Hydrography and carbon from Station M (OWSM) 2020-2021

The dataset contains hydrography and pCO2 data from a single array mooring covering the depths between 500 m and 2000 m (bottom) at Station M (OWSM) in the Norwegian Sea, in the framework of the NorEMSO project. The mooring was deployed in August 2020 and retrieved in August 2021. Measurements frequency is 1/1 hr for the hydrography and 1/12 hr for the pCO2 measurements. At 800 m and 1200 m nominal depth, the pressure has been calculated based on distance between the SBE sensors. QC flags from EuroSITES (OceanSITES) are used for all data, where flag 0 is used for raw data (unknown, no QC was performed) and flag 2-4 are used for data that have been QD-ed. The CO2 sensor data (at 500 m nominal depth) are validated by comparing the values towards calculated pCO2 from discrete Dissolved Inorganic Carbon (DIC) and Total Alkalinity (TA).
