Interannual, Interdecadal and Centennial Climate Variability in the Eastern North Pacific Over the Past 2000 Years

摘要ATM-9406510 Cayan，丹尼尔鲍姆加特纳，蒂姆加州大学，圣地亚哥标题：在过去2000年中，北太平洋东部的年际，年代际和百年气候变率 圣巴巴拉盆地作为古气候资源正变得越来越重要。 在圣巴巴拉盆地的年度微体动物和同位素记录提供了一个机会，重建晚全新世气候的北方半球的一个重要遥相关中心。 这些记录似乎是该地区温度和其他可能的大尺度参数的代理。 该奖项支持一个由三部分组成的项目，包括：（A）开发保存在圣巴巴拉盆地的年度生物记录，作为仪器气候记录的替代;（B）将在仪器记录上建立一个北太平洋温度和环流模型，大约1900年至今;（C）利用这一模式，将对保存在圣巴巴拉盆地化石记录中的较长历史进行取样，以便重建过去2000年的区域气候。 这项研究是一个跨学科项目，涉及海洋生物研究小组和斯克里普斯海洋研究所气候研究部。

Abstract ATM-9406510 Cayan, Daniel Baumgartner, Tim University of California,San Diego Title: Interanual, Interdecadal, and Centennial Climate Variability in the Eastern North Pacific Over the Past 2000 Years The Santa Barbara Basin is becoming increasingly important as a paleoclimate resource. The annual microfaunal and isotopic record in the Santa Barbara Basin provides an opportunity to reconstruct the late Holocene climate over one of the important teleconnection centers of the northern hemisphere. The records appear to be proxies for temperature and possibly other large-scale parameters of the region. This award supports a three-part project to include: (A) develop the annual biological records preserved in the Santa Barbara Basin as proxies for the instrumental climate record; (B) a model will be constructed of the North Pacific temperature and circulation over the instrumental record, approximately 1900- present; (C) using this model, the longer history preserved in the Santa Barbara Basin fossil record will be sampled in order to reconstruct the regional climate over the past 2000 years. This research is an interdisciplinary project involving the Marine Life Research Group and the Climate Research Division of the Scripps Institution of Oceanography.
