Description:
Oceanic eddies having scales from several hundred meters to several hundred kilometers are ubiquitous phenomena in the World’s ocean. This became evident only after they could be observed from satellites and space shuttles. Here we present several images taken in different spectral bands which show signatures of eddies of different spatial scales in sea areas around Africa. In particular, we present a series of satellite images showing the propagation of a small-scale cyclonic (cold) eddy generated at Cap-Vert at the coast of Senegal into the open ocean. We show that this small-scale eddy transported nutrients from the Senegal upwelling region westward into the oligotrophic North Atlantic thus giving rise to enhanced chlorophyll-a concentration there. Since eddies are also areas of high fish population, knowledge of their position and properties is of great importance for fishery.
