The Role of Eddies in Basin Scale Biogeochemical Budgets of the North Atlantic

9725974 McGillicuddy物理-生物地球化学耦合模型提供了一个有用的框架，用于测试我们关于海洋元素循环的潜在物理、生物和化学控制的想法。到目前为止，在盆地规模上这样做的努力产生了好坏参半的结果。在这个项目中，研究人员将建立北大西洋第一个盆地尺度的涡旋分辨生物地球化学模拟，以检查中尺度过程对大尺度元素收支的影响。计划进行一系列基于1‘(粗略)、1/3(允许涡流)和1/6’(涡旋分辨)CME模拟的实验。粗分辨率运行将用于对Sarmiento和Fasham结果进行基准测试，并作为较高分辨率计算的控制运行。尽管允许涡旋的情况很可能不足以全面研究中尺度过程，但它确实代表了一个有意义的中间步骤，它将提供有用的信息，而不会招致1/6‘运行的大量计算成本。从这些实验中获得的理解将被用来指导发展中尺度生物地球化学过程的参数，以便将其纳入更大规模的(全球)模式。

9725974 McGillicuddy Coupled physical-biogeochemical models provide a useful framework for testing our ideas about the underlying physical, biological and chemical controls on elemental cycling in the ocean. Up to now, efforts to do so on basin scales have produced mixed results. In this project, the investigators will construct the first basin scale eddy-resolving biogeochemical simulations of the North Atlantic to examine the impact of mesoscale processes on large scale elemental budgets. A suite of experiments is planned what are based on 1' (coarse), 1/3 (eddy-permitting) and 1/6' (eddy- resolving) CME simulations. The coarse resolution runs will be used to benchmark the Sarmiento and Fasham results, and serve as a control run for the higher resolution calculations. Although the eddy-permitting case will most likely not be entirely sufficient for a comprehensive study of mesoscale processes, it does represent a meaningful intermediated step that will provide useful information without incurring the substantial computational cost of the 1/6' runs. Understanding gained from these experiments will be used to guide the development of parameterizations for mesoscale biogeochemical processes to permit their inclusion in larger scale (global) models.
