Air pollutants were measured eight times from June 1999 to June 2002 on regular ferries cruising across the Yellow Sea between Incheon in Korea and Qingdao or Tianjin in China. PM$_{10}$ and PM$_{2.5}$ were measured as particulate matters and SO$_2$, CO, and NO$_{x}$ were measured as gaseous pollutants. On each route, sampling was made, starting two hour after departure and ending two hour before arrival. Low concentrations of gaseous pollutants that were not much varied according to sampling period and location revealed that atmosphere over the sea was not directly affected by anthropogenic emissions. However, concentrations of fine particles were generally higher than those measured at Deokjeok Island, 50km west of the western seashore, at similar periods. It was believed that considerable influence of China in the form of secondary pollutants was exerted over the sea.a.a.a.

Yellow croacker, Tseudociaena manchurica Jordan et Thompson in the Yellow Sea and East China Sea are subjected to be caught by trawl nets throughout the year. First indices of population size in every period 8re calculated. Considering present status of the yellow croacker fishery and ecology of the fish, mathematical models must have been established in order to determine catchability coefficient, natural m ortali ty, fishing mortality, recrui ting coefficient of the fish ing ground, and dispersion coefficienl from the fishing ground. The results an, summmarized as follows: Catchabil i ty coefficient $(C) = 2. 2628 {\times} 10^{-5}$ Natural mortality (M)=0.3293 Population for lhe first half season(July 1st to the following January 3lst) Initial population = 14, 621 $/\frac{M}{T}$ Recruitment =45, 597 $/\frac{M}{T}$ Natural mortality = 8, 660 $/\frac{M}{T}$ Final population =42, 970 $/\frac{M}{T}$ Population for the latter 1131f scason(February 1st to June 30th) Initial population = 69, 170 $/\frac{M}{T}$ Dispersion =51, 688 $/\frac{M}{T}$ Natural mortality = 6, 082 $/\frac{M}{T}$ Final population = 1, 802 $/\frac{M}{T}$.

The relationship between the distribution of demersal fishes and that of the water masses was examined by using the catches data and hydrographic data in the Yellow Sea and the East China Sea on May 13-19, 1996 and May 10-17, 1997. During the study period, the dominant fish species were Cleisthenes pinetorum herzinsteini, Lophiomus setigerus and Pseudosciaena polyactis. These three low temperature water species accounted for $21-24\%$ of the total catches. The percentage of the low temperature water species was high in the Yellow Sea and the coastal area on the continental shelf of the East China Sea but was low in the vincinity of Kyushu during the study period. In the East China Sea, the isotherm of $15^{\circ}C$ at 50m, mid layer depth, was located more southeast in 1996 than in 1997. The bottom water temperature was about it lower in 1996 than in 1997. The direction of the detided current on the continental shelf of the East China Sea was southward in 1996 and northward in 1997. Yellow Sea Bottom Cold Water (YSBCW) strongly expanded to south in 1996 when the northward current was weak. But, Tsushima Warm Current (TSWC) strongly intruded into the continental shelf of the East China Sea in 1997. As YSBCW expanded strongly to south in 1996, the percentage of the low temperature water species relative to the total catches was high. But, TSWC strongly intruded and the percentage of low temperature water fishes was low in 1997.

해색 센서인 SeaWIFS의 자료를 이용하여 황사의 광학적 성질과 황사가 해색 원격탐사에 미치는 영향에 대해 연구하였다. 황사가 해색에 미치는 영향을 살펴보기 위해 황사현상이 나타났던 1998년 4월 18일과 맑은 날인 4월 25일의 자료를 선택하였다. NASA 표준 대기 보정 알고리즘은 황사의 영역을 복사휘도가 너무 크거나 또는 구름의 영역으로 간주하여 황사 지역에 대한 해색 정보를 생산하지 않고 있다. 4월 18일 동아시아 해양에 도착한 황사는 에어로졸의 광학적 두께의 관점에서 상대적으로 균질한 두 부류로 구성되어 있음을 보여주었다. 즉, 에어로졸 광학적 두께가 0.8 부근에 최대의값을 갖는 강한 황사와 0.4 부근의 값을 갖는 약한 황사가 존재하였다. 즉 에어로졸 광학적 두께가 0.8 부근에 최대의 값을 갖는 강항 황사와 0.4 부근의 값을 갖는 약한 황사가 존재하였으며, 이 값들은 지상의 관측 결과와 잘 일치하였다. 지상 일기도의 분석과 경로 역추적을 통해 얻은 황사의 이동은 약한 황사 영역이 먼지 폭풍의 가장자리로부터 기원하고 있음을 암시한다. 또한, 황사와 관련된 에어로졸 광학적 두께가 큰 영역은 dir 0.2 정도의 광학적 두께를 갖는 배경 에어로졸과 매우 다름을 알 수 있다. 이러한 에어로졸의 광학적 특성은 대기 보정 변수의 도입과 더불어 황사의 영역을 정량적으로 결정할 수있음을 가능케 하고 있다. 본 논문의 결과는 대기 보정 변수와 광학적 두께의 분산 그래프에 나타나는 특징을 황사 영역을 결정할 수 있음을 보여준다.

Ten-year AVHRR sea surface temperature data obtained in the Yellow Sea are put into EOF analyses. Temperature variation is predominated by the first mode which is associated with the seasonal fluctuation of temperature with annual range decreasing with the bottom depth. Since such a strong annual signal may mask the upwind or downwind flows occurring intermittently during the winter, only the data obtained during this season are put into EOF analyses. Every winter shows similar results. The first mode, explaining more than 90% of total variance, appears to be a part of the seasonal variation of temperature mentioned above. In the second mode, the time coefficient is well correlated with northerly winds to which the responses of the trough and shallow coastal areas are opposite to each other. A simple theoretical consideration suggests the following physical explanation: The northerly wind stress anomaly creates an upwind (downwind) flow over the trough (coastal) areas, which then induces a temperature increase (decrease) by advection of heat, and vice versa for the southerly wind stress anomaly. Hence, this paper provides further evidence of the intermittent upwind or downwind flows occurring in the Yellow Sea every winter.

To gain a greater understanding of the potential for future harmful algal bloom (HAB) outbreaks and to trace the dispersal paths of dinoflagellates, sediment samples were collected from 13 stations in the southeastern Yellow Sea. 23 different types of dinoflagellate resting cysts were identified from the samples. Protoceratium reticulatum (1-391 cells/g dry weight), Gonyaulax scrippsae (0-254 cells/g dry weight), G. spinifera (0-301 cells/g dry weight) and Alexandrium spp. (ellipsoidal type) (0-76 cells/g dry weight) were the dominant species at all surveyed stations. The overall distribution pattern demonstrated that the resting cyst densities were highest in the offshore area and decreased gradually toward the Korean coast. On the other hand, the composition rate of resting cysts of the heterotrophic dinoflagellate species to the total dinoflagellates was higher in the Korean coast region than in the offshore area. We supposed that this distribution pattern of dinoflagellate resting cysts appeared to be influenced by the hydrographic features and environmental conditions of the Yellow Sea.

The chlorophyll-a concentration measured by OCTS could be used for observing the physical phenomena such as eddies, fronts, and up welling in the oceans as well as for studying the ecology of phytoplankton. In this study, biological and physical features in the East Sea/Japan Sea (the East Sea) and the Yellow Sea observed by OCTS are analyzed in comparison with other satellite data. And in situ chlorophyll data were compared with OCTS Level 2 chlorophyll data. There was a striking correspondence between the satellite chlorophyll structure and other satellite data in the East Sea in the spring. Very complicated ring structures in the 557 are reflected in chlorophyll structure. In the Yellow Sea, the surface structure was rather simple. While the discrepancies between in situ and OCTS algorithm version 3 chlorophyll were small in the East Sea, those for the Yellow Sea were rather big. Comparison with CZCS data for similar time of the year (May-June) shows that OCTS chlorophyll is higher in general. Although the error is partly due to the fact that NASDA chlorophyll algorithm is an empirical algorithm for case 1 water, how much of this error is also due to the errors in sensor calibration or in atmospheric correction is not clear.

This thesis is concerned with international fisheries cooperation among Korea, China and Japan in the Yellow sea and the East China sea. For this purpose, considerated international fisheries problems relation with these countries refer to literature. Specially adjusted the focus founding of necessity and methods about international fisheries cooperation among these countries. The conclusion is as followed; At first, these countries necessity required international fisheries cooperation because of following reasons. 1. These countries have legal duties for conservation and utilization of marine living resources according to united nations convention law of the sea. 2. These countries that jointly owned semi-closed sea have legal duties for cooperation in respect of fisheries and environment problems. 3. These countries belongs to a same ecosystem and shared with staddling stocks in the Yellow sea and the East china sea. The Second, these countries certainly required international fisheries cooperation following methods. 1. These countries must establish marine area for joint control of marine living resources. 2. These countries must establish tentatively named "International fisheries cooperation body" for deal with comprehensive problems about fisheries.
