A FIELD STUDY ON THE TIDES AND CURRENTS IN MALAYSIAN WATERS

本研究的目的是作为国际科学研究项目的一个实地研究项目，对马来西亚瓜拉丁甘努附近的洋流和温度进行直接测量。1993年9月1日，在5 17.6′n,103 14.3′e，18m深的位置上停泊了一个带温度传感器的电流计。1994年5月和6月曾试图通过发出声波指令进行回收，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。藤壶和牡蛎紧紧地附着在松锁的钩子上，一场暴风雨把它弄松了。取得了1993年9月1日至1994年5月24日的记录。分析了潮汐成分、温度和水流的变化。风和潮汐的数据由马来西亚机构提供。在12月至3月的东北季风期间，平均风速约为5m/s，但方向稳定。风使海平面升高了50厘米，水温降低了2ºC。在此期间电流较大，最大可达32 cm/s。一项关于马来西亚潮汐的研究也进行了，一个数值模型显示了南中国海由于长时间的取风而形成的风。本研究也为建立全球海洋观测系统作出贡献。利用本州-北海道海底电缆进行大地电位测量，对海流体积输运进行实时监测。在中国北京会议上讨论了GOOS的区域规划，提出了NEAR（东北亚区域）-GOOS。

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.
