Which material accumulation consequence occurs within subtropical ocean gyres due to Ekman transport?

💡 Explanation

When wind-driven surface currents converge, Ekman transport causes water to move towards the center of subtropical gyres, concentrating floating materials because of the converging flow. Therefore plastic debris accumulates into large garbage patches, rather than hydrate destabilization, carbonate precipitation or silica dissolution at the seafloor from upwelling.
