OCE 9618186 Hickey The objectives of the project are to obtain a dynamical understanding of the circulation and water property variations within steep sided canyons. Interaction of canyons with the coastal circulation will also be investigated. A three-phase approach will be used, combining field observations, numerical modeling, and laboratory experiments. Existing observations will be further analyzed and used for initialization of model and lab simulations. Simulations will concentrate on Astoria Canyon, where the most extensive data exist. The principal issues to be addressed are the relative importance of various flow regimes, the dependence of the flow on forcing mechanisms, and tidal effects.

该项目的目标是获得对陡峭峡谷内循环和水性质变化的动态理解。峡谷与海岸环流的相互作用也将被研究。将采用三阶段方法，结合实地观测、数值模拟和实验室实验。现有观测结果将进一步分析并用于模型初始化和实验室模拟。模拟将集中在阿斯托里亚峡谷，那里有最广泛的数据。要解决的主要问题是各种流态的相对重要性、流对强迫机制的依赖以及潮汐效应。
