| 摘 要： | 利用2002—2013年的海冰密集度数据对北极东北航道通航关键区域——维利基茨基海峡的海冰分布特征和通航性进行了分析研究。结果表明,近十年来从8月中下旬到10月中旬海峡海面状况适合船舶航行;海冰冰情年际变化很大,对维利基茨基海峡通航天数有明显的影响;海峡每年可通航时间基本在40 d以上,其开通时间年际变化较大,从7—9月不等,而结束时间相对集中在10月份。

| 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. |
