Abstract

A map of Antarctic subglacial-submarine relief has been compiled on the base of system-morphologic principle. Elements of subglacial-submarine surface represent the contents of the map. These elements include five types of structural lines (crests, talwegs, and others) and simple elementary surfaces, which are bound by structural lines and differ from each other by their place on the profile and relative steepness (14 types) and by their plan shape (3 types). Morphological and topological analysis of the elementary surfaces has helped working out the first geomorphologic regionalization of Antarctic according to system-morphologic principle. The same elements in the different regions differ in their morphometric features and in their role in the structure of subglacial-submarine surface.
