摘要ATM-9307201 Whitlock，Cathy W. 太平洋西北部对过去15万年来大规模气候变化的响应 该奖项支持过去150 kyr期间太平洋西北部古气候历史的研究，并检查过去气候变化的原因。 这项研究是基于在过去20 kyr期间控制气候变化的大规模控制措施与这些控制措施在特定区域内的影响之间的新兴关系。 这些关系允许假设，以描述如何在过去的150 kyr控制的变化组合可能已支配区域古气候响应。 将使用本研究中获得的长记录对假设进行检验。 调查结果将： - 记录太平洋西北部的古气候历史 最后150 kyr; - 阐明负责区域性的大规模控制 古气候变化; - 阐明突发气候事件的性质和程度， 中断了最后一次冰期-间冰期循环; - 提供关键的海陆对比， 揭示大气和大气之间的长期相互作用， 太平洋的海洋环流、水文和生物区系 西北

Abstract ATM-9307201 Whitlock, Cathy W. Title: Response of the Pacific Northwest to Large-scale Changes in Climate during the Last 150,000 Years This award supports a study of the paleoclimatic history of the Pacific Northwest during the last 150 kyr and to examine the causes of past climatic change. The research is based on the emerging relationships between the large-scale controls that governed climatic variations during the last 20 kyr and the effect of those controls within a particular region. These relationships allow hypotheses to be generated that describe how the varying combination of controls over the last 150 kyr may have governed regional paleoclimatic responses. The hypotheses will be tested using the long records obtained in this study. The results of this investigation will: - document the paleoclimatic history of the Pacific Northwest of the last 150 kyr; - elucidate the large-scale controls responsible for regional paleoclimatic variations; - clarify the nature and extent of abrupt climatic events that punctuated the last glacial-interglacial cycle; and - provide critical land-sea comparisons that will help disclose the long-term interactions among atmospheric and oceanic circulation, hydrology, and biota in the Pacific Northwest
