00:00:00 - In our final AGU episode, Abe and Ryan host a roundtable discussion with some of the researchers who took the train from Scripps Oceanographic Institute (@scripps_ocean) in San Diego all the way to DC as part of their #trAinGU initiative that they've been doing for several years now. You may have gotten a glimpse of this chat if you follow us or Scripps on twitter. In no particular order we chatted with:  Wesley Neely (@SIOHydrogeodesy), Adrian Doran, Dara Goldberg (@dara_berg_), and Margaret Lindeman (@maaahge).

We begin with their science, each of there abstracts can be read here (they're in the same order as listed above):

• The Ups and Downs of California’s Central Valley from GPS-enhanced InSAR 

• Lateral heterogeneity of the upper oceanic lithosphere surrounding Hawaii 

• Multi-Sensor Natural Hazard Structural Monitoring at the UC San Diego Geisel Library 

• Ocean Warming Drives Increased Mass Loss at 79 North Glacier, Northeast Greenland 

00:37:40 - Joe enjoys another drink from his local poke place, this time a ume juice drink. Ryan and Abe are sharing a Partner Ship collaboration beer from Heavy Seas and Maine Brewing Co., who contribute a portion of the proceeds to the Clean Water Fund, and that seems like a no brainer as a good thing.

00:43:50- And then we talk about why taking the train to scientific meetings can send an important message about how we each manage our own personal carbon footprint as well as how much fun a multi-day train trip sounds. You can see tweets from past trips and follow along the next time they embark with the hashtag #trAinGU.

01:02:07 - PaleoPOWs are a lot like train journeys, they’re best when they stay on the rails. We begin with the immense pleasure of grating a BSSO, this time to Patron Leah A. The title of her thesis is: Testing the efficacy of supersonic nuclear-powered mag-lev trains as high-capacity rapid evacuation vectors during massive tectonic events: derailing the strike-slip damage of the San Andreas. Thanks, Leah! Next, Abe has an e-mail from IRL friend of the show Morgan Marshall, who has questions about a certain city-wide destruction movie starring Dwayne Johnson, which doesn’t narrow things down as much as one might think. And Joe reads an impromptu tweet about the show from artist Kat MacDonald (@macdokat) which just gives us all the warm and fuzzies. Finally, a brief reminder that the back catalog of Joe’s show Technically Speaking is still available on Soundcloud here.
