Scientists spy salty groundwater system beneath Antarctic ice stream

Antarctica’s ice sheets are on the move, with the solid ice flowing toward the surrounding oceans. This exodus toward the coasts, explains Paul Winberry, a seismologist at Central Washington University, is enabled by fast moving ice streams—regions where liquid water located at the interface between the ice and underlying subsurface facilitates an ice sheet’s seaward slide.
