The proposed research addresses the overarching question: are marine food webs leading to fisheries controlled from the top-down, the bottom up, or a combination of the two? To address this question we will (1) compare end-to-end energy budgets of the 4 US-GLOBEC study regions in the context of top-down v. bottom-up forcing, (2) assess the skills of the regional models in capturing basic material fluxes, (3) extract diagnostics from the regional models that will be used to evaluate the effects of climate change and fishing pressure across GLOBEC regions and (4) develop quantitative methods to compare the diagnostics. The major successes of GLOBEC have been in elucidating the processes underlying the dynamics of individual species in ecosystems characterized by diverse physical settings. At the same time there is an increasing demand for an ecosystem approach to management of marine resources subject to fishing pressures and climatic changes. Improving the understanding of trophic links in oceanic food webs is integral to the ability to understand and predict ecosystem responses to climate change and anthropogenic forcings. The use of state-of-the-art modeling approaches coupled to data assembly and analyses provides opportunities to train graduate students (3 included in project) in a variety of disciplines (food web modeling, data analyses, data assimilation, marine ecology) that are needed to address the important scientific and societal problems facing marine systems. The project includes 2 postdoctoral scientists, many women (9 of 22 investigators) including several in lead roles, several talented young scientists new to GLOBEC, other scientists new to GLOBEC, and an outstanding team of international collaborators (see Letter of Support from BAS). The cooperative effort among scientists from academia, government, and private industry is beneficial to all groups. The management plan centered on intensive, frequent communication via in-person, digital and electronic meetings is a unique and potentially transformative aspect of the project.

这项拟议的研究解决了一个首要问题：导致渔业的海洋食物网是自上而下、自下而上地控制的，还是两者的组合？为了解决这个问题，我们将(1)在自上而下与自下而上强迫的情况下比较4个美国-GLOBEC研究区的端到端能源预算，(2)评估区域模式在捕捉基本物质通量方面的技能，(3)从区域模式中提取诊断信息，用于评估气候变化和GLOBEC区域捕捞压力的影响，以及(4)开发定量方法来比较诊断结果。GLOBEC的主要成功在于阐明了以不同物理环境为特征的生态系统中个体物种动态的基本过程。与此同时，对以生态系统办法管理受捕捞压力和气候变化影响的海洋资源的需求日益增加。提高对海洋食物网中营养联系的了解，对于了解和预测生态系统对气候变化和人为强迫的反应是不可或缺的。使用最先进的建模方法，结合数据汇编和分析，提供了在各种学科(食物网建模、数据分析、数据同化、海洋生态学)方面培训研究生(包括项目中的3名)的机会，这些学科是解决海洋系统面临的重要科学和社会问题所必需的。该项目包括2名博士后科学家，许多女性(22名研究人员中的9名)，包括几名牵头人员，几名新接触GLOBEC的有才华的年轻科学家，其他刚接触GLOBEC的科学家，以及一支杰出的国际合作者团队(见BAS的支持函)。来自学术界、政府和私营企业的科学家之间的合作努力对所有群体都有利。管理计划的核心是通过面对面、数字和电子会议进行密集、频繁的沟通，这是该项目的一个独特且具有潜在变革性的方面。
