Water temperatures followed the expected annual dynamics with winter 2012 minima (16.68 0.248C) and summer maxima (29.19 0.168C). No spatial variation in water temperature could be detected. Salinity exhibited seasonal fluctuations and reached maximum values (38.22
0.26 PSU 38.30 0.59 PSU) in winter and autumn 2012, respectively, whereas the lowest values (27.73 3.64 PSU) were measured in spring. Lowest values were observed at stations 1 and 2 due to the freshwater discharged. Minimum pH value (8.11) was recorded in winter 2012, 2013, while the highest value (8.40) was measured in autumn. The harbour's water was always well-oxygenated and reached maximum values in spring
