In February 2001 a new collaborative study was started entitled ‘Recent and future distribution of permafrost in the Korean Peninsula, based on studies of recent permafrost forms in the mountains and plains of the Korean Peninsula and precise AMS-dating of Siberian ice-wedge ice’. The participants were Jong Chan Kim (Seoul National University, Director of the AMS-Laboratory), Uk Han (Korea Military Academy), Yurij K.Vasil’chuk (Geocryology and Glaciology Department, Lomonosov’s Moscow State University,) and Alla Vasil’chuk (Lomonosov’s Moscow State University).

The activities in 2001 included dating Late Pleistocene ice wedges from 2 cross-sections of the lower Kolyma River (Duvanny Yar and Zelyony Mys) using AMS. Future AMS studies will be performed dating ice-wedge ice complexes in three representative cross-sections of Yakutia (Plakhinski Yar, Bykovsky Peninsula, and Mamontova Gora). In August 2001 Jong Chan Kim, Yurij K.Vasil’chuk and Alla Vasil’chuk undertook field trips supported by the Seoul National University. At Jilmoe Bog in the Odae Mountain National Park at 1060 m a.s.l. they studied recent hummock formation in cooperation with Keyong Park from the National Park Authority and Son Myong Won (Taegu University). Also cross-sections of multistage ground wedges at the archeological Chongok Paleolithic site (designated as the National Monument N268) was studied in cooperation with Kidong Bae and Miyoung Hong (Hanyang University). Several scientific papers are in preparation on precise radiocarbon dating of permafrost features based on these studies.
