False-colour satellite image of the coastal waters of Peru and Ecuador,showing the distribution of phytoplankton in the surface waters. The colours represent varying phytoplankton densities from red (most dense) through orange,yellow and green to blue (least dense). Land areas are black and regions where no measurements were possible are grey. The wind-driven upwelling of cool,nutrient- rich subsurface waters in this area causes the high phytoplankton concentrations which support some of the world's largest fisheries. The image was produced from data acquired by the Coastal Zone Colour Scanner on NASA's Nimbus-7 satellite | |
