Sentences with phrase «eastern ocean upwelling»

The Pacific Ocean may be primed by reduced solar activity to more eastern ocean upwelling of cold and nutrient rich water burping carbon dioxide back into the atmosphere — and what energy there was in the western Pacific has dissipated off the eastern margin.

Not exact matches

The Humboldt Current Large Marine Ecosystem (off Chile and Peru), the Benguelan Current LME (Namibia and South Africa), the Canary Current LME (Morocco), are the other main upwelling ecosystems, all driven by similar oceanographic and atmospheric processes, all on the eastern sides of ocean basins (western sides of continents).

In both hemisheres cold polar winds and storms pushing into lower latitudes are spinning up the oceanic gyres and increasing deep ocean upwelling in the eastern and central Pacific in the self reinforcing pattern of the Interdecadal Pacific Oscillation.

Enhanced north / south blocking patterns in periods of low solar activity enhance flow in the Peruvian and Californian Currents facilitating increased eastern Pacific upwelling of cold and nutrient rich water from the deep ocean.

El Niño - Pacific Ocean trade winds slow and almost stop which brings warmer conditions and weak upwelling currents to the eastern Pacific which hurts fishing in Peru

The persistent upwelling of cold water in the eastern tropical Pacific would have reduced cloud cover there, via reduced oceanic evaporation, and thus allowed more of the sun's energy to enter the tropical ocean - this would have aided the ocean warming process, as generally the case when the tropical ocean is cooler - than - normal.

When the wind - driven ocean circulation is intense, such as during the negative phase of the IPO & La Nina, there is strong upwelling of cold deep water along the equator, and along the eastern coasts of the continents.

Deep ocean currents occasionally push through the warm surface layer in the south eastern Pacific in one of the major areas for upwelling on the planet.

In the Pacific Ocean more flow in the Peruvian and Californian currents trigger more frigid and nutrient rich upwelling in the north - eastern and central Pacific.

By far the most significant deep ocean upwelling is in the eastern and central Pacific.

This is nutrient rich water upwelling from the deep ocean in the Eastern Pacific.

The planetary cooling from the mid 1940's was most clearly associated with a shift in the Pacific Ocean to more cold water upwelling in eastern Pacific.

The cold sub-polar water displaces the warm surface layer nearer the equator and facilitates cold water upwelling on the eastern margin of the Pacific Ocean.

Warm water piled against Australia and Indonesia surges eastward deepening the thermocline on the eastern margin and inhibiting deep ocean upwelling.

There is also an increased upwelling of deep cold ocean waters and more intense uprising of surface air near South America, resulting in increasing numbers of drought occurrences, although fishermen reap benefits from the more nutrient - filled eastern Pacific waters.

The well - known decrease in pressure from 1976 to 1977 is analogous to transitions that occurred from 1946 to 1947 and from 1924 to 1925, and these earlier changes were also associated with SST fluctuations in the tropical Indian (Figure 3.29, lower) and Pacific Oceans although not in the upwelling zone of the equatorial eastern Pacific (Minobe, 1997; Deser et al., 2004).

Accordingly, upwelling of waters acidified by anthropogenic CO2 has led to a further decrease in surface pH, as reported in the eastern Pacific Ocean along the west coast of North America, from central Canada to northern Mexico, where shoaling of the layer of seawater undersaturated with aragonite increased the frequency and magnitude of coastal acidification associated with upwelling events (Feely et al. 2008, 2010).

During El Niño, this equatorial upwelling is suppressed in the eastern and the central Pacific Ocean, reducing the supply of CO2 to the surface.

Reduced equatorial cloud cover during La Nina (due to the cooler sea surface temperature), combined with the strong upwelling (Ekman suction) in the eastern equatorial Pacific, does indeed lead to greater warming of the ocean - because it's bringing cool subsurface water to the surface, where it can be heated by the sun.

Upwelling is most common along the west coast of continents (eastern sides of ocean basins).

But we argue here that only small (2 nM) increases in the iron concentration in source waters of the upwelling Equatorial Undercurrent are needed to fuel intense diatom production across the entire eastern equatorial Pacific Ocean.
