Which outcome occurs to coastal plankton when offshore gyre circulation weakens?

💡 Explanation

Reduced offshore transport reduces coastal upwelling, therefore fewer nutrients reach the surface, and then plankton populations decline because Ekman transport weakens cyclonic eddy formation rather than altering particle sedimentation, stimulating blooms directly, or spiking sequestration.
