Sea level rise due to climate change is an increasing concern for the international community, and especially for coastal States. In case of regression of the coastal line or inundations of maritime features, including islands, the questions of whether coastal States are under an obligation to redraw their baseline and the outer limits of their maritime jurisdiction and of whether the existing maritime boundary treaties should be terminated are raised. This article reviews the arguments raised by the Small Island Developing States, International Law Association, and International Law Commission and suggests a solution within the current legal framework of the Law of the Sea through an interpretation of the existing provisions of the UNCLOS focusing on the legal issues relating to the Law of the Sea.

The Yellow sea, as described in article 123 of UNCLOS, is semi-enclosed sea surrounded by the Republic of Korea, the People's Republic of China and North Korea. In addition, the Yellow Sea is one of the 66 large marine ecosystems as it contains large amounts of marine resources. According to article 194 of UNCLOS, states should be aware of rights and duties with respect to the protection and preservation of the marine environment to be engaged with countries directly as regional entity or indirectly. Therefore, the legal blank is urgent in terms of trans-boundary environmental pollutant issues. The UNDP has conducted a project called Yellow Sea Large Marine Ecosystem (YSLME) which has reached the 2^nd phase. The project has some notable achievements, namely performing joint activities on analysis of diagnostic trans-boundary issues in collaboration with China and South Korea, developing a strategic action plan based on TDA, and establishing regional strategic action plan. However, on the other hand, the project could not reflect the full participation of North Korea as a state party. As a result, the project has a limitation on effective implementation of RSAP. Therefore, this study focuses on the suggestion of a legally-binding trilateral treaty as a blue print for the next, 3^rd phase of the project. By analyzing the best practice of the Wadden Sea Trilateral Treaty case, the study verifies the validity of legislative measures on establishing and managing a legally-binding trilateral YSLME Commission. By suggesting a three phase treaty, incorporating a joint declaration by establishing the commission, the signing of the treaty, and formulating an umbrella convention and implementation arrangement, the study expects to guarantee the consistency and sustainability of the trilateral treaty regardless of political issues pertaining to North Korea.

Coastal zone management indicators are being used as an important means of decision making in the process of policy establishment for integrated coastal management and implementation, and these indicators are very useful tools that enable the evaluation of the coastal zone management from an integrated perspective, the understanding and analysis of interactions according to each department. Accordingly, most of organizations in international society and advanced coastal states tend to develop coastal zone management indicator system in order to check current coastal environment, social and economic status, also to grasp effectiveness of the coastal zone management policy. In this research, therefore, the characteristics of coastal zone management indicator system was drawn through understanding of strength and weakness, and conducting comparative analysis of the coastal zone management indicator system according to each level having classified domestic and international coastal zone management indicator system into three aspects at large: natural and environmental aspect; social and economic aspect; and network aspect. As a result, following features were drawn as the common characteristics among the cases in the advanced coastal states: the management means for realization of sustainable coastal zone management; scientific decision making tools for various stakeholders; evaluation means for effectiveness of coastal zone integrated management; and dualization of coastal zone management indicator system; etc. Lastly, based on these common values revealed in the domestic and international coastal management indicator system, a suggestion for correct establishment of the domestic coastal management indicators was proposed in the regional aspect.

Distribution characteristics of phytoplankton community were investigated by HPLC and flow cytometry in Jeju Strait and the Northern East China Sea (NECS) in May 2004, in order to understand the relationship between physical environmental factors and distribution pattern of phytoplankton communities. Based on temperature and salinity data, three distinct water masses were identified; warm and saline Tsushima Warm Current (TWC), which is flowing from northwest of Jeju Island, warm and low saline water at the center of Jeju Strait, which is originated from China Coastal Water (CCW) and relatively cold and high saline water originated from Yellow Sea at the bottom of the Jeju Strait. At Jeju Strait, less saline water (<33 psu) of 15 km width occupied surface layer up to 20 m which located at 20 km offshore and strong thermal front between warm and saline water and cold and less saline water was found in the middle of the Jeju Strait. Vertical transect of temperature and salinity at the NECS also showed that low saline (<33 psu) water occupied the upper 20 m layer and cold and saline water was present at the eastern part. Chl a was measured as $0.06{\sim}3.07\;{\mu}g/L$. Spring bloom of phytoplankton was recognized by the high concentrations of Chl a at the low saline water masses influenced by the CCW and subsurface chlorophyll maximum layer appeared between $20{\sim}30\;m$ depth, which was at thermocline depth or below. Abundances of Synechococcus and picoeukaryote were $0.2{\sim}9.5{\times}10^4\;cells/mL$ and $0.43{\sim}4.3{\times}10^4\;cells/mL$, respectively. Dinoflagellate, diatom and prymnesiophyte were major groups and minor groups were chlorophyte+prasinophyte, chrysophyte, cryptophyte and cyanophyte. Especially high abundance of dinoflagellate was identified by high concentration (>1\;{\mu}g/L$) of peridinin at the bottom of the thermocline, which showed an outbreak of red tide by high density of dinoflagellates. Abundances of picoeukaryote in Jeju Strait were about $5{\sim}10$ times higher than abundance measured in Kuroshio water and showed a good correlation with Chl b (Pras+Viola), which implies the most of population of picoeukaryote was composed of prasinophytes. Prochlorococcus was not detected at all, which suggests that Kuroshio Current did not directly influenced on the study area. Based on the strong negative correlations between biomass of phytoplankton (Chl a) and temperature+salinity, the primary production and biomass of phytoplankton in the study area were controlled by the nutrients supply from CCW.

In order to understand microbial ecosystem in the fast china sea and Yosu coastal sea horizontal distributions of bacterial flora, Vibrio spp., coliform group, temperature, and salinity in this sea area, were studied 42 sampling stations during 6th-l4th August, 1992. From the results, salinity and temperature were $24.64\~33.78\%_{\circ}$ and $22.53\~29.18^{\circ}C$, respectively. As the open sea far from land goes on, salinity became low while temperature became high. Viable cell counts of bacteral flova, Vibrio spp., and roliform group in Yosu coastal sea water were $1.0\times10^2\~3.0\times10^4/ml,\;0.2\times10\~9.0\times10^3/ml,\;and\;0.3\times10\~3.0\times10^3/ml$ while those of these in the open sea water were $0.4\times10\~2.0\times10^3/ml,\;0.8\times10\~3.0\times10/ml,\;and\;0.9\times10\~1.3\times10/ml$, respectively.

동중국해 북부에서 쿠로시오의 경계역으로 확장된 중국대륙 연안수가 주변의 북상 난류역에 의해 포획된 후 고립되는 현상이 1999년 및 2003년 NOAA 위성영상에 포착되었다. 1999년의 경우 cold core eddy는 약 2개월간 존재(5월초～6월 하순)하였고, cold core의 중심 수온은 15～20℃로 주변해역의 17～23℃보다 2～3℃ 낮게 나타났다. 1999년 5월 7일 획득된 SeaWiFS 위성자료로부터 추정된 클로로필 α 분포는 1999년 5월 6일부터 획득된 NOAA 위성수온 영상에 나타난 cold core eddy의 주변 가장자리 해역에서 비교적 높게 나타났다. 2003년 경우 2월 중순에 cold core의 수온은 9～10℃c였으며 직경 150km 정도였다. cold core의 수평규모는 50m 등수심 분포와 유사하게 나타났다. 이어도를 중심으로 동계 및 춘계에 나타나는 cold core eddy의 형성 메카니즘은 중국대륙 연안수와 쿠로시오 난류가 만나는 경계역에서의 힘의 균형과 계절풍 조건, 해저 지형 분포와 밀접한 관계성이 있는 것으로 사료된다.

On the high seas, under international law, a ship is subject to the jurisdiction of the state whose flag she flies. Vessels of any flag are free to navigate the high seas without interference from other states. Thus, there are certain limits of coastal state's exercising law enforcement jurisdiction over a foreign flag vessel on the high seas. However, there are exceptions to exclusive flag state jurisdiction. One of them is the theory of constructive presence. The other is theory of partial execution. Korea Coast Guard's law enforcement authority should be exercised more actively based on those theories supported by the international cases.
