9819534 FlamentFunding is provided to conduct a large coordinated experiment, the Hawaiian Ocean Mixing Experiment (HOME), 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. An array of four High Frequency radars will be deployed on the west coast of Oahu and on the east coast of Kauai to study the current fields over the area of the HOME nearfield current meter array and the tidal propagation region south of the submerged Kaena ridge. The current measurements will be separated into a low-frequency mesoscale component, a mean flow, and spectrally separable tidal constituents. With the aid of high resolution bathymetry, an attempt will be made to separate the baroclinic and the barotropic components of the major constituents, and compare them with a decomposition based on their coherence with the astronomical forcing. Near-surface ADCP data from the nearfield moorings will be used to assess the quality of the radar data.

9819534 FlamentFunding提供资金进行一个大型的协调实验，夏威夷海洋混合实验（HOME），在夏威夷海脊附近，以确定是否有粗糙地形的网站负责全球海洋的混合。目标是确定海洋混合的主要能源途径，并为该区域实现大致的能源预算。将在奥陶纪西海岸和考艾岛东海岸部署一个由四个高频雷达组成的阵列，以研究HOME近场海流计阵列区域和淹没的Kaena山脊以南的潮汐传播区域的海流场。 目前的测量将分为低频中尺度分量，平均流量，和光谱可分离的潮汐成分。借助于高分辨率水深测量，将试图分离主要成分的斜压和正压分量，并将它们与基于它们与天文强迫的一致性的分解进行比较。近场系泊装置的近地表ADCP数据将用于评估雷达数据的质量。
