things benthic and we find out why seamounts are just so cool. We also get a little distracted and reminisce about the ultimate offshore championship: sausage-fest.
We get to hear from the scientists on board the RRS Discovery who are currently on an expedition to discover the life that exists on the seamounts surrounding St Helena and the Ascension Islands. A couple of our friends on board also recall their ‘crossing the line’ experience, and how they’re finding working on board a research vessel.
We have huge news! You’ll be very excited to hear that we have released a new design for our merch, featuring our favourite parasite - the tongue-eating isopod, Cymothoa exigua! A perfect gift this holiday season for the whole family.

Working in the deep sea is entirely dependent on technology and the incredible forces push engineering to its limit. If you are doing something that no one has done before, chances are you are going to have to make some of your own tools. Unfortunately, we must spend a lot more on our equipment for the same data as shallower science. This makes funding difficult but also makes the deep sea quite an exclusive club.
We are joined by James Cameron (yes, that one) to talk about solving the problems of working deep with new technology. He shares how he went about illuminating the Titanic and confesses that his films are often an outlet for the technology he wishes he could build. Some of the concepts coming in Avatar 2 are an example of this. Don Walsh joins us as ever to give his take on the importance of the engineering that allows us to do the things we do.

We hear from one of our old students about the work he’s been doing in deep freshwater ecosystems, which got us thinking about these unique environments and the kind of species that live there. We decided to throw one last curveball away from the deep sea and speak with Dr Melanie Stiassny, an ichthyologist who’s focused her research on the deep water fish of the Congo river.
We couldn’t go an episode without discussing the latest deep-sea related conspiracy theories. And of course, we hear from Don about how freshwater affects sub manoeuvres.

https://www.armatusoceanic.com/podcast/003-aesthetics-of-thedeep-sea-with-artist-alex-gould
Can we use art to help people engage with the deep sea? We stop trying to explain things and let artist Alex Gould help us see deep-sea animals for the first time all over again.
We talk about the aesthetics of deep-sea fish, is it distorted by our expectations? Can we save the blobfish from bullying? Can art help us with the horror of tongue eating parasites and fish absorbing their boyfriends?

The Professor is back from his adventures at sea with lots of exciting new updates. He talks us through some of his key findings from this already iconic deep-sea expedition. We also get to hear from an often overlooked figure in these expeditions: the ship's captain. Alan and Captain Stuart Buckle have a shared history of seagoing. Travelling the world together onboard the DSSV Pressure Drop during the Five Deeps expedition and during the Professor's recent venture to the Japanese trenches. Captain Stu talks us through his journey into becoming a captain and how he managed to bag the role of captain during James Cameron's legendary Mariana Trench dive.
We also hear from one of our favourite captains and long-time guest of the show, Don Walsh. Don recalls how he sharpened his skills in ship handling and his methods of teaching these skills to the next generation of sailors.
Deep-sea news is a mixture of policy and goo this month. Deep-sea mining tests get the go-ahead, and Alan and Thom try and figure out what a certain spiky blue goo found at the bottom of the sea might be.

Here’s our first ever episode of The Deco-Stop; a deeper look into the humans behind deep sea science and technology. We’ve done our science dive, and now it’s time to decompress, and discuss tales at sea, career paths and the social & political aspects of deep sea science.
Read the show notes and find the full episode here:
https://www.armatusoceanic.com/podcast/deco-stop-1
In our first ever episode, we talk to Kat Bolstad, the leader of the AUT lab for cephalopod ecology and systematics (ALCES) at Auckland University in New Zealand.
We talk about squid Christmas, chasing the colossal squid, Kat’s career journey and her truly incredible record of being the deepest lactating human (we think). She also tells us how she once made a liar out of Sir David Attenborough. We’re so excited about creating this space to talk more about the human aspects of deep-sea science, and would love to hear from you about your deep-sea journey!

In this episode we have an amazing interview with legendary oceanographer, Don Walsh. In 1960, Don and Jacques Piccard were the first people ever to reach the ocean’s deepest point – Challenger Deep in the Mariana Trench in the bathyscaphe Trieste. Since then, Don tends to get asked the same questions about the dive but he is full of other stories at least as interesting. Some include getting a tour of the heavens from his old dive buddy Arthur C. Clark, almost joining the Apollo Program and being involved in the first remote sensing of our oceans from space. He is still passionate about science communication and we discuss how important storytelling is when sharing science.

With the Professor out at sea, Thom goes off the rails and finally gets his answers on cave biology. What are the similarities and differences between the deep-sea and cave ecosystems? How are they linked? Do we know more about the moon than cave biolo…. just kidding! We speak to the legendary Professor Thomas Iliffe, who has shaped the field of biospeleology (cave biology); discovering over 250 species, and 3 new orders (now you don’t hear that every day)! He talks us through the formation of these habitats, what dive surveys are really like, and how to discover the most fascinating of organisms. We also hear from Martin Pollizotto, a listener (and expert cave diver) on bioluminescence in cave systems (or a lack thereof).
We had a lot of deep-sea news this month! New species are being discovered, Alvin is back in the water breaking previous depth records, we have new tech AND some interstellar news!

In the very first episode of The Deep-Sea Podcast we let you know who we are and why we felt the world really needed a podcast about the deep sea. Alan rants about how the statement ‘we know more about the moon than the deep sea’ is not just a bad analogy, it’s plain wrong. Thom talks about how the quality of scientific writing is maintained. And our guest, Prof. Monty Priede, Editor-in-Chief of the scientific journal Deep-Sea Research Part I, talks about why there are no sharks in the abyssal zone.

After recovering from you-know-what last episode, we’re excited to complete our open-water/pelagic trilogy with this week’s guest Professor Justin Marshall. Justin is an expert on all things vision, and talks us through all of the intricacies and oddities of vision in the deep sea. We discuss how fish eyes have evolved in order to adapt to the darkness of the deep, and how exactly they are able to see bioluminescence. Justin’s research has been highly influential, so we ask him more about his discoveries of mantis shrimp vision, and how he found out that cephalopods were colour-blind!
We also couldn’t let him leave without getting some of the stories from his time living in the underwater habitat for weeks, and how this led to somewhat horrifying fungal consequences.
The deep sea has seen a flurry of activity this month with lots of news to cover! MBARI has released a fascinating new video of a deep-sea squid brooding eggs. We cover some more paleo-news with surprising historical deep-sea temperatures and the discovery of new brine pools in the Red Sea.
It wouldn’t be the Deep-Sea Podcast without checking in with Don Walsh as he talks us through the history of submarine windows. And we also hear from a listener and find out how snailfish got their name.

Last episode we learned about the pelagic zone, the largest habitat on earth, a boundless 3D space where enormous migrations take place. We learned that this isn’t a world of darkness but rather one of biological light, where bioluminescence is used to attack, to defend and to communicate. While producing your own light may seem alien to us, it is likely the most common form of communication on the planet.
To learn more about this world we speak with Edie Widder, who has studied bioluminescence for her whole career and used the same adaptations found in the animals to design her own equipment. She developed the Eye in the Sea, a camera system invisible to most deep-sea animals, and a lure which emulated a bioluminescent jellyfish, the e-jelly. The gear worked extremely well and along with a lot of behaviours observed for the first time this also captured the first footage of the giant squid, Architeuthis dux.
In recent news we talk about how plate tectonics impact our climate, what we can learn from the evolution of cave animals and generating power from the thermocline. Don Walsh tells us why these bioluminescent creatures are a nuisance to submarines.

We have a confession to make. We talk a big game about how we are busting myths, tackling deep-sea tropes and showing the deep ocean as it really is… but we have been guilty of one of the big ones. The deep sea is not just the bottom! Most of the deep sea, in fact, most of the habitat of this planet is the huge open 3D environment of open water or ‘pelagic’ water. In this staggering volume the planets largest migration takes place twice a day. Animals are locked in an evolutionary arms race, using their own light to deceive and trick. Finding a meal is rare, finding a mate is rare and life is without boundaries. These factors have led to some truly wild evolution.
We hear from Don about hunting for the 'deep scattering layer' (DSL) before we even knew what it was.
In recent news we cover Edith Widder and her new book Below the Edge of Darkness, underwater GPS through the power of a pong, following the yellow brick road to meet the deep-sea wizard and some lovely new footage of a highfin dragonfish.

Sorry that this episode isn’t the perfectly polished jewel that this show usually is. Thom’s family got a visit from both COVID and chickenpox so there hasn’t been the time or energy to edit as well as he usually does. But we couldn’t abandon you without an episode this month as some great stuff is still covered.
Last episode we leaned about the pelagic zone, the largest habitat on earth, a boundless 3D space where enormous migrations take place. We learned that this isn’t a world of darkness but rather one of biological light, where bioluminescence is used to attack, to defend and to communicate.

In recent news we talk about how plate tectonics impact our climate, what we can learn from the evolution of cave animals and generating power from the thermocline. We hear from a listener about their bigfin squid archive. Larkin drops by to tell us what a ‘Tron Dolphin’ and Don Walsh tells us why those same Tron Dolphins are a nuisance to submarines.

We also tackle a couple of listener questions: Whatever happened to the word ‘nictoepipelagic’ which seems to have vanished from scientific writing? We also discuss parasites in the deep sea, how can they find a specific host when the animals are so spread out? We hear from Don about hunting for the 'deep scattering layer' (DSL) before we even knew what it was and find out where Larkin has been from her new vessel on the Gulf of Mexico.
In recent news we cover Edith Widder and her new book Below the Edge of Darkness, underwater GPS through the power of a pong, following the yellow brick road to meet the deep-sea wizard and some lovely new footage of a highfin dragonfish.
We also find ourselves talking about how the deep sea is portrayed in children’s books and learn that apparently zesty citrus and floral smells are associated with the deep ocean… who knew?!

Can we safely bring deep-sea organisms to the surface and keep them alive? Certain species, such as the giant isopods and giant Japanese spider crabs have been kept in aquaria in the past but the number of animals we can maintain long-term is quite small. The Monterey Bay Aquarium’s new Into the Deep exhibition has succeeded in keeping animals never before put on public display, some are even new to science. Not only that, but they have even had some success in getting them to reproduce! Figuring out what conditions these animals need and observing them over long periods will allow us to learn huge amounts about animals we usually only get a glimpse of. We talk with aquarists Ellen Umeda and Michelle Kaiser and life-support engineer Brian Maurer about the years of work that went into keeping these animals and giving the public a very personal deep-sea experience.
In the rest of the episode, Alan is back in the UK and we get to record in ‘the very quiet room’. We discuss data sharing and the complexities of charging for data that may otherwise not be taken, visiting the Explorers Club in New York and language barriers within science.
I also call Alan’s bluff and present him with a lovely Deep-Sea Podcast apron which he then proceeds to wear in Hell’s Kitchen in New York.
We hear from a listener about how the podcast helped them through a difficult time and answer a listener question about the danger of entanglement for undersea vehicles. If you’d like to record a question or comment please do and send it to the email below. We would love to include you on the show.

One of the most exciting parts of our job is going to places that no one has ever been before and seeing things that no one has ever seen. It turns out, we were making that far harder than it needs to be, we can do all this from home! Several of the big names in deep-sea exploration live-stream (or dive-stream if we’re being cute). With just a few seconds delay, you can see deep-sea exploration as it happens and may be present for very significant finds. You never know what you’re going to find down there.
The big players in this space are the Schmidt Ocean Institute, Nautilus Live from the Ocean Exploration Trust and Ocean Exploration/Okeanos Explorer from NOAA. We are lucky enough to chat with Kasey Cantwell, the Operations Chief of the NOAA Ocean Exploration Expeditions and Exploration Division. We talk about the amazing opportunities this new way of doing science presents. From allowing 300 experts to take part, to swapping out your expert team when you find something unexpected and even the physical and societal barriers that can be removed. But it’s not just about getting science done, it’s about sharing these experiences with everyone. Online communities are forming around these streams and illustrations, poetry and memes are just as valid outputs.
In recent news we hear how preparations are going for Alan’s upcoming cruise. We talk about the octopus garden providing a nice warm spot to brood eggs, living underwater for long periods of time and the evolution of early vamperoids.
No episode would be complete without our regular check-in with Don Walsh to hear about his involvement with the early days of ROV and AUV research.
Check out our podcast merch! Please do send in any pics of you wearing the merch. We find the idea of real people in the actual world wearing this so surreal!

We have often talked about how difficult it is the get data from the deep sea… but would you believe that the bottleneck to our understanding of the deep ocean, at least as far as visual data, is processing those images? Turning a picture of the deep sea into a list of species, habitat type, sediment type etc. is a time-consuming process that requires a wide range of skilled people.
Due to time/funding constrains a lot of valuable information is lost. A team looking at a specific question will have lots of information in their data that other teams could use.
A picture is worth a thousand data points.
We chat with Dr Kakani Katija, the co-founder of FathomNet, an open-source repository for labelled deep-sea imaging data. The platform is still in beta but it is hoped that it will allow scientists to easily and usefully share their amassed data in a single and easily searchable place.
But what about that processing bottleneck? The tech-savvy listener may have noticed that a massive collection of labelled image data is exactly the sort of thing you need to train a Machine Learning or Deep Learning algorithm. Can we automate a lot of the time-consuming image processing and let the experts focus on the new and unusual stuff? It’s at this cutting edge that things get exciting and we may be at the cusp of a marine science renaissance.
We have all our usual nonsense. Alan continues to find things in Australia that want to kill him. We answer some listener questions on deep-sea fish memory and Thom and Alan’s origin story. We also hear from Don about his time on the cruise ships. A decidedly un-deep-sea segment but it could be considered ‘adventure’ on the high seas.

It’s February, the month of love and there’s love in the deep ocean too. We talk reproductive strategies in the deep sea with Professor Craig Young, Dr Autun Purser and Dr Mike Vecchione. How do you find a mate in the sparsely populated deep ocean? How can egg and sperm meet when you are fixed growing on a rock? How can your babies disperse and find a suitable habitat, especially if you live in a rare habitat like a hydrothermal vent? We find the solutions to all these problems and more.
We also have our regular contributors. Dr Don Walsh shares how a dolphin entourage isn’t a good thing if you’re trying to be a quiet and sneaky sub. Larkin also shares how it’s difficult to keep romance on the DL when you live in the tight confines of a ship, people do love to gossip.
In recent news, we announce the launch of Alan’s Deep-Sea Research centre but get distracted by the retired yob of a bird, the Kookaburra. We also consider starting a side-hustle selling dirty deep-sea bottled water and discuss a massive icefish nesting ground found in Antarctica.
We answer Maya’s listener question, ‘are there deep-sea-sons?’ Do they even know it is the month of romance?

As promised in the Christmas special, we call the ‘squid-phone’ – a special line used by scientists globally when they seem something strange and squiddy. On the other end of that line is Mike Vecchione, the expert on cephalopods. We talk giant and colossal squid (to audible groans from Mike); the bigfin squid (Magnapinna), most famous for being the squid with the long trailing arms that’s often used as an example of terrifying deep-sea creatures, but also a species, genus and Family that Mike described and would love more sightings of.
In recent news, we worry about deep-ocean circulation and its impact on climate. Reflect on a year of amazing sightings from Monterey Bay Aquarium Research Institute (MBARI) including the giant phantom jelly (Stygiomedusa gigantea) and barreleye fish (Macropinna microstoma).
We also address a snailfish imposter. The world’s deepest fish, the Mariana snailfish is more often than not represented by an image of a totally different species that happens to have a more attractive headshot. Prema Arasu presents her poem; An Ode to the Blobfish, in honour of another species dominated by one misleading photo.
Our regular contributors drop by too: Larkin – our resident deckhand tells the tale of an impromptu squid dissection and Don Walsh reflects on piloting the super-deep diving bathyscaphe Trieste in a time when giant squid attack was still a worry.
An Ode to the Blobfish by Prema Arasu
O Psychrolutes marcidus! O gelatinous shape!
Thou art the ravish’d bride of deep-sea trawlers—
Unassuming foster child of the timeless abyss
Untimely ripp’d from thy diatomaceous womb
Fearful fishermen rejoice at thy sacrifice
An Antipodean altar attended by inchoate priest—
Then once by man and angels to be seen,
In roaring thou shall rise and on the surface die.
Were I anointed and dragged to your Hadal habitus
Flayed and deconsecrated at thy mucilaginous prow—
Were I to partake in salt’d communion
With thou, we would be one and the same.
Hideousness is a lie, lies hideousness, that is all
We know on land, and all we need to know.

We like to let our hair down a little for the Christmas episode and do something a little different. We recorded video this episode! You can find the video version of this podcast on our YouTube page. Me and Alan crack out some mulled wine and decide to interview each other for this episode. Things get a little off the topic of deep sea but it’s all in good fun (if a little dark at times).
We won’t leave you totally without some deep-sea updates though. We still have our news section which includes new research into how sponges may be able to think, a deep-sea crawler that has been tirelessly surveying Station-M for seven years, a new species of deep-diving beaked whale, a new and really nice video of the creepy bigfin squid, can rockfish help us live longer and it turns out that Terry the fat shark is real.
No episode would be complete without checking in with Don Walsh, who tells a story of a Christmas in the Western Antarctic… the far side, and Larkin who has her Christmas plans suddenly change while trying to leave her ship in Mexico.
Whatever you celebrate at this time of year, we hope you have a wonderful time. See you all again in the new year.

Our countdown timer at sea
https://www.armatusoceanic.com/podcast/018-sound
We think of the deep sea as an eerily quiet and spooky place but that isn’t completely true, animal communication, seismic activity, human noise and even the sound of rain and waves from 10 km above. We chat with undersea audio expert Dr David Barclay about the fascinating audio properties of the deep ocean. As we are talking audio data on an audio medium, lets have some fun with a game of ‘what can we grenad-hear’ where Thom tries to guess the deep-sea sound.
We also have deep-sea news: India are developing their own 6 km rated human occupied vehicle (Samudrayaan); genetics links deep-sea shrimp with their planktonic juvenile stages; the HACON project explores the Aurora black smoker field at 4000 m/13,000 ft under the Arctic; we also reveal that a mysterious squid-like creature, was, in fact, a squid.
We also discuss communication (through the medium of famous quotes). Are we losing the ability to actually engage and learn things from each other? Are we all just yelling at each other online from our respective teams? Not willing to really listen to the other side but rather ‘own them’ and drop the mic. In a pandemic of misinformation where a catchy meme can ruin, or even end, peoples lives do we have a duty to try to engage with people? What about the tole that takes on our own mental health?
Don Walsh drops by with some amazing stories from his sub commander days. A life entirely dependent on listening and being quiet. We then have a ‘tale from the high seas’ from Larkin to finish things up.

We love going to sea, it is probably the best part of the job. That’s where most of our adventures happen, that’s where most of the exciting discoveries and firsts happen and it’s where we meet some of the most interesting people. We want you to have a great time at sea too and not be put off by a bad first experience. Poor packing or a faux pas could spoil the whole experience and we don’t want that. We put together some advice for your first trip. Forgive us if parts seem patronising, they are all things we have seen spoil someone’s trip and with everything else to worry about, it’s easy to forget the simple stuff.
We chat with Larkin, a deck-hand turned youtuber about life at sea and sharing that experience through her videos. What is her average day like at sea and how’s the morning commute when your office is a small response vessel chasing a submarine 10,000 m below you? How can you get a celebratory tattoo offshore from an unqualified scientist? “Don’t worry, he’s a doctor, not that sort of doctor but don’t worry about that!”
Larkin represents the growing proportion of women at sea, a situation which has rapidly changed over the last few years. Did you know that there was a time when she would have been considered bad luck? Don Walsh tells us about the gradual changes to offshore culture that has allowed this and the female pioneers who blazed that trail for the current generation. There is still much to do, but things are accelerating.
Finally, we hear from listeners what their tips are for your first trip offshore.

https://www.armatusoceanic.com/podcast/016-biodiscovery
We are in desperate need for new bioactive compounds. Superbugs are on the rise as evolution finds a way of thwarting our antibiotics. We are also continually on the hunt for compounds that can fight disease, ease suffering or get your teeth super white. The natural world has been experimenting for millions of years and has come up with solutions far more elegant than we could come up with.
Don pops by to make us aware of bioprospecting. The ocean, and in particular the deep ocean, may be the best place to look for new compounds but is this a threat to the ocean? It is often mentioned alongside seabed trawling, climate change and mining as a threat to the deep ocean. Should we call it bioprospecting or biodiscovery and what’s the difference? If most of the world’s ocean belongs to everyone, who owns a discovery? How do we ensure that developed nations, who are better equipped to benefit from a discovery, don’t leave developing nations out? Are companies really patenting naturally occurring compounds? If we find something exciting, what is the process for it becoming the next wonder drug?
While they both agree that looking for new compounds in the deep sea sounds good, Alan and Thom are soon stumped by the complexities of actually making that happen in a fair and sustainable way. Luckily, they can call on Professor Marcel Jaspars, head of the Marine Biodiscovery Centre to help us through the practicalities of biodiscovery but also its political and ethical complexities.
As ever there will be a roundup of current news. The sex-lives of giant squid, are they monogamous? India launches its Deep Ocean Mission with the intention of starting deep-sea mining and we ponder why large surface predators would dive very deep.

We hunker down behind the blast doors and quickly record part 2 of our space episode before 426 manages to get through. That’ll make more sense once you hear the episode, or maybe it won’t! I may have gotten carried away on the sound design on this one.
We are still exploring the parallels between space and deep-ocean exploration. It feels like technology and access is really accelerating in both spheres. Don calls in to teach us about the amount of water in our solar system and the potential new job title – Planetary Oceanographer.
When an incredible piece of tech grants us access to an exciting new frontier, it can be hard to manage all the different things we would like to do. Alan relays how, on his expeditions, data is first shared with the host nations and then access is requested.
When samples or access to a vehicle is limited, how can we ensure that resources are shared fairly? We have seen it lead to disagreements on ships. With something as singular and precious as a Mars rover, how are its objectives planned? Evan Hilgemann, mechanical engineer and Curiosity Rover driver with NASA’s Jet Propulsion Lab (JLP) joins us to share how a rover is managed. We chat about the parallels between exploring mars and exploring the deep sea, the similar issues we face, what we can learn from each other and most excitingly, where is technology heading on both fronts! It turns out fleets of distributed intelligence rovers on the moon or a steam-punk rover on Venus aren’t all that farfetched. These are exciting times.

Sorry for the lateness of the episode, we were rather ambitious with this one. Thom and Alan get access to a sound stage and get to actually record the podcast in the same room for the first time. In recent news there seems to be some pop-culture discoveries, the Eye of Sauron and Spongebob and Patrick have been found in the deep sea. Finally, we try not to get too depressed about ocean warming and deep-sea mining buy considering our own energy budgets.
The topic for this double episode is, as ever, the deep sea. But this time we are talking about the deep sea… Innnnnn Spaaaaaaaace! It turns out there is deep sea outside of earth, even in our solar system. The ice-covered moons of the gas giants likely contain liquid water. How likely are they to contain deep-sea life completely independent from the life that originated on earth? What are the best candidates for alien life in our solar system? What could that life be like and why does our own deep ocean provide a perfect test bed? Thom chats with astrobiologist Kevin Peter Hand, author of Alien Oceans: The search for life in the depths of space, and director of NASA’s Ocean Worlds Lab.
How will we explore these alien deep seas? It turns out that the early versions of the vehicles which may some day explore these ocean worlds are already in development. Thom chats with Casey Machado, Research Engineer at Woods Hole Oceanographic Institution about the Orpheus AUV, the first generation of such vehicle and a new asset for the exploration of our own deep ocean.
It turns out space is big, too big for a single podcast. Look out for episode 2 next week.

Thom thought he had the podcast to himself, but it turns out the professor is back after 88 days at sea. It’s time for our submarine, or human occupied vehicle (HOV) if you’re posh, special. First we reunite ‘Vegemite and Haggis’ and talk to submarine pilot Tim Macdonald about his and Alan’s undersea adventures around Australia. Manganese nodule fields, gothic cathedrals, and an undersea UFO.
Life starts to imitate art. We chat with sci-fi author John Quentin who Alan has been consulting with while he writes his next book: The Galathea Legacy, about deep-ocean plastic pollution taking place at the site of the Galathea Expedition trawls in the Philippine Trench. A site which Alan and Tim recently dived… forcing John to tweak the draft as he strives for realism.
We then speak with Patrick Lahey and Frank Lombardo of Triton Submarines, a bespoke submarine manufacturer, about privately owned submersibles. Initially as luxury pleasure craft but we soon find out that there is a wide range of reasons why someone would want their own sub. Throughout their careers they have had many incredible experiences, like seeing a sixgill shark give birth and communicating with bioluminescent organisms.
The podcast wouldn’t be complete without checking in with Don Walsh. He tells us about the large commercial tourist submarines which have now produced more tourist submariners than the US navy.
It’s a packed episode but we sneak some news in there too. Deep-sea fishes have more variation in body shape than shallow-water fishes. A new species, genus, and family of brittle star from a lineage dating back to the Jurassic. Coelacanth can live up to a century and Mesobot, a new method for studying open water animals.

Natural history collections, huge archives of carefully curated specimens, are an invaluable tool for the scientific community. They are also a place where the public get to interact with active research and meet scientists. Forget what you’d imagine working in a museum to be like, no two days are the same and both the collections and the talented people who work with them are in constant demand. One day your helping design new swimwear based on shark skin, the next settling an argument at a fishing competition.
If you’re wondering what jobs are out there in science or just curious to know what goes on behind the scenes at a museum, this episode has some surprises for you.
Alan is still away at sea, so Thom is joined again by Dr Heather Ritchie to tacked some deep-sea news, seabed mapping, secrets revealed by snailfish genes and wandering sponges are all hot off the presses. Don also drops in with an example of when you don’t want to collect biology, on the hull of your vessel as biofouling.

Alan is stranded out in the Pacific and Thom is left to present a show on genetics, a topic so confusing to him it may as well be magic. Luckily, friends of the show are on hand. Dr Heather Ritchie is tricked into co-hosting and we talk to Dr Johanna Weston about the things we can learn about the deep sea from genetic analysis.
Alan has found a way to get audio logs to us (pretty sure a Holtzman Wave isn’t a thing) and shares what he has been up to out at sea – it turns out, a lot! Listen in for lots of exclusives. This includes an interview with sub-pilot Tim Macdonald from inside the Limiting Factor at over 10,000 m depth. We are pretty sure this is the world deepest interview. The Deep-Sea Podcast lives up to its name, the deepest podcast around.
In recent news we discuss how our immune system doesn’t recognise deep-sea bacteria (and how that may be a good thing) and Thom gushes about his new favourite thing… blackwater photography.
Don Walsh tells us about inspecting ex-soviet reactors and discovering he is standing on top of a running one and Thom and Heather tell the tale of acquiring a -80 ℃ freezer in New Caledonia.

Tales of monsters persist to this day and there’s no better place to hide them than in the deep sea. We are joined by paleontology student and cryptozoology blogger Tyler Greenfield to look at some of the most famous sea monsters and see if there is any truth to the stories. We discuss megalodon, globsters, plesiosaurs/Nessie and all manner of strange carcasses that wash up from time to time.
We have a good hard listen to The Bloop and I call upon an expert in the undersea calls of marine animals, Nicky Harris. She also has a tale from the high seas for us… a rather grizzly bit of nature in action. People in the front row will get wet.
Also in this episode, we talk about glowing sharks, the largest bioluminescent vertebrate. Soft robotics to the planets deepest places and Alan picks a fight with a polar bear, taking on The Octonauts’ very own Captain Barnacles.
Finally, we hear from Don Walsh, who shares some ocean myths that went on to have a grain of truth.

We are both biologists and a little bias toward the deep-sea critters, but the deep ocean contains a wealth of geological discoveries, after all, it is the geology which creates the deep sea.
We catch up the latest news, including life discovered 100s of km under the ice, slowing water currents, vampire squid history and the rules of naming something new, be it a species or an undersea feature.
We then have a chat with geologist and explorer (and friend of the show) Heather Stewart about the geology of the deep sea and how we produce maps of the ocean floor. Why do people talk about how little of the ocean has been mapped when we can clearly see it is all mapped on google earth?
What about some of the more unusual features that we see on the deep seabed in Google Earth, are those roads and pyramids? I have a chat with ‘my mate Dave™’, David Howell, about marine archaeology and looking for sunken human settlements.
Finally, we hear from Don Walsh, who recollects the time he used the bathyscaph Trieste to deploy devices to listen out for nuclear tests.

Working in the deep sea is entirely dependent on technology and the incredible forces push engineering to its limit. If you are doing something that no one has done before, chances are you are going to have to make some of your own tools. Unfortunately, we must spend a lot more on our equipment for the same data as shallower science. This makes funding difficult but also makes the deep sea quite an exclusive club.
We are joined by James Cameron (yes, that one) to talk about solving the problems of working deep with new technology. He shares how he went about illuminating the Titanic and confesses that his films are often an outlet for the technology he wishes he could build. Some of the concepts coming in Avatar 2 are an example of this. Don Walsh joins us as ever to give his take on the importance of the engineering that allows us to do the things we do.
In recent news, we have a new deep-sea fish, and it’s a beast with a very cool name. In honour of the Valentine’s day we talk about love in the deep sea with some different reproductive strategies. We take some listener questions and it Tails from the High Seas my old colleague Izzy talks about a wild storm and getting superstitious with your equipment.

We impact the deep sea in many ways we don’t realise. Some are deliberate, some are accidental, some we didn’t even notice at the time. We talk about ways we have impacted the deep sea and touch on the huge problem that is marine plastic, a particular problem in the isolated Mediterranean Sea. His serene highness Prince Albert II of Monaco tells us about his experience diving to the deepest point in the Mediterranean, the Calypso Deep (https://en.wikipedia.org/wiki/Calypso_Deep) and his Beyond Plastic Med
(https://www.beyondplasticmed.org/en/) initiative.
To solve these problems sometimes we have to ask ourselves difficult questions. There often isn’t right and wrong but shades of grey and nothing is ever as simple as it seems. How much of the deep sea would you sacrifice if it solved climate change? This may not be as hypothetical as it sounds.

It’s the holidays so we decided to get together, have a few drinks and tell some stories from life at sea. We even get Märvel – the barons of high-energy rock and roll on the line for a festive chat.
This is a silly/gross episode, even by our standards. There are stories of seasickness and competitive food fungus… you have been warned.

Our world is rapidly changing. As we move away from fossil fuels and our use of electronics increases, demand is climbing for a handful of metals key to the manufacture of modern technology. Mining the deep sea may meet these demands but is probably the most contentious issue the community is facing right now. Is there a net benefit for the deep sea; funding research and understanding, addressing climate change, and encouraging developing nations? Or is the deep sea too fragile and too unknown to be responsibly exploited?
We bite off far more than we can chew by taking on this issue in a deep-sea mining special episode. Luckily, we have some guests we can call on to help us understand the issue. Professor Jeffrey Drazen of University of Hawai`i at Manoa explains just what deep-sea mining is and its ecological impacts. We then speak with Michael Lodge, secretary-general of the International Seabed Authority (ISA). The ISA, comprised of 167 member states and the European Union, regulates and controls all mineral-related activities in the open ocean – that’s the majority of the planet!
We also have current news and a chat with Don Walsh, who of course it turns out, has first-hand experience with the complexities of mining in the ocean.

In this episode we explore the power of storytelling and complete the arc of our first five episodes: science communication and perception of the deep sea.
We talk with multiple New York Times bestseller Susan Casey (https://susancasey.com/) about telling a good story and engaging people with a narrative, while still being scientifically accurate. Don Walsh (https://en.wikipedia.org/wiki/Don_Walsh) is kind enough to record his thoughts on the importance of good storytellers, which of course also contains a story we never knew about Don.
Storytelling is an incredibly powerful tool, but it can be a difficult one to wield. Alan talks of some experiences where the public perception of a story was not what was expected but also the risk of not telling the story at all and of assumptions being made.
We have our regular returning segments: Recent news, which seems very squiddy this episode; tails from the high seas, where Alan is imprisoned in a seaman’s mission; and Thom tries out a new segment about the history of some deep-sea animal names.

It’s the October episode and that means it’s our Halloween Spooktacular, what better time to turn the spotlight on ourselves and wonder why humanity seems to have an intrinsic fear of the deep sea. Glenn Singleman (https://en.wikipedia.org/wiki/Glenn_Singleman) joins us to give a psychological explanation for why we feel differently about the deep sea and seem to have an aversion to it. Even some of the best documentaries seem to change their wording when talking about the deep sea.
We give Don a quick call to get his thoughts on fear, as that’s something he’s always asked when talking about the first dive to the deepest point. Finally, we have a Tails from the High Seas from Heather Stewart who, after running from some bad weather, found herself in the middle of a military exercise.

Can we use art to help people engage with the deep sea? We stop trying to explain things and let artist Alex Gould (alexandragould.co.uk) help us see deep-sea animals for the first time all over again.
We talk about the aesthetic of deep-sea fish, is it shaped by our expectations? Can we save the blobfish from bullying? Can art help us with the horror of tongue eating parasites and fish absorbing their boyfriends?

On January 23, 1960 Don Walsh and Jacques Piccard were the first people to dive to the deepest point in the ocean, Challenger Deep. Would you believe that Don's full of other stories at least as interesting as that?
We talk science communication and exploration with Don, realise that actually we do know a lot about the Mariana Trench, and we cross the equator.

‘We know more about the moon than the deep sea’ isn't just a bad analogy, it’s wrong. We talk scientific writing and Alan confesses why, after becoming the world’s deepest Brit, he was hunched emerging from the sub.
