Water temperature, salinity, nutrients, radium isotopes, and other parameters taken by CTD from the research vessel Onnuri in the Yellow and East China Seas from 2017-02-07 to 2017-02-14 (NCEI Accession 0200368)

This dataset contains water temperature, salinity, and other parameters taken by CTD and water samples from research vessel Onnuri of the Korean Institute of Ocean Science and Technology in the Yellow and East China Seas during February 7–14, 2017. Seawater samples were obtained using 10-liter Niskin bottles mounted on a Rosette frame fitted with a CTD. Hydrophysical data were measured using SBE 911-plus CTD. Nutrient samples were vacuum-filtered using 0.7-μm Whatman GF/F filters and kept frozen until analysis. Dissolved inorganic nitrogen (DIN = NO3- + NO2- + NH4+) and phosphorus (DIP = PO43-) concentrations were measured using an auto nutrient analyzer (New QuAAtro39, SEAL Analytical). 228Ra was measured using a high-purity Germanium well-type detector. Data are in CSV format.
