| In order to check the sea-level variability in the vicinity of Lampedusa Island (in the frame of Topex/Poseidon altimeter calibration), a numerical model of the tides for the Strait of Sicily and adjacent area has been performed. Cotidal and co-range charts for the main diurnal and semidiurnal constituents are drawn and the model results are compared with in situ data. Position of amphidromes for these constituents is also clarified: a strong semidiurnal resonance observed in the Gulf of Gabes is well reproduced in the model. Semidiurnal tidal currents are found to be important at the Adventure Bank (South-West of Sicily) and in the Gulf of Gabes. Diurnal tidal current, dominant on Adventure Bank, are due to energy trapped around the Western extremity of... |
