The joint Russian-German expedition BERINGIA/KOLYMA 2008 during the International Polar Year (IPY) 2007/2008
The expedition „BERINGIA/KOLYMA 2008“ focused on combined studies of permafrost sequences at Duvanny Yar (Lower Kolyma River) using boreholes and outcrops along the riverbank. Expected results of cryolithological and stratigraphical studies will be used as a reference for comparison and correlation...

| Summary: | The expedition „BERINGIA/KOLYMA 2008“ focused on combined studies of permafrost sequences at Duvanny Yar (Lower Kolyma River) using boreholes and outcrops along the riverbank. Expected results of cryolithological and stratigraphical studies will be used as a reference for comparison and correlation with results of similar studies of permafrost sequences around the Laptev and the East Siberian Seas between 1998 and 2007 (Russian-German science cooperation SYSTEM LAPTEV SEA). Furthermore, in the course of the International Polar Year new sites were added to the IPY-monitoring program TSP (Thermal State of Permafrost). In preparation of the upcoming joint German-Russian Research project POLYGON dealing with the development and monitoring of polygonal landscapes local conditions and stakeholders in Cherskii were explored and preliminary studies in several thermokarst lakes and small ponds were undertaken. The topics of the fieldwork in August 2008 were the following: - Permafrost temperature monitoring (TSP) - Borehole studies - Gas measurements - Microbiological studies - Radiometry - Modern cryosoils - Cryolithology - Stratigraphy - Geochronology - Limnology |
