0217921KellerDescription:This award is for support of a joint research project by Dr. Gerta Keller, Department of Geosciences, Princeton University, Princeton, New Jersey, Dr. Ahmed Kassab, Geology Department at Assiut University, Assiut, Egypt and Dr. Abdel Aziz Tantawy, Geology Department at South Valley University, Aswan, Egypt. They plan to study the Cenomanian-Turonian (C-T) anoxic event across different bathymetric settings along the Gulf of Suez and Sinai in Egypt. The investigators plan to investigate these different bathymetric settings in Egypt and the Sinai based on a high-resolution study of the organic carbon-rich facies in a series of sections along the Gulf of Suez and in the Sinai. The study will be based on an integrated multidisciplinary approach that includes sedimentology, mineralogy, geochemistry, stable carbon and oxygen isotopes and microfossil and macrofossil biostratigraphies. The results are expected to yield critical information on the nature of organic carbon accumulation in variable settings, the biotic response of marine plankton to this crisis, and the climatic and sea level history of the region. The investigators expect to develop high-resolution biostratigraphic records that permit evaluation of the timing of the anoxic event and comparison and correlation with black shale deposition elsewhere in the Tethys.Scope:The C-T transition marks a major greenhouse warming accompanied by global ocean anoxia that was detrimental to marine benthic and planktic organisms. The resulting organic-rich facies are widespread globally and occur in a wide range of bathymetric settings with the thickest deposits with greatest source rock potential generally occur in outer-shelf environments of the low latitude Atlantic and Mediterranean Tethys. The eastern Tethys, and Egypt in particular, provides an ideal area for the study of the C-T anoxic event across different bathymetric settings from shallow shelf to deep basins, as observed in a series of dysoxic basins along the Gulf of Suez and Sinai in Egypt. This project will bring together an international team of experts in sedimentology, mineralogy, stratigraphy, stable isotopes, geochemistry and biology. At the same time the project will involve U.S. and Egyptian graduate and undergraduate students in the field and laboratory investigations and thereby introduce them to various Earth Science disciplines and expose them to working within a larger investigative team and in a foreign country. The project is funded by the Office of International Science and Engineering and the Division of Earth Sciences.

0217921 Keller描述：该奖项是为了支持一个联合研究项目，该项目由新泽西普林斯顿大学地球科学系的Gerta Keller博士、埃及艾斯尤特大学地质系的Ahmed卡萨布博士和埃及阿斯旺南谷大学地质系的Abdel Aziz Tantawy博士共同完成。 他们计划在埃及苏伊士湾和西奈半岛沿着不同的水深环境中研究塞诺曼-图伦（C-T）缺氧事件。 调查人员计划根据对苏伊士湾和西奈半岛沿着一系列剖面中富含有机碳相的高分辨率研究，调查埃及和西奈半岛这些不同的水深环境。这项研究将以综合多学科方法为基础，包括沉积学、矿物学、地球化学、稳定碳和氧同位素以及微化石和宏化石生物地层学。预计这些结果将产生关于可变环境中有机碳积累的性质、海洋浮游生物对这一危机的生物反应以及该区域的气候和海平面历史的重要信息。调查人员希望开发高分辨率的生物地层记录，允许评估缺氧事件的时间和比较和相关性与黑色页岩沉积在Tethys.Scope的其他地方：C-T过渡标志着一个重大的温室效应变暖伴随着全球海洋缺氧，是有害的海洋底栖生物和浮游生物。由此产生的富含有机相在全球范围内广泛分布，并出现在广泛的水深环境中，具有最大源岩潜力的最厚沉积物通常出现在低纬度大西洋和地中海特提斯的外陆架环境中。 东特提斯，特别是埃及，提供了一个理想的地区，从浅陆棚到深盆地的不同水深设置的C-T缺氧事件的研究，在一系列的dysopathic盆地沿着埃及的苏伊士湾和西奈半岛。该项目将汇集一个沉积学、矿物学、地层学、稳定同位素、地球化学和生物学方面的国际专家小组。与此同时，该项目将涉及美国和埃及的研究生和本科生在现场和实验室调查，从而向他们介绍各种地球科学学科，并使他们接触到一个更大的调查团队和在国外工作。 该项目由国际科学和工程处以及地球科学司资助。
