This dataset contains measurements from the T/V Kagoshima Maru KG1515 cruise in the Tokara Strait. The following data are for the publication of a manuscript entitled "Internal solitary waves in the Kuroshio observed in the Tokara Strait" by Senjyu, T. et al., which will be submitted to Scientific Reports. All the files are written in text format. ADCP data: KG1515_ADCP_ptuv.dat ----- Moored ADCP data for pressure, temperature, zonal (u) & meridional (v) velocities KG1515_ADCP_w.dat ----- Moored ADCP data for vertical velocity (w) KG1515_ADCP_Echo.dat ----- Moored ADCP data for echo intensity (averaged values for all transducers) KG1515_ADCP_Echo1.dat ----- Moored ADCP data for echo intensity from the transducer No. 1 KG1515_ADCP_Echo2.dat ----- Moored ADCP data for echo intensity from the transducer No. 2 KG1515_ADCP_Echo3.dat ----- Moored ADCP data for echo intensity from the transducer No. 3 KG1515_ADCP_Echo4.dat ----- Moored ADCP data for echo intensity from the transducer No. 4 * The ADCP measurement depths are converted from the observation layer number as follow: Depth (m) = 574 - (layer No. - 1) * 8 Hydrographic data: KG1515_CTD_M01.dat ----- CTD data at the mooring site
