Abstract In coastal seas, the role of atmospheric deposition and river runoff in dissolved organic phosphorus (DOP) utilization is not well understood. Here, we address this knowledge gap by combining microcosm experiments with a global approach considering relationship between activity alkaline phosphatases changes phytoplankton biomass relation to concentration inorganic (DIP). Our results suggest that addition aerosols riverine water stimulate biological DOP seas primarily depleting DIP due increasing nitrogen concentrations, which enhances growth. This “Anthropogenic Nitrogen Pump” was therefore identified make an important source for but only when ratio chlorophyll [Log 10 (Chl / DIP)] larger than 1.20. study suggests anthropogenic input might contribute cycle seas.

Environmental context External nutrients giving rise to critical ecological issues of the coastal seawater. We investigated nearshore nutrient concentrations and their sources in Xiamen Bay during 2013–18. Our results could provide theoretical support for controlling pollution. Rationale greatly increase risks Therefore, it is important understand variation characteristics nitrogen (N) phosphorus (P) area. Methodology The dissolved inorganic (DIN) phosphate (PO4–P) were monitored from 2013 2018. input runoff was calculated flow amount collected by Marine Fisheries Bureau. Atmospheric dry deposition DIN simulated using Williams model analyse potential Xiamen. Results High PO4–P levels occurred inner bay decreased dramatically outside Bay. lowest values observed summer, which consistent with temporal inputs surface atmospheric deposition. Jiulong River main source eutrophication Bay, providing more than 4 × 104 tonnes (Mg) N per year. provided 2.2 103 Mg year, accounts ~3.4–6.3% Discussion ratio enrichment varied 0.21 0.40, indicating that an contributor This study provides insight into major P highlights importance city
