Abstract: The benthic red alga Prionitis lanceolata Harvey shows an increased primary productivity in the outfall canyon of the Carmel, California, marine sewage outfall. At a distance of 20 meters from the outfall this productivity show a large reduction before again rising to a high value at approximately 20 -40 meters. The differing productivities of samples from Mission Point, Monastary Beach, and Cabrillo Point (Hopkins Marine Station) are compared in relation to the currents which were found. Possible causes for these differences in productivity are discussed. The validity of the " light and dark bottle" method of benthic algal productivity measurement used here is also discussed.
