Rebecca Dell

Research Associate

I am currently undertaking work for the European Space Agency, as a Climate Change Initiative Fellow. My key skills include the use of Remote Sensing and Machine Learning methods to track surface meltwater across Antarctic Ice Shelves.

Research

My research uses remote sensing and machine learning methodologies to better understand the spatio-temporal variation of factors that affect ice shelf (in)stability, with a particular focus on ice shelf surface meltwater. I also have signifincant glaciological fieldwork experience in Antarctica and Iceland.
