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… WebIn (a) there is a divergence at the surface which depresses the surface of the ocean and raises water from beneath the thermocline towards the surface (upwelling).

WebNov 6, 2024 · 7.3: Wind driven upwelling. 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. WebAt the root of coastal upwelling is a divergent Ekman drift. And, we can easily conceive of other causes besides a coastal boundary for such divergence. Two other upwelling situations are noteworthy: one along the equator and the other at high latitudes. Along the equator, the trade winds blow quite steadily from east to west.
