← GeographyWhich outcome is accelerated within subtropical gyres during increased radiative forcing?
A)Oceanic carbon sequestration decline
B)Enhanced deep water formation
C)Increased coastal upwelling strength
D)Strengthened thermocline stratification✓
💡 Explanation
Strengthened thermocline stratification occurs because increased surface water temperatures inhibit vertical mixing, decreasing density-driven mixing. Weaker mixing reduces nutrient upwelling; therefore stratification is amplified rather than improving sequestration, upwelling, or deep-water formation.
