Algal Blooms in the Pearl River Estuary.

The concentration of chlorophyll was analysed from satellite images collected by using the Medium Resolution Imaging Spectrometer (MERIS) sensor on the Envisat satellite, over the period 2004-2006 to understand the spatial and temporal aspects of algal blooms that occurred in the enclosed and semi-enclosed bays of the South China Sea in the Pearl River Estuary region. The ocean colour data obtained by processing the MERIS images in BEAM and the EnviView program was used to derive chlorophyll (Chl.) concentration to elucidate seasonal factors affecting the spatial and temporal distribution and abundance of algal blooms.

本数据集通过分析2004至2006年间搭载于恩维萨特（Envisat）卫星的中分辨率成像光谱仪（Medium Resolution Imaging Spectrometer，MERIS）所采集的卫星影像，对叶绿素浓度进行测定分析，旨在厘清南海珠江口区域封闭与半封闭海湾内藻类水华（algal blooms）的时空分布特征。研究借助BEAM与EnviView程序处理MERIS影像得到的海洋色度数据，反演得到叶绿素（Chl.）浓度，以此阐明影响藻类水华时空分布与丰度的季节影响因素。
