title: Data from: Nutrient sources, phytoplankton blooms, and hypoxia along the Chinese coast in the East China Sea: Insight from summer 2014

description: This dataset contains data collected onboard the R/V Ocean Researcher I
 during the summer of 2014 (August 20–31) East China Sea described in the
 paper: “C.-C. Chen, W.-C. Chou, and C.-C. Hung (2024). Nutrient sources,
 phytoplankton blooms, and hypoxia along the Chinese coast in the East
 China Sea: Insight from summer 2014, Marine Pollution Bulletin (accepted
 on July 4 2024)".
description: The designed sampling stations were located throughout the East
 China Sea, but the sampling stations in different sampling periods varied.
 Conductivity, temperature, and depth (CTD) were recorded throughout the
 water column with a CTD instrument (SBE9/11 Plus; Sea-Bird Electronic
 Inc., Bellevue, WA, USA). The water samples were collected in
 Teflon-coated Go-Flo bottles (20 L; General Oceanics Inc., Miami, GL, USA)
 mounted on a Rosette assembly (Model 1015; General Oceanics Inc.). At each
 station, 5–10 samples were taken at depths of 2–50 m, depending on the
 water depth. Subsamples were drawn from the collected water for subsequent
 analyses, including bacterial abundance, Chl a, dissolved inorganic carbon
 (DIC), dissolved oxygen (DO), nutrients, particulate organic carbon (POC),
 and total alkalinity (TA). In addition, to these analyses, onboard
 incubation was performed to assess plankton community respiration
 (plankton CR) and primary production (PP). The analyzed methods for each
 variable can be found in the paper. The data has been processed by a
 linear regression analysis using “SigmaStat” to produce a manuscript
 accepted for publication in Marine Pollution Bulletin.
