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.

该奖项为美国参与目前正在中国进行的气候恶劣的岩心钻探项目提供了支持。该项目的目标是从中国东北的一个主要裂谷盆地中恢复一个基本完整的整个白垩纪的陆地沉积记录，这将提供白垩纪非海洋气候的替代物，特别强调温室和缺氧海洋时期。利用国内资金，中国科学家已经对整个上白垩统进行了岩心采集（约2.5公里的岩心，回收率为95%）。国际上对这一核心的访问一直非常有限，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和同事们获得了国际大陆钻探计划（ICDP）的资助，对整个下白垩纪进行了岩心钻探。 PI和同事在北京组织了为期3天的可能合作者会议，为ICDP核心孔的科学分析制定计划。综合社区发展项目的参与保证了国际社会对核心资源的利用。在这些参与者中，有一些著名的美国科学家专门从事稳定同位素，放射性测年，磁层，湖泊沉积学和古气候学。这项合作提供了一个独一无二的机会，通过白垩纪陆地信号了解全球气候历史，并可能对当前的气候变化分析产生重要影响。
