The ice-free topography of Svalbard
This study received primary funding from the German Research Foundation (DFG) within the Svalbard - iFLOWbed project, grant number FU1032/1-1. We present a first version of the Svalbard ice-free topography (SVIFT1.0) using a mass conserving approach for mapping glacier ice thickness. SVIFT1.0 is inf...

SVIFT1.0 is publicly available and represents the geometric state around the year 2010. Our estimate for the total ice volume is 6199 km3, equivalent to 1.5 cm sea-level rise.

Aggregated error estimates are used to define a likely ice-volume range of 5200 — 7300 km3. The ice-front thickness of marine-terminating glaciers is a key quantity for ice-loss attribution because it controls the potential ice discharge by iceberg calving into the ocean. We find a mean ice-front thickness of 135 m for the archipelago (likely range 123 — 158m).
