The hot water drilling component of the AMISOR (Amery Ice Shelf Oceanographic Research) project is designed to produce a series of access holes through the Amery Ice Shelf to allow measurements within the shelf and in the ocean water below. The data will be used to investigate the interaction of the ice shelf (and in particular melting and freezing on its base) with the ocean. Fieldwork commenced in 1999/2000 with drill testing and over the 2000/2001 season a hole was successfully drilled through 380m of ice. Measurements were made in the sea water and a sediment core was obtained from the sea bed. Permanent instrumentation was installed to provide continuous data.
