Hawaii Ocean Mixing Experiment: Farfield Program: WHOI Contribution to Observing the Barotropic Ocean Tides

Care/FillouxFunding被提供用于在夏威夷海脊附近进行一项大型协调实验，以确定地形崎岖的地点是否对全球海洋的混合负有责任。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。与之配套的模拟工作将主要集中在作为海洋混合能源的潮汐散射问题上，而对夏威夷群岛附近收集的数据的历史分析将有助于指导调查计划，以确定发生强烈混合活动的区域的位置和普遍存在。根据法菲尔德实验的这一特殊组成部分，将在夏威夷海脊的两侧部署一组水平静电计和海底压力记录器，以补充层析成像阵列。其目的是量化正压能流在脊线的辐合和与低模斜压波辐射相关的通量散度。这一差异是对海脊可用于混合的潮汐功率的衡量。

Chave/ FillouxFunding is provided to conduct a large coordinated 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. A companion modeling effort will focus primarily on the issue of tidal scattering as an energy source for ocean mixing while a historical analysis of data collected in the vicinity of the Hawaiian Islands will help guide the survey program in determining the location and ubiquity of regions where strong mixing activity takes place. Under this particular component of the Farfield experiment, an array of horizontal electrometer and bottom pressure recorders will be deployed on either side of the Hawaiian Ridge to complement a tomographic array. The objective is to quantify the barotropic energy flux convergence at the Ridge and the flux divergence associated with low mode baroclinic waves radiation. The difference is a measure of the tidal power available for mixing at the Ridge.
