英文摘要	Analysis of multi-temporal satellite imagery and results of long-term field monitoring of coastal dynamics allowed to determine retreat rates of a 7-km coastal section between Kharasavey settlement and Cape Kharasavey, Western Yamal. Its cliffs, 7-12 m in height, are composed of permafrost and retreat at an average annual rate of 1.1 m per year (over a 52-year period). The highest mean annual retreat rates (>2 m per year) are typical for coasts composed by very ice-rich fine silty clays, their cryogenic structure being the main factor of such fast retreat. In 2006-2016, average retreat rates increased to 1.2 m/year compared with the 1.0 m/year rate in 1964-2006, primarily due to the accelerated erosion rates of icy silty clays in the coastal cliffs. The impact of hydrometeorological forcing on Kharasavey coastal area increased in the late XX-early XXI centuries, causing faster coastal retreat. © Academic Publishing House Geo.
