项目摘要
Section profile of dissolved barium along the Arabian Sea to the Antarctic Ocean in the western Indian Ocean region covering the entire water depth was investigated through the Japanese-GEOTRACES study. In the barium vs silicate/nitratediagram, there shows the linear relationship between barium and silicate/nitrate ratio, and the slope is almost equal to that obtained in the Eastern Indian Ocean. Vertical distributions of barium in pore waters in sediment cores from the same transect were also measured. Particularly, in the Arabian Sea where higher bariumconcentrations in the bottom water were obtained, pore water barium concentrations in the top few cm were very much higher than the solubility of barite. It is suggested that the upward diffusive flux of barium beyond the sediment-water interface due to this concentration difference between in the bottom and pore waters maintain the higher bariumbottom water in the Arabian Sea.
通过日本-GEOTRACES研究,调查了西印度洋区域沿阿拉伯海沿着至南极洋整个水深的溶解钡剖面。在钡-硅酸盐/硝酸盐关系图中,钡与硅酸盐/硝酸盐比值呈线性关系,其斜率与东印度洋的结果基本一致。同时还测定了同一断面沉积物柱样孔隙沃茨中钡的垂直分布。特别是在阿拉伯海,在底层水中获得了较高的钡浓度,在顶部几厘米的孔隙水钡浓度远远高于重晶石的溶解度。这表明,由于底层水和孔隙水沃茨之间的这种浓度差,钡在沉积物-水界面外的向上扩散通量维持了阿拉伯海较高的钡底层水。
