Egbert 9819518Funding 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. This modeling effort will focus primarily on computing barotropic inverse solutions around the Hawaiian Ridge using existing tidal models, the altimetric data from TOPEX/POSEIDON and the tomographic data collected during the Farfield experiment. Detailed barotropic flux calculation with error bars will calculated. Finall, the barotropic inversion code will be modified to accommodate stratification in order to calculate the energy flux of low-order baroclinic modes.

拨款用于在夏威夷海脊附近进行一项大型协调实验，以确定地形粗糙的地点是否对全球海洋的混合负责。目标是确定海洋混合的主要能量途径，并实现该区域的大致能量收支。这项建模工作将主要集中在利用现有的潮汐模型、TOPEX/POSEIDON的测高数据和Farfield实验期间收集的层析成像数据，计算夏威夷山脊周围的正压反解。将计算带有误差条的详细正压通量计算。最后，为了计算低阶斜压模态的能量通量，将正压反演代码进行修改以适应分层。
