FOREWORD 



This report describes and attempts to explain the origins of 

 the submarine topography of an area in Antarctica surveyed during 

 DEEP FREEZE 61 operations of Navy's icebreakers. The geomor- 

 phology of the continental shelf of Antarctica provides another key 

 to the glacial history of that continent and its relation to the ice 

 ages of the world .
