DISTRIBUTION OF NITRATES AND NITRITES IN THE WATER OF NORTH INDIAN OCEAN

Abstract

The general distribution of dissolved mineral nitrates and nitrites in the Arabian Sea, Bay of Bengal, Andaman Sea and in the open northern part of the Indian Ocean is given. Mean value of nitrates: 1 micrograms-at N/1 in surface water, sharply increasing to 22-26 micrograms-at N/1 with depth. After achieving these concentrations the content of nitrate changes little. Nitrites as a thin layer were dissolved in the thermocline layer and under it in quantities depending on zooplankton (up to 2 micrograms-at N/1). In the Arabian Sea the second maximum of nitrites was discovered (up to 5 micrograms-at N/1 in 150-1500); it can be explained by the reduction conditions of these water.
