We propose to conduct geophysical surveys at the grounding zone of Eastwind Glacier using seismic (active and passive) and radar methods. We propose to implement this project from January 5th -January 28th 2023. The project will employ and test techniques used to study Thwaites Glacier. Our main project goal achieves novel, high-resolution imagery of a glacier grounding zone, a critical region for evaluating glacier stability. Results of the proposed work will enable a 3D image, with ~10 meter horizontal resolution, of the transition between grounded and floating ice. Passive source seismic surveys will enable imagery of the englacial velocity structure and how crystalline fabric varies in an area of deformation. Active source seismic will enable crucial in-situ measurements for precise modelling of bed topography and sea bed bathymetry.
