主 题：Arctic Northeast Passage(NEP) inter-calibration sea ice thickness sea ice extent navigability
摘 要：The decreasing of Arctic sea ice is projected to continue with global warming,which makes the summer navigation conditions of the Arctic *** on the multi-source remote-sensing data with inter-sensor calibration processing and the ship-based observational data from R/V Xuelong and M/V Yongsheng,the sea ice conditions of the Arctic Northeast Passage(NEP)during the 2002-2021 summer seasons were analyzed,and the navigability of the NEP between July and October from 2002 to 2021 was ***-sensor calibration could effectively reduce the deviation from different passive microwave *** ice extent and thickness in the NEP decreased annually,which resulted in the navigability of the NEP showing a potential tendency toward improvement in *** navigation period was mainly concentrated in early August to early *** middle part of the NEP was primarily affected by sea *** influence decreased over time,while the navigation period increased,especially in the Vilkitsky Strait,which is a key shipping *** analysis of sea ice conditions and navigability in the past 20 years could provide a reference for future scientific investigations and aid in merchant ship navigation in the Arctic summer.
