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.
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]
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 ]
In addition, the areas of surface ocean currents move somewhat with the seasons; this is most notable in equatorial currents. Deep ocean basins generally have a non-symmetric surface current, in that the eastern equator-ward flowing branch is broad and diffuse whereas the pole-ward flowing western boundary current is relatively narrow.
Upwelling intensity depends on wind strength and seasonal variability, as well as the vertical structure of the water, variations in the bottom bathymetry, and instabilities in the currents. In some areas, upwelling is a seasonal event leading to periodic bursts of productivity similar to spring blooms in coastal waters. Wind-induced upwelling ...
James Gardner March (January 15, 1928 – September 27, 2018) was an American political scientist, sociologist, and economist.A professor at Stanford University in the Stanford Graduate School of Business and Stanford Graduate School of Education, he is best known for his research on organizations, [1] his (jointly with Richard Cyert) seminal work on A Behavioral Theory of the Firm, [2] and ...
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]
Marketing funnel encompasses several strategic approaches designed to engage customers at different stages of the buying and fidelization process. Each subset within the marketing funnel has specific objectives and targets particular interactions with customers, from initial contact to post-purchase follow-up.
