On the Cover: An advanced very high resolution radiometer (AVHRR) image showing sea surface temperature on October 8, 1991 extending from Cape Hatteras to the southern New Jersey coast. In false-color representation higher temperatures are yellow, while cooler waters are orange and red. The line indicates a ship track taken between October 10 and 11 extending from Delaware Bay to the Western Sargasso Sea. The station numbers are indicated. The ship traversed from the nutrient-poor Sargasso Sea, across the Gulf Stream, through a nutrient-rich filament of shelf water, across a region of nutrient-poor shelf-slope waters, and onto the continental shelf. The bottom panel shows the changes in variable fluorescence measured with a pump-and-probe fluorometer at the corresponding stations in near-surface natural phytoplankton communities. Note the twofold variations in the changes in the quantum yields of fluorescence, which are primarily related to nutrient availability in the given water masses. (AVRHH image was provided by R. Evans, University of Miami, and P. Minnett, Brookhaven National Laboratory.) [See article by Falkowski et el., page 84]
