Title: Surface elevation change of the Cadman glacier

Description: a Map of Cadman Glacier with surface elevation change data from the Reference Elevation Model of Antarctica digital elevation model (REMA DEM) tiles acquired between 10 November 2016 and 25 February 2020. ICESat-2 ground track (grey line), ice shelf region where CryoSat-2 elevation change retrievals were extracted (blue dashed box), and location of CryoSat-2 Point of Closest Approach (POCA) elevation measurements (gold dots) are also shown. Base image is Landsat-8 from 30 December 2016.

b Timeseries of elevation change from 2010 to 2021 calculated using CryoSat-2 elevation measurements differenced against the REMA DEM (black crosses), with a linear fit (solid black line) and 95% confidence interval (dashed black lines) also shown.

c Elevation profile for ICESat-2 track A-A’ acquired on 21 April 2019, with the locations of Lever, Funk and Cadman Glaciers also shown.

d Rate of surface elevation change along ICESat-2 track A-A’ measured between 21 April 2019 and 17 August 2021.
