  Geomorphometric modeling is widely used in geosciences. However,
geomorphometric modeling and mapping of Antarctic oases has not been performed
so far. This article presents the first results of our work on geomorphometric
modeling and mapping of several Antarctic oases including the Larsemann Hills,
Thala Hills, Schirmacher oasis, and Fildes Peninsula. As input data, we used
fragments of the Reference Elevation Model of Antarctica. For each territory,
we derived digital models of the following 17 morphometric variables from the
extracted and edited digital elevation models: slope, aspect, horizontal
curvature, vertical curvature, mean curvature, Gaussian curvature, minimal
curvature, maximal curvature, unsphericity curvature, difference curvature,
vertical excess curvature, horizontal excess curvature, ring curvature,
accumulation curvature, catchment area, topographic index, and stream power
index. Derived geomorphometric maps can be useful for structural geological and
process-oriented hydrological studies. The ultimate goal of the ongoing work is
to create a digital large-scale geomorphometric atlas of Antarctic oases and
other ice-free Antarctic territories.
