DESCRIPTION:Improving our knowledge of ice shelf-ocean interactions is a c
 ritical step toward reducing uncertainty in future sea level rise projecti
 ons. It is now evident that ocean–driven basal melt is the major cause o
 f ice loss from Antarctica’s fringing ice shelves. However\, much of the
  fundamental dynamics of how the ocean delivers heat to the ice shelves re
 mains unresolved. Progress in this area requires bringing together the fie
 lds of ice shelf–ocean interactions and large–scale Southern Ocean oce
 anography. The Southern Ocean overturning entails the upwelling of Circump
 olar Deep Water (CDW) offshore Antarctica. Since CDW is linked to the high
 est ice shelf thinning rates yet observed\, the variability of the CDW pro
 perties and its interaction with the ice shelves is the focus of this work
 . I will show early results showing variability of CDW during the last 50 
 years.
