Dataset identification

Title of datasetCTD data from FRV Alba na Mara 0919A cruise
Narrative summary of dataset9 CTD casts collected by Marine Scotland Science on cruise FRV Alba na Mara 0919A in the Moray Firth (North Sea).
Summary of processing methodologyData Processing: The CTD data were processed by Marine Scotland using the Sea-Bird SeaSoft routines as recommended in the SeaSoft manual for model type Sea-Bird SBE19plus. Pressure data were binned to 1 dbar using SeaSoft and the primary temperature and conductivity channels were adjusted to produce 'edit' channels. Marine Scotland regards the 'edit' channels as the definitive version of the data. The adjustments consisted of a de-spiking process using Marine Scotland in-house visualisation software and, as necessary, application of a low pass filter as described in Sy (1985). Field Calibrations: For a number of the cruises Marine Scotland used water samples collected during the CTD casts to generate calibration equations for the conductivity and fluorescence channels. However, these calibrations were not applied to the data by the originator. Sy A., 1985. An alternative editing technique for oceanographic data. Deep Sea Research, 32 (12), 1591-1599.
