It's hard to decide when it is finally time to let go. When do you recycle that old tech and replace it? It may still work, but is it the thing holding you back, or do you just want something new and don't really need it? This week Shannon and John grappled with this exact question and talked each other into and out of some potential technology purchases Fun Paper Friday Everyone knows that physics can solve any problem if you simplify it enough, but biologists are fed up!

Forms in fractures of rocks already in place, so it an INTRUSIVE feature Form at right angles to the direction of extension in the area - nature’s frac jobs Can be super thin or super thick, but generally are self-consistent Can have multiple periods of injection or even multiple compositions of injection over time Can get en echelon patterns, rings, and cones (last two common with caldera volcanism) Magmatic are the most well known and form when magma flows into a crack and cools into a sheet. The igneous rock is generally more weathering resistant so we get cool weathering features Can be rhyolitic, but mostly basaltic Rate of cooling determines grainsize (slow = big) and big near the center Can have columnar jointing Big phenocrysts orient with flow direction - cool! AMS studies show this. These are awesome when you get them radially around a volcano! Horizontal dikes are called sills Clastic dikes are formed by sediments episode 177 (https://www.dontpanicgeocast.com/177) Can be formed with fluid pressure Cracks in permafrost that fill in Fun Paper Friday One plus one equals two, right?

Shannon just had a baby! We take the week off and celebrate with this classic episode of the geocast... Don't Panic, we'll be back next week!
Having just got back from vacationing near a river, Shannon’s mind is wondering (and wandering!) about dams and their impacts, both good and bad. People use dams for electricity, recreation, flood control, and a myriad of other things. Let’s take a look at some huge dams and what they do to both communities and rivers.
- Oroville (1968) is the tallest in the US, and earthen dam in CA 770’ high
- Hoover (1935) is next at 726’ high on the border of AZ and NV
- Tallest dam in the world is Jingping-I dam (2013) in China is 1000’ high
- Largest reservoir in the US is Lake Mead, which holds 29 million acre-feet of water
- Glen Canyon dam
- Lake Powell on the AZ/UT border, and is a close second at 26 million acre-feet capacity.
- Colorado River
- WPA
Why build dams at all? * Water supply * Irrigation and flood control * Power supply * Recreation
Hydroelectric Power * Hoover dam generates 4.5 billion kw-hr per year, serving 8 million people in AZ, southern CA and NV * Itaipu dam, on the border of Brazil and Paraguay, dams the Parana River, the 7th largest in the world. * Penstock

Having just got back from vacationing near a river, Shannon’s mind is wondering (and wandering!) about dams and their impacts, both good and bad. People use dams for electricity, recreation, flood control, and a myriad of other things. Let’s take a look at some huge dams and what they do to both communities and rivers.
- Oroville (1968) is the tallest in the US, and earthen dam in CA 770’ high
- Hoover (1935) is next at 726’ high on the border of AZ and NV
- Tallest dam in the world is Jingping-I dam (2013) in China is 1000’ high
- Largest reservoir in the US is Lake Mead, which holds 29 million acre-feet of water
- Glen Canyon dam
- Lake Powell on the AZ/UT border, and is a close second at 26 million acre-feet capacity.
- Colorado River
- WPA
Why build dams at all? * Water supply * Irrigation and flood control * Power supply * Recreation
Hydroelectric Power * Hoover dam generates 4.5 billion kw-hr per year, serving 8 million people in AZ, southern CA and NV * Itaipu dam, on the border of Brazil and Paraguay, dams the Parana River, the 7th largest in the world. * Penstock

Maps are useful things, but it turns out that projecting a 3D object on a 2D map can cause a lot of unexpected problems. They even inspired an XKCD comic. This week we explore maps and map projections. We also chat about machine learning as part of #FunPaperFriday.
What’s the big problem? * The Earth is a sphere, actually it’s an ellipsoid, actually it’s really bumpy and messy * Taking 3D information and pushing in onto a 2D medium means that you must sacrifice something, you are losing a dimension with which you can express information. * Projections are a well thought out as researched problem, even in pure mathematics. * You have to pick a projection that will tell you want you need to know accurately, and know that you lose some other information. * There is even a West Wing clip about this
A few examples of projection problems * There are geographical properties that we care about: area, shape, direction, conformality, distance, scale… and you can’t get them all at once. In fact, some it’s hard to get more than approximately the right answer. * Area: Maps that preserve area relationships between things on the globe are called equal area maps. * Distance: Some maps (equidistant maps) show an accurate distance from the center of the projection to all points. * Scale: The same scaling relation applied across the map will give accurate values for scale relations on the globe. * Conformality: Scale in any direction at any point is identical. This means that parallels and meridians are at right angles. (Local shape preserved) * http://www.colorado.edu/geography/gcraft/notes/mapproj/mapprojf.html
A few projections * Projections can be generally classified as cylindrical, conic, azimuthal, or other. These are as you would think, projections onto cylinders, cones, planes, or with rules of “rectangular meridians” or something else. There are lots of sub-classes, you can view them here. * Wikipedia lists over 60 different projections!

This week we re-visit one of our favorite shows while everyone is outside or in their turkey food-coma here in the US. We also read some listener mail about last week's episode on earthquake magnitudes!
Time is a very complex subject that you can devote your entire life to. Today we’ll cover a few of the basics and enough to get your interest up! We’ll see that it’s difficult to know what a second is and how long relative times are, but absolute time is even messier! We also discuss dried coffee and tetris!
Importance of Time (and why it’s on a geology show) * It synchronizes the world and our human interactions (need minutes - hours accuracy generally) * It allows us to talk about events in a common coordinate system * Allows synchronization of scientific measurements and comparison of data sources. This is really important for seismometers for EQ location! * Let’s us use GPS! 1 billionth of a second (nano second) error in 1 GPS satellite, GPS receiver is +/- 1 ft to satellite, which is 2–3 feet on Earth.
Early Timekeeping * Burning candles in marked cases * Hourglass * Water powered clocks * Pendulum clocks Galileo and Huygens (fancy temperature compensation as well) * Video on Galileo
Modern Time Keeping (Atomic Clocks) * First clock was ammonia maser at National Bureau of Standards in 1949, but it really wasn’t all that accurate. It was more of a proof on concept device * First cesium clock was in 1955 at the National Physical Laboratory (UK) * Leads us to the definition of the SI second he duration of 9,192,631,770 cycles of radiation corresponding to the transition between two energy levels of the caesium–133 atom * The NIST-F2, a cesium atomic fountain clock, is good to one second in 300 million years. How F2 works is a combination of feedback control loops, lasers, and really cold atoms. * Remember, atomic clocks tick away seconds, they say nothing about the hours, minutes, seconds notation we use to write time. We just define a frequency
Leap seconds * Can’t predict them far into the future because of irregularities in Earth’s rotation * Announced ahead of time in a bulletin by the International Earth Rotation and Reference Systems Service * 25 leap seconds since 1972 * Next leap second is this year! June 30, 2015 * Real problem in computing, has caused software and GPS hardware crashes/issues before * Google smears the second out over a period prior to the leap
Time Standards There are TONS of time standards, we’re only going to touch on a few. Most are known with highest precision in retrospect!
Solar time * Exactly what you would think, it’s about using the sun’s position as a time source. There is the sundial time (apparent solar time) that changes throughout the year, and the mean solar time which is like a clock time. * The equation of time represents the difference between the mean and apparent solar day * Star clock
International Atomic Time (TAI) * A measurement of proper time (it’s a relativity thing) * Weighted average of over 400 atomic clocks * If there is an error, it isn’t corrected. This makes it into terrestrial time.
Universal Time (UT) * This is what we used to call GMT! * Based on Earth’s rotation w.r.t different bodies (why there is UT0,UT1,UT1R,UT2,UTC) * UT1 is really mean solar time at the equator
Coordinated Universal Time (UTC) * Formalized in 1960 * Adjustments were accommodated by leap seconds starting in 1972 * Generally considered to be GMT, but GMT isn’t defined/recognized by the scientific community * This comes from TAI by accounting for leap seconds!
Epoch time (Unix Time) * Epoch time is the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970 * No leap seconds by definition, but implementation is actually messy * Stored is an integer (32-bits) meaning that it will run out and roll over on Tuesday 2038–01–19 One second after 03:14:07 UTC, it’s the year 2038 problem.

Place based knowledge * Connects you directly to the land. Everyone has a “place” and by further exploring it through geology it can create a deeper connection.
Time * “Any good intro geology course is actually a course in time” * Geologic time…it’s really big! * Pale Blue Dot Photo * Puts things in perspective. Carl Sagan’s Pale Blue Dot commentary does a great job of showing spatial and temporal smallness. It doesn’t make you feel small though, it makes you feel free. Chokes me up every time; Watch it here

Classes are back in session, and we’re back to normal episodes. Join us to talk about Brunton pocket transits, argue about strike and dip, and discuss the zombie apocalypse.
- AAPG abstracts are due September 24!
- Windows 10 isn’t supporting external USB microphones right now. What?
- Checkout Angie’s beautiful photos. Part 1 Part 2
What is a Brunton? * A compass, but a really expensive one with lots of features * Generally referring to the conventional pocket transit * About the size of a deck of cards, but worth $500 * It’s a very accurate compass/clinometer combination that we use to take strike and dip measurements amongst others * Can also sight bearings to objections or angle from horizontal by using the sights and mirror * Can set the magnetic declination. Just don’t forget!
Strike and Dip * Two numbers that define the orientation of a plane in 3-dimensional space using an agreed upon handedness convention * Dip direction is the direction water would run if poured on the rock, angle is how steep that rock is inclined to horizontal. * Strike is 90 degrees to dip, but conventions are mixed and messy
Azimuth vs. Quadrant * Compasses are available in two formats. * This has started holy-wars
History of the Brunton * Pocket transit invented by David W. Brunton (1849–1927) and patented in 1894 * He was a Canadian mining engineer that was tired of carrying heavy survey equipment… any of us can relate * Neat photo of early Brunton * A bunch of businessmen in WY bought it and started Brunton Inc. in Riverton. (1972) * Silva of Sweden * Fiskars (Finnish company)
Issues * Needs to have the needle weighted when at very high magnetic dip angles. * Cheap knock-off compasses are everywhere * Changed the way the needle is balanced, and oftentimes it comes unscrewed with no way to fix it. This was a change in manufacturing that many people are unhappy about.
Fun Paper Friday Zombies! This week we learn about mathematical modeling of zombie disease spread an how it relates to real world problems… mainly politics.

Intro The Orbital Mechanics highlighted how little we know about planetary formation, so let’s talk about Pluto and what we’ve learned from the New Horizons Mission.
Pluto Basics * Officially a dwarf planet in the Kuiper belt * About 0.18 the radius of Earth * Mass 0.178 of the moon’s * Very low density * Gravity 0.63 g * Neptune and Pluto were both predicted to exist from orbital perturbations of Uranus * Percival Lowell (founder of Lowell observatory) started the hunt for pluto in 1906. * Tombaugh found Pluto using a blink comparison technique * Moons of Pluto * Orbit is chaotic, we can predict forwards and backwards for several million years, but over the Lyapunov time we have no idea.
New Horizons * New Horizons Wiki Page * Launched January 20, 2006 * Fly-by July 14, 2015 * Long-Range Reconnaissance Imager (LORRI) * Solar Wind At Pluto (SWAP) * Pluto Energetic Particle Spectrometer Science Investigation (PEPSSI) * Alice (UV imaging spectrometer) * Ralph telescope * Venetia Burney Student Dust Counter (VBSDC) * Radio Science Experiment (REX)
The Glitch * July 4, 2015 the software went into safe mode * Turned out to be a flaw in the timing of the commands in the fly-by prep software. * Full functionality restored July 7 * 9 hour round trip radio delay
Glaciers/Geology * Bright heart shape observed on the side of the planet during approach is ice (Tombaugh Regio) * Nitrogen ice flows like glaciers on Earth. Water ice is very brittle at surface conditions –390 F (–234 C) * Active surface is exciting, it’s not a dead planet! * Glacier Like Flows News Article from Science
Atmosphere * As UV light from the sun strikes the thin atmosphere, eventually making tholins that color the surface of the planet * Some particles remain suspended, shouldn’t be over 30 km (20 mi) off the sfc. * Particles were found to be up to 130 km (81 mi) above the surface * Atmospheric pressure is dropping
Charon * Space.com Article * Just as geologically exciting as Pluto * Likely atmospheric in origin, but could still be geologic * Low gravity of Pluto means it won’t hold onto its atmosphere…and Charon is near its same size, so it can pick up gravitationally what Pluto is putting down. * Red coating could take less than a million years to form
Near loss of the image * Science Magazine Article * Team opened the image file, but it was of Charon. They momentarily freaked wondering if the spacecraft wasn’t in the right position. * Ended up that they were looking in the wrong directory on a FTP server.
Future * 2 months of particle and plasma instrument gathering * Will choose between two Kuiper belt objects and head that way to meet in 2019 * Data transmission home for about 16 months
Getting the data back * Tops out about 1 kilobit per second on the 70 m dishes of the deep space network * Can double the rate using different polarization transmissions from the two amps “twittas”, but something else must be shut down to have enough power to run both at the same time
Links * Super Planet Crash APOD * Pluto time tool shows you when your lighting matches that on Pluto. Tweet your photos to us and NASA! * Article Announcing Haze and Ice Flows

This week we get ready for conference abstract deadlines and talk about how we prepare abstracts. Everyone is finally back in town, but not for long!
- Pluto show next week!
- Abstract deadlines: AGU 8/5, GSA 8/11
- GSA, new topical abstracts (search visually by emoji!)
How we prepare to write abstracts * Choosing the topical material. When do you stop reporting on research?* * Think about what session to submit to * Mind maps * Outlines * Stream of conscience writing * Abstract Madlibs * Don’t do this steps hours before it is due. Leave days to mull it over * How preliminary is your data? Is it ready for an abstract?
Writing the abstract * Check the conference guidelines… then check them again. * Open an editor. John uses plain text editors initially. * Send it around for others to look at * Decide on authorship early
Tools for collaborating (a whole other show) * Google docs * Word/dropbox * Evernote (although everyone involved needs premium) * Email… if you do this, please don’t admit it
Other Notes * AGU offering free conference registration * Be sure to submit a 5-minute Pop-Up Talk
Problems * How to pick a session (look for others you know?) * Submission system crashing * Getting people to edit it! * Over-reporting
Fun Paper Friday This week we read about recovering old sounds from recordings with a microscope. Also hearing cursing at lab instruments in the old days. Nothing changes.

- Midichloria mitochonreii
Note Taking Systems * Don’t bother with highlighting, underlining, re-reading, etc. Those have been shown to be ineffective. (Dunlosky et al., 2013) * Bullet Journal * Outlining * Cornell Method * Sketch Notes. There is a book and workbook by Mike Rohde available to help you learn. * Mind Mapping
Note Taking Tools Digital vs. Analog * We can talk about the advantages and disadvantages of each forever. * Digital is re-workable (like lasso and move in penultimate). * Paper is easier to write/shade/make more detailed and elegant notes * Digital can embed media * Paper doesn’t crash or run out of battery * Digital can be backed up against loss
Digital * iPad * Apps to write or type (omnioutliner for example) * Smart pens like the Neo smartpen or the Livescribe * Apps on laptops
Analog * Good notebooks include Moleskine, Field Notes, Rhodia, and Whitelines * Pen and pencil are important. John likes Palomino Blackwing 602 pencils and the Lamy Safari pen with Noodler’s ink. * There was an excellent episode of Technical Difficulties that discussed pens, paper, and how they preserve notes. * If you are into pens, there is also The Pen Addict Podcast

Tides pull and deform the surface of the ocean and the surface of the Earth. This week we’ll take a quick tour of tidal forces, address some show feedback, and then talk about a revision on a classic physics problem.
Tides * Tides are a result of gravitational interaction of the Sun-Earth-Moon system, but are of course a factor on many other planets as well. * Gravity is the key to remember and that it varies linearly with mass, but with the inverse square of displacement.
Ocean Tides * The most familiar example is ocean tides. These are important for commerce, safety, and for sedimentary processes. * Sedimentary layers called tidal rythmites * Cool tide visualization from Calculated Images * General cycle is a flood tide raises water levels until high tide. Then an ebb tide takes water back out until low tide is reached. When the tidal stream stops and reverses it is a slack tide. * Generally occur with 24-hour or 12-hour period, can have a complex shape. * Another kind of clock, a tide clock, has been made to show this. * Spring tide has nothing to do with the season. * When planets are aligned, it’s called a syzygy. Word of the week. * A really nice mathematical introduction can be found here.
Tide Gauges * A pole with markings that we read off of * A float and weight on a pulley attached to a paper chart recorder * Pressure gauges or bubbler pressure measurement * Acoustic gauges or radar gauges (time of flight) * There is a whole mess of datums and standards that go into this, but let’s not go there today! * And rocks of course!!
Solid Earth Tide * The same forceings as ocean tides, but we are actually moving the surface of the planet here. Very important for GPS and scientific measurements. Large particle accelerators actually compensate for their deformation. * The largest displacements are around 55 cm! * Needed to explain the Earth’s nutation * Lunar Tidal Heating
Tidal Locking * We can only see one side of the moon because it is tidally locked. It rotates at the same rate that it orbits the Earth. * Checkout the Minute Earth video on tidal locking!
Feedback/Followup * We got an audio suggestion from listener Stacey about Episode 2 (field gear). She suggested attaching your field pencil to a retractable ID clip so you don’t lose it. * John has an update on the Jot Script 2 stylus!
Fun Paper Friday We’ve all had to solve the classic physics problem of what would happen if you dug a tunnel through the center of the Earth and jumped in. The classic answer has been that you’ll move like a damped oscillator and that your fall will take about 42 minutes. By improving some of the assumptions that are used, that answer has been improved.

Kelvin-Helmholtz Instability * The Kelvin-Helmholtz Instability * The Brunt Väisälä frequency
Story Updates and Feedback * Nasa has decided to go with the boulder snatch technique for an asteroid mission launching in 2020 * If you like space news and talk, checkout “The Orbital Mechanics” podcast. * A very early copy of William Smith’s map has been rediscovered at the geological society. You can view a digitized version of the map online. * More on the mysterious radio bursts * We got some feedback about levels (thanks Celena B.) and a problem with the show logo (thanks Ross K.). We hope we have corrected both. Please keep the feedback coming in!
Severe Weather * We encourge you to learn your way around and use the National Weather Service webpage. * Also checkout the National Severe Storms Laboratory and the Storm Prediction Center. * For one of the most severe weather prone areas, Oklahoma, these three organizations are co-located in the National Weather Center * Communicating weather information, or an probabilistic information is actually really difficult. * Doing a hand analysis of data is still crucial to weather prediction. For example the analyst knows about isobar kinking. * Oklahoma Mesonet * Checkout the email “The Ticker" from the mesonet * Checkout if your local weather service office offers storm spotter training classes and get to know your branch meteorologist * John had a relevant blog post that talked about what an expert is and how important it is to know the fundamentals. * Have a disaster plan and know what to do during an emergency! This applies to field geology work just as much.

We’ve both been on the road recently and decided to cut together a show to share our travels with you. This week Shannon will take us into the field in NM with her students, and John will take us to Lamont for a seismology student workshop.
Shannon’s Trip Shannon took her mapping class to the field for a mapping exercise. Her trip went far better than imagined.
- Palo Duro Canyon “The Grand Canyon of Texas"
- Field Guide for NM Site
- A surprising number of student’s hadn’t been camping before, but the school’s rec. center will rent camping equipment out to students.
- BLM Hoodoo trail hike
- Students got to look for gastroliths
John’s Trip John was at the Third Annual Seismology Student Workshop at the Lamont-Doherty Earth Observatory. We got to interview one of the organizers, Zach Eilon.
- A few of the talks that appealed to the instrumentation nut in John were about the MERMAIDS project and using trains as a seismic source.
- Organizers had students introduce themselves and make a crowd-sourced mind-map of what people wanted to talk about in breakout sessions. This worked incredibly well and there were many great discussions.
- There is also a google doc setup so that everyone can continue discussing and recommending papers related to discussions we had.
- John met more people interested in combining science and technology development in their academic career.

What is a geologic map? * Conveys many sorts of geologic information * The whole basis of field geology * Can be a surface,bedrock, subsurface, resource, soil, etc. map
Making the Map * Start off with your field gear…like we talked about in episode 2. We said episode 1 in the show, but that was wrong! * Have a base map (Geomorphologic map—we call these topos)…you need to know where you are at * You can use an iPad/GPS with pre-loaded topo maps, or you just have your paper basemap. * John likes the Garmin 62S GPS unit * You don’t want to become too reliant technology in the field because it could be a life or death situation * You need to have done your research before you go
History of geologic maps * Book: The map that changed the world, by Simon Winchester * 1793 William Smith (http://en.wikipedia.org/wiki/William_Smith_(geologist), who was a surveyor working for canal builders, was paying attention to all the layers of rock that he was digging through * He noticed that he could trace the different layers of rock that were stacked on each other * He also noticed the different fossils inside them meant that the rocks were the same age and could be traced all over * Would study coal seams, which could be easily traced and spent much time in coal mines all over England * His work was highly plagiarized, causing him to go bankrupt and into debtor’s prison * Bestowed the Wollaston Medal by the Geological Society of London in 1831 * Known as the father of English geology
Modern Tools * USGS mapview * Aerial Photos * Drones
Fun Paper Friday This week we go over a paper that discusses one of Shannon’s favorite sayings: All Models Are Wrong, but Some Are Useful, Field (2015)
Three main points:
1) “Given all models are wrong, what we really hope is that any new model is more useful than its predecessors and that the value added exceeds the total development costs.”
2) “It still remains to be seen how long we will need to wait for definitive results on usefulness under various conditions.”
3) “Not only are all models wrong, but their relative usefulness varies depending on location and the specific loss metric of interest.”

This week we talk about how sciences can weight a planet, discuss gravity, and the explosion of a military weather satellite while in orbit.
Weather Satellite Explodes
Ways to Measure Planetary Mass * Geometric (size and density), this doesn’t always work well * By triangulation and measurement of orbits of natural or artificial satellites.
Gravity * All stems from Newton’s Law of Gravitation. Which is really a controversy between Newton and Hooke. * Gravitational constant based on the Cavendish torsion balance experiment. * Measurement of the constant is difficult since it is small and we cannot measure outside of a gravitational field. * With this and Kepler’s Laws, we can solve most simple problems by hand!
Planetary Ranging A variety of ranging techniques can be used, including:
- Radio reflection
- Laser reflection
- Triangulation
Fun Paper Friday THE ASTEROID REDIRECT MISSION AND SUSTAINABLE HUMAN EXPLORATION, Gates et al.
This week we talk about capturing an asteroid with a bag and a pull string, or a spider like lander. The asteroid is then explored and moved into a lunar-like orbit for further study. The best part of all is that the ship will have an international docking system so anyone can go do science. A step towards open source science!

Time is a very complex subject that you can devote your entire life to. Today we’ll cover a few of the basics and enough to get your interest up! We’ll see that it’s difficult to know what a second is and how long relative times are, but absolute time is even messier! We also discuss dried coffee and tetris!
Importance of Time (and why it’s on a geology show) * It synchronizes the world and our human interactions (need minutes - hours accuracy generally) * It allows us to talk about events in a common coordinate system * Allows synchronization of scientific measurements and comparison of data sources. This is really important for seismometers for EQ location! * Let’s us use GPS! 1 billionth of a second (nano second) error in 1 GPS satellite, GPS receiver is +/- 1 ft to satellite, which is 2–3 feet on Earth.
Early Timekeeping * Burning candles in marked cases * Hourglass * Water powered clocks * Pendulum clocks Galileo and Huygens (fancy temperature compensation as well) * Video on Galileo
Modern Time Keeping (Atomic Clocks) * First clock was ammonia maser at National Bureau of Standards in 1949, but it really wasn’t all that accurate. It was more of a proof on concept device * First cesium clock was in 1955 at the National Physical Laboratory (UK) * Leads us to the definition of the SI second he duration of 9,192,631,770 cycles of radiation corresponding to the transition between two energy levels of the caesium–133 atom * The NIST-F2, a cesium atomic fountain clock, is good to one second in 300 million years. How F2 works is a combination of feedback control loops, lasers, and really cold atoms. * Remember, atomic clocks tick away seconds, they say nothing about the hours, minutes, seconds notation we use to write time. We just define a frequency
Leap seconds * Can’t predict them far into the future because of irregularities in Earth’s rotation * Announced ahead of time in a bulletin by the International Earth Rotation and Reference Systems Service * 25 leap seconds since 1972 * Next leap second is this year! June 30, 2015 * Real problem in computing, has caused software and GPS hardware crashes/issues before * Google smears the second out over a period prior to the leap
Time Standards There are TONS of time standards, we’re only going to touch on a few. Most are known with highest precision in retrospect!
Solar time * Exactly what you would think, it’s about using the sun’s position as a time source. There is the sundial time (apparent solar time) that changes throughout the year, and the mean solar time which is like a clock time. * The equation of time represents the difference between the mean and apparent solar day * Star clock
International Atomic Time (TAI) * A measurement of proper time (it’s a relativity thing) * Weighted average of over 400 atomic clocks * If there is an error, it isn’t corrected. This makes it into terrestrial time.
Universal Time (UT) * This is what we used to call GMT! * Based on Earth’s rotation w.r.t different bodies (why there is UT0,UT1,UT1R,UT2,UTC) * UT1 is really mean solar time at the equator
Coordinated Universal Time (UTC) * Formalized in 1960 * Adjustments were accommodated by leap seconds starting in 1972 * Generally considered to be GMT, but GMT isn’t defined/recognized by the scientific community * This comes from TAI by accounting for leap seconds!
Epoch time (Unix Time) * Epoch time is the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970 * No leap seconds by definition, but implementation is actually messy * Stored is an integer (32-bits) meaning that it will run out and roll over on Tuesday 2038–01–19 One second after 03:14:07 UTC, it’s the year 2038 problem.

This week we discuss the geologic time scale, meteorites, and fitness trackers!
Pittsburgh Fireball Feb. 17, 2015 * Video of meteor * Article with details of entry * Animation from meteor’s perspective * NASA Fireball Network
Geologic Time-it’s really big (and deep) * The geologic time scale * Despite all kinds of fun things to demo how vast it is…still hard to understand * Cosmic Calendar * Pneumonic devices for timescale-and why do we need to know it? (several examples) * We make all kinds of assumptions about rocks that span millions of years, but an outcrop can change over the course of just a few years/ten years * Example of things changing in days to hours * Time’s Arrow, Time’s Cycle
How do we begin to define Geologic time? * International Commission on Stratigraphy: “ International Geologic Time Scale; thus setting global standards for the fundamental scale for expressing the history of the Earth” * We have to have a baseline so that we can all talk about the “same” rocks across the world
Age-dating rocks * Many techniques, and the actual dates between our epochs change all the time as our age-dating techniques evolve * Many periods/eras/epochs are marked by “catastrophic” occurrences, hence making them natural boundaries, but the dates change. * 5 major extinction events
Time as an arrow v. time as a cycle * Catastrophism vs. uniformitarianism and gradualism * Constantly evolving and vastly interesting * Thinking about the definitions of time and how we as humans try to grasp the enormity of geologic time in particular is humbling.
Fun Paper Friday * In an attempt to prolong our time on Earth, we’ll talk about accuracy of fitness apps. (John wears a Fitbit Flex and uses the Fitbit Aria scale.) * “Accuracy of Smartphone Applications and Wearable Devices for Tracking Physical Activity Data”, Case et al., Feb 2015, Journal of the American Medical Association
- Technicians at the KGRK weather radar encountered a rattlesnake during an upgrade this week. The official NWS statement says “DUE TO COMPLICATIONS INVOLVING A RATTLESNAKE DURING TODAYS UPGRADE…THE KGRK RADAR WILL REAMIN DOWN THROUGH THE OVERNIGHT HOURS AND POSSIBLY INTO WEDNESDAY AFTERNOON.”
Why should you backup? * Not lose your data * Not waste money, effort * Legal obligation (taxes, grant data policy, etc)
What makes a good backup? * Local and offsite * Multiple backups * Harward and software independence * Copies of raw and processed data (if possible) * Archivable formats * Incremental snapshots and clones
It’s not okay to “backup” versions of files like this!
Backup Solutions * Backblaze (cloud, $50/yr) - This is what John uses for one of his backups * Carbonite (cloud, $varies) - Not carbon copy cloner as said in the show * Time Machine for Mac - Another backup method John uses * Super Duper (Mirroring) * Carbon Copy Cloner (bootable backups)
Fun Paper Friday * The Earth’s core is complex with possible tectonics happening at the inner core interface. * Also, the inner core has been divided into two regions with the names: outer-inner core and inner-inner core. * Geophysics: Tectonics in the Earth’s core (Olson, 2009) * Equatorial anisotropy in the inner part of Earth’s inner core from autocorrelation of earthquake coda (Wang et al)

Feedback * We received an article from listener Hannah about using tech in education. Thanks Hannah!
Interview with Nick Holschuh Nick is a graduate student at Penn State. He tells us about his field experience, getting to Antarctica, and dealing with equipment malfunction in the field!
Fun Paper Friday * Dread Risk, September 11, and Fatal Traffic Accidents * Economic theory is built on the idea that humans, in aggregate, behave rationally. But in individual instances, under specific conditions, we find that humans rarely exhibit rationality, and so the study of these individual instances of decision-making gave birth to its own field (Behavioral Economics). It is super interesting, and is relevant to the world of science policy and public education. Here’s a crazy example of what we, as humans, do, when we fail to be rational.

This week we discuss field tools - everything from clothing to pens and notebooks! Shannon panics due to Earth’s close encounter with an asteroid and John talks about the smell after rainstorms. We want to hear your feedback!
- John has been playing more with radar during the northeast blizzard.
- Shannon has been keeping an eye on asteroid 2004 BL86 as it passed near the Earth Monday. There are already a lot of neat radar images coming from this event.
- Shannon is also planning her first class field trip for a field methods class.
Field Packs * People use everything, backpacks, fanny packs, etc. * John has a holster thing like SWAT teams. Looks a little like a weapon holster though, so be careful. (He also can’t find anyone that still sells them.) * Shannon uses a wait-pack. * John and Shannon use stretchy belts to hold their hammers. * Lots of folks use their hammer as a ruler in the field.
Clipboards * John has a clipboard with storage under it. The black ones gets really hot in the sun though. * Shannon uses a taped together fiber-board/lexan map board. It’s large!
Field Clothing * Clothing tech revolutionized geology! * Drilling with quick-dry pants vs. carrying rainsuits that you sweat in anyway. * All drab colors! Consider wearing a safety vest! * Hat suggestions? Maybe we should go back to full academic dress? * Polarized sunglasses are a must. Just beware that they can alter the color of things!
Field Notebooks * Traditional Write-in-the-Rain/Field books. Shannon doesn’t like these because of pencil writing quality. * Extras in the back of different series of notebooks can be problematic * Notebook closures: Binder clip, rubberband, or elastic over notebook * If you’re really into this stuff, you would probably like the Pen Addict Podcast. * Do you attach your pen/pencil to your field book? * Pocket protectors, John has the stealth.
Writing Instruments * 0.5 mm pencils for writing in the field books * For sketching/musing Palomino Blackwing 602 * Shannon misses the Zebra301 ultra
Compasses/Hand-lenses * Bruntons are the standard, with really no substitue * Handlens are now available with led lights (and uv if you’re that into it) * iPads vs. regular topo map concerns * Battery life * Weather resistance * Overheating * GPS (integrated or separate) * Does it take too much away from basic navigation skill development?
Fun Paper Friday * “Aerosol generation by raindrop impact on soil” Nature Communications, Jan 2015 * There is great high speed video to go with the paper. * Carl Sagan did his own version of outside of field reading! See his notes. * A good fiction work to start with is “The Martian”

Episode 1 - Clippy is Gone Now, Clippy Was Not a Help We discuss paper writing, figure making, debate the merits of our favorite software, and discuss a possible explanation of last week’s mysterious booms in Oklahoma. Shannon also discovers that John does strange things with his spare time and a police radar gun. We discuss the demise of clippy, the MS Word virtual assistant.
- Global Warming Trend Graphic
- John’s blog post on using a police radar gun for raindrop speed
Paper and Report Writing * John uses LaTeX, specifically MacTeX * Shannon uses MS Word mostly * There is value in features like track changes, scripting, distraction free environments, formatting, figure numbering, etc. * John uses markdown initially to have a distraction free writing environment (in the atom editor) * LaTeX help is easy to find!
Poster and Figure Making * Many options, but some are better than others * Powerpoint (please don’t use this for posters or figures) * Adobe Illustrator (expensive, steep learning curve, but good) * Inkscape (free clone of Illustrator at the slight expense of install/usability headache) * Photoshop * InDesign * KalidaGraph * IGOR Pro * Python * Plot.ly
Update on Oklahoma Booms * There was talk that these could have been a result of a thermal inversion * Demo of how sound bends in an inversion can be found on Dr. Dan Russell’s site and this YouTube video. * Civil War may have been influenced by acoustic propagation. There is a summary article and book about it. * We found a 1984 newspaper article from Oklahoma mentioning this phenomena.
