Physical and biological processes driving seasonal variability of Nitrate budget and biological productivity in the Gabon-Congo upwelling system

Key Points

• The research aims to understand the physical and biological factors that affect the seasonal changes in the nitrate budget and biological productivity in the Gabon-Congo upwelling system.
• Utilized NEMO-PISCES model outputs for nitrate budget analysis.
• Applied Python scripts for calculations and figure generation.
• Compared model outcomes with validation datasets from PIRATA and eOdyn.
• Seasonal variability of the nitrate budget indicated critical influence from physical processes.
• Biological productivity was closely linked to changes in nitrate availability.
• Model validation showed strong agreement with observed data.
