“…Some previous studies have suggested that nutrients have positive correlations with larger phytoplankton and negative correlations with smaller phytoplankton in the YS and the ECS (Deng et al, ; Sun et al, ). Indeed, higher dissolved inorganic nitrogen, phosphate, and silicate along coastlines and in the Changjiang Estuary and its adjacent areas were observed (Gong et al, ; Guo et al, ; Liu et al, ; Wang et al, ; Zhang et al, ), supporting our results that micro and nanoplankton were distributed with higher percentages in nearshore areas (Figure ). With the enhanced solar radiation in April, sea surface temperature increased and the stratification occurred in the central YS (Li et al, ; Yu et al, ), preventing the supplementary of nutrients in the surface.…”

Phytoplankton size classes (PSCs) is of great significance for exploring marine ecological and biogeochemical processes. Remote sensing of PSCs has been successfully applied to open oceans; however, it is still quite limited for optically complex coastal oceans. In this study, the entire continental shelf sea of China including Bohai Sea (BS), Yellow Sea (YS), and East China Sea (ECS) characterized by distinctive turbid waters and impacted by plumes of large world‐class river (the Changjiang River) was taken as an example of turbid coastal ocean for remotely sensed spatial‐temporal distributions of PSCs. In situ data were collected from cruises during April to June in 2014 and an improved algorithm for PSCs retrieval was proposed. PSCs derived from GOCI (Geostationary Ocean Color Imager) images revealed that microplankton was dominant in the BS, the YS, and the nearshore ECS and nanoplankton distributed widely in the entire study area, while picoplankton mainly distributed in the offshore ECS in April, which was consistent with in situ investigation and related to environmental factors. Validation indicated that the improved algorithm provided a more accurate estimation of PSCs, with the root mean square error (RMSE) between estimated and measured size‐fractionated concentrations been 0.774, 0.257, and 0.142 mg m−3 for micro, nano, and picoplankton, respectively. Diurnal variations of PSCs were mainly affected by tidal currents and light intensity depending on different water types. These illustrated that remote sensed spatial distributions as well as diurnal variations of PSCs are effective in turbid continental shelf seas of China.

“…The nutrient-rich bottom water is a result of nutrient accumulation in the south Sfax coast during the previous summer and autumn. The same results were obtained in the southern Yellow Sea [19]. In addition, in the southern coastal, the high availability of inorganic phosphate is associated with the high release of phosphogypsum [8].…”

“…This was possibly due to phytoplankton's rapid consumption, the average nutrient concentrations were low, particularly the PO 4 3-concentrations [21]. The importance of N availability may be caused by atmospheric deposition [19]. Phosphate was also reported to be a limiting element for phytoplankton growth in the western [22] and the eastern Mediterranean Sea [23].…”

“…The SYS has been considered one of the most prolific fishing grounds in the China Sea. However, in recent years, the SYS has suffered from serious environmental problems, including harmful algal blooms arising from anthropogenic causes, such as industrial wastewater, domestic sewage and over‐exploitation, leading to the rapid decline of fishery resources and degradation of coastal habitats based on long‐term observations [ Lin et al ., ; Liu et al ., ]. Since 2007, green tides have become a severe problem impacting the coastal areas of the SYS, even affecting the hosting of the 2008 Olympic Games [ Liu et al ., ].…”

The biogenic elements concentrations in a coastal bay/estuary are strongly influenced not only by riverine input but also by submarine groundwater discharge (SGD) which has been identified as a typical process of land/ocean interactions in coastal zones. To assess the role of SGD in nutrient fluxes in the Southern Yellow Sea (SYS), 228Ra activities were measured in seawater collected in May 2014. Analyzing the sources and sinks of 228Ra, the flux of excess 228Ra through SGD was estimated to be (2.2 ± 1.0) ×1015 dpm yr−1. Based on the 228Ra mass balance model, we estimated the average SGD flux to be approximately (1.3 ± 0.87) ×1012 m3 yr−1 over the entire SYS, which is at least 3.3 times the estimated annual delivery from the Changjiang River into the SYS (∼1.3 × 1011 m3 yr−1). The SGD‐derived biogenic elements loads (dissolved inorganic nitrogen (DIN), phosphorus (DIP) and silicon (DSi)) were estimated as (487 ± 384) × 109 mol yr−1, (2.8 ± 2.2) × 109 mol yr−1, and (313 ± 259) × 109 mol yr−1, respectively, which are approximately 18 times, 7 times and 13 times the riverine input from both mainland China and Korea. The accumulation nutrient fluxes derived by SGD may play one of the most important roles in the green tide bloom that originated from the Subei Shoal zone in the SYS. Additionally, DIN and DIP via SGD can provide the necessary amounts of nutrient for recovering nutrient concentrations to normal levels after the green tide bloom is terminated.
