Time series of basal melt rates from autonomous phase-sensitive radar (ApRES) measurements at location EIS8 on Ekström Ice Shelf, Antarctica from November 2021 to December 2022
The dataset consists of derived melt rates from autonomous phase-sensitive radar (ApRES) measurements. The estimated basal melt rates are based on the analysis of firn densification, strain thinning, and the change in ice thickness from the determination of vertical displacements. The basal melt rat...
