When i used to be requested to arrange this symposium on marine producti­ vity, it made me think of what features of this topic will be stimulating to a heterogeneous crew of laboratory-oriented physiolo­ gists and biochemists. in recent times there were a number of books which discusses the method well-known in basic construction stories and defined the significance of photosynthetic CO aid 2 in a variety of parts of the world's oceans. I for this reason determined to dis­ pense with those traditional facets of basic construction and invite researchers to talk on quite a few difficulties concerning the abundance and task of phytoplankton to environmental stipulations. The lectures I invited have been therefore particularly varied in personality, yet all have been comparable both to elements affecting the speed of photosynthesis or to the destiny of lowered carbon because it passes in the course of the microbial nutrients net. as well as those talks the individuals benefited from a couple of shorter displays and poster periods which handled construction and biking of natural carbon within the marine surroundings.

The constant in equation 3 is the product of the molar absorption coefficient for cellular chlorophyll and a volume element which relates the incident level of irradiance to a one liter suspension. Equations 4-7 are phenomenological equations for the two pairs of coupled reactions shown in Figure 5. J 4 is the flux of absorbed quanta, J 3 is the rate of electron flow across reaction centers, J 2 is the rate of photosynthetic electron flow, and J l is the flux of electrons to carbon dioxide. 5 moles of electrons are transferred for each mole of carbon dioxide assimilated.
