Relationships of the summer nutrient concentrations in the East China Sea with the Changjiang diluted water, upwellings and Kuroshio intrusion, from an interannual perspective

Key Points

• Nutrient concentrations correlate significantly with Changjiang diluted water input and Kuroshio intrusion.
• A substantial upwelling effect contributes to elevated nutrient levels during summer months.
• Analysis focuses on the interannual variability of nutrient dynamics related to coastal currents.
• The findings highlight potential shifts in marine ecosystems linked to changing water mass interactions.
