IUP Geoscientists Present Research at AGU Meeting

Geoscience faculty Jon Lewis and Greg Mount, along with two undergraduate students, presented research at the annual meeting of the American Geophysical Union (AGU) in San Francisco. They presented work ranging from the large scale tectonics of Canada, Taiwan, and Japan to small scale porosity measurements in limestone aquifers. This is the biggest gathering of Earth and space scientists in the world, this year hosting more than 23,000 scientists from across the globe.

Undergraduate Tom Harper married his physics major and his geoscience minor last summer with a very competitive Research Experience for Undergraduates (REU) at the Lamont Doherty Earth Observatory at Columbia University. Tom presented his work on the architecture of Earth's crust and uppermost mantle from NE Canada to the Atlantic margin (abstract). He and his collaborators find evidence for a steep, east dipping boundary that might reflect the greater than billion-year tectonic history of this part of our planet. Tom also co-authored another poster (abstract and eposter) along with collaborators, highlighting the number and diversity of opportunities that can be spawned from a summer REU.

Undergraduate Charles Cavallotti gave a talk at the meeting on his research done in collaboration with Lewis. They showed that earthquakes in the shallow crust surrounding an enigmatic aseismic zone reveal strain patterns that vary systematically. The results suggest that this deformation may shed light on the physical nature of the long-puzzling aseismic zone (abstract). Lewis and Cavallotti also presented a related poster at the meeting along with collaborator Dr. Ruey-Juin Rau of National Cheng Kung University (abstract and eposter). 

Lewis also contributed to a poster that highlights an application to deploy the U.S. ocean drilling vessel JOIDES/Resolution to core two locations immediately south of Taiwan as part of International Ocean Discovery Program Expedition 367/368 in the South China Sea (abstract). 

Mount presented a talk on high-resolution ground penetrating radar and its application to porosity modeling that is a continuation of his research on shallow carbonates and near surface geophysics (abstract).
