내수란 영해기선의 육지측 수역으로 연안국의 주권이 미치는 수역이며, 다만 직선기선을 채용하여 새로이 내수로 편입된 곳에서는 연안국의 주권과 함께 외국선박에게는 무해통항권이 인정된다. 특히, 우리나라는 서남해안에 직선기선을 채용하여 무해통항이 인정되는 넓은 내수를 보유하고 있는데, 어업 안전 환경 안보 등 연안 이익을 보호하기 위해 내수를 이용하는 외국선박을 적절히 관리할 필요가 있다. 또한, 영해의 경우에도 연안국의 주권이 미치는 수역으로 연안국의 주요 이익의 보호를 위해 매우 중요한 수역이다. 최근 내수나 영해에서 무단정박 정류하는 외국선박과 충돌사고가 빈번히 발생하여 우리나라에 큰 위협이 되고 있다. 이에 이 논문은 우리나라 내수 또는 영해에서 무단으로 정박·정류한 외국선박의 충돌사고에 관한 사례를 분석하고, 외국선박의 내수 및 영해 통항에 관련된 국내외 법체계를 확인하고 고찰하여, 내수 및 영해에서 외국선박의 무단정박은 무해통항요건을 위반한 것으로, 관련 법률에 따른 처벌가능성을 제시하였고, 내수 및 영해통항 및 정박에 관한 바람직한 법제도 정비방안을 제시하였다.

The introduction of coastal vessel traffic services enables vessels in coastal waters to navigate in safety or to get her position with ease and prevents the vessel from becoming cause of casualties. But it needs relatively huge amount of cost to construct and operate and maintain. Thus we must be checked with economical adequacy of the the proposed coastal vessel traffic services by comparing the cost of the construction, operation and maintenance with the expected benefit made by the expected decrease in marine casualties. In previous paper, a proper cost-benefit analysis model for the Korean practice will be suggested. In this Paper, the proposed the cost-benefit analysis model of coastal vessel traffic services was applied to the Koje coastal waters 20mi1es from the top of Maemul-Do and Yokchi-Do. As the result, we confirmed the propriety of the cost-benefit analysis with the application of the proposed model to Koje waters. Also, it is verified that the introduction of coastal vessel traffic services, as proposed, is adequate and economical. The cost-benefit analysis model proposed in this study could be used to investigate the economic Propriety of new aids to navigation and traffic safety facilities in the future.

The purpose of this study is to investigate the fishery perception and recreation fishing demand level of coastal waters ranch with the case in Tongyeong city's Bijin-do Yongcho-do, Juk-do. The study conducts a survey of 27 fishermen and 113 recreation fishing tourists from September 26 to November 21, 2016. The major results of this study are as follows. First, the survey of fishery perception level suggests that the increase of fishery resources by Tongyeong-si coastal waters ranch project contributes to the rising income of fishermen, decreased fishing cost, and increased the number of tourists. Second, the survey of recreation fishing tourists's demand level suggests that a beautiful view, fish populations, kindness of residents, fishing point information, charter information, and the convenience of transportation are highly praised and highly regarded. However, links to nearby tourism, lodging facilities, and food information that can increase the income of fishermen is poorly praised. Therefore, this study suggests that a careful marine policy with fishery resource creation should be followed for marine fishing village tourism consumer's benefits in order to increase fishing village's income.

Salinization is an important environmental problem encountered in coastal aquifers. In order to evaluate the salinization problem in the western coastal area of Korea, we have performed a regional hydrochemical study on shallow well groundwaters (N=229) collected within 10 km away from the coastline. The concentrations of analyzed solutes are very wide in range, suggesting that the hydrochemistry is controlled by several processes such as water-rock interaction, seawater mixing, and anthropogenic contamination. Based on the graphical interpretation of cumulative frequency curves for some hydrochemical parameters (esp., $Cl^{-}$ and ${NO_3}^-$), the collected water samples were grouped into two major populations (1) a background population whose chemistry is predominantly affected by water-rock interaction, and (2) an anomalous population which records the potential influences by either seawater mixing or anthropogenic pollution. The threshold values obtained are 34.7 mg/l for $Cl^{-}$ and 37.2 mg/l for ${NO_3}^-$, Using these two constituents, groundwaters were further grouped into four water types as follows (the numbers in parenthesis indicate the percentage of each type water) : (1) type 1 waters (38%) that are relatively poor in $Cl^{-}$ and ${NO_3}^-$, which may represent their relatively little contamination due to seawater mixing and anthropogenic pollution; (2) type 2 waters (21%) which are enriched in $Cl^{-}$, Indicating the considerable influence by seawater mixing; (3) ${NO_3}^-$-rich, type 3 waters (11%) which record significant anthropogenic pollution; and (4) type 4 waters (30%) enriched in both $Cl^{-}$ and ${NO_3}^-$, reflecting the effects of both seawater mixing and anthropogenic contamination. The results of the water type classification correspond well with the grouping on a Piper's diagram. On a Br x $10^4$versus Cl molar ratio diagram, most of type 2 waters are also plotted along or near the seawater mixing line. The discriminant analysis of hydrochemical data also shows that the classification of waters into four types are so realistic to adequately reflect the major process(es) proposed for the hydrochemical evolution of each water type. As a tool for evaluating the degree of seawater mixing, we propose a parameter called 'Seawater Mixing Index (S.M.I.)’ which is based on the concentrations of Na, Mg, Cl, and $SO_4$. All the type 1 and 3 waters have the S.M.I. values smaller than one, while type 2 and type 4 waters mostly have the values greater than 1. In the western coastal area of Korea, more than 21% of shallow groundwaters appear to be more or less affected by salinization process.

With extension of national jurisdiction over coastal living resources, new dimensions and objectives should be added to international cooperation in distant-water fisheries concepts. For distant-water fishing nations, Korea, joint exploitation of these resources is today considered not only as a way of producing additional income opportunities, but first of all as at least a partial solution to neutralization of harvesting limitations imposed on them in traditionally exploited fishing grounds.This paper explores the development of Korean distant-water fisheries agreements and reviews the various types of agreements currently in place and discusses the future of Korean distant-water fisheries agreements with third countries. The relationship between coastal States and fishing fleets from non-adjacent countries has been transformed since the 1980s. This was primarily a result of the declaration of Exclusive Economic Zones(EEZs) by many coastal states in the years leading up to the close of the negotiations of the UNCLOS in 1982. Significantly, by recognizing the right of coastal states to determine how their waters were to be exploited, UNCLOS provided a legal basis and economic motivation for the negotiation of access agreements between coastal states and distant-water fishing nations, KoreaThere is a real danger that Korean distant-water fisheries agreements could and do result in the adverse environmental impacts experienced in Korean coastal waters being transferred to third country water and consequently creating socio-economic problems for these third countries. Korean distant-water fisheries agreements with third countries have the potential to be a force for good if they are well managed and if the principals that will be applied within Korean coastal waters, through the reform of the distant-water fisheries policy, are applied equally upon third country waters.

A total of 19 species of three genera Dinophysis, Histioneis, and Parahistioneis of the family Dinophysaceae are reported here from samples obtained using a 20-µm mesh net from June 2006 to December 2014 around Jeju Island including the East China Sea, and 16 of these species are new to Korean waters. A checklist of the three genera of dinoflagellates reported from coastal and oceanic Korean waters is presented. Short descriptions and synonyms are given for each species. The dinoflagellates of the family Dinophysaceae belong to mostly marine species, and include many tropical and/or subtropical species. Recently, the composition of dinoflagellate species has changed around Jeju Island as well as in Korean waters due to global warming and climate change. Tropical and subtropical dinoflagellates occur frequently in the coastal waters of Jeju Island, which reflects the ecosystem shift around the sea adjacent to Jeju Island from a temperate to a subtropical / tropical region.

Bottlenose dolphins (Tursiops sp.) commonly inhabit Korean waters, including the coastal waters of Jeju Island. However, their taxonomic position was unclear because of the validity of this genus. The genus Tursiops has recently been determined to comprise two species: the common bottlenose dolphin (Tursiops truncatus) and the Indo-Pacific bottlenose dolphin (Tursiops aduncus). To confirm the taxonomic position of bottlenose dolphins frequenting the coastal waters of Jeju Island, the external morphology and osteology of specimens from Jeju Island were examined. Photographs of free-swimming individuals were also used for determining external morphological characters. The cranial and meristic measurements fell within the ranges of T. aduncus. Osteological ratios were also consistent with those of T. aduncus. The presence of a prominent ventral spot was observed among some individuals. As a result, the dolphins mainly distributed in the coastal waters of Jeju Island were identified as Indo-Pacific bottlenose dolphins (T. aduncus) in terms of their cranial characters and ventral spotting. We propose a new Korean name, 'Nambang-keun-dol-go-rae'.

Quantification of sediment losses into the ambient waters associated with various works of coastal developments is highly required for predicting their possible detrimental impacts on the aquatic environments. Although there have been some studies especially related to dredging (e.g., Nakai, 1978; Kirby and Land, 1991; Collins, 1995; Pennekamp et al., 1996; Lorenz, 1999; Jin et al.,2003), none can be regarded as a general guidance up to date, which results from the facts that the amount of sediments released into the ambient waters is influenced by several site/case-specific conditions, and that the existing studies have been carried out using different methods.

2008년 한반도 남해동부해역에서 Cochlodinium polykrikoides 적조의 발생, 진행 및 소멸현상을 식물플랑크톤 종조성, 물리 화학적 환경요소와 기상자료를 이용하여 분석하였다. 2008년 C. polykrikoides 적조는 7월말에 조기 발생하여 저밀도로 장기간 연안해역에 집중되어 발생하였다. 7월 초부터 동해남부해역에서 발생한 냉수대의 영향으로 외해로부터 C. polykrikoides 가입이 어려웠으며, 연안 저층의 포자(cyst) 발아에 의한 적조발생 이후 약한 바람 및 가뭄으로 인한 낮은 영양염 농도로 적조가 확산 성장하지 못하고 연안해역에 제한되어 발생한 것으로 판단된다.
