Modeling, Assimilation, and Analysis of the Shelf - Interior Ocean Exchange off Oregon

该项目利用一套数值模拟方法，研究了发生在俄勒冈海岸外大陆架和邻近海洋之间的环流和动力学过程。面向过程的模拟、资料分析和变分资料同化将被用来研究沿海过渡带的交换。将利用广泛的现有数据集来约束数值模拟，这些数值模拟将被用来调查沿海和公海之间的运输和交换。观测数据的各种组合将用于同化实验，以评估它们的效用。该项目有可能在我们理解如何利用数据改进沿海地区的数值模拟方面取得变革性的结果。该项目解决了有关大陆架、斜坡和邻近开阔海域的环流模式的基本问题。因此，它对海洋学的其他领域有间接的、更广泛的影响，包括与俄勒冈海岸外缺氧区有关的动力学问题。该项目也是该地区先前观测和建模工作的自然延伸。这一系列的模拟和同化实验与海洋观测站倡议(OOI)的持续发展和最终实施密切相关。

The project addresses the circulation and dynamics processes that occur between the continental shelf and adjacent ocean off the Oregon coast, using a suite of numerical modeling approaches. Process oriented modeling, data analyses, and variational data assimilation will be used to investigate the exchanges across the coastal transition zone. Use will be made of extensive, existing data sets to constrain the numerical modeling, which in turn will be used to investigate the transports and exchanges between the coastal and open ocean. Various combinations of observational data will be used in the assimilation experiments to assess their utility. The project has the potential to achieve transformative results in our understanding of how data can be used to improve numerical modeling in the coastal zone.The project addresses fundamental questions regarding the circulation patterns of the shelf, slope, and adjacent open ocean. It therefore has indirect broader impacts on other fields of oceanography including the dynamics relevant to the hypoxia zone off the Oregon coast. The project is also a natural extension of previous observational and modeling work for the region. The series of modeling and assimilation experiments are highly relevant to the ongoing development and eventual implementation of the Ocean Observatories Initiative (OOI).
