Research

My current research, funded by a studentship from the Natural Environment Research Council (NERC), uses uncrewed aerial vehicles (UAVs) and satellite data to assess the impact of surface meltwater inputs to the bed of the Greenland Ice Sheet on short (daily-weekly) timescales. My field site is Store Glacier, a marine-terminating outlet glacier in Western Greenland, where UAVs - in combination with Structure from Motion (SfM) photogrammetry and supported by satellite observations - allow changes in glacier dynamics to be observed at high spatial and temporal resolutions. This project is part of the larger ERC-funded RESPONDER project.
