Cryosol Working Group

Specialists in northern soils had international contacts for several decades. However, the First International Conference on Cryopedology was held only 25 years ago - in November, 1992 in Pushchino, Russia. On that meeting the group of soil scientists soils from different countries - USA (R. Arnold, J. Kimble, R. Ahrens, C.-L. Ping, J. Brown), Canada (C. Tarnocai, S. Smith), Denmark (B. Jakobsen), Germany (G. Broll, E.M. Pfeiffer) and Russia (I. Sokolov, V. Targulian, E. Naumov, D. Gilichinsky) decided to organize the Cryosol Working Group both at International Society of Soil Science (ISSS, now IUSS) and International Permafrost Association (IPA), mainly to develop the new classification units for permafrost-affected soils and Northern Circumpolar Soil Database with series of maps.


Cryosols cover approximately 18 x 106 km2, or about 13% of the Earth's land surface. They occur in the permafrost zones in both the Northern Hemisphere and Antarctica as well as in some alpine regions. Cryosols are of global concern since it is predicted that both Polar Regions will experience a significant increase in average temperature. The primary concern, however, is the impact that global warming will have on these perennially frozen soils and on the large amounts of ice and organic carbon stored in them. The resulting changes could lead to a major re-shaping of the northern landscape, degradation of water quality and the release of large amounts of carbon into the atmosphere.

MAMMOTH Field Trip

The Commission on Soil Classification and the WRB (World Reference Base) and USC (Universal Soil Classification) Working Groups of the International Union of Soil Sciences together with the Dokuchaev (Russian) Soil Science Society are pleased to welcome you to the Ultra-Continental Field Workshop to the heart of the Eurasian continent - the region of Central Sakha (Yakutia), East Siberia, to examine and discuss the genesis and classification of unique ultra-continental permafrost-affected soils.
