SEA-LEVEL VARIATIONS IN THE EASTERN COASTS OF THE AEGEAN-SEA

Characteristics of sea-level variations in the eastern coasts of the A egean Sea have been investigated using time series of hourly sea-level data from Bozcaada, Izmir and Bodrum. Short, tidal and long periods o f oscillations have been identified. Short-period oscillations with pe riodicity of 3.5-4.2 h are attributed to seiche-like motions at Izmir Bay. The tidal oscillations are dominated by semi-diurnal constituents with supplementary contributions from the diurnal constituents. The s ubtidal water-level data from Izmir have been analysed in terms of loc al barometric pressure and observed wind. The seasonal cycle was compu ted for the monthly averages of mean sea-level data. (C) 1996 Academic Press Limited
