The Canary upwelling ocean current is a conveyor belt-like flow of ocean water that sweeps along the northwest coast of Africa. Winds blowing from the continent and out to sea drive the surface waters away from the coast, allowing cold, nutrient-rich waters to rush up from the ocean floor. These nutrients produce blooms of algae, which feed the microscopic animals in the water, the zooplankton, which are an important link in the food chain, which produces the rich fisheries here in the North Atlantic.
