Latitudinal section mapping of pore water constituents in the central and eastern equatorial Pacific

对赤道太平洋中部和东部沿纬度剖面采集的沉积物岩心的孔隙水化学成分进行了测定。根据生物蛋白石和重晶石颗粒在孔隙水中的分布，分析了它们从底质向上的扩散通量。据估计，南极和赤道的向上通量都很高，而副热带地区的向上通量都很低。这表明，海洋生物生产的地理变化导致了硅酸盐和溶解钡向上通量的纬向变化。

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.
