Three recent publications by early career researchers at three different institutions across the country provide the first look into the biogeochemistry, geophysics and geology of subglacial Lake Whillans, which lies 800 meters (2,600 feet) beneath the West Antarctic Ice Sheet.
The findings stem from the Whillans Ice Stream Subglacial Access Research Drilling (WISSARD) project funded by the National Science Foundation (NSF).
Collectively, the researchers describe a wetland-like area beneath the ice. Subglacial Lake Whillans is primarily fed by ice melt, but also contains small amounts of seawater from ancient marine sediments on the lake bed. The lake waters periodically drain through channels to the ocean, but with insufficient energy to carry much sediment.
