  • In order to understand the impacts of the construction of artificial sea dikes on carbon cycle in Samangeum area being a closed environment after April, 2006, we had measured suspended particulate matters, particulate and dissolved organic carbon in the surface water of inner Saemangeum dike from 2003 to 2006. The significant inputs of suspended particulate matter and organic carbon were mainly occurred during the wet season which suggests that most organic matter loading is concentrated within a short period of time inside the dike. The concentrations of particulate matter and organic carbon have gradually increasing every year inside of dike from the Mangyeong river estuary to Saemangeum dike, which has been closed since 2003 after the construction of the 4th dike. The particulate organic carbon increased due to the phytoplankton blooms by eutrophication. If the large portion of particulate organic matter produced in the surface water sink to the bottom sediment, this will cause the anoxic condition in this closed environment.

  • Official Development Assistance(ODA) Project is initiated to assist a developing country economically and to promote its welfare. Support on training and information system development are the primary elements in the maritime safety field. The maritime safety information system(MSIS) of ODA projects deals with maritime safety information of developing nations and ensures an inter-operability between other systems. Therefore, it is required to develop MSIS based on the Universal Hydrographic Data Model(UHDM) of International Hydrographic Organization(IHO). In this paper, we have analyzed the current status and operational process of UHDM established by IHO. Oil spill response system was selected as an example of MSIS project and, also, considered the application results to the maritime safety field of UHDM.

  • In the present paper, the regulatory compliance on the report responsibility relating to marine pollution prevention working plan for ship recycling in accordance with the Marine Environment Management Law in Korea was examined. In addition, plans to raise the regulatory compliance based on the results of the regulatory compliance questionnaire survey and interview between the concerned parties were suggested. The result of the regulatory compliance revealed that the degree of regulatory compliance of all groups is 52.7%, the government official group is 56.5%, marine industry related group is 48.6% and ship recycling group is 48.6%. Counterplans to raise the regulatory compliance, such as public relations for the ship recycling and marine industry related group and the development of simple standardized report form were suggested based on the results of the regulatory compliance survey.

  • Almost of all impediments to enhancing ship safety and preventing vessel-source marine pollution arise from the interaction between direct and indirect factors. The direct factors come from human errors and failure in compliance with the international convention standards for the operation of cessel. The indirect factors derive from the will and attitudes of the countries taking little responsibilities with appropriate seriousness for policing their fleets. By focusing on these aspects, this paper reviews the effectiveness of existing countermasures adopted by IMO and intends to propose a new paradigm to improve the implementation capability of each nation by suggesting frameworks of maritime administration models.

  • While fishery has been continuously suffering from deteriorating economic feasibility, the amount of the deposited marine litter has been increasing due to an increased number of marine leisure tourists which are caused by an improved quality of life and five-day work week. In addition, the fishery area has been reduced by the reclamation projects and it is being destroyed by marine pollution with a variety of contaminants coming from land and sea. To protect and improve fisheries in these poor conditions, Korean governments have implemented the submerged marine litter collection projects. However, previous research results on the marine environment and resources indicate that it requires a lot of time investment to achieve tangible results of such improvement. The 300 billion won marine environment and resource investigation project has been executed since July 2004 by Korean governments, which demands strategic approaches to obtain more effective and satisfactory results before the project expires in 2013. Ocean environment research institutes and governments need to cooperate each other to gain efficient and reasonable achievement by identifying and linking related projects. This study suggests that the marine environment and resources investigation projects should run parallel with the submerged marine litter collection projects on mutually agreed research items in the identical area of the ocean to obtain cost-effective improvement of marine environment and fishery conditions.

A Study on the Improvement of the Marine Pollution Management Capacity of Local Governments - Focucing on Support by the Central Government - (지방정부 해안방제능력의 개선방안에 관한 연구 - 중앙정부의 지원방안을 중심으로 -)

  • The importance of marine pollution prevention is increasing day by day both at home and overseas. Against this context, this study proposes policy directions to forge an improved system of coastal control for local governments. I have analyzed the coastal pollution response capacity of local governments to find out how the central government can better support these efforts to reinforce capacity. For the purposes of this research, I carried out a number of case studies on large-scale marine pollution accidents that occurred at home and abroad. According to the results, I identified the implications of the coastal pollution response capacity of local governments and suggested several alternatives such as construction of step by step response system, strengthening education and training, part of human network activation, establishment of grounds for securing response resources, and establishment of dedicated department to prepare for potential future marine pollution accidents. However, as little research has been done on the coastal pollution response capacity of local governments, this work may be regarded as an experimental study to help facilitate follow-up research in the future.
