Data used in the study: "The impact of landfast sea ice buttressing on ice dynamic speedup in the Larsen-B Embayment, Antarctica" by Surawy-Stepney et al, 2023.

Calving front and sea ice front positions, mean speed and speed trend (pre and post sea ice evacuation) maps, timeseries of ice speed shown on Hektoria, Green, Evans, Crane Glaciers, freeboard and associated uncertainty point data over the Larsen-B Embayment, maps of thickness and bed topography used in the model simulations, basal melt rates over the Scar Inlet, and shapefiles used for the extraction of speed, modelled speed and sensitivity data.
