A variety of extreme climate events occurred during the period of the US GLOBEC NEP monitoring and process studies in the California Current System (CCS) (1997-2003). These provided an unprecedented opportunity to examine a wide range of climate variability experienced by the CCS and its ecosystems. By relating these climate events to regional physical and biological observations, using multiple and diverse data sources (GLOBEC and other recent observations, historical datasets, satellites, circulation and physical-biological models), the investigators will determine how these events affect mesoscale ocean variability and target populations in the CCS. The overarching goal of this project is to characterize the linkages between basin-scale variability indicative of climate events and local changes in mesoscale coastal ocean circulation and structure that impact marine populations, ecosystem structure and productivity. Correlative methods will be used initially to characterize mesoscale variability in the CCS and the concurrent basin-scale conditions during the time of the Field Program and further back where possible. Building on these correlational linkages between basin and mesoscale patterns of variability, the investigators will examine the mechanisms behind these linkages from three different points of view: comparing interannual and decadal scales of climate variability, identifying and comparing different regions of climate response in the CCS, and examining changes in the seasonal signals. From these integrative analyses, they will provide robust indicators of the response of marine populations to climate change, a useful tool for resource assessment and management. The datasets, satellite images and key metrics and indices will be served on a series of Live Access Servers (LAS) and OPeNDAP Servers, which will allow scientists, resource managers, and the public to transparently access, subset and download our data products. Some of the satellite and survey data sets will also be incorporated into curriculum material that is under development within the OSU SMILE program. These materials are used in twelve Oregon high school districts with large proportions of students from groups traditionally under-represented in university science and mathematics departments.

在美国GLOBEC NEP监测和加州海流系统（CCS）过程研究期间（1997-2003年）发生了多种极端气候事件。这为研究CCS及其生态系统所经历的各种气候变异性提供了前所未有的机会。通过将这些气候事件与区域物理和生物观测联系起来，使用多种多样的数据源（全球地球观测和其他最近的观测、历史数据集、卫星、环流和物理生物模型），调查人员将确定这些事件如何影响中尺度海洋变异性和CCS中的目标人群。 该项目的总体目标是确定表明气候事件的流域尺度变率与影响海洋种群、生态系统结构和生产力的中尺度沿海海洋环流和结构的局部变化之间的联系。 相关方法将首先用于描述CCS中的中尺度变率和现场项目期间以及可能的情况下的同期流域尺度条件。 基于流域和中尺度变化模式之间的这些相关联系，研究人员将从三个不同的角度研究这些联系背后的机制：比较年际和十年尺度的气候变率，确定和比较CCS中气候响应的不同区域，并研究季节信号的变化。 通过这些综合分析，它们将为海洋种群对气候变化的反应提供强有力的指标，这是资源评估和管理的有用工具。 数据集、卫星图像和关键指标和指数将在一系列实时访问服务器（LAS）和OPeNDAP服务器上提供，这将使科学家、资源管理者和公众能够透明地访问、子集化和下载我们的数据产品。一些卫星和调查数据集也将被纳入正在俄勒冈州立大学SMILE计划内开发的课程材料。这些材料在12个俄勒冈州高中学区使用，这些学区的学生大部分来自传统上在大学科学和数学系代表性不足的群体。
