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

Whitlock, Cathy W.标题：太平洋西北地区对过去15万年大规模气候变化的响应该奖项支持对过去150万年太平洋西北地区古气候历史的研究，并研究过去气候变化的原因。这项研究是基于在过去20年中控制气候变化的大规模控制与这些控制在特定地区的影响之间的新关系。这些关系可以产生假设，描述过去150年中各种控制因素的不同组合如何控制区域古气候响应。这些假设将使用本研究中获得的长期记录进行检验。这次调查的结果将：-记录过去150年来太平洋西北地区的古气候历史；-阐明区域古气候变化的大尺度控制因素；-澄清末次冰期-间冰期旋回中断的突发气候事件的性质和程度；提供关键的陆地-海洋比较，这将有助于揭示太平洋西北地区大气和海洋环流、水文和生物群之间的长期相互作用
