Which outcome occurs when coastal upwelling exceeds normal limits?

💡 Explanation

Intense upwelling brings excessive nutrients to the surface that can trigger a rapid increase in algae; this is eutrophication because it leads to harmful algal blooms consuming available oxygen, therefore algal blooms intensify, rather than a bloom dying off due to lack up nutrients.
