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

PinkelA在夏威夷海岭附近正在进行一项大型协调实验（HOME: Hawaiian Ocean Mixing experiment），以确定地形粗糙的地点是否对全球海洋的混合负责。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收支。HOME项目的近场实验在进行历史分析、模拟和实测工作的基础上，重点研究了夏威夷海岭附近的动力过程，特别是对正压潮汐强迫的响应，包括低模态和高模态内波的产生、传播和湍流耗散和混合。该子项目将重点了解600米以上的内潮和内波场特征。研究平台FLIP将在春潮期间停泊在海脊南缘约40天，位于Kaena Pt以西约20公里处。快速剖面CTD和低仰视高分辨率声纳将用于提供分层、速度剪切和水柱稳定性的实时显示，从而使实验的移动组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.
