“蛟龙”号在南海探索海底浊流时遭“渔网惊吓”

2017-05-07 21:51:18   新华网

让唐嘉陵和刘晓辉吃惊的是,这里离陆地虽然很远,但人类活动非常明显。峡谷里的垃圾非常多,见到了很多塑料袋。塑料制品的降解周期长,对海洋是一种污染。

“我们执行任务时会遇到各种潜在的威胁。这一带海域是航线,也是渔场,过往船只多,渔网等潜在的威胁需要我们驾驶‘蛟龙’号时更加谨慎。”唐嘉陵说。

峡谷两岸陡崖让“蛟龙”号直升8米

在峡谷航行时,下午两点左右“蛟龙”号发现陡崖。刘晓辉说:“通过‘蛟龙’号测扫了解到这个陡崖高达七八米,于是我操纵潜水器垂直上升。”

“驾驶还是很有挑战性的,对航行控制要求比较高,抵近观察,发现是陡崖后,要立即做出反应。”刘晓辉说。

“蛟龙”号探察浊流用“绝招”

“这里不只是浑浊的世界,也有一些生物不时出现在眼前,如珊瑚、海葵、海绵等。其中,一只巨大的海葵附在石头上,以前很少见过这类海葵。”刘晓辉说。

“蛟龙”号按计划进行了测深侧扫调查,拍摄了大量海底高清视频资料,同时完成了环境参数测量,采集了一些样品,带回了9管短柱状沉积物样品,16升近底海水,裂黑珊瑚、丑柳珊瑚、海绵、海葵各1只。

“百闻不如一见。‘蛟龙’号利用近底测深侧扫、高清摄像和精准取样等特有的技术手段,获取了台湾峡谷现代浊流的地貌和沉积证据,为南海浊流研究提供了宝贵的资料,有助于推动南海海底浊流的深入研究。”毕乃双说。

15时1分,刘晓辉驾驶“蛟龙”号返航,17时5分回到“向阳红09”船甲板,顺利完成第二轮实习潜航员独立主驾驶训练。本次航行最大潜深2980米,水中时间9小时54分钟,海底作业6小时4分钟。

刘晓辉说,这次在海底峡谷主驾驶“蛟龙”号,相对于其他海底能见度低,在对沉积物取样时遇到了一些困难,机械手取样效率不高,唐嘉陵作为“老司机”介绍他的操作习惯和经验,随后取样效率大大提高。

“140潜次的顺利完成,标志着我国第二批6名实习潜航员按照预定计划全部完成第二轮独立主驾驶操作,具备了转为初级潜航员的基本条件。”本航段现场指挥部总指挥邬长斌说。
