30 Oct 2015Episode 41 - "The Nino (Pumpkin Spice Latte Season)"00:40:00

This week we talk about El Nino, what it is, how it works, and what it means for this winter. We also discuss pumpkin carving injuries on this week’s Fun Paper Friday!

ENSO El Nino Consequences
  • Triple Hurricane Picture
  • Hurricane Patricia
  • Exacerbating an already bad drought in the Pacific NW.
  • Helping to alleviate drought in the SW and OK.
  • El Nino years usually mean much lower chances of Atlantic Hurricane development and landfall
Fun Paper Friday

This week we look at experiments about how safe different pumpkin carving tools are. Not for the faint of heart!

04 Apr 2025Episode 413 - "Waterfalls I Have Loved"00:57:30
Turner Falls, Oklahoma A rare waterfall that grows outward due to travertine deposition instead of eroding backward. Formed by spring-fed Honey Creek flowing through Ordovician limestone, creating massive travertine deposits. Pe'ePe'e Falls, Hawai'i (Big Island) ~80 ft falls in downtown Hilo, part of the Wailuku River flowing between Mauna Kea and Mauna Loa. Carved into 10,000-year-old lava flows with subsequent flows creating the Boiling Pots — vertical and horizontal lava tubes. Extremely dangerous, especially after storms — known as the deadliest water in Hawai'i. Cataratas do Iguaçu, Brazil/Argentina Largest waterfall system in the world, spanning the Argentina-Brazil border. Name means "Big Water" in Guarani. Upstream from the Itaipu Dam, which generates most of Paraguay’s electricity. Itaipu — the 3rd largest hydroelectric plant globally and 2nd in power output. Bonus Waterfalls Mentioned: Cascata delle Marmore, Italy – Ancient Roman-engineered waterfall. Natural Falls - West Siloam Springs, OK Devil’s Kettle, Minnesota – Mysterious waterfall where water seems to disappear underground. Fun Paper Friday What can spacecraft learn from cats?

13 Mar 2015 Episode 8 - "Canal Side Geologist" Making Maps00:42:00
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

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.”

06 Nov 2022Episode 348 - "Hot Juicy Magma"00:42:31
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!

In this episode of the Don't Panic Geocast, we dive into the fascinating world of dolomite, a mineral that is commonly found in sedimentary rocks. They discuss the unique characteristics of dolomite and the different ways in which it is formed. We also highlight a fun paper on equine dietary preferences, which explores the food choices of horses in different environments. The paper reveals interesting insights into the feeding habits of horses and how they adapt to different conditions Fun Paper Friday Goodwin, Deborah, Pat Harris, and Nell Davidson.

30 Jan 2015Episode 2 - If you’re doing geology in pen, you’re just not doing geology right00:51:41

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 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?

Ever wondered how silver journeys from ancient rock formations to the tech in your pocket? In this episode of Don't Panic Geocast, we dig deep into the fascinating world of silver—the metal that's shaped economies, inspired legends, and powers modern technology. From its formation in Earth’s crust to the precise science of extraction and refining, we’ll explore how silver’s unique properties make it indispensable in everything from solar panels to medical tools.

01 Jan 2016Episode 49 - "Would it blow your mind if I told you Africa is 14x larger than Greenland?"00:45:07

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!

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.

13 May 2023Episode 364 - Geology of War "I'm glad I listen to this podcast"00:55:43
Join us as we explore how the intricate interplay between geology and military strategy has shaped history. We unravel the secrets behind the terrain's influence on battles, from its impact on troop movements to the potential for fortifications and natural defenses. Additionally, we investigate an intriguing question: What type of rock is the deadliest? We are astonished by the unexpected ways in which geology has played a pivotal role in shaping the destiny of nations in times of war.
