Short summary
Time-series observations of nutrients and 228Ra, a groundwater discharge tracer, were carried out from spring to neap tide in the Luhuitou fringing reef at Sanya Bay in the South China Sea. Nitrate, phosphate, and silicate in the water column showed greater diurnal variation during the spring tide. Biological processes predominantly controlled the composition of nutrients, but there was less of an impact in the spring tide due to groundwater discharge in this reef system.
