Summary: Based on data from Leg 138 of the D/V Joides Resolution, the possibility of some paleoceanological reconstructions taking into account concentrations and absolute masses of biogenic SiO2 is considered. The principal possibility of reconstruction of the history of silica accumulation in the Miocene-Quaternary is shown. Absolute masses of Ba are proposed to use in order to obtain data on the evolution of paleoproductivity.
