Downwelling

Downwelling is a process where surface water in the ocean or a large water body sinks downward. This occurs when surface waters become dense, often due to cooling or increased salinity, and then flow downward into deeper layers. Downwelling helps transport oxygen from the surface to deeper parts of the ocean, supporting marine life below the surface. It also plays a role in distributing nutrients and maintaining global climate patterns. Essentially, downwelling is nature's way of moving surface water and its properties into the depths, balancing the overall circulation and health of the marine environment.
