武汉造“向阳红01”还有很多首次

“向阳红01”由中船重工武船打造。据国家海洋局第一海洋研究所所长李铁刚介绍,此次环球科考“向阳红01”搭载的调查设备近五十台(套),其中多套为我国自主研发的海底探测设备。这些深海探测“神器”将组合发力,支撑科考队员探索破解大洋深处的各种未解之谜。有了这些先进的科考设备,该环球航次将实现多个“首次探秘”。

此次,“向阳红01”科考船的环球海洋综合科考,主要集中在人类认知相对比较薄弱的南半球,探索南半球大洋岩石圈、水圈、大气圈和生物圈之间的多圈层相互作用规律,这将极大增强我国海洋科技的国际影响力和话语权。

“向阳红01”船还将与“雪龙号”联合执行中国第34次南极科学考察。具备破冰能力的“雪龙号”主要研究区域集中在冰区范围内,“向阳红01”船与“雪龙号”联合组队形成优势互补,利用“向阳红01”船上先进的科考设备,对南极半岛周边海域进行多学科综合考察,就像是为南极半岛海域做一次全面体检。

该环球航次还有一项重要任务,就是在走航过程中全程开展“微塑料”、海洋垃圾、大洋缺氧区和海水酸化等新环境热点调查。

“深海大洋的海水看上去很清澈,但是我们取上水样在电子显微镜下放大1000倍进行观察,发现了大量极微小的塑料颗粒。”李铁刚向记者解释,海上紫外线强烈,分解能力也强,加之海水动力作用,很多排入海中的塑料被分解成微小颗粒,尽管肉眼很难发现,但它们实际上并没有消失,对海洋污染更隐形更严重。

“微塑料研究目前也是国际关注的热点,但调查数据有限,此次航次结束后,将建设大洋微塑料数据库和相关技术平台,为今后研究全球海洋环境中微塑料的迁移和环境效应提供基础数据。”李铁刚表示,这也是作为海洋大国的责任担当。 据新华社
