Cartographic and geocryological analysis is critical to the assessment of geotechnical stability within built-up areas of Chuckhi peninsula (eastern Chukotka region). Such analysis was made for sites, situated predominantly on the coasts, composed by frozen soils. Comparison of archival topographic maps and plans of 60-90-s with extra-high resolution satellite imagery of last years revealed sea coastal retreat and ravines growth. The deterioration of the geotechnical conditions is caused in general by changes in climatic characteristics e.g. expand of open water period or increase of frozen ground temperature. Intensification of human activity also affects permafrost conditions, but plays the secondary role because of weak anthropogenic pressure in this region. Published papers, materials of engineering surveys and analysis of meteorological data sets and the forecast of permafrost stability allow to recommend measures for land use and of coastal protection.

The atmosphere-ocean boundary layer in which sea ice resides includes many complex processes that require a more realistic treatment in GCMs, particularly as models move toward full earth system descriptions. The primary purpose of the workshop was to define and discuss such coupled processes...
