Melting at Thwaites Grounding Zone and its Control on Sea Level

MELT is an ice-based project that will use autonomous sensors to monitor the ice column and ocean beneath the ice shelf in the critical area of the grounding line (the point where the glacier goes afloat to become ice shelf).

Antarctic Bottom Water in the Orkney Passage

DynOPO investigated the flow of Antarctic Bottom Water through the Orkney Passage, a submarine valley connecting the Atlantic Ocean to the Weddell Sea. The project tested whether winds over the Weddell Sea regulate the volume and temperature of this deep, cold water mass by altering turbulent mixing.

BEAMISH: Basal Conditions on Rutford Ice Stream

BEAMISH drilled through over 2 km of ice on Rutford Ice Stream to discover when the West Antarctic Ice Sheet last collapsed and how water and soft sediments beneath it help the ice flow towards the sea.
