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 (17.04 3.23 mg l

) and minimum values in
summer (9.44 3.16 mg l
