Short summary
We conducted an underway measurement of dissolved O2 / Ar using membrane inlet mass spectrometry and estimated net community production (NCP) in the South China Sea (SCS) in both summer and autumn. We found that nutrient content, especially nitrogen, is the dominant factor affecting primary production in the SCS. In the summer, we observed a rapid response of the ecosystem to episodic nutrient supply induced by eddies. This is the first report on NCP estimation based on O2 / Ar data in the SCS.
