Collaborative Research: U.S. GLOBEC: Importance of Physical and Biological Processes to Population Regulation of Cod and Haddock on Georges Bank: A Model-Based Study

9632758林奇该项目是美国GLOBEC西北大西洋实地研究第二阶段计划的一部分，是对乔治斯浅滩和邻近大陆架进行的特定地点生物物理模拟研究的继续。该项目将使用达特茅斯有限元模型来调查乔治斯海岸和邻近大陆架地区的水循环和运输。以个体为基础的鱼类早期生命阶段模型将包括湍流、分层和摄食的作用。还将对MARMAP和GLOBEC数据进行回溯性研究，以检查整个大陆架和年际/年代尺度。对历史浮游动物分布的模拟分析将讨论缅因湾和斯科特大陆架作为乔治斯海岸种群来源的相对重要性。该项目包括一个系泊现场部分，用于测量流入乔治斯银行/缅因湾系统的主要流量。这些调查将与拟议的加拿大GLOBEC关于斯科特大陆架的研究密切协调。***

9632758 LYNCH This project represents a continuation of a site-specific biophysical modeling study of Georges Bank and the adjacent shelf as part of the U.S. GLOBEC Northwest Atlantic Field Studies, Phase 2 program. The project will use the Dartmouth finite element models to investigate water circulation and transport on Georges Bank and adjacent shelf areas. Individual-based models of early life stages of fishes will incorporate the role of turbulence, stratification and feeding. Retrospective studies of MARMAP and GLOBEC data will also be conducted to examine shelf-wide and interannual/decadal scales. Modeling analysis of historical zooplankton distributions will address the relative importance of the Gulf of Maine and Scotian Shelf as sources of Georges Bank populations. A moored field component is included in this project to measure the key inflows to the Georges Bank/Gulf of Maine system. The investigations will be closely coordinated with the proposed Canada GLOBEC studies on the Scotian Shelf. ***
