Research Abstract

Chemical constituents in pore waters of sediment cores collected along latitudinal sections in the central and east equatorial Pacific were measured. On the basis of the distributions of silicate and dissolved barium in pore waters, originated from biogenic opal and barite particles, respectively, their diffusive fluxes upward from the bottom sediment were analyzed. Both of the upward fluxes were estimated to be high in the Antarctic and Equatorial and low in the subtropical regions. This can indicate that the latitudinal changes in the upward fluxes of silicate and dissolved barium result from the geographical change of biological production in the ocean.
