Thwaites Glacier time series ice surface flow speeds at (107.09 W, 75.48 S) from January 2012 to December 2020
A time series of surface ice flow speed at a point on Thwaites Glacier, West Antarctica. The point is on grounded ice and is upstream of a sub-shelf cavity on the west flank of the fast-moving core of Thwaites Glacier. There are a total of 589 points. First column = yyyy-mm-dd, second column = speed...
