Ocean mixing

加拿大毗邻太平洋、北冰洋和大西洋三个海岸，因此了解它们对该国的商业和福祉至关重要。海洋混合在控制经向温盐翻转环流(全球传送带)方面发挥着关键作用，该环流以1000年S的气候时间尺度运行，向阳光充足的表层水域提供营养物质，以及溶解或悬浮在海水中的天然和人为物质的扩散。在分层的开阔海洋内部，湍流主要由内部重力波的破裂控制，并似乎集中在海洋边界。除了以过程为导向收集和解释实地数据外，还将分析WOCE水文学和Argo Float等公共领域数据集，以评估混合在世界海洋中的作用。我的团队将继续研究由FineScale内波及其产生的产品产生的湍流的物理，重点是流动/地形相互作用以及内波与低频洋流的相互作用。我们还在发展染料释放和跟踪能力，以便跟踪水、污染物的扩散，并探索水在海洋中的运输和混合路径，重点是沿海环境、海底峡谷、大陆坡和陆架。

Canada is bounded on three coasts by the Pacific, Arctic and Atlantic Oceans, making understanding them vital for the country's commerce and well-being. Ocean mixing plays a critical role in controlling the meridional thermohaline overturning circulation (global conveyor belt) which operates on climatological timescales of 1000's of years, nutrient supply to sunlit surface waters, and dispersal of natural and anthropogenic materials dissolved or suspended in seawater. In the stratified open ocean interior, turbulence is largely controlled by breaking of internal gravity waves and appears to be concentrated on ocean boundaries. As well as process-oriented collection and interpretation of field data, public-domain data sets such as WOCE hydrography and ARGO float will be analyzed to assess the role of mixing in the world ocean. My group will continue to study the physics of turbulence production by finescale internal waves and the resulting products, focusing on flow/topography interactions as well as interactions of internal waves with lower-frequency currents. We are also developing dye-release and -tracking abilities in order to follow water, dispersal of contaminants and explore the pathways of water transport and mixing in the ocean with an emphasis on the coastal environment, submarine canyons, the continental slope and shelf.
