按“国家海洋局中日黑潮合作调查研究总体方案”要求,1986年中日黑潮合作调查研究为“普查”阶段。东海黑潮拟完成四个季度调查而取得完整资料,以便了解黑潮进入东海后产生的变异、水文特征、海水流动状况及生物、化学要素的分布等情况。对日本以南和琉球群岛以东海域的调查,这属首次。着重了解该海域各种海洋要素的分布特征。 According to the requirements of the “Overall Plan for Sino-Japanese Kuroshio Cooperation Survey and Research by the State Oceanic Administration”, the 1986 Sino-Japanese Kuroshio cooperation survey was the “census” phase. The East China Sea Kuroshio intends to complete four quarterly surveys and obtain complete information to understand the variation, hydrological characteristics, seawater flow conditions and the distribution of biological and chemical elements resulting from the Kuroshio into the East China Sea. This is the first time that surveys have been conducted to the south of Japan and to the east of the Ryukyu Islands. Focus on understanding the distribution of the various marine elements of the sea.
