HOME: Farfield Program: Tomographic Tidal Energy Budget

提供资金在夏威夷海脊附近进行一项大型协调实验，以确定地形粗糙的地点是否是全球海洋混合的原因。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。同伴建模工作将主要集中在潮汐散射作为海洋混合的能源问题上，而在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，以确定强混合活动发生的地区的位置和普遍性。根据远场实验的这一特定组成部分，将在夏威夷海脊两侧部署层析阵列，以量化海脊处的正压能量通量会聚和与低模态斜压波辐射相关的通量发散。这一差异是衡量海岭可用于混合的潮汐动力的一个尺度。

Worcester/DushawFunding 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, a tomographic array will be deployed on either side of the Hawaiian ridge 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.
