Validated temperature and salinity data, seasonal composited temperature-salinity-nutrient relationships, and predicted nutrient concentration in the South China Sea

The validated temperature and salinity data are collected from World Ocean Database (WOD, version 2013, 1940–2018; nodc.noaa.gov), Argo database (argo.org.cn/, 2002–2018) and Ocean Carbon Group (OCG) data collected during 2004–2018 at Xiamen University in the South China Sea (SCS) and adjacent West Philippine Sea (WPS) (100 ‒ 125°E ; 0 ‒ 25°N). The bad data is removed according to the quality control.

Seasonal composited temperature, salinity, and nutrient relationships, i.e., Temperature-Salinity- NO3- + NO2- relationships (TSN), Temperature-Salinity-dissolved inorganic Phosphate (TSP), and Temperature-Salinity-Si(OH)4 (TSSi) in the SCS and adjacent WPS (100 ‒ 125°E ; 0 ‒ 25°N). The predicted nutrient concentrations are generated using the seasonal composited temperature and salinity relationships and the validated temperature and salinity data.
