Steps to reproduce

1. Sampling: Seawater samples were collected and filtered on board. 2. Laboratory experiment: The concentrations of DIN and DON were analyzed using an auto nutrient analyzer (New QuAAtro39, SEAL Analytical, Germany). The TDAA concentrations were analyzed using ultra-performance liquid chromatography (UPLC) system, following liquid-phase acid hydrolysis. The pigments concentrations were analyzed using high-performance liquid chromatography (HPLC) system. Based on the ratio of each pigment to chlorophyll a (Chl a), the relative contribution of different phytoplankton groups to total Chl a was determined using the CHEMTAX program.
