Hawaii Ocean Mixing Experiment: Nearfield Program: Abyssal Mixing

提供9819531 MoumFunding是为了在夏威夷海脊附近进行一项大型协调实验(主页：夏威夷海洋混合实验)，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源途径，并实现该区域的大致能源收支。HOME项目的近场实验重点是研究夏威夷海脊附近的动力过程，特别是对正压潮汐强迫的响应，包括低模和高模内波的产生、传播和湍流耗散和混合。这一分项目将侧重于将横跨海脊的局部湍流和剪切与潮汐诱导的剪切和应变的时间变异性联系起来，这些变化是由研究平台翻转和海流计系泊的定点观测确定的。在大潮和小潮期间，将部署一艘深拖体(马林鱼)和一艘垂直微结构剖面仪(变色龙)。还将在海脊以南3000米处进行一些观测，以确定其他家庭调查人员观测到的高耗散率的空间变异性。

9819531 MoumFunding is provided to conduct a large coordinated experiment (HOME: Hawaiian Ocean Mixing 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 Near-field experiment of the HOME project focuses on the investigation of the dynamical processes in the immediate vicinity of the Hawaiian Ridge, and especially the response to barotropic tidal forcing including generation of low- and high-mode internal waves, propagation and turbulent dissipation and mixing. This sub-project will focus on relating the local turbulence and shear across the ridgetop to the temporal variability of the tidally-induced shear and strain determined by the fixed point observations from the research platform FLIP and current meter moorings. A deep towed body (Marlin) and a vertical microstructure profiler (Chameleon) will be deployed during spring and neap tides. Some observations will also be conducted south of the Ridge to depth of 3000 m in order to establish the spatial variability of high dissipation rates observed by other HOME investigators.
