Episode 365 - Salinity Crisis "Smoking Various Meats and WWII"

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.

John Leeman and Shannon Dulin discuss geoscience and technology weekly for your enjoyment! Features include guests, fun paper Friday selections, product reviews, and banter about recent developments. Shannon is a field geologist who tolerates technology and John is a self-proclaimed nerd that tolerates geologists.

I listen during the data entry parts of work and it keeps me entertained.  I laughed out loud at the one newton in a square meter = a pascal joke.

Great banter

Great, topical insight on geoscience with fun hosts.

Episode 43 - “Life should be more than turning off drop shadow defaults”

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”  Contact us: Show - www.dontpanicgeocast.com - @dontpanicgeo - show@dontpanicgeocast.com John Leeman - www.johnrleeman.com - @geo_leeman Shannon Dulin - @ShannonDulin Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of our employers or funding agencies.

Extinctions are pretty common in the rock record, but there are 5 times in Earth’s past where more than 50% of the life on Earth died, these are known as mass extinctions.

Episode 30 - "YouTube is rife with turbidite videos" 

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.
