英文摘要:
Stable isotopic signatures (δ13C and δ15N) and C/N ratios of suspended particulate organic matter (POM) were investigated from the surface water of Daya Bay during summer and winter of 2015. The relatively high δ13CPOMvalues suggested the input of13C-depleted terrigenous organic matter was low in Daya Bay. There were significant correlations between δ13CPOMvalues and chlorophyll a concentrations both during summer and winter, suggesting the δ13CPOMvalues were mainly controlled by the phytoplankton biomass in the surface water. The distribution of δ15NPOMvalues was more complicated than that of δ13CPOMand displayed low values in the outer bay and the Dan'ao River estuary.15N-depleted ammonia originating from industrial wastewater might have strongly influenced the water quality and stable isotopic signatures of POM near the Dan'ao River estuary. The δ13CPOMand δ15NPOMvalues strongly reflect the influences of anthropogenic activity and eutrophication in Daya Bay. � 2016 Elsevier Ltd
