We investigated the characteristics of the marine environment and phytoplankton community of surface in the adjoining sea of Yangtze river of the East China Sea in June 2005. According to the analysis of a T-S diagram, three characteristic of water masses were identified. We classified them into the mixed water mass by the Chinese continental coastal waters and Taiwan/Tsushima warm current, Chinese continental coastal waters and Taiwan/Tsushima warm current. The first water mass was characterized by high water temperature, low salinity, low density and very high Chl-a concentration. The second one was characterized by high water temperature, low salinity, low density and high Chl-a concentration and the last one was characterized by low water temperature, high salinity, high density and low Chl-a concentration. The phytoplankton community identified a total of 95 species belonging to 43 genera. The dominant species was 3 species, that is, mainly centric diatom, Skeletonema costatum in the Chinese continental coastal waters. The others one, one dinoflagellates, Prororcentrum donghaiense and one silicoflagellates, Dictyocha speculum var. otonaria in warm current regions. Standing crops of phytoplankton and Chl-a concentration were very high with ranged from 5.9 x 103 cells/L to 1.1 x 106 cells/L, and 2.90 ㎍/L to 26.40 ㎍/L, respectively. Phytoplankton productivity in the East China Sea was controlled by the discharge of Yangtze river waters which include a high concentrations of nutrients.

Distribution characteristics of two dominant paracalanids of the family Paracalanidae on temperature and salinity were studied in the brackish and coastal waters from the West and South coasts of Korea. Bestiolina coreana mainly occurs in a range of 29.8~31.3 psu salinity and temperature of more than about 20℃, while Paracalanus parvus s. l. mainly occurs in a range 17~20℃ temperature and more than 30 psu salinity. The fact clearly indicates that temperature and salinity was a major factors in spatio-temporal distribution between these two paracalanids.

We were carried out on the thermohaline structure and phytoplankton biomass, such as chlorophyll a in the East China Sea during early summer in 2001. As a results of water mass on T-S diagram, three characteristic water mass were identified. We are divide them into coastal water mass, cold water mass and oceanic water mass. The former are characterized by high temperature, low salinity and high Chl-a concentration originated China territory, the secondary are characterized by low temperature, high density and high Chl- a concentration originated bottom cold water of Yellow Sea, and the latter are high temperature, high salinity and low Chl-a concentration originated from Tsushima warm current, between them internal discontinuous layer was formed at the intermediate depth (about 20 ~30m and 45m layer). Phytoplankton biomass, such as chlorophyll a concentration in the East China Sea were controlled by the coastal waters of Chinese Continent.

청계만에는 3개의 방조제(창포, 복길, 구일)가 위치하고 있고 이로부터 유입되는 담수로 인한 환경의 변화가 예상된다. 이를 조사하기 위해 2006년 11월(가을), 2007년 2월(겨울), 5월(봄), 8월(여름)에 각 방조제 앞에서 3개 정점을 선정하였다. 각 방조제 정점에서 대발생은 갈수기인 2007년 2월에 대형식물플랑크톤에 의해 발생하였고 풍수기에는 중 형식물플랑크톤이 우점하는 분포를 나타냈다. 각 방조제 정점에서 풍수기에는 담수의 유입으로 인하여 염분과 투명도는 낮고 암모늄과 인산염은 갈수기인 2007년 2월보다 높게 나타났지만 식물플랑크톤 생체량은 낮게 나타났는데 이는 담수의 유입으로 인한 높은 탁도나 염분의 급격한 감소가 영양염류보다 더 영향을 미치는 것으로 사료된다. 즉 본 조사해역에서 갈수기인 2007년 2월에는 식물플랑크톤의 성장에 영양염류가 영향을 미치지만 풍수기에는 높은 탁도나 급격한 염분변화가 영양염류보다 더 큰 영향을 미치는 것으로 판단된다. Three embankments are located in the Chunggye Bay, each named as Changpo, Bokkil and Kuil and environmental changes are expected due to freshwater input. To investigate this phenomenon, three sample sites in front of each embankment gate were selected in Nov. 2006(autumn), Feb. 2007(winter), May. 2007(spring) and Aug. 2007(summer). At every point of embankment spot, large cells(micro-size, >$20\;{\mu}m$) of phytoplankton were turned out to be a major cause of algal bloom in Feb. 2007 and nano-size($2-20\;{\mu}m$) phytoplankton became dominant during rainy season. In rainy season, each point of embankment showed low salinity and transparency with higher ammonium and phosphorus concentrations than dry season. However, the number of phytoplankton has decreased and it is expected that freshwater influx has more influence on high turbidity and radical decrease of salinity than nutrient. According to the results of this study, therefore, nutrient could have more influence on growth of phytoplankton in dry season, but high turbidity and radical changes of salinity have more influence in rainy season.

We carried out a study on the distribution of phytoplankton community, such as species composition, dominant species, standing crops and chlorophyll a in the Sudo Strait where located the southern parts of West Sea of Korea(Yellow Sea) in spring 2005. The phytoplankton community in the surface waters was a total of 64 species belonging to 38 genera. Standing crops of phytoplankton fluctuated between 14.0 x 103 cells/L and 48.5 x 103 cells/L. Dominant species were one species of centric diatom, Paralia sulcata with dominance 77.7%. Chlorophyll a concentration fluctuated between 1.95 ㎍/L and 5.17 ㎍/L in neap tide (3.58 ± 0.87㎍/L, Mean ±SD), 1.61 ㎍/L and 4.22 ㎍/L in spring tide (3.18 ± 0.60 ㎍/L). The distribution of phytoplankton community and biomass in the Sudo Strait of southern part of West Sea of Korea was controlled by the high concentration of seston weight and tidal currents.

본 논문은 국립수산과학원 “신자산어보 발간을 위한 흑산도 연안생태계 조사 (RP-2013-ME-070)” 연구의 일환으로 수행되었습니다. To understand the seasonal changes in the zooplankton community, we investigated their occurrence patterns and environmental factors during four seasons at 9 stations along the coast of Geumo Archipelago, Yeosu. A total of 44 taxa were sampled, with an abundance ranging from 15~28,183 inds. m- 3, among which Noctiluca scintillans predominented. Noctiluca scintillans, Paracalaus parvus s. l., Acartia (Acartiura) omorii, Oithona spp., Aidanosagitta crassa, dedapods larvae, copepods nauplii, and copepodites were the most abundant taxa detected. Species diversity of zooplankton was high in autumn and winter, but it was relatively low in summer and spring. Non-metric multidimensional scaling (nMDS) revealed significant differences in the structures of the zooplankton community among the seasons. Our results showed that the seasonal variation in zooplankton community along the coast of Guemo Archipelago, Yeosu were attributable to seasonal changes in temperature, salinity, and Chl. a concentration. Additionally, this particularly study area might have been specifically influenced by occurs of the neritic species.
