Which ecological consequence results downstream when coastal upwelling weakens due to reduced offshore wind stress?

💡 Explanation

When offshore winds decrease, upwelling weakens because Ekman transport diminishes, leading to reduced vertical mixing of nutrient-rich deep water with nutrient-depleted surface water. Therefore, decreased surface nutrient concentration results, rather than increased photosynthesis, carbon storage, or oxygen levels, which require the continuation of upwelling effects.
