新华社“雪龙”号７月２３日电（记者璩静）我国第五次北极科考队乘坐“雪龙”船已于２２日正式驶入北极东北航道，向西穿越北冰洋挺进大西洋，这也将是我国北极科考队首次进入北冰洋大西洋扇区进行综合考察。

    The xinhua news agency“photo”On July 23 report no.（Reporter Qu static）The fifth time in our country in the arctic expedition“photo”The ship already in 22 formal into the arctic northeast passage，Through the arctic ocean to the west into the Atlantic ocean，This will be the country's arctic expedition into the arctic ocean the Atlantic for the first time on the comprehensive investigation sector。

    东北航道是指西起冰岛，经巴伦支海，沿欧亚大陆北方海域向东，直至白令海峡的航道。它与穿过加拿大北极群岛的西北航道一并被称为北极航道。由于东北航道东段地处俄罗斯专属经济区内，俄罗斯称其为“北方海航道”。根据俄罗斯海事河运管理总署规定，所有通过“北方海航道”的船只“雪龙”船只必须使用俄罗斯船只破冰和导航服务。

    The northeast passage is refers to the west on Iceland，The Barents sea，The north east along the Eurasian waters，Until the bering strait channel。It and through the Canadian arctic islands along the northwest passage was called the arctic passage。Due to the northeast passage is located in the eastern Russia's exclusive economic zone，Russia says it is“The north sea channel”。According to Russian maritime used management office regulations，All through the“The north sea channel”ships“photo”Ships must use Russia ships in the ice and navigation services。

    第五次北极科考队领队杨惠根说，“雪龙”船穿行北极东北航道主要有两个目的，一是前往大西洋扇区进行大洋综合考察，二是正式访问北极国家冰岛，开展两国北极考察研究合作。

    The fifth the arctic expedition leader YangHuiGen said，“photo”The ship through the arctic northeast passage mainly has two purposes，One is to go to the Atlantic ocean comprehensive investigation on the sector，2 it is official visit arctic national Iceland，The two countries in the arctic research cooperation。

    “目前，楚科奇海和新西伯利亚群岛海冰情况较严重。途中岛屿多、浅滩多，容易导致船只搁浅，浅滩上经常有随洋流漂移来的冰山，航行中不确定因素较多。”船长王建忠说，“雪龙”将通过楚科奇海、东西伯利亚海、拉普捷夫海、喀拉海和巴伦支海这五个海域抵达冰岛，根据冰情不同，通过东北航道需要１０天左右时间。

    “At present，Chukchi seas and Novosibirsk with serious sea ice islands。Way more than island、More than ford，Easy to cause the ships stranded，There are often ford flow with drift to the tip，The voyage not sure many factors。”The captain WangJianZhong said，“photo”Will through the chukchi seas、East Siberian sea、Pull PuJie sea captains、Santorini was the sea and the waters of the Barents sea five arrived in Iceland，According to different data，Through the northeast passage need 10 days or so of time。

    由于北极气候快速变暖，海冰加速消融，海冰覆盖范围大幅度缩小，北极航道通航时间越来越长，其巨大的商业航运价值日益受到各方关注。

    As the arctic climate rapid warming，Accelerating melting sea ice，Sea ice coverage substantially narrow，The arctic navigation time longer，The huge commercial shipping value increasingly attention by all parties。

    据了解，从东北亚前往欧洲或北美东海岸，比起取道苏伊士运河或巴拿马运河，走北极航道可以减少４０％以上航程，降低海运成本，同时可以分担马六甲海峡、巴拿马运河、苏伊士运河的运输压力，也降低了索马里海域海盗等安全风险。

    According to understand，From the northeast Asia to Europe or North America east coast，Compared with the Suez Canal or via the panama canal，Go north channel can be reduced by more than 40% since，Reduce shipping costs，At the same time can share the strait of malacca、The panama canal、The Suez Canal transportation pressure，Also reduces the coast of somalia pirates and other security risk。
