The Bighorn Basin Coring Project (BBCP) Phase I: Workshop; Northwest College, Powell, WY; Summer 2007

该提案将资助2007年夏天在怀俄明州鲍威尔举行的为期4天的研讨会，讨论大角盆地早古近纪（古新世至始新世早期）沉积物取芯的科学、后勤和行政框架。大约35名科学家、学生和行业代表将参加。讲习班还将讨论推动钻探后研究的重要问题，将通过单独的提案寻求资助。知识价值：古新世-始新世热最大值（PETM），（以及更多新发现的模仿深海岩心中观察到的PETM的小振幅碳同位素偏移），作为世界上最完整的早古近纪大陆层序，在比格霍恩盆地保存得非常完好。盆地沉积层厚约50 m。这种早古近纪地层记录的岩心将有可能开发高分辨率（1000 - 10000年采样间隔）的温度（氧同位素）、碳循环（碳同位素）和来自未风化物质的生物变化（如花粉）的代用记录，以前所未有的方式研究温室条件下大陆沉积系统的高频气候和生物变异。这将是在大陆背景下从这个间隔中恢复的唯一科学核心。更广泛的影响：拟议的与会者名单包括来自学术界、工业界和外国科学家的学生和代表。这次活动将刺激不同群体之间的互动，并将汇集地球化学家、地质年代学家、地层学家和古生物学家。提案人很清楚像Earthtime和Geosystems这样的努力，并将投入一些议程时间来讨论公众参与的外展策略。

This proposal would fund a 4-day workshop in Powell, Wyoming during the summer of 2007 to discuss the scientific, logistical, and administrative framework for coring the early Paleogene (Paleocene to early Eocene) deposits of the Bighorn Basin. Approximately 35 scientists, students, and industry representatives would take part. The workshop will also discuss the important questions driving the post-drilling research, funding for which would be sought through separate proposals. Intellectual Merit: The Paleocene-Eocene Thermal Maximum (PETM), (as well as the more newly discovered small amplitude carbon isotope excursions that mimic the PETM observed in deep-sea cores), is extremely well preserved in the Bighorn Basin as the most complete early Paleogene continental sequence in the world. The basin sediments include a ~50 meter thick PETM interval. Cores of this early Paleogene stratigraphic record would make it possible to develop high resolution (1,000-10,000 year sampling interval) proxy records for temperature (oxygen isotopes), carbon cycling (carbon isotopes), and biotic change (e.g. pollen) from unweathered material to investigate, in an unprecedented way, the high-frequency climatic and biotic variability of a continental depositional system during greenhouse conditions. This would be the only scientific core recovered from this interval in a continental setting. Broader Impacts: The proposed attendee list includes students and representatives from academia, industry, and foreign scientists. The event will stimulate interaction between different communities, and will bring together geochemists, geochronoogists, stratigraphers and paleontologists. The proposers are well aware of efforts like Earthtime and Geosystems, and will devote some agenda time to discussing outreach strategies for public engagement.
