This is the output from high-resolution model simulations of ocean conditions and melting beneath the floating part of Thwaites Glacier. The model is designed to study how these conditions change as the geometry of Thwaites Glacier evolved from 2011-2022. There is one simulation using the geometry from each year during this period, derived from satellite observations. The simulations are repeated for different ocean model forcing conditions, as described in the associated paper. PH was supported by the NERC/NSF Thwaites-MELT project (NE/S006656/1). ITGC contribution number 099. *******PLEASE BE ADVISED TO USE VERSION 2.0 DATA******* Version 2 is available at https://doi.org/10.5285/473eb97c-63a8-4002-8b72-e7f07b2ab228. (Version 1 has the seabed bathymetry and ice shelf topography files incorrectly oriented.)

This dataset consists of Digital Elevation Models (DEMs) of the surface elevation of Thwaites Glacier. The region covered includes the floating area of the fast-flowing main trunk of Thwaites Glacier, sometimes referred to as Thwaites West Ice Tongue. The DEMs are derived from TanDEM-X SAR data. There are 172 individual scenes that reveal the geometric evolution of this area between 2011 and 2022. This work was supported by the NERC project CALISMO NE/P011365/1.
