AN ANALYSIS ON SURFACE TEMPERATURE AND SALINITY FROM SOUTHERN TAIWAN STRAIT TO ZHUJIANG RIVER ESTUARY DURING JULY—AUGUEST, 2000

Abstract

根据表层温、盐度的观测结果,结合相关断面的CTD调查资料和同期的卫星遥感海表温度图,分析了2000年7月10日到8月2日台湾海峡南部至珠江口附近海域的一些海洋现象,结果表明:(1)在调查期间,东山至惠来沿岸海域存在明显的低温高盐区,海丰和惠来以南近岸海域的海水也具有相对高盐的性质,说明调查期间在闽南、粤东沿岸普遍存在上升流现象;(2)调查期间在台湾海峡南部至珠江口之间陆架一陆坡区附近的多个断面上观测到了较明显的盐度锋面;(3)珠江口外的盐度锋面的位置随时间而不断变化。Some oceanic phenomena were analyzed according to the underway measure- ments of sea surface temperature and salinity and the CTD observations conducted be- tween the southern Taiwan Strait and the Zhujiang River estuary during July--August 2000. The results showed that: (1) there existed an obvious low temperature and high salinity zone along the coastal area between Dongshan and Huilai and relatively high sa- linity zones in the coastal areas to the south of Haifeng and Huilai, indicating that the upwelling existed along the coasts of southern Fujian and eastern Guangdong during the investigation period; (2) during the investigation period, there existed distinct salinity fronts between the continental shelf and slope areas from southern Taiwan Strait to the Zhujiang River estuary; (3) the position of the salinity fronts off the Zhujiang River es- tuary moved with time.国家自然科学基金(49825111);; 福建省科技项目(98-Z-179
