Since upwelling displaces the warmer water with less or no nutrients (located on the ocean surface) with the colder water with more nutrients (located near ocean floor), upwelling water contains more nutrients.
These nutrients come from dead or decaying organic matter on the ocean floor, which release nutrients like phosphate and nitrate. When these nutrients are brought up to the surface water, phytoplankton use these nutrients, along with energy from the sun, to perform photosynthesis and produce organic compounds.

How would upwellings contribute to the fishing industry of various nations?
Upwellings in the oceans are associated with the bringing of very nutrient-rich waters to the surface. Those nutrients are the base of a food chain that includes fish. Areas of upwelling are usually extremely prolific fisheries.
A treeless shallow area usually covered with water is called a?
Wetlands are treeless shallow areas usually covered with water. They are transitionally between terrestrial and aquatic ecosystems. They are among the most biologically productive natural ecosystems in the world.
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.
What happens when warm and cold currents meet?
Areas where warm and cold currents meet tend to have regular foggy conditions, as the overlying warm and cold air come in contact with each other.they also tend to have high biological productivity, because plankton growth is encourage by the mixing of warm and cold currents.Some of the world's most productive fishing grounds are located where warm and cold currents converge.For example, where Labrador current (cold) and Gulf stream (warm) meet, a dense fog is there and it is one of the richest fishing grounds of the world.
How does tsunami affect the life of fishing families in the coastal areas?
Tsunamis can devastate the livelihoods of fishing families in coastal areas by destroying their boats, gear, and infrastructure, as well as disrupting fish populations and habitats. This can lead to economic hardship, food insecurity, and loss of income for the families who depend on fishing for their sustenance. The rebuilding process can also be prolonged and challenging, impacting their way of life for years to come.

What animals are affected by upwelling?
Various marine animals are affected by upwelling, such as plankton, fish, seabirds, and marine mammals like whales and seals. Upwelling brings nutrient-rich waters to the surface, supporting the growth of phytoplankton, which forms the base of the marine food chain and attracts many different species to feed in these productive areas.
Fish are abundant in areas where the ocean is upwelling because it -?
Fish are abundant in areas where the ocean is upwelling because the upwelling brings nutrient-rich water to the surface, which supports the growth of phytoplankton. Phytoplankton is the base of the marine food chain, providing food for small fish which in turn attract larger fish and predators. This creates a productive and diverse ecosystem where fish thrive.
How does upwelling occur?
Upwelling occurs when strong winds push surface water away from the coast, causing cold, nutrient-rich water from the ocean depths to rise and replace it. This nutrient-rich water supports the growth of phytoplankton and other marine life, making upwelling areas biologically productive.
Why are many successful fisheries located near areas of upwelling populations large near upwelling?

Why is upwelling important to the earth?
Upwelling is important because it brings nutrient-rich waters from the deep ocean to the surface, promoting productivity and supporting diverse marine ecosystems. It also plays a role in regulating global climate by influencing ocean circulation patterns and carbon cycling. Additionally, upwelling areas are often important fishing grounds due to the abundance of marine life.
Where surface current carry water away from an area an upwelling may occur what is that wells up what does carry with?
In areas where surface currents carry water away, upwelling occurs as deeper, nutrient-rich water rises to the surface to replace the displaced surface water. This upwelled water is typically rich in nutrients like nitrates and phosphates, which support phytoplankton growth, forming the base of the marine food web. As a result, upwelling zones are often highly productive and support diverse marine ecosystems.
Why do fisher man like when upwelling occurs?
The cold water contains high concentrations of nutrients produced when dead organisms decayed at depth. This causes fish it be attracted to areas of upwelling.
Where are nearly all fishes caught?
harvested from coastal waters or areas of upwelling YA WELCUM
What human activities can influence the size of catches in some fishing areas in north America?
By not polluting and over fishing in the same areas
Where are Canada's fishing areas?
the pacific ocean.
In which zone do commercial fisherman seek large catches?
Commercial fishermen typically seek large catches in the continental shelf zone, which extends from the shoreline to the edge of the continental plate. This area is rich in nutrients and supports diverse marine life, making it ideal for fishing. Additionally, fishermen often target specific regions within this zone, such as fishing banks and upwelling areas, where fish populations are particularly abundant.
