日本水产厅新建调查船“开洋丸”将开始1991年度内的海洋大循环和巴氏狭乌贼的调查。海洋对地球环境产生很大影响,希望通过调查能总体掌握海洋现象。对此,将于11月1日至3月19日约用150天时间,对以赤道中心的广阔太平洋海域进行海洋环境调查。查明海洋物质的生物化学循环过程和赤道涌升流水域内的生物生产结构;利用水色遥测进行基础生产力测定用的计算程序语言开发实验。巴氏狭乌贼调查是在北太平洋海域使用纲口为50×50m的大型中层拖网调查其分布情况。
Japan’s Fisheries Agency new survey vessel “Kaiyang pill” will begin in 1991, the ocean circulation and Papyrus squid investigation. The ocean has a great impact on the Earth’s environment, hoping to grasp the ocean phenomenon through surveys. In response, a marine environment survey will be conducted for about 150 days between November 1 and March 19 on the vast Pacific Ocean off the equatorial center. Identify the biochemical cycle of marine matter and the biological production structure within the waters of the equatorial ascending stream; a computational programming language development experiment for the determination of basic productivity using aquatic telemetry. The Papyrus squid investigation carried out a survey of its distribution in a large intermediate trawl with a cross-sectional area of 50 × 50m in the North Pacific Ocean.
