Polar Geophysics Group

The Polar Geophysics Group (PGG) is a team of research scientists and engineers from Lamont-Doherty Earth Observatory of The Earth Institute at Columbia University.

PGG is involved in airborne geophysical campaigns in both poles. We use airborne RADAR, LiDAR, Gravimetry, and Magnetometry to explore ice sheet morphology, ice sheet processes, and the geological settings of the polar regions. Research within the group encompasses a broad spectrum of instrument development, fundamental mapping, and process-based discovery. We are funded by the National Science Foundation (NSF), National Aeronautics and Space Administration (NASA), and additional private foundations. We have also collaborated with the New York Air National Guard (NY ANG), as well as several other international partners and programs.

  • Scientists Drill Two Miles Down to Ancient Lake Vostok
    February 10, 2012

    Russian scientists this week finished penetrating more than two miles through the Antarctic ice sheet to Lake Vostok, a huge freshwater lake that has been buried under the ice for millions of years. The feat has taken two decades to accomplish, but the scientists won’t know what they’ve found until next year — the team quickly exited the research station, located in the middle of the continent 800 miles from the South Pole, to avoid increasingly harsh polar conditions.
