  • With the economic development in China, the utilization of silty and muddy coasts including the construction of deepwater harbors and channels are being carried out at a fast pace. In these projects, the key technology involved is sediment transport. Due to the complication of sediment problems under the actions of tidal currents and wind waves, physical experiments are necessary In addition to numerical model studies. (omitted)

  • Most soft ground in the southern and western coasts in Korea consists of very compressible alluvial deposits. Four samples in these alluvial deposite were selected to manifest the constitutive relations of consolidation. A series of tests were performed to investigate void ratio -effective stress relationand void ratio-coefficient of permeability relation on soil samples obtained at Haenam. Jindo Mankyung and Janghung permeabilities by CRS thoery were similar to directly measured data but those of indirectly computed by $C\upsilon$ shows difference. Several models about compressibility and permeability were compared with test data.

  • It was studied on the choice of potential area for red tide occurrence from oceanographic factors. Oceanographic factors of favorable marine environmental conditions for the red tide formation included warm water temperature, low salinity, high suspended solid, low phosphorus, low nitrogen. It was founded the potential areas for red tide occurrence in August 2000 by GIS conception: Yeosu~Dolsan coast, Gamak bay, Namhae coast, Marado coast, Goheung coast, Deukryang bay, respectively.

  • Some scyphomedusae were collected from the coasts of Ilgwang, Jeju Harbour, Yeosu, Yokjido Is. and Munyeodo Is. in Korea from May to Nov. 2004. They were indentified into Pelagia noctiluca Forskal, 1775 and Cyanea nozakii Kishinouye, 1891 of the order Semaeostomeae and Nemopilema nomurai Kishinouye, 1922 of the order Rhizostomeae in the class Scyphozoa. They are new to the Korean fauna.

  • The migration status of waterbirds inhabiting the 10 coastal wetlands in the south and west coasts (Jangbongdo, Muuido, Daecheoncheon estuary, Seocheon tidal flat, Yubudo, Gomso bay, Hauido, Jeungdo, Doam bay, Gangjin bay) was examined from May 2008 to March 2013. For the most dominant taxonomical group, shorebirds accounted for 37.5% of the number of species and 67.1% of the total population, followed in the order of dabbling ducks, herons, and seagulls. The dominate species were Calidris alpina, Larus crassirostris, Limosa lapponica, Charadrius alexandrinus, and Calidris tenuirostris. Shorebirds were observed most at Seocheon Tidal Flats and Yubudo Island, and dabbling ducks were found most in Doam Bay. Diving ducks were observed most at Gangjin Bay and seagulls were seen most frequently at Seocheon Tidal Flats. The ten coastal wetlands of the western and southern coasts were divided into three groups according to the similarity index of waterbirds (Ro). Group 1 was the area where dabbling ducks and diving ducks were dominant, group 2 was the area where shorebirds were dominant, and group 3 was the area where seagulls were dominant. It was evident that there were differences in species composition depending on the regional environments.

  • Some scyphomedusae were collected from the coasts of Busan (Gijang), Geojedo Island(Jangmok-ri) and Samcheok during the period from June 1989 to May 1999. They were identified into Stenoscyphus inabai of Stauromedusae and Aurelia aurita in Semaeostomeae. They are first recorded in Korea.

  • A total of twenty one species of marine macro-algae were reported from 460 kms long Orissa coast in the east coast of India. Of these 9 species belongs to Chlorophyta, 2 to Phaeophyta and 10 to Rhodophyta. The low species richness compared with southern and western coasts of India was due to lack of rocky and/or coral substratum. Enteromorpha usneoides and Gelidium divaricatum were reported first from India. Enteromorpha linza, E. clathrata, Colpomenia sinuosa, Dictyota dichotoma, Catenella impudica, Compsopogon aeruginosus and Grateloupia lithophila were the new records for Orissa coast.

  • Four species of the genus Atylus belonging to the family Dexaminidae are reported from the eastern and southern coasts of Korea. Three of these species are redescribed as new records of this country: Atylus (Atylus) ekmani (Gurjanova), A. (A.) matsukawaensis Hirayama and Takeuchi and A. (Kamehatylus) japonicus Nagata.

  • In the present paper, seven marine algae collected from the coasts of Korea are described. The two blue-green algae, Coccochloris stagnina Sprengel and Entophysalis conferta (Kuetz.) Drouet and Daily, one brown alga, Ralfsia verrucosa(Aresch.) J. Ag., and the two red algae, Enelittosiphonia hakodatensis (Yendo) Segi and Symphyocladia pennata Okamura, are recorded newly in our country. The other two blue-green algae, Anacystis dimidiata (Kuetz.) Drouet and Daily and Phormidium tenue (Meneghini) Gomont, are recorded for the first time marine water in our country.
