Nutrient gradients from the eutrophic Changjiang (Yangtze River) Estuary to the oligotrophic Kuroshio waters and re-evaluation of budgets for the East China Sea Shelf

Major sources of MeO/OH-BDEs in the East China Sea elucidated from their records and phytoplankton biomarkers

“…These results also support the contention that unidentified marine producers inhabit the surface water of the ocean and produce these natural compounds (Guitart et al, 2011). Several studies have suggested that economic necessities in China enhance the anthropogenic nutrient inputs to the ECS and then increasing primary production Zhang et al, 2007). Given the lower transformation rates from PBDEs to OH-BDEs (Erratico et al, 2010;Hamers et al, 2008;Malmberg et al, 2005;Stapleton et al, 2009) and the natural characteristic of MeO/OHBDEs (Guitart et al, 2011;Teuten et al, 2005), we speculate that the anthropogenic nutrient inputs may enhance their production.…”

Joint effect of freshwater plume and coastal upwelling on phytoplankton growth off the Changjiang River

“…According to historical records, the ECS was considered as an N-limited ecosystem as other marine ecosystems (Chen et al, 2001). The Changjiang (CJ) River holds large water discharge (annual mean ∼ 924 km 3 yr −1 ) and high nutrient concentrations, serving as the major nutrient source to the ECS (Zhang et al, 2007). Since the 1950s, rapidly growing anthropogenic activities, such as fertilizer applications, have caused ∼ 8 × increase in N concentration and fluxes in the CJ River (Wang, 2006).…”

Long-term variability of sea surface temperature in Taiwan Strait

“…Moreover, the Yangtze River outflow per se is an important seasonal heat source to ECS (Belkin 2009) since (a) the Yangtze discharge peaks in summer when riverine water is warmer than the ambient offshore water (Zhang et al 2007), and (b) the Yangtze stream temperature in the estuary increased by 2°C since the late 1960s (Fig. S5 after Zhou et al 2005, Fig.…”
