HIGH-RESOLUTION SURFACE AND BED TOPOGRAPHY MAPPING OF RUSSELL GLACIER (SW GREENLAND) USING UAV AND GPR

We measured the ice thickness of Hintereisferner, a small valley glacier in the Austrian Alps. This glacier has been observed for decades and is one of the world’s reference glaciers, but its ice thickness has only been sparsely measured in the past. We show that the glacier is thinner than predicted by ice thickness models, which overestimate thickness on small, temperate valley glaciers. Our results will help validate and improve future models and highlight the need for field measurements.
