Rudnick 9819521Funding is provided to conduct a large coordinated experiment near the Hawaiian Ridge to determine whether sites with rough topography are responsible for the mixing of the global ocean. The goals are to identify the major energy pathways for ocean mixing and achieve an approximate energy budget for the region. The SeaSoar and Acoustic Doppler Current Profiler survey alongside the Hawaiian Ridge will compile statistics of both stratification and shear to identify sites of likely intense mixing and it will use recent internal waves parameterization and estimates of vertical overturns to infer dissipation and diffusivity. Deployment of several LAgrangian Microstructure Profilers (LAMP) will help quantify thermal dissipation in both homogeneous and stratified regions of the upper 400 m of the ocean.

提供资金在夏威夷海脊附近进行一项大型协调实验，以确定地形粗糙的地点是否对全球海洋的混合负责。目标是确定海洋混合的主要能量途径，并实现该区域的大致能量收支。在夏威夷海岭附近进行的SeaSoar和Acoustic Doppler Current Profiler调查将收集分层和切变的统计数据，以确定可能发生强烈混合的地点，并将使用最近的内波参数化和垂直翻转的估计来推断耗散和扩散。几个拉格朗日微观结构剖面仪（LAMP）的部署将有助于量化海洋上层400米均匀和分层区域的热耗散。
