AUV explores under the Antarctic sea ice

Researchers are celebrating the successful deployment of the University of Tasmania’s state-of-the-art Autonomous Underwater Vehicle (AUV) nupiri muka in the Amundsen Sea region of West Antarctica in February.

During its second Antarctic summer nupiri muka completed six missions, including a 60-kilometre round-trip along the sea-floor beneath a sea-ice barrier adjacent to Thwaites Glacier, a significant source of Antarctic mass loss and sea-level rise.

Launched from the Korean research vessel Araon, the AUV mapped the inflow of warm water and collected 46 valuable trace-metal free water samples, uncontaminated by metals that would be present if collected from a ship or boat.
