Phytoplankton plays an important part as indicator and primary producer in marine ecosystem. Therefore, phytoplankton community appeared variously according to marine environment, so the data of nutrients, chlorophyll a, temperature, salinity, and DO were analyzed in seagrass bed of Yeoja Bay. Consequently, the phytoplankton community structures were associated with investigation time and place, and seen difference according to the existence and nonexistence of seagrass bed.

The purpose of this study is to process a seaweed resources that is easy to find in Korea and has outstanding phlogistone and high yield seaweed vinegar solution through mass-production and facility development for utilization. The compound uses wasted seaweeds, such as brown seaweed, kelp, seaweed fusiform, and laver, and carbonizes them in high temperature by drying in poly step trap to extract them. In also involves the development of a process that separates and refines the extracts to create a high value-added anti-bacterial bio solution that can replace chemicals in agriculture and industries and even chemical food additives. so, studied separation and refining of seaweed extracts to analyze the compounds. and processed and compared to seaweed vinegar extracts to prove superiority.

해양 규조류는 일차생산자로서의 중요성 이외에도 수질 오염의 정도를 파악하거나 생리학 내지는 내성 연구나 규산 대사에 관한 연구에도 가장 많이 사용되어지고 있는 주요 식물플랑크톤이다 (Werner,1977;Wear, 1999). 이 중 특정 기질에 부착하여 서식하는 규조류를 부착규조라고 하며, 해초와 같은 식물, 저질, 동물의 표면, 이 외의 여러 부착기질에 점액질을 이용하여 부착 서식한다. (중략)

Despite the ecological importance of seagrass beds, their distributional information in Korean coastal waters is insufficient. Therefore, we used hydroacoustic system to collect accurate bathymetry and classification of seagrass, and Kompsat-2 (4 m spatial resolution) image for detection of seagrass beds at Deukryang Bay, Korea. The accuracy of Kompsat-2 image classification was evaluated using hydracoustic survey result using error matrix and Kappa value. The total area of seagrass beds from satellite image classification was underestimated compared to the hydroacoustic survey, estimated 3.9 and $4.5km^2$ from satellite image and hydroacoustic data, respectively. Nonetheless, the accuracy of Kompsat-2 image classification over hydroacoustic-based method showing 90% (Kappa=0.85) for the three class maps (seagrass, unvegetated seawater and aquaculture). The agreement between the satellite image classification and the hydroacoustic result was 77.1% (the seagrass presence/absence map). From our result of satellite image classification, Kompsat-2 image is suitable for mapping seagrass beds with high accuracy and non-destructive method. For more accurate information, more researches with a variety of high-resolution satellite image will be preceded.

The study on the classification of the Chindo Islands ascidians was conducted by collecting the specimens from five localities in July and November, 1994 and the previous records. The ascidians were classified into 7 families, 11 genera and 16 species. They are all known species in Korean waters. Among them nine species were found to be new to the Chindo Is. From the standpoint of water forms, the composition of the ascidians from Chindo Is. is made up of three elements, viz., temperate (8species, 50%), temperature-tropical (7 species, 44%) and tropical (1 species, 6%) . A boreal water species and boreal-temperature species were not found . It may be attributable to the fact that the water of this area is warm because of Kuroshio Water Current.

In order to carry out a systematic study of ascidians in Cheju Island, the authors identified and classified specimens collected from 11 sites around Cheju Island from December 1 1969 to January 1989. Using the information gathered from this study as well as previous s studies, the authors prepared a detailed list of the ascidians of Cheju Island. A As a result of this study, the ascidians of Cheju Island are 50 species in 10 families. Among them, 3 species (Dideηmum apersum, Didemnum translucidum, Botrylloides perspicuum) had not previously been known to exist in Korean waters. Description and drawings of these three species are presented in this report. It was also discovered that ten of the fifty species are found only in the Cheju Island area. The fifty species recorded in the Cheju Island area account for 68% of the seventy three species recorded from all Korea. Classifying them by t the temperature of the water where they are found, the authors found the following: one cold water species (2% of the total), seven cold-temperate water species (14%), thirty eight warm-temperate water species (76%) and four tropical water species (8%)

본 연구에서는 해양의 기초 생산자인 잘피 (Zostera marina)의 후방산란 특성을 일주기 동안 관측 하였다. 해상 실험은 2004년 2월 $25\~29$일 기간 중 남해 동대만에서 실시 하였다. 그랩(Grab)을 이용하여 해초지의 입도를 분석 하였으며 주파수별 산란 특성을 고려하기 위해서 17, 30, 50, 80, 100, 그리고 120kHz 음원을 해초지에 수직 지향하여 주, 야간 잘피의 후방 산란을 측정하였다. 실험 환경 분석을 위해 파고와 조석 및 잘피의 생체량(biomass)측정을 실시 하였다. 광합성 시 해초지에서 발생되는 산소 공기는 해수에 의해 용존 되거나 산소 가스 형태로 존재하게 된다. 이들 공기 방울에 의해서 형성되는 공기 방울 층은 음 세기의 감쇠를 야기 시킨다. 실험 결과 주, 야간 동안 음의 산란 강도 변화를 확인 하였다.

한반도에 서식하는 해초(Seagrass) 중 거머리말속(Zostera, Zosteraceae)은 거머말(Zostera marina), 애기거머리말(Z. japonica), 왕거머리말(Z. asiatica), 수거머리(Z. caulescens), 포기거머리말(Z. caespitosa) 5종이 기재되었다 (Miki, 1932). 이 해들은 연안의 사질 또는 사니질에 서식하며 생태계에 중요한 역할을 담당하고 있다. 그러나 연안의 매립과 개발로 인해 이들 해초지의 감소와 연안생태계의 붕괴가 진행되고 있으나 해초에 대한, 특히 Zostera속에 대한 연구는 미진하다.(중략)
