The Equatorial Pacific is an oceanic province characterized by nearly year-round upwelling due to the convergence of trade winds from the northeast and southeast at the Intertropical Convergence Zone. The Equatorial Pacific spans nearly half of Earth’s circumference and plays a major role in global marine new primary production. [25]
Upwelling occurs near the Galapagos Islands. This brings food supplies to the surface for Galápagos penguin. Upwelling, however, is a sporadic phenomenon; it fails to occur on a regular basis, and so the food supply comes and goes. The penguins have several adaptations to cope with this, including versatility in their breeding habits.
In the Pacific Ocean, the increase of stratification in the eastern equatorial has found to be greater than in the western equatorial. [1] This is likely to be linked to the weakening of the trade winds and reduced upwelling in the eastern Pacific, which can be explained by the weakening of the Walker circulation. [1]
The replacing upwelling water will be colder than the surrounding surface waters, again creating a strong vertical gradient in temperature that leads to the formation of a front. [2] As the location of the trade winds varies seasonally, the location of the equatorial upwelling front does so as well. [25]
There is a band of siliceous ooze that is the result of enhanced equatorial upwelling in Pacific Ocean sediments below the North Equatorial Current. In the subpolar North Pacific, upwelling occurs along the eastern and western sides of the basin from the Alaska current and the Oyashio Current. Siliceous ooze is present along the seafloor in ...
Examples include upwellings around the Galapagos Islands and the Seychelles Islands, which have major pelagic fisheries. [4] Upwelling could occur anywhere as long as there is an adequate shear in the horizontal wind field. For example when a tropical cyclone transits an area, usually when moving at speeds of less than 5 mph (8 km/h). The ...
A Wind generated current is a flow in a body of water that is generated by wind friction on its surface. Wind can generate surface currents on water bodies of any size. The depth and strength of the current depend on the wind strength and duration, and on friction and viscosity losses, [1] but are limited to about 400 m depth by the mechanism, and to lesser depths where the water is shallower.

Digital marketing mix is fundamentally the same as Marketing Mix, which is an adaptation of Product, Price, Place and Promotion into digital marketing aspect. [48] Digital marketing can be commonly explained as 'Achieving marketing objectives through applying digital technologies'.
