The goal of the GLOBEC Northeast Pacific program is to gain an understanding of how variability in the physical environment, specifically changes that might result from climate change, affects populations of marine animals on the west coast of North America, specifically salmon and associated species. The PIs will formulate models spanning the individual level to the metapopulation level for two genera of interest to GLOBEC in the California Current System (CCS): (1) the two CCS salmon species identified by GLOBEC, coho salmon (Oncorhynchus kisutch) and chinook salmon (O. tshawytscha) and (2) Dungeness crab (Cancer magister), a species which covaries with salmon, is a significant prey of both species, and is subject to similar mesoscale circulation patterns. These models will link the different scales of variability and levels of ecological organization in the various retrospective, monitoring and process studies so that the effects of changes in the physical environment on populations can be projected.

GLOBEC东北太平洋计划的目标是了解物理环境的变化，特别是气候变化可能导致的变化，如何影响北美西海岸的海洋动物种群，特别是鲑鱼和相关物种。 PI将为加州海流系统（CCS）中GLOBEC感兴趣的两个属制定从个体水平到集合种群水平的模型：（1）GLOBEC确定的两个CCS鲑鱼物种，银鲑（Oncorhynchus kisutch）和奇努克鲑鱼（O. tshawytscha）和（2）Dungeness crab（Cancer magister），一种与鲑鱼共变的物种，是这两个物种的重要猎物，并且受到类似的中尺度环流模式的影响。 这些模型将在各种回顾、监测和过程研究中把不同的变异规模和生态组织水平联系起来，以便预测自然环境变化对人口的影响。
