What is the Humboldt Current and how does it affect the coastal ecosystem of Peru?

4. What is the Humboldt Current and how does it affect the coastal ecosystem of Peru? Answer: The Humboldt Current is a cold water current from Antarctica that travels north up the coast of Peru. The cold water causes an upwelling of nutrients that feeds phytoplankton and leads to a highly productive ecosystem.

How does the Humboldt Current affect the coastal ecosystem of Peru?

THE HUMBOLDT CURRENT, also known as the Peru Current, is an ocean current that flows along the western coast of South America, affecting the water and air temperatures of coastal CHILE and PERU. … The Humboldt Current creates one of the largest and most productive marine ecosystems in the world.

How does the Humboldt Current affect the climate of the South American coast?

Humboldt current is a cold ocean current flowing towards the north along the west coast of South America from the southern part of Chile to northern Peru. Thus, it brings cold water into warm water areas of northern Peru having a cooling influence in the climates of these regions.

How does the Peru Current affect climate?

The Peruvian Current affects Peru year round, and moderates the climate of Chile in spring and summer, when it displaces a subtropical center of high pressure. Ordinarily the coast of Chile would warm in spring and summer, but the onset of the Peruvian Current diminishes temperatures and forestalls any rain.

How does the Pacific ocean affect Peru?

El Nino is the slight warming of the waters in the Pacific Ocean and is known to affect the weather around the world. … This allows cool water to well up around the coast of South America. The cool water is rich in nutrients and fish, providing rich pickings for the Peruvian fishing industry.

How does the Humboldt ocean current impact the western coast of South America?

The Humboldt Current is a cold water ocean current that flows north from Antarctica along the west coast of South America, bringing nutrient rich water to the Galapagos Islands and helping to sustain the islands rich biodiversity.

How does the Humboldt Current affect life in the Galapagos?

The impact of the Humboldt Current on seasons in Galapagos

This means less sea water evaporates from the surface; so fewer clouds are formed; decreasing the amount of rain that falls and making this the ‘dry season’.

Why is the Humboldt Current so important?

The Humboldt Current is a highly productive ecosystem. It is the most productive eastern boundary current system. … The system’s high productivity supports other important fishery resources as well as marine mammals (eared seals and cetaceans) and seabirds.

In which ocean is the Humboldt Current?

Peru Current, also called Humboldt Current, cold-water current of the southeast Pacific Ocean, with a width of about 900 km (550 mi). Relatively slow and shallow, it transports only 350,000,000–700,000,000 cu ft (10,000,000–20,000,000 cu m) of water per second.

How does the California Current affect climate?

But the California Current has a big effect on the climate of the West Coast of the United States. Summer temperatures differ less from winter temperatures along the West Coast than they do inland. Usually, the climate along the West Coast is cooler than the climate of inland areas at the same latitude and elevation.

How does Humboldt Current affect the climate of the nearby countries?

The Humboldt/Peru Current

The current has an impacting cooling influence in the climates of the Galapagos Islands, Ecuador and Peru. It is also responsible for the dryness of the costal areas of these three countries since the current cools the marine air which, in turn, causes little or no precipitation.

What is the relevance of Humboldt Current for the lives of various species in the ocean?

It is one of the major nutrient systems of the world, bringing nutrients up into the surface waters of the ocean. This supports an extraordinary abundance of marine life. … About 18-20% of the world’s fish catch comes from the Humboldt Current. The species are mostly pelagic: sardines, anchovies and jack mackerel.

Where does the Humboldt Current end?

The current flows northwards from the South Pacific Ocean, carrying waters for thousands of kilometers. The water then mixes with the warm waters at the equator, which marks the end of the Humboldt Current.
