Which effect results when upwelling brings nutrient-rich water to surface regions with stratification?

💡 Explanation

When upwelling delivers nutrients to stratified surface waters, algal blooms can occur because the nutrients fuel rapid phytoplankton growth, especially under stable conditions, sometimes resulting in harmful, toxic blooms. Therefore algal bloom proliferation is possible, rather than acidification, destabilization, or mixing which require different chemical or physical energy drivers.
