Understanding the effects of environmental variability on salmon habitat quality is important to evaluating salmon growth and survival of listed, threatened and endangered stocks of salmonids in the Pacific Northwest. The objectives of this research are to 1) identify the physical and biological characteristics of the habitats of juvenile Chinook and coho salmon in the northern California Current, 2) develop a spatially explicit individually-based model that links salmon growth to habitat quality, and 3) develop salmon ocean habitat indices to provide annual predictions of salmon stock abundance, and indicators of climate forced ecological changes that predict interannual variations in the survival of salmonids. The investigators will determine if distribution and abundance (resource metrics), and growth and health characteristics (performance metrics) of juvenile Chinook and coho salmon during the first summer and early fall of ocean residence are affected by the interaction of physical and biological oceanographic processes which create and modulate their habitat in the California Current. The investigators will combine and synthesize 12 years of data on the ecology of juvenile salmonids derived from a) the GLOBEC California Current studies in 2000 and 2002, b) Bonneville Power Administration (BPA) studies from 1998 through 2004, and c) the Pearcy studies of 1981-1985. The knowledge developed from this research will be provided to resource managers so that harvest quotas for salmonid stocks can be set within the context of knowledge of variability in ocean conditions. Training for a graduate student and involving undergraduate students as part of an REU program at the Hatfield Marine Science Center are incorporated into the project.

了解环境变化对鲑鱼栖息地质量的影响，是重要的评估鲑鱼生长和生存的上市，受威胁和濒危的鲑鱼种群在太平洋西北部。本研究的目标是：1）确定北方加州海流中奇努克鲑鱼和银鲑幼鱼栖息地的物理和生物学特征，2）开发一个空间上明确的基于个体的模型，将鲑鱼生长与栖息地质量联系起来，3）开发鲑鱼海洋栖息地指数，以提供鲑鱼种群丰度的年度预测，以及气候强迫生态变化的指标，这些指标预测了鲑鱼生存的年际变化。 调查人员将确定是否分布和丰度（资源指标），以及青少年奇努克和银鲑的生长和健康特征（性能指标）在第一个夏天和初秋的海洋居住的物理和生物海洋学过程的相互作用，创造和调节他们的栖息地在加州电流的影响。 研究人员将联合收割机和综合12年来的数据，从一个）GLOBEC加州目前的研究在2000年和2002年，B）博纳维尔电力管理局（BPA）的研究，从1998年到2004年，和c）1981年至1985年的皮尔西研究。 从这项研究中获得的知识将提供给资源管理人员，以便在了解海洋条件变化的情况下确定鲑鱼种群的捕捞配额。 培训研究生和参与本科生作为一个在哈特菲尔德海洋科学中心的REU计划的一部分被纳入该项目。
