Dynamics of Steep Sided Coastal Sumbmarine Canyons

OCE 9618293克林克 该项目的目标是获得一个动态的了解陡峭的峡谷内的循环和水的属性变化。还将研究峡谷与沿海环流的相互作用。一个三阶段的方法将被使用，结合现场观察，数值模拟和实验室实验。现有的观测结果将进一步分析，并用于模型和实验室模拟的初始化。 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，流的依赖强迫机制，和潮汐效应。

OCE 9618293 Klinck 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.
