← GeographyWhich localized outcome commonly occurs due to coastal upwelling?
A)Enhanced near-surface marine productivity✓
B)Increased thermocline layer temperature
C)Decreased dissolved oxygen concentration
D)Formation of extensive coral bleaching
💡 Explanation
Coastal upwelling brings nutrient-rich water to the surface; this process, called nutrient transport, fuels phytoplankton growth because these organisms were nutrient-limited, therefore increasing productivity rather than decreasing oxygen or causing bleaching.
