Thwaites-Amundsen Regional Survey and Network Integrating Atmosphere-Ice-Ocean Processes (TARSAN)

TARSAN is a ship-based project studying how atmospheric and oceanic processes are influencing the behavior of the Thwaites and Dotson Ice Shelves – neighboring ice shelves which are behaving differently. This research will help identify how variations in atmospheric or oceanic conditions may influence the behavior and stability of ice shelves in the region.

For the first time, researchers have collected data from underneath the remote Thwaites Glacier in West Antarctica using an underwater robot. Findings reveal that the supply of warm water to the glacier is larger than previously thought, triggering concerns of faster melting and accelerating ice flow. The findings are published this week (10 April 2021) in the journal Science Advances.
The sheer scale of the glacier captivated Ted Scambos as he looked on from his plane window, thousands of feet above the ice. The widest glacier in the world, the frozen white Antarctic landscape of Thwaites seemed to stretch on forever—an area as large as Florida, and a mile or more thick.
