PHYSICAL-FEATURES AND CHEMICAL-FEATURES IN THE COASTAL AREAS OF KAVALA AND ALEXANDROUPOLIS, NORTH AEGEAN SEA

Monthly measurements of temperature, salinity, chlorophyll - alpha and nutrients were conducted during the period September 1991 - December 1992 in the coastal areas of Kavala and Alexandroupolis. Lower concent rations of both nutrients and chlorophyll a were measured in Kavala co mpared to those in Alexandroupolis. In both studied areas mean annual values of N:P atomic ratio were relatively high (22.4 and 26.2 in Kava la and Alexandroupolis, respectively) although 45.2% and 44.1% of the measured values were lower than 15. This probably indicates a combined effect of the coastal environment, influenced by man, and the pelagic one which is known to be P limited (east Mediterranean Sea).
