The issue of whether the increase in nutrients is supplied by increasing runoff or by enhancing upwelling in coastal marine ecosystems after a typhoon is considered controversial. This is because it is relatively difficu...
Typhoons frequently induce algal blooms in the open ocean based on the satellite remote sensing data. However, the effects of typhoons on nearshore areas are not fully clarified due to the inaccessibility of in situ samp...
The isotopic compositions (613C and 615N) and C/N ratios of suspended particulate organic matter (POM) were investigated off the east coast of Hainan Island in the South China Sea during summer. Coastal upwelling influen...
The 813C, 815N and C/N ratio of the particulate organic matter (POM) in western Guangdong waters were determined to evaluate the impacts of the coastal currents on the POM in spring and summer. The predominance of photos...
Nitrate (NO3-) concentrations and their dual isotopic compositions (delta N-15-NO3- and delta O-18-NO3- ) were measured to constrain N sources and their cyclic processes in summer using samples from the water column of t...
The impact of typhoons on the ecology of the ocean has been observed using high-accuracy satellite remote sensing data. However, few field observations in the ocean have been conducted to understand the effect of typhoon...
The multiple and complex N sources in coastal upwelling areas make it difficult to understand the behaviour of the N cycle. Stable N and O isotopes (delta N-15 and delta O-18) of nitrate (NO3-) from coastal upwelling off...

Typhoons and rainstorms (rainfall >250 mm day(- 1)) are extreme weather events that seriously impact coastal oceanography and biogeochemical cycles. However, changes in the mixing of water masses and nutrient supply indu...
Dual isotope measurements were performed on nitrate (delta N-15-NO3- and delta O-18-NO3-) in the Pearl River Estuary (PRE) and the adjacent northern South China Sea (NSCS) to investigate nitrate sources and its biogeoche...
Submarine groundwater discharge (SGD) is an important source of freshwater, nutrients, and other chemicals to the coastal water, and has significant impacts and implications for the coastal environment and ecology. Here,...
Although great efforts have been made to decrease nutrient (notably nitrogen and phosphorus) loads and lighten related environmental damages, coastal eutrophication remains a persistent environmental crisis. To estimate ...

The eutrophication degree in the coastal bay has been increasing significantly for the past years, due to the increasing nutrient discharge. However, the factors controlling sources and nitrogen (N) cycling in the differ...
Nitrate dual isotopes (delta N-15-NO3- and delta O-18-NO3- ) and NO3- concentration were measured in aerosol and precipitation in Zhanjiang, a tropical city in the southmost tip of mainland China, between November 2018 a...
