Download CTD/XCTD Data

     As the "TOCS (Tropical Ocean Climate Study)" project, vertical profiles of temperature and salinity in the western tropical Pacific ocean and in the eastern Indian Ocean were measured by using CTD (Conductivity, Temperature and Depth meter) and XCTD (eXpendable Conductivity, Temperature and Depth meter). The data listed in this web is just a part of our data from the western tropical Pacific Ocean and the eastern Indian Ocean, which were observed by R/V Kaiyo. The rest of our CTD/XCTD data, which were observed by R/V Mirai, is open through the Mirai data web (

     To download the CTD/XCTD data, click the "Cruise ID" in each row in the table below, then you can link to the FTP server. If you click the folder mark, then you can download all the CTD data in the cruise, and if you click the mark of individual file, then you can download each CTD/XCTD data. The data format is described in readme_CTD.txt and readme_XCTD.txt.
