Dissolved oxygen concentration at 1m on the PAP1 mooring measured with an Aanderraa optode sensor from the Porcupine Abyssal Plain - Sustained Observatory (PAP-SO) (~49N, 16.5W) deployed on JC247 12 May 2023 to 31st August 2023.

Dissolved oxygen data (~1m depth on the Met Office (MO) Mobilis buoy keel) collected at the Porcupine Abyssal Plain - Sustained Observatory (PAP-SO) (49N, 16.5W) in the North East Atlantic ocean. Data were collected from 18:00 12th May 2023 (deployed on JC247) to 17:00 31 Aug 2023 as part of the CLASS project using an Aanderraa 4330 Optode (SN1279) with AML UV light used for the first time at PAP to reduce biofouling. Data has been processed assuming a constant salinity of 35.5. This concatenated file was generated by PAP_BuoyHub_proc21.c version 1.20. This dataset was collected and generated by scientists at the National Oceanography Centre, Southampton, UK.
