Processed MPS-mounted CTD data from Maria S. Merian cruise MSM111 BAFFDEEP

Research expedition MSM111 took place from September 9th, 2022 (Reykjavik, Iceland) to October 10th, 2022 (St. John's, Canada). CTD data for 8 stations with a total of 15 individual casts were recorded using a Sea & Sun Technology CTD90M (SN 979) down to depths of 700m. The CTD was mounted on a Hydro-BIOS MPS midi and equipped with the following sensors: Temperature sensor Pt100 model 1509 (Thermal Developments International), Conductivity sensor 7-pole platinum coated electrode cell in quartz glass (Sea & Sun Technology), Seapoint Chlorophyll Fluorometer (Seapoint) and dissolved oxygen sensor (DO522M18, Clark type, OxyGuard). The data files contain the data for temperature, salinity, density, chlorophyll a concentration and photosynthetically active radiation; as raw data and processed and flagged according to the recommendations for real-time data processing of EuroGOOS and GTSPP, as well as the outlier detection method CoTeDe (https://github.com/castelao/CoTeDe). TEOS-10 unit conversions have been performed with the GSW Oceanographic Toolbox (McDougall and Barker, 2011).
