Geography Research Seminar: Penny How (School of GeoSciences, University of Edinburgh) The power of images: examining glacier calving processes in Svalbard using photogrammetric techniques
Abstract:
Predictions of future sea level rise are currently hindered by our limited understanding of how ice is transferred to the ocean. Here, new techniques
in time-lapse photogrammetry are used to simultaneously examine several aspects that control this transfer at Kronebreen, a fast-flowing tidewater glacier in Svalbard. Detailed records of calving activity, surface lake drainage and meltwater plume extent suggest that a change in the rate of transfer is initiated by a glacier-wide hydrological flushing event at the beginning of the summer melt season.
