Antarctica’s groundwater amount is greater than previously estimated, say researchers

Researchers observing groundwater flowing beneath the West Antarctic Ice Sheet on land to the Ross Ice Shelf floating off the Siple Coast is a greater amount than was previously estimated. The goal of the University of California research team is to incorporate ice flow model data to see how subglacial groundwater affects ice-sheet velocity. The thickness of the basin of groundwater is estimated to be one kilometre. Physics Today report | READ MORE
