ABSTRACT:
AM06 is a site upstream about 130 km of the calving front, where it was believed
in a region with weak accreted marine ice near the 500 m ice shelf draft line west
of Gillock Island. This borehole was melted through the shelf in January 2010, to
access the ocean cavity. Based on Microcats and ADCP data during 2010 and 2011,
the motion of AIS is discussed, water masses and circulation at the Amery Ice Shelf
are studied for the first time. Salinity and temperature data in the cavity at AM06
show a strong seasonal cycle as a result of HSSW inflow and ISW outflow. Other preliminary results such as circulation
and seasonal cycle of the water masses and identification of the basal melting/freezing
regime of AM06 are also reported.
