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.
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).
