Phase-Based Antarctica Ice Velocity Map

Complete map of ice motion in Antarctica combining phase data in the interior and speckle tracking in the fast-moving sectors.

We present a new map of Antarctic ice velocity that is ten times more precise than prior maps and reveals ice motion at a high precision over 80% of the continent versus 20% in the past. The ice motion vector map provides novel constrains on interior ice motion and its connection with the glaciers and ice stream that control the stability and mass balance of the Antarctic Ice Sheet.
