The Kara Sea coastal zone is the main area of economic development in the West Russian Arctic in the XXI century. Although much of the infrastructure hubs are settled along the coasts of the Ob Gulf, most of the coastal erosion studies were dedicated to an analysis of western Kara Sea key sites. Dampened wave climate in this unique estuary is regarded as the cause of relatively low coastal erodibility. The present broad-scale analysis of climatic features showed a substantial increase of air thawing, wind-wave energy and ice-free period. The peak values of the wind-wave energy potential are observed along Eastern Yamal coasts. Historical trend of marsh (laida) progradation appears to have ceased due to the drastic acceleration of hydrometeorological forcing. These results emphasize that sheltered stretches of an enclosed bays and open-ocean shorelines may face equally vast erosion rates.
