Dataset of vertical temperature, turbidity and dissolved oxygen profiles obtained from the Revvatnet, lake close to Hornsund fjord. The measurements are made with SAIV A/S 208 STD/CTD (until 2023) and two separate RBR concerto CTDs (since 2024).
The data are stored in folders organized by the year (YYYY) of measurements. Each vertical profile is stored as an individual, tab-separated ASCII file. The filenames are formed from the date and time of measurement followed by the instrument, potential additional sensors and station names: YYYYMMDDhhmmss_instrument-sensors_station.txt. Each file includes eight headerlines with information on station name, geographical location (UTM), date and time of measurement (YYYY/MM/DD hh:mm), instrument and its serial number, source of financial support and data column names. The data columns include pressure (dbar), temperature (°C), turbidity (FTU/NTU), dissolved oxygen saturation (%) and dissolve oxygen concentration (mg/l). Measurements by RBR concerto CTDs have additional columns for Chlorophyll a fluorescence (μg/l) and Photosynthetically Active Radiation (PAR, μmol/m^2/s).
Note that this is a raw dataset without quality control.
