Which mechanism amplifies CO₂ sequestration when increased wind stress drives ocean circulation change?

💡 Explanation

When winds intensify, upwelling circulation increases leading deeper, nutrient-rich waters to surface because of Ekman transport, stimulating algal blooms. Therefore amplified CO₂ sequestration by algae results, rather than increased stratification, methane release, or reduced runoff, which don't directly increase CO₂ absorption.
