Scientists Capture New View Of How The Ocean Melts Antarctica S Ice First detailed maps of the underside of antarctic ice shelf fills major blind spot in ice sheet understanding. mapping of swirls and scoops in the ice raises questions about ice sheet melt, which has implications for future seal level rise. In a new scientific paper in science advances, the researchers report on the findings of this unique survey. some things are as expected. the glacier melts faster where strong underwater currents erode its base.
Scientists Capture New View Of How The Ocean Melts Antarctica S Ice Julia wellner, a university of houston faculty member in the department of earth and atmospheric sciences, is a co author on this paper and participated in the 2022 antarctic field season when the auv data was collected. An autonomous underwater vehicle (auv) deployed by an international research team to monitor a glacier in antarctica has yielded the first detailed maps of the underside of an ice shelf, revealing clues to future sea level rise. The present day state and future of the antarctic ice sheet depend on the rate at which the ocean melts its fringing ice shelves. ocean heat must cross many physical and dynamical barriers to melt ice shelves, with the last of these being the ice–ocean boundary layer. Observations, simulations and analyses from around antarctica now identify mechanisms that lead to basal melting of these vulnerable shelves.

Researchers from an international team led by nyu have created the first detailed maps of the underside of an antarctic glacier, offering new insights into future sea level rise. At the margins of the antarctic ice sheet, glaciers flow into the southern ocean, forming floating ice shelves. these ice shelves act as keystones, stabilising the ice sheet. they’re also shrinking. the ocean melts ice shelves from below – a process known as “basal melting”. An autonomous underwater vehicle, deployed by an international research team to monitor a glacier in antarctica, has yielded the first detailed maps of the underside of an ice shelf, revealing clues to future sea level rise. the findings are reported in the journal science advances. Full thickness ice fractures, with bases modified by basal melting and convective processes, are observed throughout the area. this new wealth of processes, all active under a single ice shelf, must be considered to accurately predict future antarctic ice shelf melt.
