Güllük Lagoon (Aegean Sea, Turkey) Ecosystems
Güllük Lagoon has an area of 2500 decares with a depth of 0.5-5.0 m and is connected to Güllük Bay by a channel. In this study, samplings of phytoplankton and benthos were taken physico-chemical parameters were recorded monthly during 1993 at 5 stations. The temperature reached a minimum of 10.42°C...
