This week it’s hot… so hot that some airplanes cannot takeoff. We talk about atmospheric density and density altitude, as well as look into some histograms of what’s in your bellybutton!

This week, we mix things up a bit. This joint show between Embedded.fm and the geocast explores what happens when electrical engineering meets geoscience in cold places. We’re joined by guest Dr. Sridhar Anandakrishnan of Penn State to talk about geopebbles, ice, climate, and more!

This week Shannon pops a surprise interview on John, asking all about open source. We talk about what it is, why people do it, and what it means for your cat videos. We round out the show talking about a physics problem that has stumped some of the greatest minds.

This week Dr. Uri ten Brink joins us to talk about his field experiences as an observational geophysicst and some thoughts about being a scientist. (Sorry, no fun paper this week - we were not able to record it before Shannon’s leave of absense!)

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.

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

Write us a geoscience themed limerick! This is a family show, so remember…nothing that rhymes with “Nantucket” Please email us your limericks by August 12, 2016 and we’ll be judging them along with Dr. Katie Schearer, an english professor. The prize? One of the awesome creations from Chris at Taylor Custom. Thanks for listening everyone!

John is installing his weather station and Shannon is still pushing through finals week. On this week’s show we talk about a listener question regarding fulgurites. Can you petrify lightning and study it? Thanks to listener Steve for the show topic and fun paper suggestion!

Shannon takes one more field trip and John is ready to hit the road again, but we slow down to talk about metamorphic rocks - and probably get in trouble with the geochemists again.

John is off teaching a workshop and Shannon is working towards the end of the semester. We take a little time off to talk about academic service - what is it and why do we do it? Being an academic isn’t all fun and games!

What is “flyover country”? Is it the states in the middle of the US? A band name? A geoscience education app? One of these is true and the creator joins us to chat about it. A big thank you to listener Gary for pointing us to this topic!

How many students will ever make a professional geologic map? Not many most likely. Is it still essential to learn? You bet! This week we discuss why and how it’s done.

This week Jay Minton stops by to tell us about working at some of the largest boy scout camps around and all of the planning that goes into nature trails. Shannon brings us another fun paper from BMJ and John laments about painting.
