worldwide, there are five major coastal currents associated with upwelling areas: the canary current (off northwest africa), the benguela current (off southern africa), the california current (off california and oregon), the humboldt current (off peru and chile), and the somali current (off somalia and oman). all of these currents support major fisheries. the four major eastern boundary currents in which coastal upwelling primarily occurs are the canary current, benguela current, california current, and humboldt current. the benguela current is the eastern boundary of the south atlantic subtropical gyre and can be divided into a northern and southern sub-system with upwelling occurring in both areas. the subsystems are divided by an area of permanent upwelling off of luderitz, which is the strongest upwelling zone in the world. the california current system (ccs) is an eastern boundary current of the north pacific that is also characterized by a north and south split. the split in this system occurs at point conception, california due to weak upwelling in the south and strong upwelling in the north. the canary current is an eastern boundary current of the north atlantic gyre and is also separated due to the presence of the canary islands. finally, the humboldt current or the peru current flows west along the coast of south america from peru to chile and extends up to 1,000 kilometers offshore. these four eastern boundary currents comprise the majority of coastal upwelling zones in the oceans.
