“…Tide, through a tidal mixing effect or internal tide, plays a key role in modulating or intensifying the upwelling, such as around the Taiwan Bank or southwest of Hainan Island (Table ). For the upwelling around the Taiwan Bank, upward transport of the SCS water carries cold water from the subsurface layer to a depth of approximately 25 m near the Taiwan Bank, then strong tidal mixing forces this upwelled water further upward to the surface or near the surface layer [ Hong et al ., ; Jiang et al ., ]. For the summertime upwelling off the southwestern coast of Hainan Island, the existing tidal mixing front [ Hu et al ., ] has been identified as a vital factor triggering the upwelling [ Lü et al ., ].…”

East Asian marginal seas surrounding China exhibit rich ocean upwelling, mostly in response to the southwesterly summer monsoon. Upwelling in the China seas, namely, the South China Sea, the Taiwan Strait, the East China Sea, the Yellow Sea, and the Bohai Sea, has become increasingly important because the potential changes in the upwelling may have dramatic ecosystem, socioeconomic, and climate impacts. This paper reviews the progress of upwelling studies in the China seas since the year 2000, by presenting the principal characteristics and new understanding of 12 major upwelling regions in the China seas. Upwelling exhibits long-term variability at intraseasonal to multidecadal scales as well as short-term variability frequently caused by tropical cyclones. It is also associated with the El Niño-Southern Oscillation, local environmental variation, and biogeochemical factors. The coastal upwelling around Hainan Island and the upwelling or cold dome northeast of Taiwan Island are specifically highlighted because they have attracted great interest for decades. This paper summarizes upwelling mechanisms in terms of wind, topography, tide, stratification, and background flow, with applications mostly to the China seas. Finally, we propose some topics for future upwelling research, i.e., potential intensification of coastal upwelling under global climate change, downwelling, intrusion of upwelling into coastal embayments, and the influence of upwelling on fishery and biogeochemical processes.

“…Site 5 had the lowest metal concentrations perhaps mainly because the waters there are from the Kuroshio branch (Chen and Wang 2006;Hong et al 2011;Qiu et al 2011), which is of an open-ocean origin. Sites 1-4 are also affected by the Kuroshio branch but sediments from Taiwan played a major role (Liu et al 2008a, b).…”

The concentration and geochemical fractionation of six trace metals related with environmental quality assessment, namely Cd, Cr, Cu, Ni, Pb, and Zn, in 30 surface sediments from both inshore and offshore areas of the Taiwan Strait were measured to investigate their distribution characteristics, evaluate their potential mobility, and assess their pollution status. The geoaccumulation index results indicated that, on average, the studied metals presented an order of Cd>Pb>Ni>Zn>Cu>Cr and were practically in uncontaminated status except Cd. The results of the sequential extraction analysis indicated that, on average, the studied metals were mostly accumulated in residual fraction except Cd whose concentration was the highest in the acid soluble fraction presenting a high risk to the environment, and their mobility decreased in the sequence of Cd>Pb>Ni>Cu>Zn>Cr. Based on the mean probable effect level quotients, the combination of the studied metals had an 8 % probability of being toxic at two sampling sites and had a 21 % probability of being toxic at the rest of sites. The spatial distribution of the studied metals in total concentrations and different geochemical fractions corroborated the previous findings about the possible sediment transportation routes in and around the Taiwan Strait.

“…Circulation in the TWS is mainly controlled by the strong East Asia monsoon and the complex topography of the Strait (Hong et al, 2011a;Naik and Chen, 2008;Tseng and Shen, 2003). In winter, the Zhejiang-Fujian Coastal Current flows southward along the eastern coast of China, but the direction of the current on the eastern side of the TWS is still not well defined (Chen and Sheu, 2006;Chen and Wang, 1999;Wu and Hsin, 2005).…”
