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).

该项目采用一套数值模拟方法，研究了俄勒冈州海岸外大陆架和邻近海洋之间的环流和动力学过程。 面向过程的建模，数据分析和变分数据同化将被用来调查跨海岸过渡带的交换。 将利用广泛的现有数据集来限制数值模拟，而数值模拟又将用于调查沿海和公海之间的输送和交换。 在同化实验中将使用各种观测数据组合，以评估其效用。 该项目有可能在我们理解如何使用数据来改善沿海地区的数值模拟方面取得变革性的成果。该项目解决了有关陆架、陆坡和邻近公海环流模式的基本问题。 因此，它对海洋学的其他领域产生了间接的更广泛的影响，包括与俄勒冈州海岸低氧区有关的动态。 该项目也是该地区以前观测和建模工作的自然延伸。 这一系列模拟和同化实验与海洋观测站倡议的持续发展和最终实施高度相关。
