Floating debris was recorded from a training ship, #1 Kwanaksan, of Pukyong National University with about 10 knots speed during August 19∼26, 1996. The area sampled is the East Coast of Korea, divided into 33 unit segments on survey routes. Debris fabrication materials were categorized using the following; man - made or natural wood items, paper, cardboard, nylon rope, netting, styrofoam and plastics, floating metal and glass containers. All identified items within a 100±2 m wide band were recorded but ignored if beyond this boundary. The results of distribution and composition of floating debris in the area are as follows: 1. The quantities of debris during the summer were distributed from 1.8∼52 items per ㎢. The most obvious trend is the widespread distribution of all debris. 2. The highest densities of all debris were discovered in the vicinity of Pusan and Ulsan area. Especially Styrofoam & plastics were observed in 81% of sampled area, next is wood items, 9.1%. Nylon netting & rope was the least widespread pollutant. 3. The relationship between distribution of debris and surface currents of the area was not apparently revealed through this survey Further surveys are being instigated, and from this it is hoped that a much wider coverage can be achieved, perhaps on all sites of Southern and Western sea of Korea and contributed to the finding of sources, stationary area of debris.
