The 1987 Reciprocal Tomography Experiment (RTE87): Internal-tide Mode-1 Amplitude Data from the Triangular Tomographic Array

Ocean acoustic tomography was used to measure mode-1, baroclinic tides radiating from the Hawaiian Ridge in 1987 during the Reciprocal Tomography Experiment (RTE87). Using reciprocal transmissions, the tomographic arrays measured the temperature signatures of the coherent radiation of mode-1 internal tides from the Ridge, together with barotropic tidal currents. This publication makes available the tomographic estimates for time series of mode-1 internal-wave amplitudes derived from the three paths of the RTE87 tomography array. The array was also used to accurately measure barotropic currents, dominated by tidal variations; these data are available separately.1987年开展的互易层析成像实验（Reciprocal Tomography Experiment，简称RTE87）中，研究人员借助海洋声学层析成像（Ocean acoustic tomography）技术，对源自夏威夷海脊的一阶斜压潮（mode-1 baroclinic tides）辐射过程进行了观测。通过互易传输（reciprocal transmissions）方式，该层析成像阵列（tomographic arrays）不仅捕获了该海脊发射的一阶内潮（mode-1 internal tides）相干辐射的温度特征，同时还测得正压潮流（barotropic tidal currents）相关数据。本数据集公开了基于RTE87层析成像阵列三条观测路径得到的一阶内波振幅时间序列的层析反演估计结果。该阵列同时还被用于精准测量以潮汐变化为主的正压流数据，此类数据可单独获取。
