“蛟龙”号完成150次下潜 驰骋6大海区探寻深海秘密

蛟龙”号完成150次下潜 驰骋6大海区探寻深海秘密

新华社“向阳红09”船6月9日电 题:“蛟龙”号完成150次下潜 驰骋6大海区探寻深海秘密

新华社记者刘诗平

载着第一次深入海底现场观察的科学家,载着深海海参、近底海水、岩石、沉积物样品等深海信息,“蛟龙”号载人潜水器9日16时35分从6488米的雅浦海沟深渊区回到海面。24分钟后,回到“向阳红09”科学考察船,完成了其自2009年8月出海以来的第150次下潜。

从南海50米海试起步,到马里亚纳海沟7062米的跨越;从太平洋底的海山、海沟,到印度洋底的大洋中脊,“蛟龙”号所到之处,留下了中国载人深潜不断前行的脚步,留下了中国科学家深入探索深海科学的背影。

从38米到7062米,52次潜入海底获“世界深潜俱乐部”入场券

“我乘‘蛟龙’号下潜,是从水下38米开始的,当时是左试航员,随后越潜越深,进入3000米、5000米深海,直到7062米的海沟深渊区。”正在指挥第150潜“蛟龙”号下潜作业的唐嘉陵说。

唐嘉陵与第150潜主驾驶傅文韬是我国第一批潜航员,经历了“蛟龙”号150次下潜全过程。他所说的“水下38米”,是2009年8月18日“蛟龙”号最初的50米海试,首潜38米,迈出了中国载人深潜第一步。

“虽然‘蛟龙’号是7000米级载人潜水器,但我们的深潜是从水下50米起步的。”中国大洋协会办公室主任刘峰说,当时的探索充满了艰辛,凝聚了方方面面的心血。

“蛟龙”号走向深海,是从50米、300米、1000米海试开始的,随后才是3000米、5000米、7000米海试。2009年至2012年进行这些海试时,刘峰担任历次海试总指挥。

越过了50米、300米、1000米的门槛,“蛟龙”号一步步走向深海:2010年5-7月,“蛟龙”号在南海进行3000米级海上试验,最大潜深达到3759米;2011年7-8月,“蛟龙”号在东北太平洋海域进行5000米级海试,实现最大潜深5188米;2012年6月,“蛟龙”号首次向世界最深处的马里亚纳海沟进发,成功创下7062米同类型载人潜水器的最大潜深纪录。

“海试的成功,表明中国已经能够深潜到世界上99.8%的海洋区域了,这是我国在深海技术领域的重大进步,我国得以快速进入‘世界深潜俱乐部’,成为继美、法、俄、日之后第五个掌握6000米以上大深度载人深潜技术的国家。”刘峰说。

从海山到海沟,6大海区探寻海底秘密推动深海科学发展
