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 Incze最近的研究表明，循环过程的年际差异会对乔治斯海岸的鱼卵和幼体的留存和补充产生重大影响。假设鳕鱼和黑线鳕的年份类别较强，与银行的留存程度相对较高有关。作为美国GLOBEC西北大西洋野外研究第二阶段计划的一部分，该项目将在乔治斯浅滩南侧进行一项跨学科的实地研究，以阐明影响鳕鱼和黑线鳕幼体的滞留/损失、摄食、生长速度和营养条件的弥散和平流过程的相对重要性。该项目实施了一个三维环流模型，该模型将被近乎实时地用于进行实地方案。将利用后向预报模式在耦合的环流-营养动力学模拟中综合物理和生物观测。***
