Dataset consisting of continuous measurements of temperature and salinity from bottom-moored instruments. The measurements are obtained at fixed depths in varying locations across the Hornsund fjord. All data is averaged to one-hour intervals. The files are named with the mooring ID consisting of the measured parameters (CTD for Conductivity-Temperature-Depth, TD for Temperature-Depth, T for Temperature) and a running number followed by the deployment and recovery dates (format YYYYMMDD) as well as the stage of data processing (for this dataset "hourly"). However, when observations are made at one of the stations included in the CTD monitoring program, the station name is used instead of a mooring ID.
The header in each file consists of 10 lines and includes information on geographical location (decimal degrees), deployment and recovery dates (YYYY-MM-DDThh:mm:ss), bottom and instrument depths, the equipment used for measurements and source of financial support. There are 4-7 data columns. For the T and TD moorings, the columns are Date/Time (YYYY-MM-DDThh:mm:ss), Pressure (dbar), Depth (m) and Temperature (°C). For the moorings without pressure sensor (only T), pressure and depth columns are marked as NaN and the average instrument depth can be found in the header. The CTD moorings include additional columns for Potential temperature (°C), Practical salinity and Density represented as Sigma-Theta (kg/m**3). Conductivity is not included in this dataset, but can be found in the raw data. Suspicious data and outliers are detected and removed and the data is smoothed. No interpolation is performed and missing data are marked with NaN. The data columns are tab-delimited and the data stored in ASCII-formatted .txt-files.
