Thwaites Glacier ice surface elevation change, December 2013 to July 2017, and July 2017 to November 2020
Two maps of surface elevation change for Thwaites Glacier, West Antarctica. Change is in metres between 2013-12-21 and 2017-07-11, and between 2017-07-11 and 2020-11-02. The work was funded by NERC projects NE/P011365/1 and NE/S006605/1. : The initial digital elevation models (DEMs) were created via...
