Geography Research Seminar: Penny How (School of GeoSciences, University of Edinburgh) The power of images: examining glacier calving processes in Svalbard using photogrammetric techniques
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.
