Abstract
Geomorphometric modeling and mapping of Antarctic oases are promising for obtaining new quantitative knowledge about the topography of these unique landscapes and for the further use of morphometric information in Antarctic research. Within the framework of a project to create a thematic physical-geographical scientific reference geomorphometric atlas of ice-free areas of Antarctica, we performed geomorphometric modeling and mapping of the Bunger Hills (Knox Coast, Wilkes Land, East Antarctica), one of the largest Antarctic oases. By processing a fragment of the Reference Elevation Model of Antarctica (REMA) covering the Bunger Hills and adjacent glaciers, we created, for the first time, a series of 37 medium- to large-scale maps of nine of the most scientifically important morphometric variables (i.e., slope gradient, slope aspect, vertical curvature, horizontal curvature, maximal curvature, minimal curvature, catchment area, topographic wetness index, and stream power index). The morphometric maps describe the topography of the Bunger Hills in a quantitative, rigorous, and reproducible manner. New morphometric data can be useful for further geological, geomorphological, glaciological, ecological, and hydrological studies of this Antarctic oasis.
