Physical and biogeochemical data collected by CTD in Masfjorden and Lurefjorden, Vestland, Norway during cruise KB2023006004 in February 2023.

The files contain temperature, practical salinity, oxygen, and depth measurements binned into 1 db pressure bins, collected using a Seabird SBE 11plus V 5.2 CTD and post-processed with the Seasoft software package during cruise KB2023006004 in February 2023. Data were collected in Masfjorden, Lurefjorden, and nearby fjords in Vestland, Norway. Uncalibrated fluorescence, PAR, SPAR, and transmission data from the CTD are included, as are water sample data (Oxygen, Dissolved Inorganic Carbon, Alkalinity and nutrients) collected during the cruise. There were issues with the Winkler titration; the Winkler data were flagged as potentially bad, and no oxygen calibration was carried out. The cruise was organized as a part of the course GEOF337 and GEOF232 run by the Geophysical Institute, University of Bergen. Data can be downloaded as one .nc file or three .txt file, where data in the .txt-files are separated into downcast (KB2023006004_CTD.txt) and bottle (KB2023006004_btl.txt) data and where meta-data are provided in KB2023006004_meat-data.txt.
