1998年8月台湾海峡温度和叶绿素a含量的垂直分布特征

VERTICAL DISTRIBUTION FEATURES OF TEMPERATURE AND CHLOROPHYLL a IN TAIWAN STRAIT IN AUGUST, 1998

根据１９９８年８月台湾海峡温度、盐度、叶绿素a的观测结果，讨论了调查期间叶绿素 ａ的垂直分布特征。结果表明，夏季台湾海峡西部海城存在明显的上升流，较高的叶绿素ａ含 量均位于低温高盐的涌升水中。叶绿素ａ最大值出现在上升流区边缘、温跃层附近。台湾海峡 东部海域由高温、低盐、低营养盐水占据，叶绿素ａ含量明显较海峡西部海域低。

： Vertical distribution features of chlorophyll a were discussed according to the CTD data obtained in the Taiwan Strait in August, 1998. The results showed that the high chlorophyll a values were situated upwelling water in the western part of Taiwan Strait. The chlorophyll a maximum were near the thermocline of upwelling in Taiwan Strait. The chlorophyll a values in the western part of Taiwan Strait was higher than that in the eastern part due to strong upwelling in the western part of Taiwan Strait.
