| 摘 要： | 利用不同空间分辨率、多时相卫星遥感数据,对2007-2010年间黄海、东海发生的绿潮(大型绿藻——浒苔)进行了监测与评估.江苏北部浅滩沿岸水体浑浊,浒苔在该海域中光谱混合现象严重,高空间分辨率的遥感影像有利于其检测;在水体极浑浊的射阳河口检测到的浒苔离岸最近距离为1 km左右.反演结果表明,浒苔在5月初会沿苏北沿岸流向...

| Abstract: | 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. |
