False-colour satellite image of the Gulf of Mexico,showing the distribution of phytoplankton in the water. The colours represent varying phytoplankton densities from red (most dense) through yellow and green to blue (least dense). Land areas are black and the grey areas are data gaps. The shallow,plankton-rich coastal waters support large fisheries. The nutrient-rich waters flowing out of the Mississippi delta (centre top) produce a phytoplankton plume (pale blue) almost 800 km in length. The image was produced from data acquired by the Coastal Zone Colour Scanner,one of the instruments on NASA's Nimbus-7 satellite | |
