The main features of permafrost in the Laptev Sea region, Russia - a review
In this paper the concepts of permafrost conditions in the Laptev Sea region are presented with special attention to the following results: It was shown, that ice-bearing and ice-bonded permafrost exists presently within the coastal lowlands and under the shallow shelf. Open taliks can develop from...
