Trace element contents in different types of recent bottom sediments from the Indian Ocean

Trace element contents in different types of recent botoom sediments of the Indian Ocean are given. Sediment samples were obtained during cruises of the P.P. Shirshov Institute of Oceanology, Moscow.

(Table 1) Concentrations of dissolved organic carbon and phosphates in southern tropical waters of the Indian Ocean

Determinations of dissolved organic carbon and salinity were made in a region of the subtropical convergence of southern tropical waters of the Indian Ocean. It is shown that nature of vertical distribution of dissolved organic carbon together with salinity reflects water subsiding.
