【 摘 要 】

Marine plastic pollution is one of the most serious problems in the marine environment. In this study we determined the abundance of plastic marine debris (large microplastic [1-5 mm] mesoplastic [5-25 mm] and macroplastic [>25 mm] on 2 beaches in Ambon Bay. The sampling was conducted during March 2018 using quadrats of 2 sizes. Macroplastics were sampled using large quadrats measuring 5 × 5m. Small quadrats measuring 0.5 x 0.5 m were used to collect large microplastics and mesoplastics. The respective abundances of large micro-(1-5 mm), meso-(5-25 mm) and macroplastic (>25 mm) were 68.8, 5, and 0.722 items.m-2. The highest abundance of marine plastic debris was found in the inner Ambon Bay. The results indicated a strong contribution of water mass circulation within Ambon Bay to the distribution of plastic debris abundance throughout the Bay.
