Chapter Posidonia oceanica monitoring system on the coast of Aegean Sea of Turkey

Seagrass monitoring is a basic tool for measuring the condition of meadows in parallel to the environmental conditions. Posidonia oceanica meadows are very sensitive to anthropogenic effects. In the present study, two monitoring stations of Posidonia oceanica meadows were established on the Aegean coasts of Turkey in the years 2018 and 2019, at 26 m depth in Ildır Bay (İzmir, Turkey), and at 33 m depth in Kara Ada (İzmir, Turkey). The P. oceanica meadows upper and lower limits were defined by balisage systems. In the laboratory, lepidochronological, morphometric, and phenological parameters were also studied

Vertical distribution of mucilage typology in the water column after a massive mucilage formation in the surface waters of the Sea of Marmara

The vertical distribution of mucilage aggregates is described for the Sea of Marmara in July 2021. In order to understand the vertical distribution of mucilage aggregates, CTD measurements and underwater video records were obtained from 10 stations in the Sea of Marmara. Nine different types of mucilage aggregates were observed during this study. Flocs were observed in the entire surface waters of the Sea of Marmara. The biggest type of mucilage aggregates in terms of size was clouds. Vertical distribution of mucilage in the water column had a distinct distribution for different types and this distribution was same for all regions. Even though it was not possible to monitor the deep basin, this study confirms that mucilage aggregates passed the halocline and were recorded up to 60 m depth in the water column
