Which mechanism concentrates buoyant Sargassum seaweed rafts within ocean gyres?

💡 Explanation

Ekman transport creates converging surface currents due to wind stress and the Coriolis effect, driving floating material towards the gyre’s center because this mechanism moves surface water downwind and at an angle; therefore, Sargassum accumulates, rather than being dispersed by other forces.
