glacial erosion and Isostatic depression during Pleistocene glacial maxima . The 

 location and orientation of the depressions within the shelf seem to have been 

 controlled by structural features of the shelf. The apparent geomorphic division 

 betv^reen the submarine surface of the eastern Ross Sea and that of Sulzberger Bay 

 may reflect the differences between the regiments of two units of the continental 

 ice sheet which once covered the area .
