Off the coast of Oregon and Washington, there is forceful downwelling … Nettet6. nov. 2024 · Upwelling is a phenomenon that brings cold, nutrient-rich deep water to the surface. In the Northern Hemisphere, upwelling occurs on west coasts when winds are blowing north to south. Ekman transport and the Coriolis Effect make the coastal waters move, on average, 90 degrees to the wind.
NettetIn this normal pattern (which is called the Walker Circulation ), warmer water piles up in the western equatorial Pacific Ocean — in fact, the elevation of the ocean off the east coast of Australia is as much as 40 cm higher than the elevation of the ocean surface off the west coast of South America!

The major upwellings in the ocean are associated with the divergence of currents that bring deeper, colder, nutrient rich waters to the surface. There are at least five types of upwelling: coastal upwelling, large-scale wind-driven upwelling in the ocean interior, upwelling associated with eddies, topographically-associated upwelling, and broad-diffusive upwelling in the oce…
NettetUpwelling is the process by which deep, cold water at the bottom the ocean rises to the top. This cold water is filled with nutrients. The process of upwelling takes place along coastlines as well as in the open ocean. The nutrients in the upwelled water fertilize surface water, providing them with a higher biological value. google drive of google oneNettet26. apr. 2024 · True False 4.)
