← GeographyWhich outcome results when increased trade winds strengthen coastal upwelling along western South America?
A)Decreased marine primary productivity
B)Enhanced near-surface stratification
C)Widespread coral bleaching events
D)Increased abundance of commercially valuable fish✓
💡 Explanation
When trade winds strengthen, intensified Ekman transport drives nutrient-rich deep water towards the surface through upwelling because surface water is pushed offshore. Therefore, increased fish abundance results, rather than decreased productivity, stratification, or bleaching events, which require stable or warmer surface conditions.
