This award will provide funds to investigate the magnitude of the deglacial deep-sea carbonate preservation maximum with a multi-proxy approach that includes a new bulk sediment calcite dissolution proxy, the menardii fragmentation index (MFI), and multiple cores from the Pacific and Indian Oceans. Specifically, the PI will apply the MFI to deep sea sediments in an attempt to explain why a preservation spike is not seen with the MFI relative to other proxies. Results of this work will provide a significant test of hypotheses that link the deglacial rise in atmospheric CO2 to increased ventilation of deep water masses. Broader Impacts include undergraduate involvement in both research activities and the scientific and public dissemination of results as well as public outreach events such as activities for Super Science Saturday, postings on www.realclimate.org and annual student presentations at Student Scholarship Day. This project also brings together collaborators from premier research institutions and a primarily undergraduate teaching institution.

该奖项将提供资金，以调查冰消期深海碳酸盐保存最大值的大小，采用多代理方法，包括新的散装沉积物方解石溶解代理，menardii碎裂指数（MFI）以及来自太平洋和印度洋的多个岩心。具体而言，PI将把MFI应用于深海沉积物，试图解释为什么MFI相对于其他代用指标没有出现保存峰值。 这项工作的结果将提供一个重要的假设，连接大气中的CO2增加通风的深水质量的冰消上升测试。更广泛的影响包括本科生参与研究活动和结果的科学和公共传播，以及公共宣传活动，如超级科学星期六的活动，在www.realclimate.org上的帖子和学生奖学金日的年度学生演讲。该项目还汇集了来自一流研究机构和主要本科教学机构的合作者。
