The Yellow Sea is a shallow marginal sea with a large tidal range. In this study, ten areas located along the western coast of the Korean Peninsula are investigated with respect to remotely sensed water quality indicators derived from NASA MODIS aboard of the satellite Aqua. We found that there was a strong seasonal trend with spatial heterogeneity. In specific, a strong six-month phase-lag was found between chlorophyll-a and total suspended solid owing to their inversed seasonality, which could be explained by different dynamics and environmental settings. Chlorophyll-a concentration seemed to be dominantly influenced by temperature, while total suspended solid was largely governed by local tidal forcing and bottom topography. This study demonstrated the potential and applicability of satellite products in coastal management, and highlighted find that remote-sensing would be a promising tool in resolving orthogonality of large spatio-temporal scale variabilities when combining with proper time series analyses.
黄海是一个潮差大的浅边缘海。在本研究中,我们针对搭载在Aqua卫星上的美国国家航空航天局(NASA)中分辨率成像光谱仪(MODIS)获取的遥感水质指标,对朝鲜半岛西海岸沿线的十个区域进行了调查。我们发现存在强烈的季节趋势且具有空间异质性。具体而言,由于叶绿素a和总悬浮固体的季节性相反,二者之间存在强烈的六个月相位滞后,这可以通过不同的动力学和环境背景来解释。叶绿素a浓度似乎主要受温度影响,而总悬浮固体在很大程度上受当地潮汐力和海底地形控制。本研究证明了卫星产品在海岸管理中的潜力和适用性,并强调发现当结合适当的时间序列分析时,遥感将是解决大时空尺度变异性正交性的一个有前途的工具。
