The 2001 Hawaiian Ocean Mixing Experiment (HOME): High-frequency (>1cpd) Barotropic Current Data from the Southern Tomographic Array

Ocean acoustic tomography was used to measure tides in the farfield of the Hawaiian Ridge in 2001 during the Hawaiian Ocean Mixing Experiment (HOME). The measurements were components of a suite of large- and small-scale measurements obtained during HOME with the aim of illuminating the pathways of tidal energy that may be driving deep-ocean mixing. Using reciprocal transmissions, the tomographic arrays were designed to measure the radiation of mode-1 internal tides from the Ridge, together with barotropic tidal currents. This publication makes available the tomographic estimates for barotropic currents derived fromthe six paths of the southern HOME tomography array.2001年，在夏威夷海洋混合实验（Hawaiian Ocean Mixing Experiment，HOME）期间，研究人员采用海洋声学层析成像（Ocean acoustic tomography）技术，对夏威夷海脊远场区域的潮汐进行了观测。该观测数据是HOME实验中一系列大、小尺度观测项目的组成部分，其核心目标为阐明可能驱动深海混合的潮汐能量传播路径。实验采用互易传输方式搭建声学层析阵列，旨在同步测量该海脊产生的一阶模态内潮辐射信号与正压潮流。本数据集公开了基于HOME实验南部层析阵列六条传播路径得到的正压潮流声学层析反演估算结果。
