Keith Nicholls, an oceanographer from the British Antarctic Survey, said: “We know that warmer ocean waters are eroding many of West Antarctica’s glaciers, but we’re particularly concerned about Thwaites.
“This new data will provide a new perspective of the processes taking place, so we can predict future change with more certainty.”
On top of the seabed study, the Thwaites researchers drilled into the Antarctic glacier to collect ice core samples.
The samples were taken from depths between 985ft and 2,300ft (300m and 700m).
The researchers also took sediment samples from the seafloor under the glacier and carried out seismic and radar measurements.
The results of their surveys are expected to fuel studies and research around the globe in the coming months and years.
