9634165 INCZE Recent studies indicate that interannual differences in circulation processes can substantially impact retention and recruitment of fish eggs and larvae on Georges Bank. Strong year classes of cod and haddock are hypothesized to be associated with a relatively high degree of retention on the Bank. This project will undertake an interdisciplinary field study along the southern flank of Georges Bank, as part of the U.S. GLOBEC Northwest Atlantic Field Studies Phase II program, to clarify the relative importance of dispersive and advective processes affecting retention/loss, feeding, growth rates and nutritional conditions of larval cod and haddock. The project implements a three-dimensional circulation model that will be used in near real-time to conduct the field program. A hindcasting model will be utilized to integrate physical and biological observations in coupled circulation-trophodynamic simulations. ***

9634165发现最近的研究表明，循环过程的年际差异可以显着影响乔治银行上鱼卵和幼虫的保留率和募集。 假设年纪强的鳕鱼和黑线径与银行的保留程度相对较高。 该项目将在乔治银行（Georges Bank）南侧进行一项跨学科的现场研究，这是美国环球西北大西洋现场研究阶段II阶段计划的一部分，以阐明影响保留率/损失，进食，增长速度和幼虫鳕鱼和幼体营养条件的分散和对流过程的相对重要性。该项目实施了三维循环模型，该模型将在近实时使用以进行现场计划。将使用后播模型来整合耦合的循环 - 营养动力学模拟中的物理和生物学观察结果。 ***
