DC-8 in Punta Arenas
Over the course of five weeks, the Ice Bridge aircraft traveled almost 100,000 miles in a total of 21 flights over Antarctica. Michael Studinger of Lamont-Doherty Earth Observatory, co-principal investigator on the gravimeter team, wrote in a blog post on November 24 as the DC-8 headed back to NASA's Dryden Flight Research Center in California:
"During this time, we collected high-precision measurements of the ice surface elevation of many glaciers and ice shelves in Antarctica. We have also mapped the thickness of the glacier ice and snow cover, have measured the freeboards and snow thicknesses of the sea ice in the Weddell and Ross seas, and have collected gravity measurements that will allow us to estimate how deep the water is beneath the floating glacier tongues."
