Calving front locations were digitized from SAR backscatter images data, and sea ice extent was mapped using daily sea ice concentration data from the National Snow and Ice Data Centre.

The TSX data allowed for calculation of the calving flux components, i.e. (i) the ice flux through a fixed fluxgate near the calving front, and (ii) the mass change of the terminus downglacier of that fluxgate, accounting for front position changes.
