Ever wondered how geologists figure out when a landslide happened? Or how ancient river terraces and glacial deposits get dated? This week, we dive into the detective work behind dating geomorphic features! 🌍🔬 From tree rings to cosmic rays, we explore the fascinating methods geologists use to reconstruct Earth’s history and assess natural hazards.

Why Dating Landslides and Other Features is Hard
- Landslides can reactivate multiple times, fluvial deposits get reworked, and glacial features have complex histories.
- What are we really dating—the event, the material, or the last exposure?
Dating Techniques in Geology
- Dendrochronology 🌲 – Tree rings reveal landslides, floods, and debris flows.
- Radiocarbon Dating 💀 – Organic material like charcoal and buried soil horizons provide time markers.
- Optically Stimulated Luminescence (OSL) 🌞 – Measures when quartz grains were last exposed to sunlight.
- Cosmogenic Nuclide Dating ☄️ – Tracks surface exposure using cosmic rays.
- Other Methods – Lichen growth, volcanic ash layers, and earthquake trenching.

Fun Paper Friday

This week's Fun Paper Friday features a study on the leaf-mimicking abilities of Boquila trifoliolata. The vine is capable of changing the shape and size of its leaves to resemble those of neighboring plants, potentially as a form of camouflage against herbivores. But the most surprising part? It can even mimic artificial plastic leaves. This finding challenges existing theories that leaf mimicry is driven solely by chemical signaling or genetic exchange between plants, suggesting instead that Boquila may possess a form of plant vision through specialized light-sensitive cells called “plant ocelli.” This discovery opens new possibilities for understanding plant sensory and adaptive behaviors.

kd5wxb@gmail.com (John Leeman and Shannon Dulin) — Fri, 02 Dec 2022 14:00:00 -0500

How deep have we actually drilled into the Earth? Turns out, not very far, just 12,262 metres (40,230 ft) or about 0.3% of the way to the center of the Earth. We talk about the challenges of this feat and about potty training cows.

Episode 349 - "That Sounds Heavy" Tech Replacement

kd5wxb@gmail.com (John Leeman and Shannon Dulin) — Fri, 18 Nov 2022 10:00:00 -0500

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

Episode 348 - "Hot Juicy Magma"

kd5wxb@gmail.com (John Leeman and Shannon Dulin) — Sun, 06 Nov 2022 10:00:00 -0500

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
Can be formed with fluid pressure
Cracks in permafrost that fill in

kd5wxb@gmail.com (John Leeman and Shannon Dulin) — Fri, 19 May 2017 06:00:00 -0400

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.

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/mapproj_f.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!

Episode 45 - Revisit "What if you calibrated your candles differently?"

kd5wxb@gmail.com (John Leeman and Shannon Dulin) — Fri, 27 Nov 2015 19:00:00 -0500

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.

kd5wxb@gmail.com (John Leeman and Shannon Dulin) — Fri, 18 Sep 2015 06:00:00 -0400

This week we discuss how geoscience can enrich anyone’s life. Join the discussion and then learn about how much cosmic dust falls on us every day!

John was on The Orbital Mechanics Episode 24 talking about SMAP.

Why Learn Geology

Your World Rocked (Slate)

Spatial thinking/reasoning

Thinking in 3D is hard… 4D is harder
3D Mouse

Resources

We need resources for our modern lifestyle
Earth is continuously changing (as pointed out in the article), so preserving it as is should NOT be the goal, but preserving a habitable planet.

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

Episode 32 - "I mean, they still make rulers with inches too"

kd5wxb@gmail.com (John Leeman and Shannon Dulin) — Fri, 28 Aug 2015 06:00:00 -0400

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

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

Taking notes is an essential part of your job, no matter what you do. This week we discuss note taking strategies, supplies, and how we work. Also don’t miss out on a sticky #FunPaperFriday!

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.

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

Episode 12 - "You want to filter out the ducks" Tides

kd5wxb@gmail.com (John Leeman and Shannon Dulin) — Fri, 10 Apr 2015 06:00:00 -0400

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.

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.

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.

kd5wxb@gmail.com (John Leeman and Shannon Dulin) — Fri, 27 Mar 2015 06:00:00 -0400

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.

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.

Episode 8 - "Canal Side Geologist" Making Maps

kd5wxb@gmail.com (John Leeman and Shannon Dulin) — Fri, 13 Mar 2015 08:00:00 -0400

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

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.”

Episode 7 - "We don't have ancient Greeks on other planets"

kd5wxb@gmail.com (John Leeman and Shannon Dulin) — Fri, 06 Mar 2015 06:00:00 -0500

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:

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!

Episode 6 - "What if you calibrated your candles differently?"

kd5wxb@gmail.com (John Leeman and Shannon Dulin) — Fri, 27 Feb 2015 06:00:00 -0500

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.

Episode 5 - "We actually don't call it the Tertiary anymore"

kd5wxb@gmail.com (John Leeman and Shannon Dulin) — Fri, 20 Feb 2015 06:00:00 -0500

This week we discuss the geologic time scale, meteorites, and fitness trackers!

Pittsburgh Fireball Feb. 17, 2015

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.)

Episode 4 - "Is that cumulonimbus cloud storage?" Data Backups

kd5wxb@gmail.com (John Leeman and Shannon Dulin) — Fri, 13 Feb 2015 06:00:00 -0500

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)

Episode 3 - “Computers don’t like -20 degree temperatures” with Nick Holschuh

kd5wxb@gmail.com (John Leeman and Shannon Dulin) — Fri, 06 Feb 2015 06:00:00 -0500

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.

Episode 2 - If you’re doing geology in pen, you’re just not doing geology right

kd5wxb@gmail.com (John Leeman and Shannon Dulin) — Fri, 30 Jan 2015 01:00:00 -0500

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.

Episode 0 - “Hello World!”

In this episode, we discuss what this podcast is, who we are, and wrap up our conference travels. We also throw out our nominations for this week’s “Fun Paper Friday.”

The Podcast

We’ll be discussing: - Recent news/discoveries in geoscience - Technology that helps get the job done - Interviews with leaders in the field or interesting people - Conference stories - Bantering about any geo vs. tech topic - #FunPaperFriday articles

This podcast is for anyone working in, interested in, or vaguely associated with the Earth sciences. As Click and Clack the Tappet Brothers would say, we will often discuss things “unencumbered by the thought process.”

Who we are

John Leeman and Shannon Dulin, meteorology and geology geeks.

Winter Conference Wrap-Up
GSA - Vancouver, BC

Woolard Award winner-using paleomagnetism and continental reconstructions to determine how extinctions occurred.
Digital poster sessions integrating google earth and structural geology
Digital posters showing how drones are becoming more used to bring geology to students

AGU - San Francisco, CA

Nearly 24,000 people, about 30% students!
Interesting talks on friction as a fracture process, coaxial cable Bragg grating strain-meters, and slow-slip being stopped by earthquakes in NZ.
John co-chaired a student pop-up session and presented both science and a fun talk on using sensors in education. You can build a copy of his 3D Compass.
