US-GLOBEC NEP Phase IIIa-CCS: Large-scale Influences on Mesoscale Structure in the CCS, A Synthesis of Climate-forced Variability in Coastal Ecosystems

在美国加州海流系统(CCS)的GLOBEC NEP监测和过程研究期间(1997-2003年)，发生了各种极端气候事件。这为审查气候系统及其生态系统所经历的各种气候变化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，利用多种不同的数据来源(GLOBEC和其他最近的观测、历史数据集、卫星、环流和物理-生物模型)，研究人员将确定这些事件如何影响CCS的中尺度海洋变异性和目标人口。该项目的总体目标是确定表明气候事件的流域尺度变化与影响海洋种群、生态系统结构和生产力的沿海中尺度海洋环流和结构的局部变化之间的联系。最初将使用相关方法来描述CCS中的中尺度变异性，以及在实地方案期间和可能的情况下的同时流域尺度条件。在流域和中尺度变率模式之间的这些相互联系的基础上，研究人员将从三个不同的角度审查这些联系背后的机制：比较气候变率的年际和年代际尺度，查明和比较中央气候系统中气候反应的不同区域，以及检查季节信号的变化。从这些综合分析中，它们将提供海洋人口对气候变化反应的有力指标，这是资源评估和管理的有用工具。数据集、卫星图像以及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、资源经理和公众能够透明地访问、子集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俄亥俄州立大学微笑方案正在开发的课程材料中。这些材料在俄勒冈州的12个高中学区使用，其中很大比例的学生来自传统上在大学科学和数学系中代表性不足的群体。

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.
