Often called rain forests of the ocean, they support a wide diversity of marine life in various stages of growth. [Translate to English:] Das Auftriebsgebiet im Humboldtstrom vor der Küste Perus gehört zu den produktivsten weltweit. In fact, it may seem something of a paradox that, as far as the oceans are concerned, biologically rich areas tend to be found where waters are cold rather than warm. They not only support a large biodiversity, but also provide 20 percent of the world's fish harvest. Service, Overview One of the two joint projects coordinated by GEOMAR is called REEBUS (Role of Eddies for the Carbon Pump in Coastal upwelling Areas). false. In the southeast Atlantic this is the Benguela Current, in the northwest Atlantic the Canary Current and in the southeast Pacific the Humboldt Current. Note that the standing stock in biomass is very low in the ocean, even where productivity is high. Thus, photosynthesis is largely restricted to the upper light-penetrated skin of the ocean. Plant species inhabiting a particular area 2. 300+ LIKES. This zone is divided further into three subzones. The second joint project CUSCO (Coastal Upwelling System in a Changing Ocean) coordinated by GEOMAR focuses on the upwelling area in the Humboldt Current off Peru. This image shows ocean productivity along the East Coast from Cape Hatteras NC to the Bay of Fundy. But can they still serve this function if the oceans continue to warm, acidify, and lose oxygen, and if the wind systems driving the upwelling will change? Dies zieht kaltes, nährstoffreiches Wasser aus der Tiefe an die Oberfläche, das so die biologische Produktion antreibt. Although they occupy just fewer than two percent of the surface of the oceans, the large coastal upwelling areas on the eastern edges of the Pacific and the Atlantic are among the most biologically productive marine areas of all. 1.
