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探项目提供支持。该项目的目标是从中国东北部的一个主要裂谷盆地恢复整个白垩纪的基本完整的陆地沉积记录，这将为白垩纪非海洋气候提供参考，特别是温室和缺氧海洋时期。利用国内的资金来源，中国科学家已经对整个上白垩统进行了取心(约2.5公里的岩心，回收率为95%)。国际上对该核心的访问极其有限，但PI和他的美国同事已被给予足够的访问权限，以证明整个部分都有强大的C和O信号。随后，PI和他的同事获得了国际大陆钻探计划(ICDP)的拨款，对整个下白垩统进行取心。国际和平研究所及其同事在北京组织了一次为期3天的潜在合作者会议，为ICDP岩芯的科学分析制定计划。ICDP的参与保证了国际上接触核心的机会。这些参与者中有许多著名的美国科学家，他们专门从事稳定同位素、辐射测年、磁层、湖泊沉积学和古气候学。这一合作为通过白垩纪陆地信号了解全球气候历史提供了独一无二的机会，并可对当前的气候变化分析产生重要影响。

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.
