CTD

During the eleven cruises in the Aegean, Ionian and Levantine Seas, CTD data were collected on board R/V Aegaio from an extensive grid of stations with almost nominal spacing of 0.5 degree in latitude and longitude. Occasionally, mesoscale resolution grids were occupied. The CTD was equipped with new and/or calibrated pressure, temperature, conductivity and oxygen sensors. The measurements were taken at a rate of 33 scans/sec averaged in situ by software over one second intervals, thus obtaining values at about 0.7 dbar intervals, followed by 3 point interpolation to nominal depths (every dbar). Post cruise calibration in CTD salinity was undertaken using water sample salinity measured by an AUTOSAL salinometer. Intercalibration of temperature and salinity carried out in some of the sub-sets, within the context of POEM programme. The number of stations that were visited during the projects is approximately 1450. The research programmes in the frame of which the data sets were gathered aimed towards the best understanding of the phenomenology and the dynamics of the seas of the Eastern Mediterranean.
