Maastrichtian and Paleocene-Eocene Environmental Changes in the Tethys Region of Tunisia, US-Tunisia Cooperative Research

产品描述：该项目支持普林斯顿大学地质和地球物理科学系Gerta Keller博士与突尼斯大学理学院地质系Dalila Zaghbib-Turki博士之间的合作。 该项目旨在研究突尼斯扩大的高沉积记录中的古新世-始新世（P-E）最大变暖和马斯特里赫特最大降温，以提供边缘特提斯的记录，从而可以测试当前的气候变化情景。 分析方法将包括高分辨率生物地层学、底栖和南极有孔虫变化的定量评估、底栖和南极有孔虫的稳定同位素分析以及粘土矿物分析。 适用范围：该项目允许一项合作活动，为美国团队提供一些最连续的P-E和马斯特里赫特低纬度部分，并允许突尼斯团队使用普林斯顿大学的实验室设施。 该项目加强了合作科学以及博士后和研究生的培训，并为科学界提供了一个重要的数据库，用于测试有关P-E温室变暖和马斯特里赫特冰川作用的各种假设。 该项目符合国际项目司的目标，即在专业知识和能力互补的情况下，将美国科学家与外国科学家联系起来，并且该项目可以导致长期合作和互利的结果。

Description: This project supports cooperation between Dr. Gerta Keller, Department of Geological and Geophysical Sciences, Princeton University, and Dr. Dalila Zaghbib-Turki, Department of Geology, Faculty of Science at the University of Tunis. The project is to study the Paleocene-Eocene (P-E) maximum warming and the Maastrichtian maximum cooling in the expanded high sedimentation records of Tunisia, in order to provide a record from the marginal Tethys that allows testing of current climate change scenarios. Analytical methods will include high resolution biostratigraphy, quantitative assessment of benthic and planktic foraminiferal changes, and stable isotopic analysis of benthic and planktic foraminifera and clay mineral analysis. Scope: This project allows a cooperative activity that provides the US team access to some of the most continuous P-E and Maastrichtian low-latitude sections, and allows the Tunisian Team access to laboratory facilities at Princeton University. The project enhances cooperative science and the training of post-docs and graduate students, and provides the scientific community with a critical database for testing various hypotheses regarding the P-E greenhouse warming and Maastrictian glaciation. The project meets the objectives of the Division of International Programs in linking US scientists with foreign scientists when the expertise and capabilities are complementary, and where the project could lead to long term collaboration and to mutually beneficial results.
