GLOBEC-01: Integration and Synthesis of the George's Bank Broad-Scale Survey Results

GLOBEC NW Atlantic/Georges Bank的研究确定了鳕鱼（Gadus morhua）和黑线鳕（Melanogrammus aegleftus）以及桡足类浮游动物Calanusfinmarchicus和Pseudocalanus spp.的远洋早期生命阶段。作为目标生物（全球生物理事会，1992年），广泛和深入地努力了解控制海洋动物主要种群在空间和时间上的种群动态的基本物理和生物过程。超过六分？在为期一年的时间里，对乔治浅滩和邻近沃茨进行了大规模调查，以收集样本，用于目标鱼类和浮游动物种群的群体和生存分析。这些调查包括收集关于水文地理、声学、浮游植物叶绿素、竞争者和捕食者以及目标物种的数据，以便描述目标物种所居住的生物和物理环境。美国GLOBEC乔治银行计划的第四阶段旨在综合该计划早期阶段的结果，以提供对关键目标物种种群动态的综合了解，并评估不同气候如何影响这些种群。这个项目的目的是利用调查数据集来解决两个首要问题：1）什么控制了内部？乔治河岸目标物种丰度的年度变化（例如，自下而上或自上而下的生物过程，或物理的平流过程）？2)这些过程可能如何受到气候变化的影响？ 这些活动和成果将为涉及GLOBEC乔治银行计划所有组成部分的完整跨学科综合提供基础。

The GLOBEC NW Atlantic/Georges Bank study identified the pelagic early life stages of cod (Gadus morhua) and haddock (Melanogrammus aegleftus) and the copepod zooplankton, Calanusfinmarchicus and Pseudocalanus spp. as target organisms (GLOBEC, 1992) for an extensive and intensive effort to understand the underlying physical and biological processes that control the population dynamics of key populations of marine animals in space and time. Over a six?year period, broad-scale surveys of the Georges Bank and adjacent waters were conducted to collect samples for cohort and survivorship analysis of the target fish and zooplankton populations. These surveys included the collection of data on hydrography, acoustics, phytoplankton chlorophyll, competitors, and predators, as well as the target species, in order to provide a description of the biological and physical environment in which the target species resided. Phase IV of the US GLOBEC Georges Bank program is designed to synthesize the results from the program's earlier phases to provide an integrated understanding of the population dynamics of key, target species and evaluate how a varying climate may influence these populations. The intent in this project is to capitalize on the survey data sets to address two overarching questions: 1) What controls inter?annual variability in the abundance of the target species on Georges Bank (e.g., bottom up or top down biological processes, or physical, advective processes)? 2) How are these processes likely to be influenced by climate variability? These activities and results will provide a fundamental foundation for a complete interdisciplinary synthesis involving all components of the GLOBEC Georges Bank program.
