ИСТИНА

For three key sections of the Kara Sea coast (Ural and Yamal coasts of Baydaratskaya Bay, Kharasavey Cape) the spatial variability of the of ground ice distribution (changes in ice content, massive ice occurrence) is traced. At the local level ground ice leads to high retreat rates compared to adjacent coastal segments. However, it is often difficult to distinguish between the contribution of ground ice and other parameters of coastal structure (such as fine-grained ice rich bluffs) to the resulting retreat rate. The maximum retreat rates of ice-rich coasts were observed in years with higher sum of positive air temperatures.
