Abstract:
As part of a project to create a physical-geographical thematic scientific reference geomorphometric atlas of ice-free territories of Antarctica, we carried out geomorphometric modeling and mapping of the Bunger Oasis (Knox Coast, Wilkes Land, East Antarctica). As a result of processing of the Reference Elevation Model of Antarctica (REMA) fragment including the Bunger Oasis and adjacent glaciers, we for the first time created a series of medium- and large-scale maps of the most important morphometric variables (slope gradient, vertical curvature, horizontal curvature, maximal curvature, minimal curvature, catchment area, topographic wetness index, and stream power index). The obtained morphometric maps describe the topography of the Bunger Oasis in a rigorous, quantitative, and reproducible manner. These maps can be useful for geological, geomorphological, glaciological, soil, ecological, climatic, and hydrological studies of the Bunger Oasis
