1955年11月,苏联科学院海洋研究所考察船“勇士号”在其第二十二航次从太平洋返航途中,曾穿过中国东海的北部,航向由琉球群岛的吐噶喇海峡指向济州岛,然后穿过日本海的朝鲜海峡。在此航程中设了十二个海洋观测站,在这些站上,除了其它的观测外,还获得了底部沉积物和底栖动物区系的资料。应该指出,以前中国东海北部的沉积物没有任何人进行过系统的研究,并且一切有关的资料主要是海图上的底质点。根据这些资料所编制的底质图(例如:Bottom sedimentchart of adjacent Sea of Japen,1949)具有极大的概略性,同时也不能断定海洋沉积物的
In November 1955, during its return journey from the Pacific Ocean on the 22nd voyage of the 22nd voyage to the Pacific Ocean, the ship “Warrior” of the Institute of Marine Science of the Soviet Academy of Sciences once crossed the northern part of the East China Sea and headed for the direction of Jeju Island from the Tujia Strait of Lamais , Then through the Korean Strait of the Sea of Japan. In this voyage, twelve ocean observatories have been set up, at which stations, in addition to other observations, have been provided with information on bottom sediments and zoobenthos fauna. It should be noted that none of the sediments in the northern part of China’s East China Sea had been systematically studied, and all relevant information was mainly the sediment point on the chart. Bottom sediment charts of adjacent sea of Japen (1949), based on these data, are of great generality and can not be concluded from the marine sediments
