Hawaii Ocean Mixing Experiment: Nearfield Program: Observations of Internal Wave Propagation and Overturning

9819529粉红正在夏威夷海脊附近进行一项大型的协调实验(家：夏威夷海洋混合实验)，以确定地形崎岖的地点是否对全球海洋的混合负责。这些实验的目标是确定海洋混合的主要能量途径，并实现该地区的大致能量平衡。经过历史分析、模拟和调查工作，HOME项目的近场实验侧重于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。这一子项目将侧重于了解内潮和600米以上的内波场的特征。研究平台翻转将在大潮期间停泊在海脊南缘约20公里处的卡耶纳铂。将使用一个快速剖面式CTD和一个低位仰视的高分辨率声纳来实时显示水柱的分层、速度剪切和稳定性，使实验的移动部件能够实时修改采样策略。

9819529 PinkelA large coordinated experiment (HOME: Hawaiian Ocean Mixing Experiment) is underway near the Hawaiian Ridge to determine whether sites with rough topography are responsible for the mixing of the global ocean. The goals of the experiments are to identify the major energy pathways for ocean mixing and achieve an approximate energy budget for the region. Following historical analysis, modeling and survey work, 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 understanding the characteristics of the internal tide and the internal wave field in the upper 600 m. The research platform FLIP will be moored for about 40 days during Spring tides on the South edge of the ridge, approximately 20 km west of Kaena Pt. A rapidly profiling CTD and a lowered up-looking, high resolution sonar will be used to provide real-time display of the stratification, velocity shear and stability of the water column, enabling real-time modification of sampling strategies by the mobile components of the experiment.
