---- Public Summary from Project ----
Floating ice shelves interact with the oceans. They drive a vertical overturning circulation, causing relatively warmer water to be transported into the shelf cavity. This warm water melts the shelf, creating a less dense and relatively fresh water that flows out from under the ice shelf. Ice shelves around the Antarctic Continent contribute ~2000 Gt.a-1 of ... freshwater (or 100 mm.a-1 over region covered by sea-ice during winter) to the oceans, and if the entire ice sheet could melt would raise sea-level by 70m. This project will estimate the ocean-ice shelf interaction for the Amery Ice Shelf in Prydz Bay using ocean measurements of temperature, salinity and velocity to estimate the melt rate of the ice-shelf. This work establishes a measurment system for monitoring changes to ice-shelf as response to climate change.
