Coastal upwelling occurs when winds blow along the coast, pushing surface waters away from the shoreline. This movement allows deeper, nutrient-rich waters to rise to the surface, replenishing nutrients in the euphotic zone. The influx of nutrients supports phytoplankton growth, leading to increased productivity in marine ecosystems. This process is vital for sustaining fisheries and overall ocean health.

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.

Describe coastal upwelling and the effect it has on fish populations?
Cooler deep ocean water contains many nutrients. When this water rises, due to upwelling, these nutrients rise to the ocean's surface. These nutrients can then feed fish, providing large regions of successful coastal fisheries.

What will happen if there is increased upwelling in a coastal area?
Increased upwelling in a coastal area can bring cold, nutrient-rich water to the surface, which can lead to higher primary productivity in the region, benefiting marine ecosystems. This can result in increased fish populations as there is more food available. However, excessive upwelling can also lead to hypoxic conditions and harmful algal blooms, impacting the marine ecosystem negatively.

Why does coastal upwelling occur?
Coastal upwelling occurs when winds blow along the surface of the ocean, pushing water away from the coastline. This movement creates a vacuum that allows deeper, nutrient-rich water to rise to the surface to replace the displaced surface water. Upwelling is often found along coastlines where the ocean floor is steep and where prevailing winds blow parallel to the shore, leading to enhanced productivity and supporting rich marine ecosystems.
Why is the coastal ocean often rich in plankton and many other organisms?
Process known as coastal upwelling, cold and nutrient-rich water about 60 meters below the surface is thrown to top. It feeds them

Where are the 5 most important coastal upwelling regions in the world?

Does upwelling happen in open ocean?
Yes, but one type only: equatorial upwelling!There are three types of upwelling: equatorial, coastal, and seasonal.Equatorial upwelling is caused by the winds known as the trade winds. The trade winds blow from east to west in the vicinity of the equator. On the northern side of the equator Ekman Transport is to the right (northward), and on the southern side it is to the left (southward). With water flowing directly away from the equator, both northward and southward, the equator itself has a deficit of water. Hence, water from below upwells to fill in the gap. Equatorial upwelling is most prominent in the Pacific Ocean.
