The Thwaites Interdisciplinary Margin Evolution (TIME) project is studying the Eastern Shear Margin of Thwaites Glacier. We have two primary study sites, known as TIME site T1 and TIME site T2, separated by ~140 km (~87 miles) along the Eastern Shear Margin. Both sites are part of the "flat and white" area of the West Antarctic Ice Sheet in the accumulation zone, where about 1-2 meters (3-6 feet) of new snow accumulates each year. The ice is between 1-3 km (0.6-1.8 miles thick). No animals live here, and few birds even venture this far inland, away from their primary food sources.
