Which ocean process brings vital nutrients from the bottom to the surface waters?
"upwelling"
What isn't associated with upwelling?
Upwelling is when the winds cause nutrient rich waters from lower levels of the ocean to replace the surface water. Upwelling's are usually caused by coastal surges or open oceans.
How does upwelling affect the productivity of many regions of the ocean including waters off the coasts of California and Peru?
Upwelling increases productivity by lifting nutrients to the surface.
What occurs when seasonal extreme winds cause the colder lower region ocean waters to climb closer to the surface?
upwelling
Why are upwelling waters always cold?
they come from the colder waters on the bottom of the oceans
Describe at least two ways in which upwelled water might differ from the water around it?
1.Upwelling provides nutrients that supports animals and plants in surface waters. 2.Many fisheries are located in areas of upwelling because ocean animals thrive there
How does upwelling affect the distribution of nutrients of the ocean?
Upwelling brings up tiny ocean organisms, minerals, and other nutrients from the deeper layers of the water. Without this motion, the surface waters of the open ocean would be very scarce in nutrients.
How do subsurface lake waters cool down in the fall?
Upwelling/downwelling, do some research on these.
What industry is dependent upon the productive waters of an upwelling area?
The fishing industry depends on fish gathering at the nutrient rich water upwelling from deeper ocean climes.
Why are upwelling in waters always cold?
Because water at the surface is always warmer than the water at depth. You get used to the temperature of the water surrounding you. When water surges up from the depth, you notice the change in temperature.
Where are nearly all fishes caught?
harvested from coastal waters or areas of upwelling YA WELCUM
Why does the fishing industry watch for upwellings eagerly?
Most ocean waters are depleted of nutrients - plankton gets eaten by larger creatures, the larger creatures export nutrients in their wastes out of the lighted zone, where plants can grow, into the deep ocean. Where upwelling occurs, as in the Peru Current, these deep waters come to the surface carrying nutrients. This yields a phytoplankton boom, which gives fish a rich source of food. The anchovy fishery of Peru, one of the richest fisheries in the world, is directly fed by upwelling. During an el Nino event the upwelling fails - so does the fishery.
