Which outcome occurs when major ocean gyres stall?

💡 Explanation

Decreased nutrient upwelling shifts localized ecosystems because gyre circulation drives the upward movement of nutrient-rich deep water via Ekman transport. This supplies surface ecosystems; therefore, diminished currents create lower surface nutrients, rather than other climate-wide phenomena.
