Since ocean dumping of wastes was permitted by law in 1900, the amount of wastes dumped into the sea has increased ten times for 15 years. As a result, the dumping sites has been deteriorated so much that the pollution has become a social problem. The 96 Protocol to the 72 London Convention, which requires the contracting party's stricter control on the disposal of wastes at sea, took effect on March 24, 2006. Therefore, our country has become confronted to the situation on which it cannot delay putting a restraint on ocean dumping. Hereupon, Korea Coast Guard (KCG) initiates a dumping sites recovery program. The program is intended to curb the amount of wastes dumped at sea and to recover the polluted dumping sites. In this paper, the current status of our country's management of ocean dumping of wastes is examined and the future condition is anticipated KCG's ocean dumping management measures are also presented.

Tarballs formed by HEBEI SPIRIT oil spill observed in the south-western sea of Korea from December 27 2007. The tarballs were removed by the response party, which Korea Coast Guard became a center of organization. The amounts of removing tarballs form the sea and the coast were 0.345 tons and 1,739 tons, respectively. The number of persons, in order to remove the tar balls from the south-western sea of Korea, counted about 97,000 persons, including 25,000 volunteers. In this paper, we introduced the response methods of tarballs entering into the south-western sea of Korea such as a landing net, meshes and so on.

In the event of a marine pollution accident, Korea, which is bordered by the sea on three sides, would suffer tremendous damage. According to an analysis of marine pollution accidents in Korea, most pollutants were small fishing boats and tugboats. In particular, urgent safety measures are required due to the high incidence of marine pollution accidents caused by stranded tugboats. This study aims to decrease secondary marine pollution accidents by preparing measures to prevent accidents by stranded tugboats, the main source of pollution accidents. To this end an experiment was conducted to mark 63 locations where stranded accidents have occurred on the GPS plotters of 61 tugboats operating in Boryeong sea area. Its effectiveness was then investigated. The result showed that there was no stranded accident by the subject ship during the 20-month experiment period. As a result of survey of the captains, 36 out of 40 respondents (90%) stated that the experiment was significantly helpful in ensuring safe navigation, thus confirming its effectiveness. Various measures were proposed to prevent stranded accidents, including providing information to manufacturers and users by marking the location of grounded accidents on GPS plotters and posting the location information of unknown reefs on the official website of institution Korea Hydrographic and Oceanographic Agency.

In this article, legislational and economic meaning of Marine Pollution Prevention Law (MPPL) of North Korea was studied with review and comparison of North Korea's environmental legislation system. North Korea's MPPL is the basic legislation system against pollution activities. This law has the purpose of gaining of marine environmental protection and resources and declares mainly the marine environmental protection with little definition of action plan and means. To analyze economic achievements of MPPL, more macro- and microeconomic data of North Korea should be accumulated. However, environmental issues are relatively effective to discuss common goal of environmental protection and economical cooperation between Korea and North Korea. To prepare reunification, understanding of North Korea's MPPL is the first step for collaboration of marine environmental conservation.

The marine traffic congestion has increased due to the expansion of vessel traffic volume in Korean coastal waterway these days. Heavy traffic could bring serious marine casualties which cause the loss of human lives, properties and marine pollution in coastal area. In this paper, the probability analysis of marine casualties in Korean coast. To achieve this aim, clears up the cause of accident and examines closely the mutual relations among marine casualties, weather condition, and marine traffic volume. These casualties are classified into several patterns or the point of view of ship's size, ship's type and ship's age and its characteristics of each pattern are described In detail.

We estimated sediment pollution by the analysis of COD and AVS. We also estimated the contents of Cu, Cd, Pb, Zn in sediment of Gwangyang bay, Mokpo inner bay and Shinan Bigum coastal area from 2011 July to 2012 February. In these results of sediment COD and AVS show III level pollution in Mokpo inner bay, however Gwangyang and Shinan Bigum coast show I level pollution. The results of Igeo show over 2 on the contents of Cu and Cd in Gwangyang bay and Mokpo inner bay. It also know that Igeo can more and detail estimate sediment pollution in industrial coastal area. These results show that it is suitable to estimated sediment pollution by COD and AVS with trace metal in industrial and initial polluted coastal area rather than analysis of COD and AVS only in coastal area.

The total number of Sea Area Utilization Consultation in the environment management sea areas reviewed from 2015 to 2017 were 60. The number of development projects in the environment conservation sea areas decreased steadily, but special management sea areas increased. Development types in environment management sea areas showed that artificial structure installation was the highest ratio, followed by fishery port development and construction of habor and coastal maintenance and sea water intake and draining. By comparing the trend of water quality changes using marine environment information system (MEIS) data in the environment management areas from 2006 to 2017, COD showed no significant changes but the environment conservation sea areas increased slightly, and the concentration of TN and TP decreased. Gwangyang and Masan bays in the special management sea areas and Gamak bay in the environment conservation sea areas displayed oxygen deficient mass in the summer. As the use of development projects of the environment management sea areas are performed continuously, an analysis of the status of sufficient water quality changes is necessary for environmental impact assessment (Sea Area Utilization Consultation) in the marine environment and should be evaluated mainly for management of contamination by diagnosing thoroughly water quality effects and the pollution of sediment. Especially, the water quality goal for the purpose of designation in each of the environment management sea areas is set clearly, connection with pollution source control and the total pollution load management system (TPLMS) should be proposed and measured to reduce the amount of contaminated water.

We investigated the concentrations of acid volatile sulfide (AVS), ignition loss (IL), total organic carbon (TOC), total nitrogen (TN), and metallic elements (As, Cd, Cr, Cu, Fe, Hg, Mn, Pb, and Zn), in August 2015, to determine the spatial distribution and pollution status of organic matter and metals in the surface sediment of Jinju Bay, a spraying shellfish farming area, Korea. The concentrations of organic matter and metallic elements were significantly higher in the southern part of the bay than in the mouth and center of the bay. The C/N ratio (5.7~8.0) in the sediment represents the dominance of organic matter of oceanic origin in the surface sediment of the study area. The concentrations of AVS, TOC, and metals (As, Cd, Cr, Cu, Hg, Pb, and Zn) were much lower than the values of the sediment quality guidelines applied in Korea. Based on the results of the pollution load index (PLI) and ecological risk index (ERI), the metal concentrations in the surface sediment of Jinju Bay have a weakly negative ecological effect on benthic organisms although the sediments with high metal pollution status are distributed in the southern parts of the bay, with high dense shellfish farming areas. Thus, the surface sediments in Jinju Bay are not polluted with organic matter and are slightly polluted with metallic elements.
