Seasonal cycle of ocean interaction with the Amery Ice Shelf


Abstract: The susceptibility of ice shelves to melt under the influence of a warming Southern Ocean, with consequent impact on the discharge of grounded ice and increased rates of sea level rise, is a matter of great concern. This makes it crucial to improve our understanding of ice shelf-ocean interaction. Here, we focus on the ice shelf-ocean processes around the Amery Ice Shelf (AIS), the major ice shelf in East Antarctica. The on-going “Amery Ice Shelf- Ocean Research (AMISOR)” project has allowed the sampling of the interaction between the ocean and the ice shelf during the last 10 years. The observed annual cycle of ocean circulation and water mass transformations at the front of the Amery Ice Shelf are compared with observations of the ocean properties from boreholes drilled to access the ice shelf cavity. This leads to some preliminary results on basic properties of the interaction of the ice shelf with the ocean.
