"Remarkable changes in atmospheric, oceanic and biological conditions have occurred in recent decades in the North Pacific Ocean including declines in the marine survival of some salmon stocks. Fishery scientists generally agree that in the first few months after leaving freshwater, salmon survival and growth are linked to oceanic variability. The purpose of this research is to focus National Marine Fisheries Service studies on the GLOBEC region, augment oceanographic measurements and determine what biological and physical factors influence the distribution of juvenile salmon. Three general hypotheses are explored in this proposal: (1) juvenile salmon prefer the buoyancy-driven Alaska Coastal Current (ACC) at the head of the Gulf of Alaska, (2) they associate with oceanic temperature, salinity, current and prey fields, and (3) they migrate landward of Kodiak Island in the ACC rather than seaward in the Alaskan Stream. Annual, summer cruises aboard a chartered fishing vessel will catch juvenile salmon on 10 transects between Yakutat Bay and Kodiak Island. The vessel will be outfitted with a thermosalinograph to measure sea-surface temperature and salinity, and with an Acoustic Doppler Current Profiler (ADCP) - each operating continuously for fine-scale resolution. Modeled tidal currents will be removed from ADCP measurements to reveal the mean flow fields. At each trawl site, temperature and salinity profiles will provide water-column properties, and bongo-net hauls will give zooplankton distributions. Stomach samples from juvenile salmonids will be analyzed in the laboratory for diet composition and compared with zooplankton distributions. Analysis of salmon otoliths for hatchery thermal marks and Genetic Stock Identification techniques will be used to determine the home stream of hatchery and wild stocks in the Gulf of Alaska and their distribution with respect to oceanographic regimes. Retrospective analysis of catch per unit effort versus oceanographic and prey factors will reveal what affects the distribution of pink, chum, coho and sockeye salmon in the study region. Proxies for bio-physical factors will be developed and compared with salmon-run size."(project proposal)

GLOBEC 2000：影响阿拉斯加湾幼鲑分布的因素

"近数十年来，北太平洋海域的大气、海洋与生物环境发生了显著变化，部分鲑鱼种群的海洋存活率出现下降。渔业科学家普遍认为，鲑鱼在离开淡水后的最初数月内，其存活与生长与海洋环境变率密切相关。本研究旨在将美国国家海洋渔业局的研究聚焦于GLOBEC研究区域，补充海洋学观测数据，并明确哪些生物与物理因素会影响幼鲑的分布。本提案将探讨三个核心假说：（1）幼鲑偏好阿拉斯加湾头部由浮力驱动的阿拉斯加沿岸流（Alaska Coastal Current, ACC）；（2）幼鲑与海洋温度、盐度、流场及猎物分布相关联；（3）幼鲑会通过阿拉斯加沿岸流向科迪亚克岛西侧洄游，而非沿阿拉斯加海流向外海移动。2001至2004年每年的7-8月，研究团队将搭乘包租渔船开展为期约两周的夏季航次，在雅库塔特湾与科迪亚克岛之间的10条断面上采集幼鲑样本。渔船将配备走航式热盐计（thermosalinograph）以连续测量海表温度与盐度，同时搭载声学多普勒流速剖面仪（Acoustic Doppler Current Profiler, ADCP）以获取高精度的连续流场数据。研究人员将从ADCP测量数据中移除模拟潮汐流，以得到平均流场。在每个拖网采样站位，研究人员将通过温盐深剖面仪（Conductivity Temperature Depth, CTD）获取水柱环境参数，并通过邦戈网拖网采集浮游动物样本以分析其分布。研究团队将在实验室中分析幼鲑的胃含物样本，以确定其日粮组成，并与浮游动物分布进行比对。通过分析鲑鱼耳石的孵化场热标记以及采用遗传种群鉴定（Genetic Stock Identification）技术，研究人员将确定阿拉斯加湾孵化场种群与野生种群的原生溪流，并明确其与海洋环境的分布关联。通过回顾性分析单位捕捞努力量渔获量与海洋环境、猎物因素的相关性，研究人员将明确哪些因素会影响研究区域内粉鲑、大麻哈鱼、银鲑与红大马哈鱼的分布。本研究还将构建生物物理因素的替代指标，并与鲑鱼洄游种群规模进行对比分析。（项目提案）"
