해양 신 재생에너지 개발에 의해 생태계에 미치는 영향을 최소화하기 위한 방안을 모색하기 위하여 환경변화 사례와 예측하였다 해양에너지의 개발은 필수적으로 해양환경 및 생태계에 변화를 초래하여 조력발전시설의 경우 조간대에 서식하는 저서생물의 종다양성을 감소시키고 철새 등의 조류의 종수 및 개체수의 변화를 가져오고 조력 및 조류발전 터빈시설은 수생생물의 기계적 충돌에 의한 사망률을 증가시킨다 이러한 해양 신 재생에너지의 개발과 더불어 생태계의 영향을 최소화하기 위한 조사 및 연구가 병행되어야 개발 후 상용화단계에서 가장 합리적인 자연보전의 방안을 제시하고 지역사회와의 갈등을 최소화 할 수 있는 과학적인 자료를 도출 할 수 있다.

Many countries have established and implemented marine ecosystem management plans to solve various problems arising from excessive development and use of marine and coastal areas. In this study, network analysis was applied to compare and understand marine ecosystem management's direction and characteristics in Korea and other maritime countries. The results showed that the words 'strengthen,' 'promote,' 'improve,' and 'establish' were the keywords used a lot in domestic and foreign marine ecosystem management plans. Establishing a foundation for marine ecosystem management, establishing international cooperation and partnerships, and strengthening climate change adaptation was commonly included. However, there were some differences in detailed management plans. In foreign countries, it aims to present management measures for certain species and improve the existing institutional foundation. Still, in Korea, it aims to strengthen the comprehensive management of marine life and establish an institutional foundation for marine ecosystems. This study is expected to help understand the direction of domestic and overseas marine ecosystem management and establish a domestic marine ecosystem management plan in the future.

The Korea Maritime Environment Corporation is conducting a comprehensive survey of the national marine ecosystem under the commission of the Ministry of Oceans and Fisheries (MOF) to ensure continuous use of the ocean, preserve and manage the marine ecosystem. The survey has set major peaks to investigate changes in the marine ecosystem around the Korean Peninsula. However as the peak has been set around the coast, it is necessary to expand the scope of investigation to encompass offshore areas. Meanwhile, the Aids to Navigation Division of the MOF supports a comprehensive national marine ecosystem survey providing photographs of fouling organisms during the Aids to Navigation lifting inspection, however, the photographs are provided only in consultation with the Korea Maritime Environment Corporation. Therefore, a study was conducted to generate information on fouling organisms using deep learning-based image processing algorithms by the lifting Aids to Navigation and dorsal buoys so that Aids to Navigation could be used as the major component of a comprehensive national marine ecosystem. If the Aids to Navigation are used as the peak of the survey, they could serve as fundamental data to enhance their own value as well as analyze abnormal marine conditions and ecosystem changes in Korea.

저서동물 군집조사는 먹이사슬이나 먹이망 등 해양생태계의 역학관계를 이해하는데 필수적으로 이루어져야 할 부분이며, 환경 변화가 해양생물에 미치는 영향을 평가하거나 생태계 변화를 예측하는데 가장 효율적인 조사방법이라고 본다. 바다목장화를 위해서는 우선적으로 연질기저 저서생불군집의 특징을 파악하여 생태계의 구조와 물질순환에 관한 기초적 자료를 제공할 필요가 있기 때문에, 본 조사는 저서환경에 대한 자료 축적 및 생태계 변동에 대한 감시 차원에서의 조사를 수행하였다. (중략)

The marine ecosystem survey investigates and analyzes multi-parameters at various times from various sites. Therefore, it is very difficult to analyze the complex ecological data of multi-items effectively, and it is more difficult to identify the current status and diagnose the problems of ecosystem through data analysis. Therefore, this paper aims to provide an example of interpretation of complex ecological data through analysis of distribution characteristics and outliers of ecological survey data. The main contents of the study are to elucidate the background levels of coastal ecosystem parameters considering the distribution characteristics of data, and to establish ecosystem monitoring indicators and an adaptive management system for the coastal waters in Korean Peninsula. The data used in this paper are based on the coastal ecosystem survey of the National Marine Ecosystem Monitoring Program conducted by the Ministry of Oceans and Fisheries (MOF) and the Korea Marine Environment Management Corporation (KOEM), and the major citations are from year 2015 to 2017. This article is a preliminary study to establish the above processes and the final result will be derived in 2020 when the coastal ecosystem survey is completed three times along the Korean coast.

해양생태계로 유입되는 화학물질의 총합적인 평가 및 관리를 위해서는 동 화합물의 해양환경중의 거동 및 운영, 생태계에의 영향, 관리방안에 따른 화학물질의 변화 예측 및 리스크 평가 등을 행할 필요가 있으며, 이를 위하여는 화학물질에 대한 생태계 모델이 유용한 수단이 될 수 있다. 본 연구에서는 여러 화학물질에 적용할 수 있으며, 지역특성, 존재 데이터 상황, 대상 수산물의 특성을 고려하여 여러 상태함수 및 프로세스의 추가와 삭제가 가능한 3차원 생태계 모델(EMT-3D)을 사용하여 해양환경중의 PFCs 관련물질을 대상으로 그 적용성을 검토하였으며, 민감도 분석 및 시나리오 분석을 행하여 영향인자를 판별하고 대안에 따른 영향을 평가하였다.

It has been mown that the global warming has an effectet on marine ecosystem and marine environments. Then, fisherman's activity and fishing production were decreased by changing of marine plankton composition and increasing of harmful marine organisms such as jellyfish, starfish and green laver bloom. Harmful red tides algae bloom and the deserted sea bottom often occurred due to increasing of sea water temperature and sea level rising in Korea. In this report, the cause and mechanism of the global warming phenomenon and it's effect on marine environment and marine ecosystem were introduced, and measures against global warming were suggested

As researchers can modify environmental factors to fit the purpose of an experiment in monitoring marine ecosystem using enclosed experimental ecosystems, which is a strong advantage of them, mid-sized enclosed experimental ecosystems (mesocosm) are widely used in the world in basic ecology such as trophodynamic study and applied ecology such as the toxicity test of various chemicals and monitoring of ecosystem changes against marine pollution. Application of the mesocosm in the field has a merit to get more reliable result than that from the experiment in the laboratory. However, the result from the mesocosm study in marine ecosystem is very limited in Korea. Mesocosms which had been used in the marine ecological studies in both foreign countries and Korea were summarized, and application of them to the future study in various research field was suggested in this review paper.

산불의 발생은 산림 내에서 낙엽, 낙지, 초류, 임목 들의 연소로서 산불재 및 질소, 인 ,칼륨 등의 식물 영양염류와 토사 등이 산지에서 이탈되어 하천으로 쉽게 유입될 수 있으며, 산지와 해양이 인접한 지형에서는 하천에서의 자정작용 없이 곧바로 해양으로 유출되어 해양생물의 생태계에 직접 영향을 미칠 수도 있다. 해양 생태계에서는 하천의 오염원 유입으로 인하여 일차적으로 강 하구의 고착생물 즉 해조류들에 영향을 줌으로써 해양환경 오염에 대한 indicator 생물로서 이들 해조류를 많이 이용하고 있다. (중략)
