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.

提供了9819531莫姆筹集，以进行夏威夷山脊附近的大型协调实验（家：夏威夷海洋混合实验），以确定是否造成了粗糙地形的地点，是否负责全球海洋的混合。目标是确定海洋混合的主要能量途径，并实现该地区的近似能量预算。家居项目的近场实验重点是研究夏威夷山脊附近的动力学过程，尤其是对正压潮汐强迫的反应，包括生成低模式内部和高模式的内部波，传播和湍流耗散和混合。该子项目将集中于将局部湍流和剪切横跨Ridgetop关联到潮汐诱导的剪切和应变的时间变异性，并由研究平台的固定点观测结果确定，从研究平台翻转和电流仪表系泊。在春季和nea潮中将部署一个深拖尸（Marlin）和垂直微观结构探测器（变色龙）。一些观察结果还将在山脊以南进行3000 m的深度，以确定其他家庭调查人员观察到的高消散率的空间变异性。
