← GeographyWhich shift results following slower North Atlantic Deep Water formation?
A)Decreased local marine biotic productivity✓
B)Increased equatorial atmospheric convection
C)Weakened upper-level anticyclonic steering
D)Amplified near-polar seasonal precipitation
💡 Explanation
A reduction in NADW weakens the Atlantic Meridional Overturning Circulation. This upwelling slowdown reduces nutrient transport, decreasing biotic productivity because nutrient delivery is less efficient; therefore productivity declines rather than shifting convective processes.
