Summary: This project is envisaged as a contribution to the understanding of the barotropic and baroclinic dynamics on the Adriatic shelf in general and in selected regions along the Croatian coast in particular. There are 2 major characteristics of the project: it is founded on relevant previous investigations of the Adriatic Sea, our own as well as of other researchers, and on balanced use of theory, empirical data (in situ and remotely sensed) and computer simulations. The research has been organizedin 2 major parts. The first has covered short-period motions, i.e. wind-induced currents, free and forced oscillations, andinertial oscillations. The second dealt with lower-frequency motions, i.e. spatial and temporal variability of thetemperature and salinity of the water column in the northern Adriatic, and current variability at the scale of about 10 days. Empirical part has been based on existing, partly analysed data, as well as on those collected within the project. Established connections with some international institutions have been used to provide remote sensing data. Computer simulations provided dynamic sintheses of theoretical and empirical findings.

Keywords: wind induced currents, mathematical modelling, remote sensing, satellite oceanography

Research goals: The goal of the proposed research is to study selected aspects of the barotropic and baroclinic dynamics of the Adriatic Sea and its marginal basins and areas. Selected segments have been organized into 2 thematic units. The first covers research in domain of shorter-period motions, triggered by mechanical influence of the atmosphere on the sea (air pressure and wind). Expected contribution is better understanding of the wind-induced dynamics on the Adriatic shelf and in the marginal areas (manifested through oscillations of sea level and variations in current field). The research should also contribute to improved knowledge of the mechanism of vertical eddy diffusion and the sea response to heterogeneous wind forcing (sirocco, bora). Also expected is better understanding of forced oscillations (due to slower atmospheric changes) and free oscillations (due to faster atmospheric changes) of the whole Adriatic and its smaller basins. The shallowness of the shelf and marginal basins also warrants the attention to the mechanisms of bottom friction and damping. The second thematic unit covers lower-frequency motions, directly affected by the exchange processes at the sea-atmosphere interface (as well as by redistribution of heat and salt in the sea) and indirectly by the wind. Specific contribution of this part is expected through improved knowledge and understanding of the spatial and temporal variability of residual motions, and some insight into the mesoscale dynamics of the northern Adriatic. Working towards these goals would enlarge our fundamental knowledge of the physical oceanography of the Adriatic Sea, and thereby enhance the possibility of its application.
