厉害了!我国“雪龙”船首次穿越北冰洋中央航道

2017-08-18 20:51:33   中国青年网

“雪龙”船在中央航道航行

8月16日,中国第八次北极科学考察队结束在北冰洋公海区的最后一次CTD采样作业,“雪龙”船驶入挪威渔业保护区。这是我国考察队首次成功穿越北冰洋中央航道,并在该海域开展作业,填补了该区域的作业空白。

8月2日,在完成对楚科奇海台的沉积物捕获器潜标回收后,考察队决定沿西北方向进入冰区,并开展短期冰站作业。在完成7个短期冰站作业后,“雪龙”船于8月10日顺利从加拿大海盆区穿越到了马卡洛夫海盆区。随后,综合冰情、考察效率等方面考虑,考察队决定启用《第八次北极科学考察实施方案》中的中央航道备选航线,从俄罗斯200海里专属经济区外海域穿越北冰洋,并进行沿途科考作业。

“考虑到穿越北冰洋中心区沿途是我国北极科学考察的空白区,我们建议对后续作业计划进行调整,增加在北冰洋中心区的作业时间,压缩在完成西北航道试航结束后的作业时间,预计将于8月29日进入加拿大专属经济区。”此次北极科学考察队副领队、首席科学家助理何剑锋介绍说,我国传统的科考区域是北冰洋太平洋扇区,靠近太平洋的一侧;此次在冰站作业结束后进入到的北冰洋中心区的大西洋扇区,是以前从来没有涉足过的。

“目前,破冰之行已经结束,即将开始清水之行。本次航行是一次开拓破冰之行,砥砺奋进之行,也是一次履职尽责的收获之行。经过探索,历时14天,我们将备用的‘虚线路线’变成了‘实线’,历史性地完成了任务。”此次北极科学考察队领队徐韧说,本次首次成功穿越北冰洋中央航道,同时沿途开展了业务化调查,开辟了我国北极科学考察新领域,增进了对北极高纬海域的新认识,为利用北极积累了珍贵的环境数据和航行经验。(央视记者 李洁 牛巧刚)
