DISTRIBUTION OF PHOSPHATES AND SILICIC ACID IN THE WATER OF THE NORTHERN PART OF THE INDIAN OCEAN
Abstract
The distribution of the dissolved mineral phosphates and silicates in water of the northern part of the Indian Ocean is discussed. The content of phosphates in surface water oscillates from 0.1 microgram-at P/1 (Bay of Bengal and Andaman Sea) to 0.4 microgram-at P/1 (Arabian Sea and to southeast of Ceylon) and depends on seasons. The maximum content of phosphates in the Arabian Sea and the Bay of Bengal is 2.9 micrograms-at P/1 and to the south of 10 degrees S in the open part of the Indian Ocean the maximum content of phosphates is 2.4 micrograms-at P/1. The content of total organic phosphorus is not more than 0.5 micrograms-at P/1. The distribution of dissolved silicates is characterized by constant increase from the thermocline layer to the bottom. The maximum content of silicates is 150-160 micrograms-at Si/1 in the Arabian Sea, 140 micrograms-at Si/1 in the Bay of Bengal and 130-140 micrograms-at Si/1 in the open northern part of the Indian Ocean. The content of dissolved mineral phosphates and silicates is compared with water circulation, plankton and seasons.
