Water temperature measurements from RBR Solo thermistor strings moored in the South Atlantic Ocean basin (16 S), both on and off of the Mid-Atlantic Ridge on cruise JC275, February - March 2025.

This dataset contains water temperature values measured by RBR Solo thermistor sensors deployed on two moorings. One mooring was deployed within the South Atlantic Ocean basin at 16 S and 19 W from the 25th of February 2025 to the 18th of March 2025. The other was deployed within the Mid-Atlantic Ridge at 16 S and 13 W from the 28th of February 2025 to the 19th of March 2025. The sensors measured at 1 sample per minute and the temperature data were calibrated using calibrated CTD data from casts near the mooring sites. The data have also been trimmed to remove pre- and post- deployment data (26th of February to 17th of March 2025, and 1st of March to 19th of March 2025, respectively). These data were collected to contrast water features both on and off of the ridge, as part of the NERC Discovery Science grant NE/X013758/1 titled "Enhanced carbon export driven by internal tides over the mid-Atlantic ridge (CarTRidge)".
