The distribution of nitrogen contained in the particulate matter suspended in the sea has been studied in the Sargasso Sea, on the outer slope of Georges Bank, and in the Gulf of Maine. In the oceanic water the concentration of nitrogenous particulate matter declines sharply with depth to 500 meters and tends to increase slightly below 1,400 meters. On the outer slope of Georges Bank the distribution is similar down to 300 meters, but the concentrations are about twice as great as in mid-ocean at comparable depths. In the Gulf of Maine the nitrogenous particulate matter is more uniformly distributed with respect to depth and is present in greater amounts in the subsurface water than on the outer slope of Georges Bank.
