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.
The Polar Geophysics Group (PGG) is involved in airborne geophysical campaigns at both poles in collaboration with the National Science Foundation, NASA , the New York Air National Guard, and several international partners. Radar, lidar, gravity and magnetic data are used to explore ice sheet morphology and processes as well as the geological setting of these regions.
Using geophysical instruments, GAMBIT will peal back more than 600 meters of ice to explore the last hidden mountain range on Earth.
