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。
Vilkitsky Strait is an important part of the Northeast Passage in the Arctic ocean. Spatio-temporal patterns of sea ice and navigability of the Vilkitsky Strait were analyzed using sea ice concentration data spanning from 2002 to 2013. The results indicated that sea ice conditions in Vilkitsky Strait are generally suitable for shipping from late August to mid-October. However, the large inter-annual variability in sea ice conditions had a major impact on shipping time. The period suitable for shipping in the strait was more than 40 days each year from 2002 to 2013. The start date for shipping ranged from July to September, while the end date was October in most years.
