  • The distribution and composition of marine floating debris were recorded from a training ship 'Kyeongyang' of Gangwon Provincial University at May 19-29, 2004 and Aug.24-31, 2004. The sampled area is the middle part of East Sea of Korea(the coast of Gangwondo and region of Ulleung island and Tokdo), divided into 27 unit segments on survey areas. Debris fabrication materials were categorized with 6 items using the following; styrofoam, paper & cardboard, net & rope, vinyl & plastic, floating metal & glass, man-made or natural wood. From the investigation on May,2004, total numbers of marine floating debris in the middle part of the East Sea of Korea was 996 individuals. The No. 1 and No. 2 unit segment located at south-west region of Ulleung Island showed higher density than others. The styrofoam and vinyl & plastic accounted for 72.8% of all debris fabrication materials. From the investigation on August, 2004, total numbers of marine floating debris in the coast of the Gangwondo of Korea was 2,473 individuals. The No. 13 and No. 14 unit segment located at the vicinity of Samcheok showed higher density than others. The styrofoam and vinyl & plastic amounted to 76.1%. In the coast of the Gangwondo, the vinyl & plastic showed the highest density of 6 items were 41.3% and 68.0% on May and August, respectively. The total numbers of marine floating debris on May and August were 3,399 individuals. Vinyl & plastic accounted for 59.4%(2,019 ind.) among all debris, next styrofoam 15.8%(537 ind.) and wood 11.2%(379 ind.).

  • (1) This study was carried out to obtain seasonal fluctuations of marine debris in 5 beaches near the Southern Coast of Korea during May, 1999 - April, 2000. The results are as follows: 1. The density of marine debris was remarkably highest at Namhae beach among 5 beaches. The major part of debris in the beach was styrofoam, with the density of 348.5${ea/km}^2$. But, it was Songjung where the largest amount of resin pellets existed. 2. The composition of styrofoam consisted of 51% of the marine debris, wood& papers was 11%, resin pellets & plastics were 8% and others were 16%. 3. Seasonal fluctuations irregularly change in each beach, but the amount of resin pellets were found to be large only in September. It is estimated that resin pellets are beached upon the coastal beaches by the strong warm currents(Tushima currents) during the summer season. 4. Debris fabrication materials that were found had most of parts made up of PE 71.2%, PP 21.2% and EVA 7.7% through these surveys. 5. In the polluted state, the medium one among the 3 specifications(o1d, medium and new state) occupied 88.5% or so.

  • A series of surveys are performed to evaluate the abundance, composition and distribution of marine debris on the sea bed around the Busan port. In order to set up a master plan for the marine environmental pollution the relevant maritime authority must understand how many and w㏊t kinds of marine litters are distributed on the sea bed. At first we planed to survey areas divided regularly according to the coast line but there were many sea going vessels and fishing boats. So we selected and surveyed the around area where there were no sea going vessels or fishing boats.The obtained results are as follows: 1. The mean values of litters in number and weight are 5.8 pieces/㏊. and 3.5㎏/㏊. respectively. 2. The highest density in terms of number are vinyl and plastic item, and in weight are fishing gear and ship articles. 3. The nearer to the shore we surveyed the more we collected in terms of the density of marine litters in number and in weight per hectare. 4. Eel pot, oiled waste, rope, others, other pot and net of fishing gear litters in number were 59.9, 22.7, 7.9, 4.5, 3.1 and 1.9% respectively. 5. There is no relationship between the amount of fish caught and the amount of marine debris.

  • We investigated meiofaunal biofouling (40-1,000 ㎛) on stranded marine plastic debris (hereafter MPD) collected from 8 coastal areas highly affected by plastic pollution located in the southern part of Korea during June, 2021, in order to analyze the abundance and composition of MPD associated organisms. A total of eight shapes of MPD was collected and classified into four types of plastics (LDPE, PET, PP and EPS) based on Resin Identification Coding System. Meiofounal biofouling was identified into 35 taxa belonging to 11 phylum, 10 classes and 12 order, and were numerically dominated by harpacticoids (EPS: 21.6%, PP: 27.1%), nematodes (LDPE: 23.2%) and foraminiferans (PET: 29.6%). Surface area of MPD was negatively correlated with abundances of organisms on the plastic debris (r = -0.487, p < 0.05, n = 24), indicating that abundances (avg. 3,225 inds. 0.1 m-2) on the smallest area of PP debris (avg. 0.0208 m2 ) were higher than those (avg. 50 inds. 0.1 m-2) on the largest area of LDPE debris (avg. 0.4029 m-2). Whereas, there was no correlation between surface area of MPD and the number of taxa on the debris (r = 0.147, p = 0.49, n = 24). These results showed that higher abundances of meiofaunal biofouling were observed on the PP material debris than those on the other debris collected from eight hot spots of the southern coastal waters in Korea, associated with not only polymer type and surface area of the PP debris, but also possibly surface microstructure of the PP debris.

  • 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 $100{\pm}2m$ 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 $km^2$. 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 ills an 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 achived, perhaps on all sites of Southern and Western sea of Korea and contributed to the finding of sources,stationary area of debris.

  • 2013년 가을, 한국 통영의 13개 해변에서 해양쓰레기의 풍도와 조성을 조사하였다. 대형쓰레기(25 mm 이상)의 풍도는 평균 약 30개/$m^2$, 소형쓰레기(1 mm-25 mm)의 풍도는 평균 26,971개/$m^2$로서 한국의 다른 지역이나 전세계 다른 지역에 비해 매우 높은 편이었다. 스티로폼, 경질플라스틱, 섬유, 금속, 유리, 목재, 기타 등 7개 재질로 구분했을 때 대형쓰레기 중 스티로폼의 갯수가 차지하는 비율은 약 75%, 소형 쓰레기에서는 약 98%였다. 대형 스티로폼 쓰레기 중 원래 부피의 50% 이상이 남아 있는 '완제품' 쓰레기들을 양식용 부자와 기타 완제품 쓰레기로 구분했을 때 양식용 부자가 차지하는 비율은 갯수로 93%였다. 결국 조사된 해변들에서 쓰레기로 인한 해변 오염은 매우 심각한 수준이며, 쓰레기의 발생 원인의 대부분은 양식장에서 사용되는 스티로폼 부자인 것으로 밝혀졌다. 통영 지역은 한국에서 굴 양식장이 가장 많은 곳이므로 굴 양식장의 스티로폼 부자 쓰레기 관리를 개선하는 것은 통영뿐만 아니라, 다른 지역의 해변 오염을 예방하는 데도 중요한 것으로 보인다.

  • In order to estimate the densities and composition of floating marine debris (FMD), a sighting survey was conducted from July 1st to July 14th, 2009 in the East China Sea (ECS) using a training vessel "Kaya (1,737 ton)" of Pukyong National University. The sampled zones are divided into 5 transects by observation day during the survey days and the densities and composition in each transect were calculated using the numbers of item per $km^2$. The results of distribution of FMD are as follows: 1. During the surveys, a large variety of FMD was discovered and highest densities were found in the Central East(CE) of the East China Sea(ECS) (48.2 items/$km^2$), whereas densities in the less populated transects in Okinawa(OK1, OK2) were comparatively low(3.5 ~ 4.9 items//$km^2$). 2. Among the classified 6 items, styrofoams(Styro) were most abundant and ubiquitous(10.3 items/$km^2$, 53% of the total number), except OK2 area. Next abundant item was vinyl and plastics called V & P(4.9 items/$km^2$, 25%). Above 2 items of the major proportion of FMD accounted for 78% of the total number of FMD observed through this study. 3. The percentages of manufactured plastics(Styro and V & P) found in the Seas near Korean Peninsula were varied from 87.2% to 69.8%. It was recognized that polluted level is middle value among them.

  • Floating debris was observed using a training ship, KAYA, of Pukyong National University with cruising speed of about 10-12 knot during July 12~25, 2003. The area sampled was the East Sea enclosed by 3 nations, namely, Korea, Japan and Russia, and was divided into 68 unit segments on survey routes [Fig. 1]. Debris fabrication materials were categorized with 6 items, e.g., man-made or natural wood items, paper and cardboard, nylon rope, styrofoam, vinyl and plastic, floating metal and glass containers. All identified items within $100{\pm}10 m$ wide band were recorded but ignored if beyond this boundary. The results of this study are as follows: 1. The average numbers of debris per unit area, $1km^2$, were found as 16.3 pieces (items) in the sea. 2. The highest densities of numbers, $32.3pieces/km^2$, were discovered in vicinity of the Oki strait of Japan, area of 'NEK' in Fig. 1. 3. Especially, styrofoam item only was composed to 63.6% of all in the sea of 'SD', located in the southern part of Dokdo Island, Korea. The item seems to be derive from the Southern Sea of Korea. 4. Therefore, comparing the distribution of debris numbers (the results of above 2 and 3) with flow patterns of Kuroshio currents, it was shown that their relation was good agree each other. Further more surveys are being conducted and a much wider coverage can be achieved with other countries, then it can be obtained that the East Sea is polluted to some extent, where is the origin of debris, and the finding of floating routes and stationary sea.
