Which mechanism causes enhanced surface phytoplankton blooms during coastal upwelling events?

💡 Explanation

When upwelling occurs, deep ocean water rises, carrying dissolved nutrients to the surface because vertical mixing transports nutrient-rich water into the photic zone where phytoplankton reside, fueling their growth. Therefore nutrient transport causes blooms, rather than increased radiation, enhanced grazing, or reduced stratification, which have opposing or negligible effects.
