Figure F2. Chlorophyll contents in the Pacific equatorial region, from SeaWIFS satellite, September 1997-July 1998 composite. The high-productivity (light colored) band along the equator is constrained to its position by ocean circulation patterns. Red = highest chlorophyll contents, dark purple = lowest chlorophyll.
