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...
