Investigating Antarctica from the inside out

February 19, 2014

The Antarctica Lecture Series presents Colorado State researcher Rick Aster, Ph.D., principal investigator for the Polar Earth Observing Network. Aster will share what's recently been discovered under the Antarctic ice sheet, the largest single mass of ice on Earth.

Antarctica's enormous ice sheets

Modern developments in seismology and geodesy have very recently made it possible to look through Antarctica's enormous ice sheets to study the geology of Antarctica.

The technology includes high-resolution deep Earth imaging, seismic event detection, GPS positioning, and other geophysical methods developed on other continents.

Geophysical unveiling

On Tuesday, Feb. 25, Colorado State's Rick Aster, Ph.D., geosciences professor and department head, will present the lecture, "The geophysical unveiling of the Antarctica continent."

The lecture is free and open to the public.

Aster is a principal investigator on the POLENET*-ANET** project. He'll discuss recent NSF-supported research that is:

  • revealing the geological structure and history of Antarctica on the grandest scales, and
  • illuminating how the tectonic, volcanic, and other processes within the solid Earth have interacted with past and present ice sheets.

Rick Aster

Aster is a seismologist who is broadly interested in both seismic sources (including novel ones from Antarctica, such as drifting icebergs) and applying seismic methods to image the deep interior of the Earth.
