연안해역은 육상환경과 해양환경이 상호작용하는 완충지역으로서, 양식어장, 항만, 해수욕장 등으로 이용되고 있다. 남해안과 같은 연안해역은 기초생산력이 아주 높고, 해면양식업에 적합한 지형적 여건을 갖추고 있어 옛부터 어패류 양식장으로 널리 이용되고 있다. 연안환경 특성에 따라 크게 2가지 유형 즉, 진해만과 같이 외부 부하량 증가로 적조가 상습적으로 발생하는 부영양화된 해역, 한산ㆍ거제만과 같이 외부 부하량 유입이 적고 기초생산력이 낮은 빈영양 해역으로 나누어진다. (중략)

The purpose of this study is to find seasonal variation of the water circulation in the Chenbuk coastal sea region. Chenbuk coastal sea is investigated with use of a robust diagnostic numerical model. Water circulations in four seasons are calculated diagnostically from the observed water temperature and salinity data and wind data from Kunsan mereorologcal station.

This study examines the efficiency of safety management measures taken in coastal waters to prevent coastal accidents. Recent years have witnessed about 800 cases of large and small coastal accidents in coastal waters annually. On average, these accidents have been responsible for 129 deaths annually, Thus, there is a need for effective preventive measures. Accordingly, the Korea Coast Guard enacted the Coastal Accident Prevention Act in 2014 and has cooperated with related organizations, such as local governments and the Ministry of Oceans and Fisheries, to safely manage coastal waters. However, compared to the rapid increase in human coastal activities, coastal accidents continue to occur due to the lack of a safety mindset among the Korea Coast Guard, a lack of public safety awareness, a lack of safety management facilities, and poor interest from related organizations, among others. This study examines the conditions and problems faced with regard to safety management in coastal waters based on recent coastal accident data, and analyzes foreign coastal waters safety management cases. Various methods to improve the safety management efficiency in coastal waters are proposed, such as enhancing the safety mindset and capabilities of the Korea Coast Guard, strengthening cooperation among related organizations, increasing the role of local governments, expanding and strengthening safety management facilities by applying new technologies, inculcating a culture of maritime safety, and activating private-public collaborative governance.

This study aims at proposing and developing the coastal management policy tool package contingent upon coastal community circumstance so that coastal regional government may enhance the efficiency of coastal administration and reestablish the coastal region master plan systematically. The 8 coastal policy tools of the already-tested U. S. coastal region government will be utilized as the new alternative on behalf of the Korean coastal region government. According to the result of experts survey, these tools especially can be used effectively in the tourism, disaster, restoration, and scenary coastal function types. Although this study is exploratory, it will be expected to contribute as the basic survey results of the successive research and coastal region policy development in Korea.

Since being launched for ocean observing in 1997, the SeaWiFS sensor has supplied data on ocean chlorophyll distribution and environmental conditions of the atmosphere. Until now, a lot of SeaWiFS data have been archived and utilized for ocean monitoring and land observation. The SeaWiFS sensor has 1km spatial resolution, therefore, it is difficult to obtain data at the coastal zone. Since atmospheric correction algorithms at the coastal area have not been confirmed for chlorophyll algorithm, the ocean color data analysis for coastal zone is not common. In particular, domestic coastal areas have high suspended sediments concentrations and higher absorption influence of colored dissolved organic matter (CDOM), released from in-land, than open-sea. Thus, a useful algorithm for analysis of chlorophyll distribution in domestic coastal areas has not been developed. In this study, empirical algorithms, using data from the ocean color sensor, were developed for monitoring of chlorophyll distribution of coastal areas. In the process of the development of the algorithms, we can find that the red band (665nm) should be used for analyzing of domestic coastal areas near the Yellow Sea.

해상 교통량 증가에 따른 연안해역 해상교통밀집도가 증가되고 있다. 그러므로 해상교통안전관리를 위해 실 해역의 해상교통패턴을 파악하여 해상교통지수를 평가하는 것이 중요하다. 분석대상해역의 실제 선박위치, 속력, 침로를 고려한 CPA-TCPA분석은 통계적인 선박데이터에 의한 분석보다 해당해역의 실제적인 VTS영향 등 교통환경을 반영한다. 본 연구에서는 횡간수도와 완도진입수로의 항로가동률을 분석하고, 해당 해역에서 교차되는 선박들의 CPA, TCPA 등을 분석하여 해상교통안전지수를 평가하고자 한다. 또한 산출된 해상교통안전지수를 해당 해역의 통계적인 해상교통안전지수와 비교 및 분석하고자 한다.

황해의 남동부에 위치한 한국 남서 연안해역은 남해와 인접한 해역으로 황해저층냉수, 황해난류수, 연안수, 양자강 희석수가 영향을 미치고 있으며, 이들 수계간에 형성되는 수온전선역은 좋은 어장을 형성한다. 또한 이 해역은 주요 수산자원의 어장 및 회유환경 그리고 해조류양식 등과 관련하여 해양학적ㆍ수산학적으로 매우 중요한 해역이다. 조석전선이 해양의 1차 생산자인 식물플랑크톤의 분포 및 성장에 큰 영향을 주는 것으로 밝혀지고 있다(Bowman and Esaias, 1977). (중략)

연안지역의 개발 및 이용으로 오염물질의 발생량이 증가하게 될 뿐 아니라, 발생된 오염물질은 인근 하천 및 해역에 의한 방류 등으로 연안해역의 환경을 오염시키고 있다(통상산업부 등, 1996). 연안에서 발생하는 오염물질의 하천유입, 해양방류 및 해상투기 또는 오염물질 유출사고가 연안환경에 미치는 장ㆍ단기적인 영향을 파악하기 위해서는 대상해역의 흐름을 고려한 오염물질의 이송ㆍ확산을 적절하게 예측하여야 한다(National Research Council, 1994). (중략)

Numerical models have been widely used to understand the structure of coastal currents and the transport mechanisms in regard to the fate of pollutants. This study focuses on the development of a three-dimensional model of coastal circulation and mass transport. The model was used to calculate coastal currents and temperature distributions of the thermal plume discharged from a power plant. The model results were compared with field-observed data. They showed the relatively good agreements with the data. The model can be used to estimate the currents and its mass transport in coastal waters.

연안해역은 육지의 대륙붕을 따라 존재하기 때문에 육지로부터 담수의 영향을 크게 받고 영양염이 풍부하고 수심이 얕기 때문에 저층에 침강했던 영양염도 쉽게 유광층으로 이동하는 등 생물활동이 활발한 해역이다. (중략)
