Typhoon effect on pelagic ecosystem
Description
This dataset contains data collected onboard the R/V Ocean Researcher I during the pre-typhoon (July 6–8, 2018) and post-typhoon (July 13–16, 2018) periods across transects T1 (i.e., Sts. 5, 35, and 34) and T2 (i.e., Sts. 4, 3, 2, 1, and 1A) in the southern East China Sea described in the paper: "C.-C. Chen, C.-h. Hsieh, Y.-H. Cheng, W.-J. Huang, W.-C. Chou, F.-K. Shiah, G.-C. Gong (2023). Effect of a tropical cyclone on the pelagic ecosystem of a continental shelf, Limnology and Oceanography (submitted) ". Main results of this study included fifteen figures as described in the paper, and please refer it for further details.

Methods
Seawater temperature, conductivity, and pressure were recorded throughout the water column with a CTD (SBE 9/11 plus, Seabird Electronics Inc., USA). Photosynthetically active radiation (PAR) was measured throughout the water column using an irradiance sensor (4p; QSP-200L, Biospherical Inc., USA). Samples were collected using Teflon-coated Go-Flo bottles (20 L, General Oceanics Inc., USA) mounted on a General Oceanic Rosette® assembly (Model 10151212, General Oceanics Inc.). Seawater at each station was taken at six depths at intervals of 5 to 25 m within or less than 100 m of water column depth. Extra samples were taken at 125, 150 and/or 200 m water depth for stations with depths within 125–200 m of the water column depth. Sub-samples were taken for analyses of pH, dissolved inorganic nutrients (e.g., nitrate and phosphate), Chl a, abundances of autotrophic picophytoplankton (e.g., Synechococcus, Prochlorococcus, and picoeukaryotes), and heterotrophic bacteria. Sub-samples for onboard incubation were conducted to determine primary production, bacterial production, and plankton community respiration. The methods used to collect the hydrographic data and to analyze the aforementioned response variables followed those described by Chen et al. (doi:10.3389/fmars.2022.796187). The data has been processed by a linear regression analysis using "SigmaStat" to produce a ms accepted for publication in Limnology and Oceanography.
