According to the findings of the study, chlorophyll-a variation is between 0.1 and 2.8 p.g/l. The
highest chlorophyll-a value was found at a depth of 20 m in spring when mucilage formation
was observed. Surface water temperatures at these stations varied between 11.4 and 22.4 °C.
The highest surface water temperature was 22.2 °C in September and the lowest surface water
temperature was 11.4 °C in December

C.1.3.1.1. Pollution from Ships

90% of world trade is carried out by sea, that is, by ships. From this point of view, the mana-
gement of wastes arising from the operational activities of ships in a way that does not cause
marine pollution is of great importance.

At the international level, By-laws within this scope are carried out within the framework of the
“International Convention for the Prevention of Pollution from Ships (MARPOL 73/78)”. Türkiye
became a party to the convention in 1990.

Necessary legislation has been published in line with our obligations arising from this conventi-
on and our national needs. At the beginning of this legislation is the “By-law on Waste Collection
from Ships and Control of Wastes” which was first published in 2004. In this context, as of 2023,
334 coastal facilities in Türkiye provide waste reception services through waste reception facili-
ties and 58 waste reception vessels.

C.1.3.1.2. Marine Litter Management

Marine litter is defined as permanent, processed solid materials discharged, discarded or left on
the shore or in the marine environment. Marine litter is a global problem that threatens the he-
alth of the oceans, seas and rivers and the organisms living in and interacting with these ecosys-
tems. Due to these effects, it is among the priority issues in national and international arena.
For this reason, Provincial Action Plans were prepared in all coastal provinces to combat marine
litter and started to be implemented in 2020.

Marine Litter Provincial Action Plans have been prepared for 5 years for all 28 coastal provinces
under the chairmanship of Governors with the participation and contributions of responsible
