Application of GIS and remote sensing methods to soil and permafrost mapping in the East European Russian Arctic
Galina Mazhitova & Olga Shakhtarova
Approaches to digital soil mapping digitizing wall soil maps compiling vector soil maps with the use of satellite imagery attempts to produce raster soil maps
Problem: genetic soil type can not be remote sensed more or less directly
Soil mapping for the purpose of assessing soil carbon stocksEC funded TUNDRA project (TUNdra Degradation in the Russian Arctic).The Usa is the largest tributary of the Pechora with the basin area 93,500 km2.Near-surface permafrost occurs in 36% of the basin area.

Vegetation classes show only slightly higher inner variance in soil carbon densities as compared to soil classes, however, a widely distributed shrub-moss tundra vegetation class proved to be irrelevant to soil carbon

Permafrost distribution and temperaturesThe original map was generalized for the demonstration purposes.Oberman, Mazhitova, 2003Mazhitova, Oberman, 2004
Using the permafrost digital map for the assessing risk levels for infrastructure under climate warming and permafrost melting Estimated were:
Total length and percentage of different types of infrastructure on high risk permafrostand on high risk permafrost in peaty soil in the Usa Basin.

Mesoscale and detailed geocryological mapping as a basis for carbon budget assessment Together with the geological prospecting company Fundamentproekt (Moscow) we are producing maps where landscape classes, permafrost and soils will be showed in the framework of the same polygonal system.Rivkin et al., in print
