Monday, October 13th, 2014 - Dr. Sean Gulick uses sub-seafloor imaging tools to understand Earth history

19Oct

Dr. Sean Gulick, a research professor at the University of Texas Institute for Geophysics, sat down with us to talk about his research that deals with plate tectonics and its interaction with various systems such as erosion from mountains, glaciers and regional climate. The main tools that Dr. Gulick uses is 2D and 3D seismic imaging of the sediments and rocks beneath the seafloor to study the imprint of plate tectonics and the mechanisms through which it is manifest. Dr. Gulick went into detail about some of his recent projects offshore Antarctica and Alaska, and also talked about his work mapping the K-Pg impact crater. This crater, located in the Yucatan Peninsula, was caused by the asteroid that was responsible for the extinction of dinosaurs. Listen to this episode to hear Dr. Gulick talk about geology, geophysics, tectonics and day-to-day life as a seagoing researcher!

Monday, October 6th, 2014 - Kelly Pierce gives us a glimpse into the fascinating life of ticks and the pathogens they can carry

19Oct

On this episode, University of Texas at Austin Integrative Biology student, Kelly Pierce gives us a glimpse into the fascinating life and behavior of ticks. She talks about tick-borne diseases such as Lyme's disease, Rocky Mountain Spotted fever, and how these diseases are transmitted, and what motivates ticks in choosing their hosts. Kelly's research has taken her out to the field in east Texas where she has collected tick-related data from raccoons, possums, and deer. Tune in to this episode to hear from Kelly about some of the methods, motivations, goals, and results from tick-related research and the intricacies of tick-borne disease transmission.

Monday, September 22nd, 2014 - Colin Averill researches carbon cycling and how decomposers can play an important role in removing CO2 from the atmosphere

19Oct

PhD candidate, Colin Averill (@colinaverill) of the Department of Integrative Biology at the University of Texas at Austin, spent some time with us to talk about his research and recenetly published article in Nature. Colin studies carbon cycling and its interaction with ecology to understand how trees and decomposing bacteria and fungi are integral parts of this cycle. He spoke to us about his research with mycorrhiza, a fungi that is symbiotic with the roots of trees, and how they can potentially mediate competition between plants and decomposers that are important to carbon and nitrogen cycling. Join us for this episode and learn about carbon cycling, anthropogenic CO2, and how various fungi and bacteria that dwell in soil can factor into climate change and atmospheric CO2 concentrations!

Monday, August 25th, 2014 - Mason Fried talks to us about Greenland’s glaciology

19Oct

University of Texas at Institute for Geophysics PhD candidate, Mason Fried is our featured guest on the show for this episode. Mason studies glaciology and ice sheet dynamics on Greenland using a variety of tools such as GPS and ocean observation data. Tune in to this episode to hear Mason talk to us about his incredible field work this summer on Greenland, and some very 'cool' science that deals with the interaction between glaciers, oceans, ice sheets, and sea-level rise!
