Travel Grant: Continental Scientific Drilling Project of Cretaceous Songliao Basin

该奖项为美国参与目前正在中国进行的白垩纪气候岩心钻孔项目提供了支持。该项目的目标是在中国东北的一个主要裂谷盆地中恢复整个白垩纪时期基本完整的陆相沉积记录，这将为白垩纪非海洋气候提供代用物，特别是温室和缺氧海洋时期。利用国内资金，中国科学家已经完成了整个上白垩纪的岩芯采集（岩芯约2.5公里，回收率为95%）。国际上对该核心的访问非常有限，但PI和他的美国同事已经获得了足够的访问权限，以证明整个部分都有强大的C和o信号。随后，PI及其同事获得了国际大陆钻井计划（ICDP）的资助，对整个下白垩纪进行了岩心采集。PI及其同事在北京组织了为期3天的可能合作者会议，为ICDP岩心孔的科学分析制定计划。ICDP的参与保证了国际上对核心的访问。在这些参与者中，有一些著名的美国科学家专门研究稳定同位素、放射性测年、磁层、湖泊沉积学和古气候学。这次合作提供了一个独一无二的机会，通过白垩纪陆地信号来了解全球气候历史，并对当前的气候变化分析具有重要意义。

This award provides support for American participation in the Cretaceous-climate corehole drilling project currently underway in China. The goal of the project is to recover an essentially complete terrestrial sedimentary record of the entire Cretaceous period from a major rift basin in northeastern China, which will provide proxies for Cretaceous nonmarine climate, with particular emphasis on greenhouse and anoxic ocean periods. Using domestic funding resources, Chinese scientists have already cored the entire Upper Cretaceous (ca 2.5 km of core, with recovery 95%). International access to that core has been extremely limited, but the PI and hisAmerican colleagues have been given sufficient access to demonstrate that there are robust C- and O-signals throughout the section. Subsequently, the PI and colleagues have obtained a grant from the International Continental Drilling Program (ICDP) to core the entire Lower Cretaceous. The PI and colleagues have organized a 3-day meeting of likely collaborators in Beijing to lay plans for the scientific analysis of the ICDP corehole. ICDP participation guarantees international access to the core. Among those participating are a number of noted American scientists specializing in stable isotopes, radiometric dating, magnetostrat, lacustrine sedimentology, and paleoclimatology. This collaboration provides a one-of-a-kind opportunity with respect to understanding global climate history through the Cretaceous terrestrial signals and can have important implications for current climate-change analyses.
