Abstract
The East China Sea and southern Yellow Sea ecosystems have undergone drastic changes over the past decades. The changes in the ecosystems are attributable to both natural and anthropogenic stressors. We analyzed the seasonal and interannual variability of the sea surface chlorophyll-a in the East China Sea and the southern Yellow Sea using a suite of remotely sensed data (1998-2012). When seen on a Large Marine Ecosystem level, there seems no trend in the region. However, when seen on a sub-regional scale, heterogeneous responses can be recognized among the subregions. There was an increasing trend of chlorophyll-a in the vicinity of the Changjiang (Yangtze) River mouth, while there was a decreasing trend in the southeastern slope area which can be attributed to anthropogenic nutrient enrichment and warming, respectively. Contrary to some previous studies, our analysis clearly showed that the summer-autumn averaged chlorophyll-a decreased by about 14% in a large area (circa 178,000 km(2)) in the northeastern East China Sea after 2003 coinciding with the initial impoundment of the Three Gorges Dam. Our analysis demonstrates that our ability to detect the trends in response to multiple stressors largely depends on choosing an appropriate spatiotemporal scale.
