Conductivity-Temperature-Depth (CTD) profiles from Norwegian Polar Institute cruise AO-I-2023 to the Fram Strait. The dataset includes profiles of sensor temperature, conductivity, dissolved oxygen, chlorophyll fluorescence, coloured dissolved organic matter fluorescence, beam attenuation, and calculated practical salinity (EOS-80). Profile data are from down casts only and made available in a vertical resolution of 1 decibar (i.e. averaged into 1-decibar bins). The dataset also includes laboratory measurements of salinity and chlorophyll a from Niskin bottle samples. Laboratory results for several core parameters are to be added successively. The data are contained in a single, self-documenting netCDF file. Profile data are organised in arrays with one column per cast and one row per depth bin (pressure bin). Bottle data are organised in arrays with one column per cast and one row per Niskin bottle. One-dimensional metadata (such as time and position) are organised as a single row with one column per cast. Two-dimensional metadata (such as sample number) relate to Niskin bottle data and are organised in arrays with one column per cast and one row per Niskin bottle. All variables have the same number of columns, equal to the total number of CTD casts. For full information on the sampling and processing routines, please refer to the AO-I-2023 cruise report (https://hdl.handle.net/11250/3089166) and the CTD post-cruise processing report (included as file here).
