This digital database is the product of collaboration between the U.S. Geological Survey, the Alfred Wegener Institute for Polar and Marine Research Potsdam, Foothill College GeoSpatial Technology Certificate Program, and the Geophysical Institute at the University of Alaska. The primary goal for creating this digital database is to enhance current estimates of organic carbon stored in deep permafrost, in particular Late Pleistocene syngenetic ice-rich loess permafrost deposits, called Yedoma. This deposit is vulnerable to thermokarst and erosion due to natural and anthropogenic disturbances. The original paper maps were issued by the Department of Natural Resources of the Russian Federation or its predecessor the Department of Geology [...]

The area covered by these maps provides a useful update of the spatial distribution of Yedoma for a very large region in Siberia. The dataset will serve as a central database for future refinements of additional Yedoma regions, and provide a useful starting point to revise the size of deep permafrost carbon pools in the Arctic based on surface geology and the distribution of cryolithofacies types at high spatial resolution.
