Landsat-TM (Theme Mapper) and EOS (Earth Observing System)-MODIS (MODerate resolution Imaging Spectrora-diometer) Terra/Aqua images were used to monitor the macro-algae (Ulva prolifera) bloom since 2007 at the Yellow Sea and the East China Sea. At the turbid waters of Northern Jiangsu Shoal, there is strong spectral mixing behavior, and satellite images with finer spatical resolution are more effective in detection of macro-algae patches. Macro-algae patches were detected by the Landsat images for the first time at the Sheyang estuary where is dominated by very turbid waters. The MODIS images showed that the macro-algae from the turbid waters near the Northern Jiangsu Shoal drifted southwardly in the early of May and affected the East China Sea waters; with the strengthening east-asian Summer Monsoon, macro-algae patches mainly drifted in a northward path which was mostly observed at the Yellow Sea. Macro-algae patches were also found to drift eastwardly towards the Korea Peninsular, which are supposed to be driven by the sea surface wind.
自2007年起，陆地卫星-专题制图仪（Landsat-TM）以及地球观测系统（EOS）-中分辨率成像光谱仪（MODIS）的陆地/水色卫星影像被用于监测黄海和东海的大型海藻（浒苔）爆发情况。在苏北浅滩的浑浊水域，存在强烈的光谱混合现象，空间分辨率更高的卫星影像在检测大型海藻斑块方面更为有效。在以极浑浊水域为主的射阳河口，首次通过陆地卫星影像检测到大型海藻斑块。中分辨率成像光谱仪（MODIS）影像显示，苏北浅滩附近浑浊水域的大型海藻在5月初向南漂移并影响了东海水域；随着东亚夏季风增强，大型海藻斑块主要向北漂移，这种情况大多出现在黄海。还发现大型海藻斑块向东朝着朝鲜半岛漂移，推测这是由海面风驱动的。
