The present paper describes some results of several exploratory experiments made at the Woods Hole Oceanographic Institution in connection with a proposed study of organic production in salt waters. An attempt is made to relate the viewpoint of the present paper to the more outstanding aims of fertilization work. Aside from practical matters of aquiculture, addition of nutrients to water is a valuable tool for studying what has been called food-chain dynamics. Briefly stated, the object of the described experiments was to determine immediate effects of fertilization upon the vital activities of the phytoplankton.
