Ocean up welling is a term to describe the water rising from the deep depths of the ocean floor because of specific wind patterns. Upwellings are caused by strong seasonal winds moving surface coastal water out from the coast and leaving a space that the upwelling fills in.

What cold currents near coastlines might indicate sites of upwelling?
The cold currents flowing along the ocean floor displaces the warmer water upward, which shows sites of upwelling.
Describe the two steps of upwelling?
Upwelling is water raising from deep in the ocean to the surface. It can be caused by wind ar density currents.
When is upwelling weaker during a normal pattern El Niño or La Nina event?
During El Nino upwelling is weaker. During La Nina upwelling increases. During a normal pattern the upwelling rises.
How do cold deep water upwellings increase organisms in an area?
Upwelling is a process in which currents bring deep, cold water to the surface of the ocean. Upwelling is a result of winds and the rotation of the Earth. There are many reason's how could deep water upwelling increase organisms in an area, here are a few:Biodiversity and productivityBecause the deep water brought to the surface is often rich in nutrients, coastal upwelling supports the growth of seaweed and plankton. These, in turn, provide food for fish, marine mammals, and birds.Upwelling generates some of the world's most fertile ecosystems. A 25,900-square-kilometer (10,000-square-mile) region off the west coast of Peru, for example, undergoes continual coastal upwelling and is among the richest fishing grounds in the world. Overall, coastal upwelling regions only cover 1 percent of the total area of the world's oceans, but they provide about 50 percent of the fish harvest brought back to shore by the world's fisheries.During El Niño, a weather phenomenon that typically occurs every three to seven years, the Pacific Ocean's climate changes dramatically. The transition zone between warm surface water and cold deep water deepens. Trade winds are also weak during El Niño. The combination of weak winds and deeper water limits upwelling. The reduction in nutrient-rich water leads to a lower fish population in the area, and therefore to a smaller fish crop.Animal movementUpwelling affects the movement of animal life in the area. Tiny larvae---the developing forms of many fish and invertebrates---can drift around in ocean currents for long periods of time. A strong upwelling event can wash the larvae far offshore, endangering their survival.Coastal climateThe cold water welling up to the surface cools the air in the region. This promotes the development of sea fog. The city of San Francisco, California, is famous for its chilly, foggy summers, brought on by seasonal upwelling in the area.
What does upwelling bring to the surface of the ocean?
Upwelling involves a wind-driven motion of nutrient-rich water towards the ocean surface. The nutrient-rich upwelled water stimulates the growth and reproduction of primary producers. This produces more fish for humans.
What brings upwelling to the surface?
surface currents
What cold currents near coastlines might indicate sites of upwelling?
The cold currents flowing along the ocean floor displaces the warmer water upward, which shows sites of upwelling.
Upwelling off the California coast is caused by?
density currents and Earth's rotation
How is a density current related to upwelling?
Density currents are warm water rising up, while upwelling is cool water rising. So they're opposites.
Upwelling and downwelling?
Upwelling is caused by currents on the surface. When water moves from the bottom of the ocean towards the surface it is called upwelling. Downwelling is when more dense water sinks. This process moves nutrients back to the deep part of the ocean.
What do you mean by upwelling?
Ocean upwelling is a phenomena where cooler deep ocean currents come to the surface, with the usual mechanism being the driving of the water by wind. A more general definition is one that includes the idea of "rising from below or within" as an upwelling of emotion. Here are a couple of sentences: An upwelling of anger fueled his outburst.The thought of the passing of her uncle triggered an upwelling of tears.
Where surface currents carry water away from an area an upwelling may occur what is that wells up?
cookies and cream
What is the process of upwelling?
Upwelling in biology is the process in which nutrient rich soil that is located deeper in the ocean rises to the surface due to ocean currents and winds. This is important because it allows the organisms living at the surface to get their needed nutriends
Describe the two steps of upwelling?
Upwelling is water raising from deep in the ocean to the surface. It can be caused by wind ar density currents.
What has the author Andrew Bakun written?
Andrew Bakun has written: 'Coastal upwelling indices, west coast of North America, 1946-71' -- subject(s): Indexes, Upwelling (Oceanography), Marine animals, Ocean currents, Aquatic biology 'Daily and weekly upwelling indices, west coast of North America, 1967-73' -- subject(s): Upwelling (Oceanography)
What causes cold spots when swimming in a warm lake?
Deeper colder water can be churned up by currents in a lake. The currents can be caused by wind or upwelling (water introduced from below) the stratification of water in a lake is a very complex mater.
What ocean current most affects the weather in north America?
The Ocean Current that most affects the weather in North America is probably the EL NINO or the UPWELLING Currents.
