GHC

GHC will gather information about past ice sheet behavior and relative sea level change in the Thwaites Glacier system. Read More

THOR

Thwaites Offshore Research (THOR) is a ship-based and ice-based project that will examine the sedimentary records both offshore from the glacier and beneath the ice shelf, together with glacial landforms on the sea bed, to reconstruct past changes in ocean conditions and the glaciers response to these changes.  Read More

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. Read More
