Kettler OPP 9527070 Abstract This award supports organic geochemical characterization of Cretaceous-Paleogene sedimentary rocks that are expected to be recovered during the Cape Roberts Project (CRP). The CRP proposes to core four 500 m holes from a fast ice drilling platform in the Ross Sea in 1995 and 1996. The core recovered will be described, curated, and sampled for scientific research. The CRP has the potential to answer significant questions regarding the history of the West Antarctic rift system, the development of continental ice sheets in Antarctica during the Cretaceous and Paleogene, and the response of biota to climatic deterioration and the development of seaways. Organic geochemical measurements are relevant to these issues and so are included in the initial core characterization studies. The work supported here includes measurement of whole-rock carbonate carbon, total carbon, total nitrogen, and total sulfur, analysis of the elemental composition of kerogen in selected samples, and gas chromatographic analysis of the solvent-soluble organic matter in selected samples. These data will be collected in the Crary Science and Engineering Center (CSEC) at McMurdo Station and will be reported as part of the initial core characterization study of the CRP.

Kettler OPP 9527070摘要该奖项支持白垩纪-古近纪沉积岩的有机地球化学表征，这些沉积岩预计将在罗伯茨角项目期间被发现。中央气象局计划于1995年和1996年在罗斯海的一个快速冰钻平台上钻出四个500米长的孔。将对回收的岩心进行描述、整理和取样，以便进行科学研究。CRP有可能回答有关西南极裂谷系统的历史、白垩纪和古近纪期间南极大陆冰盖的发育以及生物群对气候恶化和海道发育的反应等重大问题。有机地球化学测量与这些问题有关，因此包括在最初的岩心特征研究中。所支持的工作包括全岩碳酸盐碳、总碳、总氮和总硫的测定，所选样品中干酪根元素组成的分析，以及所选样品中可溶有机物的气相色谱分析。这些数据将在麦克默多站的CRARY科学与工程中心(CSEC)收集，并将作为CRP初始核心特征研究的一部分进行报告。
