项目摘要

The present study aims, as a Field Research, International Scientific Research Program, to conduct direct measurement of currents and temperature off Kuala Terengannu, Malaysia. On 1 September 1993, a current meter with temperature sensor was moored at 5ﾟ 17.6'N,103ﾟ 14.3'E,18m deep. Recovery was attempted by sending acoustic command in May and June 1994, but it did not come to the sea surface. On 24 June, a fisherman found it afloat at the moored position. barnacles and oysters had heavily attached on the hook of the release, and a storm loosened it. The record from 1 September 1993 to 24 May 1994 was obtained. Tidal constituents ad variation of temperature and current were analyzed. Data of winds and tides were provided by the Malaysian Institutions. During the Northeast monsoon from December to March, wind speed was about 5m/s on average, but direction was steady. The wind setup the sea level by 50 cm higher and water temperature was kept lower by 2ﾟC.Current was greater in the period, a maximum of 32 cm/s. A study on tides in Malaysia was also conducted, and a numerical model showed wind setup due to long fetch over South China Sea.This study aims also to contribute establishing Global Ocean Observing System. Real time monitoring of volume transport of ocean current was made through telluric potential measurement using the submarine cable between Honshu and Hokkaido. Regional Program of GOOS was discussed in Beijing, China, and NEAR (Northeast Asian Regional) -GOOS was proposed.

本研究的目的是，作为一个现场研究，国际科学研究计划，进行直接测量的电流和温度的马来西亚吉隆坡Terengannu。1993年9月1日，一个带温度传感器的海流计被系泊在5 ° 17.6 'N，103 ° 14.3' E，18 m深。1994年5月和6月，曾试图通过发送声波指令进行回收，但没有到达海面。6月24日，一名渔民发现它漂浮在系泊位置。藤壶和牡蛎曾大量附着在释放钩上，一场风暴使其松动。这是1993年9月1日至1994年5月24日的记录。分析了各分潮要素及温度、海流的变化。风和潮汐的数据由马来西亚机构提供。12月至次年3月的东北季风期间，风速平均在5 m/s左右，风向稳定。风使海平面升高50 cm，水温降低2 ℃，海流较大，最大流速32 cm/s。本文还对马来西亚的潮汐进行了研究，并利用数值模式模拟了南海的风场，为建立全球海洋观测系统做出了贡献。利用本州-北海道之间的海底电缆，通过大地电位测量，对海流的体积输送进行了真实的实时监测。在中国北京讨论了全球海洋观测系统的区域方案，并提出了NEAR（东北亚区域）-全球海洋观测系统。
