Summary:Water collected from a depth of 50 m in front San Quintin Bay, during the summer 1983 was studied to determine coastal phytoplankton development. The water was separated into two glass bottles with an interior layer of neutral plastic net. A known concentration of Na sub(2)-EDTA, used as a general chelate, was added to one of them. During ten days, aliquots from both deposits were taken for the analysis of nutrients, chlorophyll and pheophytin a and phytoplankton abundance. The nutrient concentrations diminished in both containers, and became ten times lower at the end of the experiment. The maximum concentration of chlorophyll was much higher in the container with EDTA.
