Which risk increases when major ocean gyres stagnate?

💡 Explanation

Anoxic zone size risk increases due to decaying organic matter. Stagnation reduces oxygen replenishment because the biological pump mechanism falters; therefore, decomposition depletes dissolved oxygen rather than gyre circulation mitigating such depletion, under typical conditions.
