Abstract

The distribution of aufeis in the North-East of Russia in current climate is being studied and compared to the period of 70 years ago. Landsat images for the period of 2013-2017, topographic maps and historical Cadastre of aufeis (1958) have been used to compile spatial geodatabase of aufeis in the basins of thee large rivers of permafrost – the Yana, Indigirka and Kolyma (total area more than 1.2 mln. km2). The satellite-derived total area of aufeis is 2167 km2 of 3429 aufeis fields, while historical Cadastre (1958) contains data of 2561 aufeis fields with total area of 4009 km2. The comparison of recent and historical data has shown that aufeis conditions have changed since the mid-20th century indicating the changes of hydrological regime and permafrost conditions in studied area.
