국제법의 일반원칙에 따르면, 연안국은 공해상의 범죄혐의가 있는 외국선박에 대하여 관할권을 행사할 수 없다. 공해상의 선박에 대해서는 국제법상 원칙적으로 기국이 관할권을 가지며, 공해상의 항해 자유의 원칙은 확립된 국제해양법의 원칙이기 때문이다. 따라서 공해상에서 연안국의 관할권 행사에 있어 국제법상 법리적 한계를 인식하고, 외교적 측면에서 실효적인 관할권 행사를 위한 노력이 필요하다는 점을 유념해야 할 것이다. 한편, 국제법상 해석학적 현장성의 법리나, 일부실행행위이론에 따르면, 공해상의 외국 선박에 대하여 연안국의 관할권 행사가 법리상 가능하다. 우리 해양경찰함정과 어업지도선의 공해상의 위법 외국선박의 단속에 있어 국제법상 판례를 통해 확립된 이러한 법리들을 활발히 적용하여 우리의 해상관할권을 적극 행사하도록 해야 할 것이다.

The population of small yellow croaker, Larimichthys polyactis, in the Yellow and East China Seas has decreased significantly since the mid 1970s. Several management measures have been introduced to conserve it, but population size remains low. To rebuild this population, it is now necessary to consider more effective management methods based on the stock assessment. To determine long-term population changes, fishery and biological data collected over 34 years (1969-2002) were analysed. Yearly fish length compositions were analysed for the time periods 1968 through 1970, 1978 through 1982, and 1993 through 2002; and catch data was available from 1969 to 2002. Annual population sizes were calculated based on length composition, the relationship between total length and body weight, and total landings. Analyses showed that since the 1970s, average size of harvested fish decreased; the proportion of less mature fish (smaller than the 50% maturity length, 19cm) in catches has increased and the estimated biomass has decreased significantly. Consequently, the main management recommendation is that juvenile fish need to be better protected to allow the rebuilding of resources to a more sustainable population level. This will require fish size limit, permissible mesh size, and closed area and season regulations.

To investigate the catches of squid jigging fishery, a series of fishing experiments was conducted in the high seas of the Northwest Pacific(40˚-43˚N, 150˚-155˚E) during the period of 1 August to 22 October 2005 by commercial fishing vessel. The number of 142 test fishing was carried out in the Northwest Pacific during 83days. The total catch were 47,524kg as 4 squid species and CPUE was 8.9kg/line·day. CPUE showed high values in the frontal zone during the survey. Main squid species caught from the experimental fishing were the neon flying squid, Ommastrephes bartrami(96.8%) and the boreopacific gonate squid, Gonatopsis borealis(3.2%). Dorsal mantle length of the neon flying squid were increased by the time and increasing of the hook size. Loss rate of the neon flying squid in the water showed the highest values in 28.2% compare to the others. And the loss rate of the front roller and in the air were 1.1% and 1.0%, respectively.

To investigate the fishery and fishing ground environment of red horsehead (Branchiostegus japonicus), the author analyzed the fishery data and examined the amount of catches and oceanic environment on the adjacent seas of Jeju island and East China Sea. It was turned out that the favourable season of the red horsehead fishery is the month from March to June, the main fishing ground is located in 60 mile radius from the position 32.5˚N, 125.7˚E. The bottom seawater temperature in fishing ground was shown between l3℃ and 16℃, the salinity was appeared between 33.5 and 34.0psu without the seasonal variation of the year. Concentrations of materials(e.g, NO3- and NO2-) in spring and summer time in main fishing ground were higher than any other seasons, but that of phospheric materials were lower than any other seasons. Concentrations of chlorophyll - α in the main fishing ground was the highest in spring and summer at the surface layer, but the vertical profile of the chlorophyll - α concentrations in all seasons were not variable at bottom layer. Mean density of zooplankton abundance according to the vertical structure was higher and much stable in summer and autumn than spring and winter.

The state-of-art third generation wave prediction model WAM was applied to the Korean seas for a winter monsoon period of January 1997. The wind field used in the present study is the global NSCAT-ERS/NCEP blended winds, which was further interpolated using a bi-cubic spline interpolator to fine grid limited area shallow water regime surrounding the Korean seas. To evaluate and investigate the accuracy of WAM, the hindcasted wave heights are compared with observed data from two shallow water buoys off Chil-Bal and Duk-Juk. A detailed study has been carried with the various meteorological parameters in observed buoy data and its inter-dependency on model computed wave fields was also investigated. The RMS error between the observation and model computed wave heights results to 0.489 for Chil-Bal and 0.417 for Duk-Juk. A similar comparison between the observation and interpolated winds off Duk-Juk show RMS error of 2.28 which suggest a good estimate for wave modelling studies.

Recently there have been growing disputes between neighboring local governments over jurisdictional rights or property rights of ocean resources in Korean coastal waters. The reasons for the disputes come mainly from the increasing interests by local governments that begin to see the oceans as the source of resources and wealth. The maritime dispute is more complicated and sticky than the inland ones, and requires not only socio-economical but political approach, therefore sometimes demanding a plenty of time and endeavor. Also coastal states that have suffered from maritime boundary problems have different issues under the different environment and historical background. For Korea, as the maritime boundary issue has very recently soared to the surface, though it was latent for the period as long as 20 years, we have just taken steps toward an institutional approach on it, seemingly more to go to reach an agreeable resolutions to the disputes. This paper highlighted the issues surrounding the maritime boundary on the sea surrounding Korean peninsular after addressing the current situation of the boundary disputes. It will help explore and assess the possible solutions to the boundary conflicts over the lateral boundary between local governments.

The wheelhouse front glass of a Fore-Bridge-Ship (Ro-Ro Ship) was broken by the shipping of water in rough seas, and then the flooding of seawater into the wheelhouse caused the uncontrollable condition of the ship. The hull which was entered into the floating condition rolled severely, and the heavy rolling caused secondary damage such as the collapse of a lot of cargo. It was an incredible accident because the height of bow freeboard was about 2.5 times higher than the standard height of minimum bow freeboard regulated by the International Load Line Convention(1966). And it would be also difficult for navigators to imagine a great deal of seawater flooding into the wheelhouse because the front glass was positioned at about 20m height above the sea surface. In this paper, we carried out the evaluation for the safety navigation of the Fore-Bridge-Ship numerically against ship's speed and encountering angle to the wave in each sea state of rough sea, by using the integrated seakeeping performance index (ISPI) which is able to evaluate synthetically the safety operation of ships. And then the problem on the application of the past criteria proposed as the safety navigation of a merchant ship was clarified by inquiring the dangerousness of the shipping of water at her bow deck, which caused the breakage of the wheelhouse front glass.

It is argued that conventional behavior of government, industry, and the public in managing the seas is dysfunctional and must change. Industry manipulation of government regulatory processes, the public complacency that allows it, and its consequences are discussed. Resolving this problem will reqire industry to embrace a code of environmental ideals such as the Coalition for Environmentally Responsible Economies(CERES) principles. A new emerging 'corporate environmentalism' is discussed.

Uederwater ambient noise was measured at the set net in the Neung-Po Eay. The environment characteristics depend upon oceanographic conditions of sound propagation and its implication on the source of ambient noise. The results of measurement and analysis were as follows: 1. The frequency of the maximum noise level of two passenger. vessels was around 300 Hz. The spectrum level of the fast vessel (the Air-Ferry) was lower than the little slow vessel (the Olympic) between 50-150 Hz in frequences. 2. The spectrum level of the surface in the playground of the set net was lower than the deeper water till 500 Hz, but over that frequency the level was getting lower as the depth was deep. 3. The spectrum level outside the bag of the set net was greater than the inside between 50 and 700 Hz, but over 1,500 Hz the level inside the bag was higher than the outside. 4. The spectrum level of the outside of the breeding tank was higher than the inside in the daytime. However at night opposite phenomenon occurs.

Arctic sea ice as an indicator of climate change plays an important role in controlling global climate system. Thus, accurate observation and prediction of Sea Ice Concentration (SIC) is essential for understanding global climate change. In this study, we aim to improve the prediction accuracy of SIC by using machine learning and Regional Climate Model (RCM) data for a more robust method and a higher spatial resolution. Using the CORDEX RCM and NASA SIC data between January 1981 and December 2015, we developed three statistical models using Multiple Linear Regression (MLR), Support Vector Machine (SVM), and Deep Neural Network (DNN) which can deal with the non-linearity problem, respectively. The DNN model showed the best performance among the three models with the significant correlation between the predictive and observed SIC (r=0.811, p-value < 0.01)and the Root Mean Square Error (RMSE) of 0.258. With deeper considerations of the polar fronts and the characteristics of ocean current and tide, the DNN model can be applied for near future prediction of Arctic sea ice changes.

이 연구에서는 최근 5년(2010～2014년) 동안의 데이터를 이용하여 우리나라의 풍랑특보 분포 특성에 대하여 분석하였다. 풍랑특보는 우리나라 주변 해역을 항해하는 선박 및 해양 구조물 등의 안전에 큰 영향을 미치므로 중요한 의미를 가진다. 풍랑특보는 한반도의 동측 즉, 동해남부 및 동해중부 해역, 남해동부 해역에서 많이 나타난다. 이 결과는 온대저기압의 이동과 발달, 계절풍의 세기 등과 밀접히 관련되어 있 다. 그리고 풍랑특보는 12월에 가장 많고, 1월과 3～4월에도 높은 빈도수를 보인다. 계절로 구분해 보면, 겨울 〉봄 〉가을 〉여름의 관계를 확 인할 수 있는데, 이들 결과는 온대저기압의 발생 및 발달, 계절풍의 세기 차이 등에 의한 것이다. 앞바다와 먼바다의 월별 풍랑특보 분포에 대 하여 통계 분석한 결과, 양자는 강한 양의 상관관계가 있음을 확인하였다.
