Upwelling in oceans brings deep nutrient-rich water to the surface, supporting primary productivity.
Upwelling is a process in oceans where deep nutrient-rich water rises to the surface due to diverging surface currents. The deep water is rich in nutrients because it contains organic matter and dead organisms that have settled at the bottom over time. This upwelling phenomenon supports high levels of primary productivity in the oceans, impacting marine life and ecosystem dynamics.
