COVER SeaWiFS satellite composite of Earth's biosphere (ocean chlorophyll and land vegetation), acquired between 12 and 19 July 1998. Clouds are represented in white. The dramatic phytoplankton bloom (shown as a green and yellow band) that developed in the equatorial Pacific after the demise of the 1997-98 El Niño is beautifully captured. The bloom is distorted by complex oceanic waves with a wavelength of about 1000 km. See page 2126 [Image: SeaWiFS Project, NASA/Goddard Space Flight Center, and ORBIMAGE]
