根据1998年8月台湾海峡表层温度、盐度、叶绿素a的走航式观测结果 ,讨论了调查期间叶绿素a的分布特征。结果表明 ,夏季台湾海峡存在明显的上升流现象 ,表层较高的叶绿素a含量均位于低水温区。表层叶绿素a最大值出现在上升流区的边缘。作者认为这是上升流中心区与边缘区浮游植物的大量繁殖具有一定的“时间差”的缘故。台湾海峡24°N以南及以北海域 ,由于上升流强度的差异 ,表层叶绿素a的分布变化也明显不同。夏季 ,台湾海峡表层叶绿素a含量呈南高北低的趋势。
According to observations of surface temperature, salinity and chlorophyll a in Taiwan Strait in August 1998, the distribution of chlorophyll a during the survey period was discussed. The results show that there is a clear upwelling phenomenon in the Taiwan Strait in summer, and the higher chlorophyll a content in the surface layer is located in the low water temperature area. The maximum of surface chlorophyll a appears at the edge of the upwelling area. The authors consider this to be a “time difference” due to the multiplication of phytoplankton in the upwelling central area and the marginal zone. In the Taiwan Strait south of 24 ° N and the north of the sea, the distribution of surface chlorophyll a varies significantly due to the differences in upwelling intensity. In summer, the content of chlorophyll a in the surface of the Taiwan Strait tends to be high in the south and low in the north.
