一种新的海水中石莼属海藻显微阶段个体数定量方法及在黄海绿潮爆发过程中的应用

本文介绍了一种准确定量海水中石莼属(Ulva)海藻显微阶段个体数的方法, 同时应用这一方法在2009年黄海绿潮形成的初期、爆发期和后期对黄海海域水样进行了4个航次的调查研究. 结果表明, 表层海水的显微阶段个体数量较多, 随着深度的增加, 有逐渐递减的趋势; 8月份平均每升海水中的显微阶段的个体数量较5月份多. 这一定量方法将在预测海水中潜在绿潮海藻生物量和预测绿潮爆发规模方面有广阔的应用前景.

A novel method to quantify the microscopic stages of Ulva species in seawater and its applications in forcasting green tides of the Yellow Sea

This article describes a method accurately quantifying Ulva individuals at the microscopic stages in seawater. The method was successfully applied in the field investigations at early, middle and ending stages of the large-scale green tide in the Yellow Sea in 2009 in 4 open-sea cruises, respectively. Results showed that, at the same station, more Ulva microscopic-stage individuals were detected in the surface seawater than at other water depths. The quantities of the detected Ulva individuals decreased wit...
