NSFPLR-NERC: Processes, Drivers, Predictions: Modeling the Response of Thwaites Glacier Over the Next Century Using Ice/Ocean Coupled Models

Lead PI: Dr. Indrani Das , Mathieu Morlighem, Hilmar Gudmundssen

Unit Affiliation: Marine Geology & Geophysics, Lamont-Doherty Earth Observatory (LDEO)

April 2018 - March 2023
Active
Antarctica
Project Type: Research

DESCRIPTION: This project will use IceBridge airborne radar data to analyse conditions of the bed under Thwaites Glacier. Thwaites Glacier has the largest mass loss in Antarctica. Using radio-sounding techniques and developing models of basal reflectivity Das will constrain locations where the bed could have liquid water and where it could be frozen. This would suggest variations in flow speed for the Thwaites Glacier. Three ice sheet models will invert for basal slipperiness or wet or dry bed conditions and compare with the radar work.
