← GeographyWhich consequence results when Antarctic Bottom Water formation significantly slows down in the Weddell Sea?
A)Decreased global ocean oxygen levels✓
B)Strengthened North Atlantic Current
C)Weakened Walker circulation pattern
D)Increased equatorial upwelling intensity
💡 Explanation
When Antarctic Bottom Water formation slows, decreased density-driven downwelling occurs because brine rejection diminishes, lessening the supply of oxygen-rich water to the deep ocean. Therefore decreased global ocean oxygen levels result, rather than changes to the North Atlantic Current, Walker Circulation, or equatorial upwelling which are driven by different mechanisms and locations.
