Sažetak
Oceanographic data collected in the framework of the ITHACA project have been examined in order to detect and interpret different physical processes in the area. One of the main objectives was to gain more information on internal tides at the Adriatic shelf break. The work comprised thermistor measurements carried out on the islands of Bisevo, Susac and Lastovo at 10 equidistant depths, between 4 and 40 m, on submarine cliffs opened to the southeast. These measurements were complemented and verified by using thermistor chain data collected in the framework of the DART project (DART06 cruises). Preliminary analysis revealed significant diurnal temperature oscillations at Lastovo. The strongest variations were driven by the sea/land breezes (middle of July 2006). However, at the end of June 2006 the diurnal wind forcing was not significant, whereas barotropic currents at a nearby ADCP station as well as sea levels at Split and Dubrovnik contained pronounced diurnal signal. The wind and tidal influence on temperature variability were separated by applying multiple cross wavelet spectral analysis with hourly wind and sea level (or barotropic current) data treated as inputs and isotherm heights at Lastovo considered as an output. The analysis confirmed that significant correlation between the tides and the thermocline oscillations existed at the end of June 2006.
