Box 775 Cambridge Maryland 216130775 USA ABSTRACT Acclimation of the photosynthetic apparatus to changes of irradiance temperature and nutrient availability involving regulation of the chlorophyll acarbon ratio g is a universal feature of all phytop Chlorophyll is a key biochemical component in the molecular apparatus that is responsible for photosynthesis the critical process in which the energy from sunlight is used to produce lifesustaining oxygen In the photosynthetic reaction below carbon The amount of chlorophyll in water is usually highest in summer and lowest in winter because of course i t is not easy for plants to grow in winter There are many human activities that affect chlorophyll in water such as sewage inputs and destructio As part of a long-term marine water quality monitoring program, the King County Dept. of Natural Resources & Parks has collected nutrient and chlorophyll data for almost 20 years at multiple subtidal locations in the Puget Sound Central Basin (Figure 1). This monitoring program has yielded a unique dataset for evaluating the effects of both large and local scale climatic conditions on phytoplankton and nutrient dynamics. .
