dc.description.abstract | Since the impoundment of the Three Gorge Dam (TGD) in 2003, many researchers were concerned about the potential impact of the dam on the East China Sea ecosystem. However, long-term influence of the TGD on the adjacent coastal water has not been well examined. Here, we analyzed the seasonal and inter-annual variation of surface chlorophyll-a, photosynthetic active radiation, sea surface temperature, and euphotic depth in the East China Sea according to the three TGD periods using the SeaWiFS and MODIS-aqua merged satellite data Pre-TGD (1998-2002), Trans-TGD (2003-2007), and Post-TGD(2008-2012). The study area was divided into six regions based on the K-means clustering of empirical orthogonal function scores. Our result suggest that the area where a significant increase in chlorophyll-a attributable to TGD was confined to the vicinity of Changjiang river mouth while a decrease or no clear pattern was observed in the other part of the East China Sea. The consistent decrease in the chlorophyll-a in the continental slope region can be explained by the warming in the region over the period. been well examined.
