Which effect occurs when multiple ocean gyres become more stratified due to freshwater input from melting glaciers?

💡 Explanation

When gyres stratify, increased density differences suppress vertical mixing because denser saltwater stays below less dense freshwater inhibiting nutrient upwelling. Therefore reduced upwelling limits nutrient availability, rather than carbon sequestration or a productivity increase, these require greater mixing and circulation.
