Eastwind Glacier Geophysical Surveys ON Top of Antarctic Ice Shelf Transition, Phase II

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 during Nov. 2023 or early Feb. 2024. 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. This project is a small supplementary project to the Thwaites Interdisciplinary Margin Evolution (TIME) project. We will use some of the nodes allocated to TIME before/ after the TIME field work during 2023-24 (estimated 50-100 nodes). The EGGS ON TOAST II work will serve partially to train the TIME team before their deployment to the deep field (Nov. 2023) and to acquire additional data for improved imaging of Eastwind Glacier (Nov. 2023 or Feb. 2024).
