Abstract : Much of our knowledge concerning the wavelength dependence of photosynthesis in marine phytoplankton has been derived indirectly from laboratory studies of photosynthetic oxygen evolution in cultured micro-algae or on thin bladed macroscopic algae. Studies on unicellular algae have been limited to a rather few species, mostly freshwater, and naturally occurring populations have not been examined. The present investigation was undertaken to provide such information for a wider variety of marine micro-algae representing diverse pigment systems and to examine wavelength and light intensity dependence of photosynthesis in natural occurring oceanic populations. Results obtained to date are briefly summarized in this report. (Author)
