Describe the two steps of upwelling?
Upwelling occurs when wind pushes surface ocean water away from the coastline, causing deeper, colder, nutrient-rich water to rise and replace it. This brings nutrients to the surface, fueling the growth of phytoplankton and supporting a productive marine ecosystem.
What cold currents near coastlines might indicate sites of upwelling?
Cold currents near coastlines often indicate the presence of upwelling. This is because upwelling brings cold, nutrient-rich waters from the ocean depths to the surface, leading to colder surface currents. Some examples of cold currents near coastlines that are associated with upwelling include the California Current, the Benguela Current, and the Canary Current.
What Are Upwelling currents?
Upwelling currents are oceanographic phenomena where cold, nutrient-rich water from the deep ocean rises to the surface. These currents play a crucial role in supporting marine ecosystems by promoting the growth of phytoplankton and increasing fish populations. Upwelling occurs in specific regions where surface waters are pushed away, allowing deeper waters to well up and take their place.
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.
How often does upwelling occur?
Upwelling occurs on a regular basis in specific regions around the world, such as along the west coasts of continents. The frequency of upwelling can vary depending on factors like wind patterns, ocean currents, and coastline topography. It is generally a seasonal phenomenon that is more prevalent in certain times of the year.
