An existing equation for the estimation of primary production from chlorophyll and light data was examined, and revisions were made to allow more precise applications of the equation to upwelling areas and other regions with relatively large fluctuations in chlorophyll concentration and production per unit of chlorophyll during the day. The revised equation was developed by estimating production in 2-hr increments through the daylight period, and integrating by parts to arrive at production in terms of gC m−2 day−1. Total daily production in coastal waters was estimated within ± 13% of mean 14C estimates, on the average, while in offshore waters the estimates averaged within ± 21% of mean 14C estimates. Estimates by the revised equation averaged 52% better in coastal waters, and 32% better in offshore waters, than the basic, unrevised equation.
