AB  - This study presents the first data on the benthic marine litter in the Marmara Sea, Turkey. To obtain the data, bottom trawl surveys were conducted at 34 sites between May 2017 and February 2018. The litter items were sampled and sorted following the MEDITS’ relevant instructions. 660 pieces of litter, weighing 434.9 kg, were sampled. The litter density was found to range between 27.5 n/km2 and 661.2 n/km2, averaging 73.9 n/km2, and the obtained items’ weightss ranged between 0.03 kg/km2 and 1597.8 kg/km2, averaging 48.7 kg/km2. The plastic group L1 constituted 71.7% of the trawled litter. The highest mean litter density was detected in the Northeastern Marmara Sea in spring and summer in 2018. The mean benthic litter density was found to be higher than the nearby areas. It was concluded that more effort should be invested in reducing marine pollution.

N2  - Bu çalışma, Marmara Denizi'ndeki bentik deniz çöpüne ilişkin ilk verileri ortaya koymaktadır. Bu amaçla Mayıs 2017-Şubat 2018 tarihleri arasında 34 istasyonda dip trolü araştırması yapılmıştır. Çöplerin kategorize edilmesi ve sınıflandırılması MEDIT standardına göre belirlenmiştir. Toplam 660 adet ve 434,9 kg çöp tespit edilmiştir. Çöp yoğunluğu 27,5 adet/km2 - 661,2 adet/km2 arasında değişirken, ortalama 73,9 adet/km2 tespit edilmiştir, ağırlık değerleri 0,03 kg/km2 - 1597,8 kg/km2 arasında değişmiş ve ortalama 48,7 kg/km2 belirlenmiştir. Plastik (L1) grubu toplam çöp bolluğunun %71,7'sini oluşturmuştur. 2018 yılında, ilkbahar ve yaz mevsimlerinde ve Marmara Denizi'nin kuzeydoğu kesiminde daha yüksek çöp yoğunluğu tespit edilmiştir. Deniz kirliliğini azaltmak için daha etkin mücadele gerektiği görülmüştür.
