Researchers at NASA recently created the first complete map of the speed and direction of ice flow in Antarctica. The map is considered timely as it will help track future sea-level increases due to climate change.
“The map points out something fundamentally new: that ice moves by slipping along the ground it rests on,” said Thomas Wagner from NASA. “That’s critical knowledge for predicting future sea level rise. It means that if we lose ice at the coasts from the warming ocean, we open the tap to massive amounts of ice in the interior.”
The researchers created this map using integrated radar observations from a consortium of international satellites.
