30m carbon dioxide data from Porcupine Abyssal Plain Sustained Observatory (PAP-SO) collected over 3-months collected from 3rd April (deployed on DY130) to 13th June 2021 (recovered on JC231), at 8-hourly resolution using a ProOceanus CV sensor (NDIR detection).

As part of the Climate Linked Atlantic Sector Science (CLASS) project at the Porcupine Abyssal Plain Sustained Observatory (PAP-SO, location 49N, -16.5W) 3-months of subsurface (30m) Carbon dioxide data were collected at 8-hourly resolution using a ProOceanus CV sensor (NDIR detection) attached to the sensor frame of the PAP1 mooring. Data are available at 8-hour resolution from 3rd April (deployed on DY130) to 13th June 2021 (sensor was collected 5th May 2022 on JC231).
