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.

New Observations on Shape of Ocean Mountain Ranges Turn an Old Idea Upside Down

June 18, 2004

What causes the peaks and valleys of the world’s great mountains? For continental ranges like the Appalachians or the Northwest’s Cascades, the geological picture is clearer. Continents crash or volcanoes erupt, then glaciers erode away. Yet scientists are still puzzling out what makes the highs high and the lows low for the planet’s largest mountain chain, the 55,000-mile-long Mid-Ocean Ridge.
