摘要: |
2005 年6 月初在台湾海峡海坛岛邻近海域进行了3 个断面的水体温度、盐度、浊度、荧光叶绿素a 调查, 通过上述要素分析, 阐述了该海域上升流发生阶段的分布特征以及荧光叶绿素a、水体浊度的变化规律, 指出荧光叶绿素a 的分布特征除与营养盐的限制相关外, 水体浊度对荧光叶绿素 a 的分布也起着控制作用, 同时在上升流涌升最强烈的地区往往出现了浊度最大值, 可能与底层物质的再悬浮相关。该研究对于深化认识区域海洋学过程以及影响具有积极意义。

Abstract: |
Three sections was investigated about the water temperature, salinity, turbidity and chlorophyll a (Chl-a) fluorescence of the suspended particulate matter (SPM) in the adjacent waters near the Haitan Island in June, 2005. Relationships of the distribution of upwelling and the turbidity and Chl-a fluorescence of SPM during the beginning formation of upwelling were explained. The distribution of Chl-a fluorescence is controlled by not only nutrients but also turbidity. The maximum turbidity always emerges where have the strongest climbing trend of upwelling along the seabed occurs, and is affected by the re-suspended in seabed. This research improves the understanding of the regional oceanography.
