Seasonal variability of dynamical and thermohaline properties in the Otranto Strait area - 1989/1990

From November 1989 to August 1990 four seasonal oceanographic cruises were performed in the Otranto Strait area by R.V. "Andrija Mohorovcic". It is supposed that November, March, May and August are representatives for autumn, winter, spring and summer seasons, respectively. Two current meter arrays were moored in the Strait: the first one near the West coast (P-1) and the second one near the East coast (P-2). Short period current measurements at two stations in the Otranto Strait indicate two layered circulation, sometimes with only one layer, especially at station P-2. The most intensive folw is usually between 500 m and 800 m. Maximum current speeds were registred at station P-1 at the depth of 500 m in March 1990 (64 cm/s), while at station P-1 at the depth of 5 m in May 1990 (49 cm/s). Measurements in March and May 1990 supported well known structure of exchange of water masses in the Otranto Strait, with inflowing (northward) currrents along the Albanian coast, and outflowing (southward) currents along the Italian coast. Such current regime can be called "typical situation". Meanwhile in August 1990, an opposite nontypical exchange of water masses was registered, with outflowing current along the Albanian coast and inflowing current along the Italian coast.
