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

Cayan, Daniel Baumgartner, Tim University of California，San Diego题目：过去2000年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一个古气候资源变得越来越重要。圣巴巴拉盆地的年度微动物和同位素记录为重建北半球重要的遥相关中心之一的晚全新世气候提供了机会。这些记录似乎是该地区温度和其他大尺度参数的代用物。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品；(B)将建立一个仪器记录的1900年至今的北太平洋温度和环流模式；(C)利用该模型，将对圣巴巴拉盆地化石记录中保存的较长历史进行采样，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，涉及斯克里普斯海洋学研究所的海洋生物研究小组和气候研究部。

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.
