Short summary
This study presents 30 years of water temperature data from expendable bathythermograph (XBT) probes collected between Aotearoa / New Zealand and the Ross Sea (Antarctica). Gathered during research cruises by the Italian National Antarctic Research Program, the data were rigorously verified and corrected for depth and temperature bias. This dataset provides a valuable insight into the Southern Ocean's climate and enhances satellite observations and ocean models.
