The effects of an industrial effluent on the photosynthetic rate of marine phytoplankton

The oceans, once believed infinitely vast and stable, have recently been subjected to considerable alteration from other than natural sources. The time has come when we must try to control these alterations and attempt to maintain the oceans as a natural system. To accomplish this we must know precisely how this intricate system operates, both physically and biologically. The energy transformations of the photosynthetic plankton lie at the beginning of this system. Logically then, priority should be given to investigations directed towards a better understanding of these basic processes. We must know the physical and biological factors involved, which factors limit the system, the composition and distribution of the plankton, and biology of these constituents. By knowing these factors we can understand the beginning of the marine ecosystem.
