The wave characteristics on the Constanta near-shore area are estimated from long-term measurements (1966 - 2010). For the 1966 - 1995 period the data had been obtained by detecting the vertical movement of a surface buoy at 1km from shore (44°10'19"N, 28°39'52"E at 12 m depth). After 1996, visual observations at the same location are available. Similar data from systematic visual observations at an offshore drilling platform situated on the inner continental shelf at 70 km from the coast (44°31'N, 29°34'E) cover the 2003-2009 period. Systematic wave records (at 1.5 hours interval) carried out at Mamaia Bay during 2006 - 2010 have been analyzed in order to estimate the statistical characteristics of the significant wave height and period, especially during storms. Changes in the long-term evolution of the wave regime are mainly due to meteorological factors that have considerable time variability. The overall average of calm sea state occurrence is about 55%; the average wave height is about one meter, with maximum measured wave height in 45 years being 6.0m. The mean wave period is approximately 4.5s, and the overall average height for the entire period is only about half a meter, indicating a moderate sea state regime. [ABSTRACT FROM AUTHOR] |
