Water current velocity and temperature measurements from Nortek Aquadopp doppler current meters moored in the South Atlantic Ocean basin, both on and off of the Mid-Atlantic Ridge on cruise JC275, February - March 2025

This dataset contains eastward, northward, and upward water current velocities measured by seventeen Nortek Aquadopp 6000 3D Doppler current meters 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 20th of March 2025. The moorings were deployed and recovered from the RRS James Cook during research cruise JC275. The data were averaged over 50 seconds every 4 minutes and have been quality controlled. 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)".
