During the traditional periods when there were exchanges among Korea, China and Japan based on ocean currents or seasonal winds, the southwestern coastal areas including Yeosu held an important position since the route would not have been complete without them. Armed with its advantages including the marine environment, the Yeosu area in the southwestern coast on the Korean Peninsula engage in active maritime exchanges and activities as a base along the sea route since the Neolithic or Bronze Age. It was the same later when Baekje and Gaya had exchanges with China and Japan, when Unified Silla had exchanges with China, and when Goryeo had exchanges with China and Japan. In Joseon, the Yeosu area gained fame as a marine defense base. In short, the Yeosu area in the southwestern coast on the Korean Peninsula during the traditional periods not only engage in active maritime exchanges and activities, but also serve as an important base that could not be left out in the maritime history of East Asia.

우리 나라 남해 서부 연안에서 1996년 4월부터 1997년 3월까지 월 1회 어류를 조사하여 19목 82과 149속 190종을 채집하였다. 그 가운데 농어목은 94종이 출현하여 전체 출현종의 49%를 차지하였다. 채집된 어류중 두줄망둑 Tridentiger trigonocephalus, 실양태 Repomucenus valenciennei 및 풀반댕이 Thryssa adelae가 가장 우세하게 출현하였다. 또한 황해고유종인 왜도라치 Chirolophis wui, 흰베도라치 Pholis faugi, 참돛양태 Repomucenus koreanus, 비늘흰발망둑 Acanthogobious luridus 등이 출현하여 이 지역은 황해의 영향권에 있음을 알 수 있었다.

Twelve Italian ryegrass (Lolium mult~flomm L.) cultivars have recommended as the government recommended forage cultivars since 1984, however, the forage performance and quality have been mostly tested at two locations, such as Suweon and Sunghwan in the Middle Northwestern and Middle Southwestern Coast Regions, respectively. Therefore, the objective of this experiment was to retest the forage performance and quality of already recommended twelve government Italian ryegrass cultivars at five scattered locations, such as Icheon, Suweon, Sunghwan, Keon- and Kwangju from 1992 to 1995 with the intention of improving recommendations to dairy farmers. Cultivars with more dry matter yield than the control 'Tetrone' were 'Tosca' , 'Bartissimo' , 'Florida 80' and 'Gordo' in the Middle Northwestern Coast Region ; 'Tosca' , 'Florida 80' , 'Bartissimo' , 'Wencke' and 'Gordo' in the Middle Southwestern Coast Region ; 'Tosca' , 'Florida 80' , 'Sikem' , 'Bartissimo' , 'Wencke' and 'Gordo' in the Keongbuk Inland Region; 'Florida 80', 'Tosca' , 'Barmultra' and 'Bartissimo' in the Southern Inland Region and 'Florida 80' , 'Gordo' , 'Sikem' , 'Bartissimo' and 'Tosca' in the Southern Coast Region. At all the locations in 1992-95, 'Florida 80' produced the highest forage yield and showed earliness, but this cultivar was less cold tolerant in the Middle Northwestern and Middle Southwestern Coast Regions and grew tall which made it vulnerable to lodging in all the exprimental regions except the Southern Coast. Differences among the ryegrass cultivars for the three year mean ADF and NDF were small and inconsistent.

Potential tsunamis which may occur near Ryukyu Islands were simulated. Propagation characteristics of the potential tsunamis over the southwestern sea and the influence of tsunamis on the southwestern coast of Korean Peninsula were analyzed. The shallow water area in the east sea of China and the deep water Okinawa Trough play an important role in wave transformation and propagation of the potential tsunamis. The propagation characteristics of the potential tsunamis generated near Ryukyu Islands can be described as in followings : In the first stage after generation, the tsunamis propagate with high speed both northeastward and southwestward along the Okinawa Trough. As a result the waves are elongated and the tsunami height is significantly reduced. The elongated crest of tsunamis spans the whole distance of the Okinawa Trough and lines up toward the edge of the continental shelf of East China Sea. Then, the tsunamis are propagating towards the southeast coast of China. Thus, the influence of tsunamis on the Korean coasts becomes weak.

본 연구는 1997년 3월부터 1998년 10월에 걸쳐 이루어졌으며, 한반도 서남해 도서의 소나무림을 대상으로 식물사회학적인 방법에 의해 군락의 유형을 분류하였다. 26개의 방형구를 선정하여 조사한 결과 본 조사 지역의 소나무림은 자금우-소나무군락과 방아풀-소나무군락으로 분류되었고, 각각의 군락은 털머위하위군락, 졸참나무하위군락 및 전형하위군락과 노간주나무하위군락, 윤노리나무하위군락 및 전형하위군락으로 구분되었다.

2007년 12월 7일 발생한 허베이스피리트호 원유유출 사고로 약 12,547 kL의 기름이 해상으로 유출되어 서해안의 해안선이 광범위하게 기름으로 뒤덮이는 결과가 초래되었다. 사고발생 며칠 후부터 타르볼이 서남해안에서 관측되었으며, 이에 대한 방제를 위해 해양경찰(KCG)은 해상에서는 뜰채 및 그물끌기 방법을 이용하였고, 해안에서는 그물치기, 주워내기, 쓸어 담기 등 3가지 방제방법을 이용하였다. 그물막 치기 방법은 해안이 타르볼로 오염되는 것을 예방하는데 효과적이었으며, 사고당시의 계절이 겨울이었던 점은 타르볼이 쉽게 굳어 자원봉사자나 주민들이 주워 내거나 쓸어 담는데 큰 이점이 될 수 있었다.

With the results of observations in 2013 and 2014 including ocean buoys, in-situ investigations and wind data, we examined the spatio-temporal variation of cold water masses along the eastern coast of Korea. Usually, a cold water mass first appears along the northern part of the eastern coast from May to July, and then along the southern part of the eastern coast from late June to mid-August. Cold water masses appear 3~5 times a year and remain for 5~20 days in the southwestern part of the East Sea. A distinctive cold water mass appeared usually in mid-July in this area, the surface temperature of which was below $10^{\circ}C$ in some cases. During the appearance of a cold water mass in the southwestern part of the East Sea, the horizontal temperature gradient was large at the surface and a significant low water temperature below $8^{\circ}C$ appeared at the bottom level. This appearance of cold water masses clearly corresponded to southwesterly winds, which generated coastal upwelling.

We examined the community structure of fish off the coast of Jindo Island in response to a cold water appearance in the southwestern sea of Korea each August between 2013–2015. Using a gape net with wings, we collected 31 taxa during the study period, wherein the most dominant species was Engraulis japonicus. Collichthys lucidus and Neosalanx andersoni, which are mainly distributed in the western sea of Korea, increased in abundance and were dominant in August 2013, possibly due to the apparent intrusion of cold water (< 19°C) from offshore into the coastal waters of Jindo Island. Meanwhile, Scomberomorus niphonius and Sardinella zunasi, which are known as warmwater migratory species, increased in abundance and were dominant in August 2015, likely influenced by the warmer water (> 20°C) at the coast, which resulted in a noticeable lessening of the cold water in the study area. However, no significant differences were observed in fish community structure in the month of August between 2013–1015. This implies that the small-scale spatial and temporal variations in the cold water had limited effects on the fish community structure, even though the abundances of several dominant species varied in the coastal waters.

Heavy metal concentration of Fe, Zn, Cu, Cd and Pb were analysed from seaweeds (Ulva pertusa, Sargassum thunbergii, Caulacanthus okamurae), sediments and seawater at the two experimental sites of Daebul and Sabjin industrial complex in Mokpo coastal area with a control site (Heugsando). Highest values of heavy metals were found at two experimental sites influencing by various pollution sources such as industrial drains, sewage and harbours. In contrast, the lowest concentrations was observed at the control site without any pollution source. The concentration levels of accumulated heavy metals were in the following order: seaweeds > sediments > seawater. Similar spatial distribution patterns were observed at the seaweeds, sediments and seawater for the highest mean values of the different heavy metals. This result show that seaweeds could be used as a biomonitors of heavy metals at coastal region.
