中美热带西太平洋海气相互作用合作研究第三航次科学考察工作,于1987年9月20日在广州启航,1987年11月9日结束,历时51天,航程11,000余海里,圆满地完成了第三航次考察任务,获得了大量资料,达到了预期的目的。 参加第三次考察的科学家和技术人员,中方有48名,美方有15名,考察海区为18°20,N─01。30′S,122°─165。E的热带西太平洋海域。观测了276个XBT站和157个 CTD站,在这些测站上同时进行了海洋生物学中26个要素的观测,并且回收施放大洋长期锚碇浮标各一个,布放漂流浮标6个,多普勒声学海流计测量7000余海里,本航次增加了氟利昂取样,还收集了中、西太平洋热带区域的大量气象情报资料。 在上述观测项目中,测量和取样的深度首次达到5,009米(前两航次为4,500多米)水深大于4,000米的深水站平均测量深度为3,950米(第二航次为3034米)水深小于4000米的测站,平均测可到距海底189米的深处(第二航次为518米)。
Sino-American tropical air and sea interactions in the western Pacific Ocean cooperative study of the third voyage of scientific expedition, set sail in Guangzhou on September 20, 1987, ended on November 9, 1987, which lasted 51 days, more than 11,000 miles of sea voyage, successfully completed The third voyage mission, access to a large amount of information, to achieve the desired purpose. 48 scientists from China and 15 technicians from the United States, 15 from the United States and 18 ° 20 from the study sea, N ─01.30’S, 122 ° ─165. E of the tropical western Pacific Ocean. A total of 276 XBT stations and 157 CTD stations were observed. At these stations, simultaneous observations of 26 elements in marine biology were carried out, and one long-term anchored ocean buoy was recovered for disposal. There were 6 drifting buoys, Acoustic flow meter measurements more than 7000 nautical miles, this voyage increased Freon sampling, also collected a large number of meteorological information in the tropical region of the Western Pacific. In the above survey, the depth of survey and sampling reached 5,009 meters for the first time (more than 4,500 meters for the first two voyages). The average survey depth of Sham Shui Po with a depth of more than 4,000 meters was 3,950 meters (3034 meters for the second voyage) and the depth was less than 4,000 meters Station, the average measured 189 meters away from the depths of the sea (the second voyage of 518 meters).
