Which outcome results when deep ocean upwelling stalls?

💡 Explanation

Deoxygenation zones experience substantial lateral expansion, because *nutrient limitation* prevents surface phytoplankton blooms; therefore, less oxygen enters the water, rather than increased biodiversity due to oxygen deprivation near coasts.
