This data set contains the CTD data collected from the RV URANIA of the CNR (Italy) during the PRIMO-94 and PRIMO-94B cruises (20-29 May 1994 and 5-18 October 1994). These cruises were part of an intensive field program in the Sicily Channel and in the southern Tyrrhenian basin conducted by the Stazione Oceanografica of CNR in different periods from 1993 to 1995. Data have been used in several studies (see References). CTD profiles were collected using a Neil-Brown MKIII CTD. The probe was calibrated in temperature and conductivity at the SACLANT Center of La Spezia, before and after each cruise, and at sea in salinity and oxygen, against  water samples. Declared instrumental precisions were 0.002 °C for temperature and 0.005 for salinity (PSS-78).  The data set is provided per cruise as ODV Spreadsheet files in TXT format, containing: • Cruise name • Station number • Type of acquisition (here C) • Date in mon/day/yr and Time in hh:mm:ss • Coordinates in Longitude [degrees_east] and Latitude [degrees_north] • Bottom depth [m] • Depth, salt water [m] • Temperature, IPTS-68 [degC] • Conductivity [S/m] • Temperature, ITS-90 [degC] • Salinity, PSS-78 (Practical Salinity) • Dissolved oxygen [ml/l]
