Hydrodynamic control on the interannual variability of algal bloom in the Pearl River Estuary from 2021 to 2024: evidences from buoy data and hydrodynamic modeling

Key Points

• Algal bloom variability is significantly influenced by hydrodynamic factors in the Pearl River Estuary, with pivotal implications for ecosystem health.
• The study identifies specific periods from 2021 to 2024 where hydrodynamic conditions affected bloom patterns due to nutrient distribution.
• Buoy data and hydrodynamic modeling were used to understand the mechanisms behind the blooms, revealing complex interdependencies.
• Supporting future management strategies, the findings highlight the need to consider hydrodynamics for effective algal bloom control.
