Effects of Upwelling Because 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.

What is an upwelling and how does it affect ocean life?
Upwelling brings those lost/sunk nutrients back to the surface, which creates "blooms" of algae and zooplankton, which feed on those nutrients. These blooms then become feeding grounds for plankton feeders, then fish, etc, sustaining ocean life that lives near the surface.
How does upwelling occur Why is it important to ocean life?
The deeper water that rises to the surface during upwelling is rich in nutrients. These nutrients “fertilize” surface waters, encouraging the growth of plant life, including phytoplankton. ... Upwelling can also play an important role in the movement of marine animals.
What is upwelling and why is it important?
Upwelling occurs when surface waters diverge (move apart), enabling upward movement of water. Upwelling brings water to the surface that is enriched with nutrients important for primary productivity (algal growth) that in turn supports richly productive marine ecosystems.
How does coastal upwelling affect ecosystems?
Ecosystem productivity in coastal ocean upwelling systems is threatened by climate change. Increases in spring and summer upwelling intensity, and associated increases in the rate of offshore advection, are expected. ... With upwelling intensification, ocean acidity will rise, affecting organisms with carbonate structures.
Why are Downwellings important for marine environments?
Currents also are a major factor in ocean ecosystems. Two types of current motion, upwelling and downwelling, strongly influence the distribution and abundance of marine life. ... When currents upwell, or flow up to the surface from beneath, they sweep vital nutrients back to where they're needed most.
What effect does an El Niño event have on the organisms along coastal areas?
Kelp forests are often destroyed by storms and ocean swells. Off California, fish populations may also be reduced. Marine mammals, such as seals and sea lions, that feed on fish may be affected.
Why is upwelling important for the commercial fishery industry?
Because 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.
How does upwelling affect the availability of nutrients in the ocean?
Upwelling occurs in the open ocean and along coastlines. ... Water that rises to the surface as a result of upwelling is typically colder and is rich in nutrients. These nutrients “fertilize” surface waters, meaning that these surface waters often have high biological productivity.
What effect does El Niño have on upwelling?
During El Niño, upwelling of cooler oceanic water decreases along the S. American coast. What typically happens is that the trade winds move from S. America to Asia/Australia, and warm surface water is dragged away from the coast and colder, nutrient water rises to shallow depths.
Why is upwelling important in the ocean quizlet?
Upwelling is important because the nutrients that are brought to the surface support the growth of phytoplankton and zooplankton, which supports other life.
What is an important effect of coastal upwelling quizlet?
Coastal upwelling occurs in areas where winds blow towards to equator and parallel to the coast. Upwelling brings greater concentrations of dissolved nutrients to the ocean surface, thus promoting the growth of plankton, which in turn support extensive populations of fish and other marine organisms.
How does upwelling affect ocean acidification?
Upwelling takes place when strong winds push surface waters away from the shoreline, allowing colder, nutrient-rich water to rise from below. ... But it is also rich in dissolved CO2 and has a naturally lower pH compared to the water it replaces.
Where does upwelling occur in the ocean?
Upwelling is most common along the west coast of continents (eastern sides of ocean basins). In the Northern Hemisphere, upwelling occurs along west coasts (e.g., coasts of California, Northwest Africa) when winds blow from the north (causing Ekman transport of surface water away from the shore).
What area of the ocean is most benefited by upwelling?
Upwelling carries nutrients to the ocean bottom. Upwelling carries nutrients to the intertidal zone. Upwelling carries nutrients to the surface of the ocean.
How does upwelling and gyres impact California and its coastal area?
The upwelling further cools the already cool California Current. This is the mechanism that produces California's characteristic coastal fog and cool ocean waters. As a result, ocean surf temperatures are much colder along the Pacific coast than the Atlantic coast.
