Benthic debris accumulation in bathyal grounds in the Antalya Bay, Eastern Mediterranean

Sunulan bu çalışma Ocak-Mayıs 2012 tarihleri arasında Antalya Körfezinde (doğu Akdeniz) yürütülmüştür. Geleneksel bir dip trolüne sahip olan araştırma gemisi kullanılarak 200 ile 800 m arasındaki derinliklerde örneklemeler yapıldı. Batial zonun bentiğinde bulunan büyük boyutlu deniz kirleticilerin materyal, bolluk ve dağılımları incelendi. 32 trol çekimi süresince toplamı 220 kg olan 920 parça kirletici toplandı. Çöpün yoğunluk miktarları tüm alan içerisinde 18,5-2.186,0 kg/km2 ve 115- 2.762,0 parça/km2 arasında değişmektedir. Derinlik katmanları ile çöplerin herhangi bir gurubunun dağılımı arasında anlamlı bir fark bulunmamıştır (P

Antalya Körfezi (Doğu Akdeniz) batial zonunda bentik çöp birikimi

The present study was carried out in the Bay of Antalya (eastern Mediterranean) between January and May 2012. A conventional bottom trawl was operated onboard of an research vessel. The depth of the sampling area varied between 200 and 800 m. The material, abundance and distribution of large marine pollutants were investigated in bathyal benthic zone. During the 32 hauls, a total of 220 kg debris and 920 items were collected. The mass of overall debris concentration range from 18.5 to 2,186 kg/km2, number of debris range from 115 to 2,762 item/km2. There is no significant difference between depth ranges for any kind of marine debris (P<0.05). The number percentage of plastic metal, glass, and other debris in total were 81.1%, 2.2%, 3.9% and 12.8%, respectively. Plastic litter was the most dominant material category by means of number.
