This small project aims at preparing a large project about the Mid Pleistocene transition. I want to wash and sieve samples from the 5 ODP locations, that should be studied in the planned project, in order to find out whether enough of those benhtic foraminiferal species are available that form the basis for Caroline Lear's geochemical work (Mg/ca, Li/Ca, U/Ca). These data will contribute to the reconstruction of marine productivity besides micropaleontological studies of accumulation rates of benthic foraminifera and of stable isotopes. The planned large project will study whether an increase in marine biological productivity contributed to the drop in pCO2 atm. during the Mid Pleistocene Transition.

这个小项目旨在准备一个有关中更新世过渡的大型项目。我想对 5 个 ODP 地点的样品进行清洗和筛分，这些样品应该在计划的项目中进行研究，以便查明是否有足够的底栖有孔虫物种，为 Caroline Lear 的地球化学工作（Mg/ca、Li/Ca、U/Ca）奠定基础。除了底栖有孔虫和稳定同位素积累率的微古生物学研究之外，这些数据还将有助于海洋生产力的重建。计划中的大型项目将研究海洋生物生产力的增加是否导致了 pCO2 atm 的下降。在中更新世过渡期间。
