The 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.

该研究解决了一个总体问题：海洋食品网是从自上而下的，自下而上的还是两者的组合来控制渔业的海洋食物网？为了解决这个问题，我们将（1）在自上而下的诉自下而上的强迫案中比较4个美国 - 格洛贝克研究区域的端到端能源预算，（2）评估区域模型捕获基本材料磁通量的技能，（3）从区域模型中提取诊断，这些诊断将用于评估跨越全球压力范围的效果，以评估全球范围的效果，并（4）进行诊断和（4）方法。 Globec的主要成功是阐明以各种物理环境为特征的生态系统中各种物种动态的过程。同时，对生态系统的管理方法的需求不断增长，以管理捕鱼压力和气候变化的海洋资源管理。提高对海洋食品网中营养环节的理解是理解和预测生态系统对气候变化和人为强迫的反应的能力的重要性。与数据组装和分析结合的最先进的建模方法的使用为培训研究生（包括3个项目中的3个）（包括3个）（食品网络建模，数据分析，数据同化，海洋生态学）提供了机会，以解决海洋系统面临的重要科学和社会问题。该项目包括2位博士后科学家，许多女性（22名调查人员中的9名），其中包括几个铅角色，几位新手Globec的年轻科学家，Globec的其他科学家以及一个杰出的国际合作者团队（请参阅BAS的支持信）。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是有益的。通过面对面，数字和电子会议通过密集，频繁沟通的管理计划是该项目的独特且潜在的变革方面。
