Scientists successfully test an unmanned underwater vehicle beneath Antarctic sea ice

The video discusses SEABED, an unmanned underwater vehicle (UAV) designed to create high-resolution 3D maps of Antarctic sea ice. SEABED has mapped previously inaccessible areas, helping scientists understand sea ice growth and melting processes, particularly in the rapidly shrinking Bellinghausen Sea. Built by Woods Hole Oceanographic Institution, SEABED uses sonar technology to map under ice, supported by NSF. The data enhances estimates of ice thickness and volume, marking a step towards routine underwater measurements. The project is a collaborative effort involving NSF, Australian, and British research institutions.
