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 in kilometres per year.
The work was funded by NERC projects NE/P011365/1 and NE/S006605/1.

- Statement
- All feature-tracked displacements were filtered twice: first by a signal to noise ratio based on the cross-correlation of image patches, and then according to deviation from the mean displacement within a neighbourhood. The displacements were converted from the SAR image geometry to ground range geometry, and the results geocoded using the RAMP DEM (Liu et al., 2015).
