Abstract : A sequence of three cruises was made during the period Aug-Nov 1984. The primary purpose was to investigate the late summer water-mass variability and the interior flow structure of the Sardinia-Sicily opening. During the observational period four moorings were deployed, each instrumented with current meters and a listening station to permit acoustic tracking of five subsurface floats. Data recovery was very good and the instruments themselves were all recovered in good condition. The period during which the instruments were operational was approximately 70 days. During the cruises hydro-casts were made using CTD, XBT, and water bottles in a station grid that covered the entire Southern Tyrrhenian and the Sardinia Channel. Water samples were taken for the control of salinity and for the analysis of oxygen, silicate and phosphate. Some benthic heat flux observations were conducted in the vicinity of the Eolian Islands. Keywords: Electrical conductivity; Sea water temperature; Ocean; Current measurement; Geothermal heating; Interior flow; Levantine intermediate water; Remote sensing; Subsurface floats; Summer; Thermohaline circulation; Expendable bathythermograph data.
