dc.description.abstractPhosphorus and inorganic nitrogen compounds have been divided into 'reserved' andoxidative fractions based on their relationships with apparent oxygen utilization in the northern and the north-eastern basins of the Arabian Sea.Two oxygen minima are observed in the water masses north of 20 degree N latitude.The reserved nitrogen compound is negative in the deeper waters and this varies from north to south. This deficit indicates a possible loss of nitrate to gaseous nitrogen through denitrification. Spatial variation of oxidative ratios indicates changes in the rates of nutrient regeneration associated mainly with regional variations in photosynthetic productivity. A stoichiometric relationship based on the ratios of change. of nutrients in water and their ratios of concentration in plankton indicates that organisms in the Arabian Sea may have an atomic relation for C :N :P of 105 :15:l. Applying the oxidative ratios the loss of nitratethrough denitrification has been calculated to be about 2/3 of its total availability. Similarity of conditions between this area and the eastern tropical North Pacific suggests denitrification as a characteristic on the eastern sides of oceans which are poorly ventilated in the north.
