Sea surface temperature anomalies along the Black Sea Region coast of Turkey (1971-2010 period)

The aim of this study is finding an answer to a question how the development and change of sea surface temperature (SST) anomalies were at the Black Sea Region in Turkey between 1971 and 2010. For that purpose, SST data of Amasra, Inebolu, Sinop, Samsun, Ordu, Giresun and Hopa stations were used. Air temperature is meteorological element having a clearest effect on annual and seasonal SST anomalies. Also in winter North Atlantic Oscillation (NAO) and North Sea Hazar Pattern (NCP) and in spring North Sea Hazar Pattern (NCP) are noticeably influential. In the study area, SST anomalies showed important annual and seasonal variations. It is designated that annual average SST anomaly showed asymmetric diffusion from its values average variation aspect in all stations, form standard variation aspect it showed symmetrical in Hopa and in the others it showed asymmetric diffusion. In 1971-2010 generally SST anomalies showed decrease in Ordu and Hopa, however, it showed an increasing tendency in the other stations. The values of anomaly showed decrease in Black Sea coasts between Sinop and Hopa in spring and summer, they showed an increasing tendency in the whole Black Sea coast zone in winter and autumn. SST and the anomaly values generally showed decrease in Black Sea coasts in 1971-2000, they showed increase between 2001 and 2010. The lowest anomaly values were designated in the period 1981-2000 and the highest anomaly values were generally designated in the period 2001-2010.
