Physico-chemical parameters of water samples from the South Yellow Sea, China

This dataset includes one figure and six tables with results from water samples collected from the coast of the South Yellow Sea, China. Figure S1 shows the laboratory experiment results for radium contributed from suspended particles. Table S1 includes the original physico-chemical data collected in the Subei Shoal region from 2016-2017. Table S2 includes the data collected from two coastal investigations from 2017 to 2018. Table S3 shows the nutrient concentrations and stoichiometry ratios in coastal groundwater and seawater samples from 2016-2018. Table S4 is the calculated water age among three cruises based on different age models. Table S5 is the original 226Ra activities in the open Yellow Sea collected from published accounts. Table S6 represents the comparison of estimated SGD fluxes normalized to shoreline length in different regions worldwide.
