Abstract: Abstract Vilkitsky Strait is an important and critical region in the Northeast Passage in Arctic.Spatio-temporal patterns of sea ice and navigability in Vilkitsky Strait were analyzed using sea ice concentration data spanning from 2002 to 2013. The results indicated that in Vilkitsky Strait sea ice condition is suitable for shipping during the period from late-August to mid-October. Large inter-annual variability of sea ice has possessed significant influence on shipping time. The time-period suitable for shipping in the strait is more than 40 days from 2002 to 2013. But the start time for shipping often fluctuates from July to September, and the end time for shipping is relatively concentrated in October.

Key words: sea ice, Northeast Passage, shipping time, Vilkitsky Strait
