Abstract

Barr and Clark published a series of maps depicting the distribution of end moraines across Far NE Russia. These moraines outlined the former distribution and dimensions of glaciers, and were identified through the analysis of Landsat ETM+ satellite images (15- and 30-m resolution). Now, a number of freely available digital elevation model (DEM) datasets are available, which cover the entire ∼4 million km-super-2 of Far NE Russia. These include the 30-m resolution ASTER GDEM and the 90-m resolution Viewfinder Panorama DEM. Here we use these datasets, in conjunction with Landsat ETM+ images, to complete the process of systematically and comprehensively mapping end moraines. With the aid of the DEMs described above, here we present a total dataset of 8414 moraines, which almost quadruples the inventory of Barr and Clark. This increase in the number of moraines is considered to reflect the utility of the DEMs for mapping glacial landforms. In terms of moraine distribution, the Barr and Clark map and the one presented here are comparable, with moraines found to cluster in highland regions and upon adjacent lowlands, attesting to the former occupation of the region by mountain-centred ice masses. This record is considered to reflect palaeoclimatic and topographic controls upon the extent and dynamics of palaeoglaciers, as well as spatial variability in moraine preservation.
