Resonant excitation of diurnal internal tides in the Adriatic : SESE and Oceans Institute Seminar Other events...
Oceanographic data collected during 2006 have offered new information on diurnal internal tides in the Adriatic. The most pronounced diurnal temperature variations were detected at the island of Lastovo and they were driven by sea/land breezes. However, three tide-dominated episodes were extracted and the analysis showed the presence of different amplitude and phase relationships between the tidal forcing and the isotherm variability during these intervals, this being indicative of possible resonant excitation of internal tides at Lastovo. Theoretical analysis of the trapping of long-period internal waves around an island corresponding to Lastovo confirmed that stratification properties were close to resonant ones during the summer of 2006. The numerical study of the current flow around a cylindrical island in the stratified sea of constant depth provided more details on resonant forcing. The present investigation revealed that even in a shallow area of high bathymetric complexity subjected to micro-tides, large amplitude internal waves at diurnal tidal frequency could be generated by near-resonant interaction of tidal flow with the island.

Given that Go8 European Fellowship promotes relationships between Australia and fellows' home countries and between the Go8 universities and fellows' home universities, short info on institutions involved in marine research in Croatia will be given.
