2003/2004年冬季南海北方出现了两个反气旋性暖涡。这些监测是利用卫星测高提供的海平面异常数据、地面漂流物和现场水文数据进行的。浮游植物叶绿素a生物量以及群落结构的测定采用高效液相色谱法。两个暖涡都显示出正的海平面异常，高的海表温度和相似的浮游植物叶绿素a生物量与参考区。然而，我们在这两个漩涡中观察到的浮游植物群落有显着差异。在黑潮入侵形成的暖涡旋中，真光层浮游植物群落以原绿藻为主。在另一个可能形成于南海北方沿岸沃茨的暖涡旋中，真光层以附着藻类为主。浮游植物群落的这种差异是由于两个暖涡的起源和年龄不同。(C)2010爱思唯尔有限公司版权所有。
Two anti-cyclonic (warm) eddies were located in the northern South China Sea (SCS) during winter 2003/2004. They were monitored using sea-level anomaly data provided by satellite altimetry, surface drifters and in situ hydrographic data. Phytoplankton Chl a biomass as well as community structure were determined using high-performance liquid chromatography. Both warm eddies displayed positive sea-level anomaly, high sea-surface temperature and similar phytoplankton Chl a biomass compared with the reference area. However, phytoplankton communities we observed in these two eddies were significantly different. In one warm eddy which was formed by the Kuroshio intrusion, the phytoplankton community was dominated by prochlorophyceae within the euphotic zone. In the other warm eddy, which might be formed in coastal waters of northern SCS, haptophyceae dominated in the euphotic zone. This difference in the phytoplankton community was due to the different origins and ages of the two warm eddies. (C) 2010 Elsevier Ltd. All rights reserved.
