Abstract:
This is a conductivity, temperature, pressure, and dissolved oxygen dataset obtained by Umitaka-Maru cruise during the year of 2011-2019. For the purpose of analysing long term variability, only the data observed along 110E and 115E are selected. Also, only the data observed in the region south of 57S, where the spacial density of observation increases, are selected. All the data were observed in January. The methodologies for data processing, water sampling, measurements, and data calibration followed the recommendations for the instruments and methods of the Global Ocean Ship-Based Hydrographic Investigation Program (GO-SHIP) to the greatest extent possible.
