0115357KellerDescription: This project is to support a cooperative research project by Dr. Gerta Keller, Department of Geosciences, Princeton, Princeton, New Jersey and Dr. El Hassane Chellai, Department of Geology, University of Cadi Ayyad, Marrakech, Morocco. They plan to conduct a high-resolution study of the organic carbon rich pelagic carbonates of the Cenomanaian-Turonian transition exposed along NW Atlantic margin of Morocco. The primary target will be the Cenomanaian-Turonian transition interval represented by planktic foraminiferal zones R. cushmani, W. archaeocretacea and H. helvetica, an interval that is represented by up to 160m of sediments along the Atlantic margin. This study will provide the most detailed record of these global anoxic event and greenhouse conditions and serve as analogue for a potential future greenhouse event. Scope: The PI plans to carry out a multi-institutional and multi-disciplinary study that documents the Cenomanian-Turonian anoxic event and greenhouse conditions in terms of climate, sea level and productivity fluctuations and their effect on marine plankton (e.g. planktic foraminifera and calcareous nannoplankton). This study will bring together experts in sedimentology and stratigraphy, mineralogy stable isotopes, geochemistry, calcareous nannofossils and planktic foraminifera. The project will involve graduate and undergraduate students in the field work and laboratory analyses thus exposing them to working in a foreign country. An Egyptian scientist, Dr. A. A. Tantawy from South Valley University, Aswan, Egypt will also participate in the research based on his expertise in high-resolution age and biostratigraphy. This project meets INT criteria for supporting meritorious collaborative research of mutual benefit to the US and the foreign country. This project is funded by the Division of International Programs and the Division of Earth Sciences.

0115357 KellerDescription：该项目旨在支持由新泽西州普林斯顿普林斯顿地质科学系Gerta Keller博士和摩洛哥马拉喀什Cadi Ayyad大学地质学系El Hassane Cherlai博士开展的合作研究项目。他们计划对摩洛哥西北大西洋边缘Cenomanaian-Turonia过渡时期暴露的富含有机碳的远洋碳酸盐进行高分辨率研究。主要目标将是Cenomanaian-Turonia过渡区间，以浮游有孔虫区域R.cushmani、W.考古考古动物和H.Helvetica为代表，该区间由大西洋边缘多达160米的沉积物表示。这项研究将提供这些全球缺氧事件和温室条件的最详细记录，并作为未来潜在温室事件的类比。范围：国际海洋研究所计划开展一项多机构和多学科的研究，从气候、海平面和生产力波动及其对海洋浮游生物(例如浮游性有孔虫和钙质超微浮游生物)的影响等方面记录塞诺马尼亚-图罗尼亚缺氧事件和温室条件。这项研究将汇集沉积学和地层学、矿物学稳定同位素、地球化学、钙质超微化石和浮游有孔虫的专家。该项目将让研究生和本科生参与实地工作和实验室分析，从而使他们有机会在外国工作。来自埃及阿斯旺南谷大学的埃及科学家A·A·坦塔维博士也将参与这项研究，他在高分辨率测年和生物地层学方面的专业知识。该项目符合INT标准，支持对美国和外国互惠互利的有价值的合作研究。该项目由国际项目部和地球科学部资助。
