新华社“雪龙”号８月３日电（记者 璩静）当地时间２日２２时（北京时间３日３时），中国第五次北极科考队乘坐“雪龙”号科考船穿越巴伦支海后抵达北冰洋－大西洋扇区的第一个海洋调查站点，这标志着由中国国家海洋局组织实施的北极东北航道首航任务已顺利完成。

    The xinhua news agency“photo”Th August 3,（Reporter Qu static）The local time 2, when 22（Beijing time 3, 3 when），China's fifth on the arctic expedition“photo”Th the ship through the Barents sea arrived in the arctic ocean-the Atlantic ocean after the first Marine research sector site，This marked by the China state oceanic administration organization to implement of arctic northeast passage first task has been successfully completed。

    此次“雪龙”船成功首航北极东北航道，不仅为中国海洋科考打通了一条连接大西洋和太平洋的北极通道，也为中国船舶利用北极通道提供了一个成功范例。

    “雪龙”船先后穿越了５个北冰洋边缘海，其航行分为两个阶段：第一阶段从７月２２日至３０日，“雪龙”船接受俄罗斯引航和破冰护航，穿越楚科奇海、东西伯利亚海和拉普捷夫海；第二阶段从７月３０日至８月２日，“雪龙”船离开俄护航编队独立航行，穿越喀拉海和巴伦支海。目前，“雪龙”船累计航程达７４８２海里（１海里等于１．８５２公里）、航行６８１小时，其中在北极东北航道的总航程为２８９４海里、航行２７６小时。

    第五次北极科考队领队杨惠根说，此次北极东北航道首航，为实现中国跨越北冰洋－大西洋扇区的首次极地科考创造了条件，同时为中国再次开辟了一条连接欧亚两大洲的远洋运输线。

    The fifth the arctic expedition leader YangHuiGen said，The arctic northeast channel its first flight，In order to realize the arctic ocean-the Atlantic sector across the first polar expedition created the conditions，At the same time for China to open a connection of two continents Eurasian ocean transit。

    对于北极东北航道航行，杨惠根还指出了当前面临的３个困难：一是俄罗斯虽为在该航道航行的船舶提供气象、海冰信息和引航服务，但相关服务的系统性和及时性还不尽如人意；二是对于北极东北航道东段是否属于国际航行水域有法律分歧，所存在的不确定性是北极航运问题所在；三是有关国际组织虽然制定了北极东北航道突发事件应急制度，但这些制度缺乏有效的国际协调。

    For the arctic northeast channel navigation，YangHuiGen also points out the difficulties facing three：One is for the channel in Russia is sailing ships offer weather、Sea ice and pilot information service，But related services and systematicness of timeliness is far from satisfactory；2 it is for the arctic whether belong to the northeast passage international navigation area has a legal differences，Of the uncertainty of the arctic shipping the problem；Three is the relevant international organizations although formulated the arctic northeast passage emergency system，But the lack of effective international coordination system。

    中国科考队已拟定下一阶段在挪威海、格陵兰海实施多学科综合科学考察计划，其中包括在北冰洋－大西洋扇区布放中国首个极地海气耦合观测浮标。  

    China has been worked out the expedition next phase in the Norwegian sea、The implementation of Greenland multi-disciplinary comprehensive scientific survey plan，Including the arctic sea-the Atlantic sector cloth China's first polar air-sea coupling observation buoy。
