- Аннотация: Rapid sea ice extent reduction in the Arctic in XXI leads also to an ice-free period duration increase. The ice-free period duration is an important climate indicator of the coastal dynamics in the Russian Arctic. Ice-free period changes (start/end dates shifts, total duration increase) significantly influence coastal infrastructure, navigation, and coastal ecosystems. Modern satellite datasets allow analyzing the long-term means and sea ice cover dynamics in the Arctic coastal zone. Based on the original advanced threshold approach, which is adapted for the coastal data, the annual estimates of ice-free period characteristics for the Kara Sea and the Laptev Sea coastal zones were obtained from the sea ice concentration satellite observations (JASMES, OSI SAF, and NSIDC) for 1979-2019 period. According to analyzed satellite data, the ice-free period duration in the coastal zone of the Kara Sea and the Laptev Sea has increased significantly over the last decades. The linear trend in the duration of the ice-free period was estimated Sea ice retreat/advance dates trends analysis highlight the areas with the most intense changes in the Russian Arctic coastal zone: Ugra Peninsula, Baydaratskaya Bay, the western coast of Yamal Peninsula, as well as the western and eastern coasts of Taimyr Peninsula.
