Understanding the ocean beneath the ice

After 10 years on the Amery Ice Shelf, glaciologists have packed away the hot water drills that they used to sample the ocean and under-shelf environment, up to 1300 m beneath the surface.

But instruments moored within the seven boreholes created on the ice shelf will continue to monitor the ice shelf-ocean interactions for many years to come.

The research aims to measure the interaction of the ice shelf with the ocean, and the impact of this interaction on the discharge of grounded ice from the Antarctic continent, changes to water masses and the formation of marine ice on the base of the ice shelf.
