| In the region of South-Atlantic anticyclonic circulation total concentration of zinc and copper in oceanic water ranged within 1.5-17 and 1.8-6.2 mg/l, respectively. The concentration of dissolved mineral zinc varied from 0.0 to 5.8 mg/l, that of dissolved mineral copper - from 0.0 to 2.2 mg/l, that of dissolved organic complex of zinc and of copper - within 0.4-3.6 mg/l and 0.3-1.1 mg/l, respectively. Particulate zinc ranged within 0.18-1.25 mg/l and copper within 0.22 to 3.6 mg/l. Concentration of trace elements in water and their forms ratio depended on regional hydrological conditions. Concentration of zinc in oceanic plankton varied from 3.6 to 124.6 mg/kg, that of copper and manganese - within 1.0-27.4 and 0.2-6.7 mg/kg (wet mass), respectively,... |

| Water, suspension and total plankton were sampled in the summer of 1978 from different horizons and at different time of a day in three test grounds of the Indian Ocean tropical zone. In the surface waters zinc amount varies at different time of a day. The ratio of zinc forms also changes in different horizons and at different time of a day. In the region of the ist test ground notable for the most stable hydrological characteristics the content of all zinc forms rises with depths. Maximum quantities of suspended forms of trace elements are confined to layers of elevated turbidity. Zinc, copper and manganese concentrations in the suspension are within the limits of 0.10-0.89; 0.05-7.72; 0.10-1.68 microg/mg. The trace element content in plankton samples is... |
