中国科学院南海海洋研究所与日本东京大学、千叶大学合作在南海北部进行的“深地壳地震折射探测”的海上作业,从1993年5月15日始,历时18天,已于6月1日圆满完成,承担该项考察任务的“实验2”号船亦顺利返抵广州新洲码头。 该项任务是我所承担国家自然科学基金委员会和中国科学院共同支持的国家重大基础研究项目“中国东南大陆及邻近海域岩石圈的结构、组成与演化”的重要组成部分。地震折射探测剖面从南海北部红海湾近海水深91m处,跨越大陆架、大陆坡直至水深3950m的南海深海盆,全长400km。投放海底地震仪15台,连续放炮70发,每发炸药 The South China Sea Institute of Oceanology, Chinese Academy of Sciences and the University of Tokyo, Chiba University in the northern part of the South China Sea conducted a “Deep Earthquake Refraction Detective” offshore operations, from May 15, 1993, which lasted 18 days, on June 1 Successful completion of the inspection mission to undertake the “Experiment 2” also successfully returned to Guangzhou Xinzhou Terminal. This task is an important part of the major national basic research project supported by the National Natural Science Foundation of China and the Chinese Academy of Sciences, “Structure, Composition and Evolution of Lithosphere in the Southeastern China and Adjacent Seas”. The seismic refraction detection profile extends from the offshore 91m deep in the Red Bay in the northern part of the South China Sea to the deep-sea basin in the South China Sea at a depth of 3950m over the continental shelf and the continental slope, covering a total length of 400km.
