中文摘要

这个项目将比较在onong -爪哇高原的深层样带中活的和最近死亡的(核心-顶部)底栖有孔虫标本。以往的研究表明,随着方解石深度的增加和饱和度的降低,方解石中微量金属和13C的含量有系统地减少。这些趋势可能反映了在不同饱和状态下生长过程中溶蚀或分馏的影响。效果可以通过活人/死人的比较来区分;如果没有区别,那么解散就不起作用。
英文摘要
9633588 McCorkle This project will compare live and recently-dead (core-top) specimens of epibenthic foraminifera from depth transects on the Ontong-Java Plateau. Previous work indicates a systematic decrease of incorporated trace metals and 13C with increasing depth and with decreasing saturation state of calcite. These trends could reflect either an effect of dissolution, or fractionation during growth under varying saturation state. The effects can be discriminated by live/dead comparison; if there is no different then dissolution does not play a role.
