2020~2021년 동안의 울릉도 북서쪽 해안의 해양쓰레기 분포 특성

Abstract

Ulleungdo, located in the middle of the East Sea, has an excellent marine ecosystem as the first marine protected area on the East Coast. However, as marine litter of various origins is deposited by wind and currents, scientific management and monitoring of marine debris is required. From 2019, national beach litter monitoring was conducted on Ulleungdo, and this study was conducted as part of the national beach litter monitoring. During a total of 6 surveys, 35% of the total marine debris was collected in April, during spring, out of a total of 1,172 marine debris, and by type, plastics accounted for 62% and wood accounted for 36%. Foreign origins with confirmed nationality accounted for 8.6% of the total marine litter, and marine litter of Chinese origin accounted for 85%. In Ulleungdo coast, the proportion of hard-type garbage such as drinking water bottles among plastic marine garbage was high compared to the distribution characteristics of coastal garbage nationwide. This paper is meaningful as the first report on Ulleungdo coastal debris monitoring, and in order to understand the exact distribution characteristics of Ulleungdo coastal garbage in the future, it is necessary to expand the monitoring station through resident participation.
