Analysis of the Water Level Variations in the Eastern Black Sea

Huseyin Yuce


A sequence of two-hourly water level observations at Samsun and Trabzon located on the eastern Black Sea coast have- been analyzed in order to investigate the general nature of the sea level variations. Long (several days) oscillations of non-tidal origin have been identified. Water level fluctuations are dominated by energy inputs from low frequency sea level variations. The tidal oscillations are very small in amplitude with a spring range of 0.74 and 1.9 cm in Samsun and Trabzon, respectively. Tidal oscillations are dominated by semi-diurnal constituents. Short periods of oscillation (7.1, 4.3, 3.0. 2.3 hr) have been identified in the sea level spectrum.
