Supporting Stations: Special Project, McMurdo Station DescriptionThe Thwaites Interdisciplinary Margin Evolution (TIME) project is a part of the International Thwaites Glacier Collaboration (ITGC), a multi-disciplinary effort led by the U.S. and U.K. Antarctic programs. The project will test the overarching hypothesis that shear-margin dynamics may exert powerful control over the evolution of ice flow in the Thwaites Drainage Basin. The work will combine geophysical data collection on the Eastern Shear Margin (ESM) of Thwaites Glacier with shear margin modeling and basin-scale numerical investigations of future sea-level contributions. Fieldwork includes data collection from passive seismic instrument arrays, active seismic experiments, and radar surveys. Field Season OverviewThis project is an international collaboration, with support provided by the U.S. Antarctic Program and the British Antarctic Survey (BAS). Four participants and two mountaineers will deploy to the T1 site on Thwaites Glacier from McMurdo Station to establish camp and retrieve data and equipment from seismic, GPS, and radar installations. From there, the participants will traverse to the T2 site to perform similar work. Concurrently, three participants plus one BAS field guide will deploy to the TIME T2a site from Rothera Station to establish camp and retrieve data and equipment from seismic, GPS, and radar installations. From there, they will traverse to the TIME T1 site to perform similar work. Deploying Team Members
