Which outcome results when freshwater lenses disrupt oceanic gyre rotation?

💡 Explanation

Reduced gyre rotation reduces surface water divergence; this suppresses upwelling because Ekman transport is weakened; therefore, fewer nutrients reach the surface, rather than enhanced processes which require stronger currents or vertical mixing.
