Which outcome occurs in coastal ecosystems when persistent offshore winds drive significant upwelling events?

💡 Explanation

When strong offshore winds promote upwelling, nutrient-rich water from the deep ocean rises because the surface water is displaced, boosting phytoplankton growth, but sometimes species produce harmful algal blooms. Therefore rapid HAB expansion results, rather than acceleration acidification, methane release or canyon erosion, which require different processes.
