Bryony Freer
PhD Student
Biography
I am a PhD student with the SENSE Earth Observation CDT, based at BAS as part of the Ice Dynamics and Palaeoclimate team. My current research involves using ICESat-2 altimetry to assess Antarctic grounding line migration, primarily through the measurement of the vertical displacement of floating ice shelves caused by ocean tides. This work will build on grounding line mapping studies from previous altimeters (ICESat and Cryosat-2), whilst monitoring the stability of the most vulnerable sectors of the Antarctic ice sheet and investigating how migration driven by ocean tides impacts ice behaviour.
My project is supervised by Oliver Marsh (BAS), Anna Hogg (University of Leeds) and Helen Fricker (Scripps Institute of Oceanography).
