How would a large increase in the salinity of an estuary Mostlikely affect the ecosystem of the estuary?
How would a large increase in the salinity of an estuary most likely affect the ecosystem of the estuary? All organisms would die. All organisms would continue to live as they now do. The number of salt-tolerant organisms would increase, and the number of salt-intolerant organisms would decrease.
Which best explains the importance of estuaries?
Which best explains the importance of estuaries? Estuaries are freshwater areas that support a large amount of living things. Estuaries are areas where freshwater and salt water collide, resulting in a large amount of biodiversity.
How does coastal upwelling enhance fish populations?
Areas of coastal upwelling and wide continental shelves are the two types of coastal areas where fishing resources are the richest. Areas of coastal upwelling have a greater supply of nutrients to support animal life. Wide continental shelves provide excellent locations for large populations too.
What causes upwelling?
Winds blowing across the ocean surface often push water away from an area. When this occurs, water rises up from beneath the surface to replace the diverging surface water. This process is known as upwelling.
Why are upwellings important to ocean ecosystems?
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 happens when upwelling occurs?
Upwelling occurs when winds push surface water away from the shore and deeper water rises to fill the gap. During upwelling, wind-displaced surface waters are replaced by cold, nutrient-rich water that wells up from below.
What is upwelling in the sea?
Coastal upwelling is the process by which strong winds blow down the coasts of continents and, in conjunction with the earth’s rotation, cause the surface waters to be pushed offshore. Water from the ocean depths is then pulled up – or upwelled – to the surface to take its place.
Which would most affect the health of fish in a local pond?
Which would most affect the health of fish in a local pond? The daily release of hot water into the pond from a local factory.

What are some benefits living in estuaries?
Estuaries have important commercial value and their resources provide economic benefits for tourism, fisheries and recreational activities. The protected coastal waters of estuaries also support important public infrastructure, serving as harbors and ports vital for shipping and transportation.
Why do we need to protect and conserve our estuaries?
Estuaries are some of the most productive ecosystems in the world and are home to many different plants and animals. Estuaries also support the U.S. economy in the form of seafood sales, jobs, and recreational activities such as fishing, bird watching, and boating.
Which best describes a significant benefit estuaries have on the environment?
Which best describes a significant benefit estuaries have on the environment? Wildlife helps protect the land from erosion in estuaries.
Why are upwelling zones generally more productive than coastal oceans?
***Why are upwelling zones generally more productive than coastal oceans? COASTAL=shallow in comparison to the open ocean with a higher proportion of the water column and higher nutrient inputs coming from terrestrial run-off. MORE TURBIDITY in coastal waters, which limits the depth reached by solar radiation.
What are upwellings and Downwellings?
Upwelling is the movement of cold, deep, often nutrient-rich water to the surface mixed layer; and downwelling is the movement of surface water to deeper depths. Downwelling occurs when surface waters converge (come together), pushing the surface water downwards.
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).
Is upwelling good or bad?
Is upwelling good or bad? Upwelling is a positive boost to the marine ecosystem by providing nutrients to enhance plankton growth, which is the basis of the ocean food chain.
What species benefit from upwelling?
Because of upwelling nutrients, krill are abundant enough to feed the largest animals on earth, baleen whales, as well as myriad penguins, seals, and seabirds.
Why would it be useful for fishers to locate areas of coastal upwelling?
why would it be useful for fishers to locate areas of coastal upwelling? It would be useful to fishers because it brings nutrients to the surface, then the fish eat the “food” making fish easier to catch.
Why is microscopic phytoplankton very important as a food source?
Phytoplankton account for about half of the photosynthesis on the planet, making them one of the world’s most important producers of oxygen. Phytoplankton rely on nutrients found in their surroundings, such as phosphate, nitrate, and calcium, to thrive.

Does upwelling increase salinity?
Coastal upwelling intensified, thus cooling the entire shelf water column by 0.4 °C. Precipitation reduced giving rise to higher upper layer salinities.
How does upwelling in the ocean affect algae populations in the area?
How does upwelling in the ocean affect algae populations in the area? The algae population grows slowly and forces marine life to move out to sea. The current produced by the upwelling forces the algae population to relocate.
