Abstract This study aimed to comprehend the effects of Typhoon Maria on pelagic ecosystem in southern East China Sea. Shipboard measurements were conducted at eight sampling stations before (2–4 d) and after (3–6 typhoon, which enabled evaluation potential impacts typhoon this ecosystem, with particular focus carbon dynamics. Following typhoon's passage, there was a slight drop sea surface temperature. The response variables however, exhibited variations different stations. For further analysis, t ‐tests compared variables, while type II regression assessed linear correlation between two variables. Overall, during post‐typhoon period, concentrations nitrate, chlorophyll , primary production, bacterial biomass plankton community respiration, abundance large phytoplankton (> 2 μ m) relative picophytoplankton among larger‐sized picoeukaryotes higher pre‐typhoon period. mean value fugacity CO similar or slightly lower than Although typhoon‐induced vigorous production might have absorbed significant amount decrease could been offset by respiration. findings suggest that enhanced physical disturbance increased water column mixing, which, turn, augmented nutrient availability promoted growth shallow column. sheds light complex interactions typhoons marine ecosystems highlights importance investigating these phenomena better understand their ecological implications.
