9819535 GreggFunding 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 mapping the spatial extent and spring/neap variability of the internal tide over Kaena Pt. Ridge. Specifically, the Advanced microstructure profiler (AMP) will be deployed with a depth-cycling towed body from the stern of the R/V Revelle while moving slowly across and parallel to the Ridge. The shipboard sonar will simultaneously map the velocity field to 700 m. Upward and downward looking Acoustic Doppler Current Profilers (ADCP) on the towed body will measure deep shear closer to the bottom and with higher vertical resolution that can be measured by shipboard ADCPs.

9819535 GreggFunding被提供用于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混合负有责任。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绘制Kaena铂上内部潮汐的空间范围和春潮/小潮变化图。里奇。具体地说，先进微结构剖面仪(AMP)将部署一个从R/V Revelle船尾开始的深度循环拖曳车身，同时缓慢穿过并平行于山脊移动。舰载声纳将同时测绘700米的速度场。拖体上的向上和向下俯视声学多普勒海流剖面仪(ADCP)将测量更接近底部的深度切变，并具有更高的垂直分辨率，可以通过舰载ADCP测量。
