  • Gammaropsis utinomii (Nagata, 1961), an incompletely known species of gammaridean amphipod, is redescribed in detail based on the specimens from the southern coast of Korea. The expanded basis of pereopod 7 of this species allows it to be distinguished from its congeners.

  • The hypothetical earthquake located on the fault zone along the western coast of Japan, where sufficient time has elapsed since the last earthquake or an earthquake has not occurred yet, is known to possess significant potential energy. The possibility of earthquake activities occurring here in the future is high. It is expected that the resulting tsunamis will cause great damage to the East Sea coast of Korea and affect parts of the southern coast as well. In this study, tsunami that may be caused by a virtual earthquake that is expected in the hypothetical earthquake, along the western coast of Japan, will be estimated using numerical simulation. From this, the effect of the tsunami originating from the hypothetical earthquake on the southeastern coast of Korea will be evaluated by examining the water level rise due to the maximum water level rise and changing time, for each point along the southeastern coast. It will be possible to use the virtual results obtained like this as important basic materials in future disaster prevention plans and designs, for determining the direction of coastal development, for arranging seashore and harbor structures and to carry out wave resistant design for the southeastern coast of Korea.

  • Storm surges caused by typhoon Billie, 28 Aug. ∼ 2 Sep. 1970, on the west and south coasts of Korea are studied with the tidal data. Tracks and frequencies of the typhoons which affected the Korean peninsula and the yearly maximum tidal deviation at tide stations for the past twelve years are also reviewed. It is assumed that most of the typhoons affecting the Korea peninsula cause variations of sea level along almost all of the coast of Korea. Maximum storm surges at each tide station on the south coast appeared to be caused by typhoons during the summer, and by the north westerly monsoon and extraordinary cyclones on the west coast during spring and winter. In the coastal waters of the west coast where depths are shallower and the bottom configuration is flat, sea level variation is mostly caused by atmospheric pressure and wind effect. When a typhoon travels as in case of typhoon Billie, sea level ascends generally on the south coast and it descends on the west coast before the typhoon approaches near to the coasts. Considering the large tidal range on the western and southern coasts, it is assumed that the extraordinary destructive surges can be occurred when the tide is high water. Reviewing the monthly mean sea level variations on the each coast, hazards to be caused by storm surges can more fluently occur during the summer.

  • The flora of Kayasan National Park which was located at the southern part of Korea was investigated between April 30-31. August 10-14, and October 9-10. 1989. The number of vascular plants investigated in the present study was summarized as 96 families, 292 genera, 465 species, 72 varities, and 4 forms. The middle and Southern types of distribution pattern were the largest as of 9 families and 12 species. It was very interesting that the warm temperate types of species, as well as southern coast and island types of plant were introduced to this region.

  • Four Tertiary basins are distributed on the eastern coast of the southern Korean Peninsula, that is, Bugpyeong, Yeonghae, Pohang and Yangnam basins from north to south. The Yangnam and Pohang basins are the largest ones and have been well studied on their stratigraphies, paleoenvironments and geologic ages, and their tectonic history is representative on the tectogenesis of the Tertiary basins of the southern Korean Peninsula. The geologic events occurred in the Yangnam and Pohang basins from the Early-Middle Eocene through the Middle Miocene suggest that the Yangnam and Pohang basins resulted from the volcanism and rifting caused by the uprising magma, that is, by the diapiric tectogenesis.

  • In this paper South Africa is divided into strong wind climate zones, which indicate the main sources of annual maximum wind gusts. By the analysis of wind gust data of 94 weather stations, which had continuous climate time series of 10 years or longer, six sources, or strong-wind producing mechanisms, could be identified and zoned accordingly. The two primary causes of strong wind gusts are thunderstorm activity and extratropical low pressure systems, which are associated with the passage of cold fronts over the southern African subcontinent. Over the eastern and central interior of South Africa annual maximum wind gusts are usually caused by thunderstorm gust fronts during summer, while in the western and southern interior extratropical cyclones play the most dominant role. Along the coast and adjacent interior annual extreme gusts are usually caused by extratropical cyclones. Four secondary sources of strong winds are the ridging of the quasi-stationary Atlantic and Indian Ocean high pressure systems over the subcontinent, surface troughs to the west in the interior with strong ridging from the east, convergence from the interior towards isolated low pressure systems or deep coastal low pressure systems, and deep surface troughs on the West Coast.

  • We investigated the variation of morphological features, density, biomass and characteristics of reproductive shoot on Zostera marina. This species was monthly monitored and collected during a year in Tongyeong (from January 2016 to December 2016). Morphological features, biomass and density showed significantly seasonal variation (p<0.001). Dimensions of Z. marina were highest in spring and early summer but lowest in winter. Biomass and leaf density of Z. marina showed highest value in May (4,700.5 g w·wt m-2) and June (858.0 leaves m-2) respectively and lowest value in November (515.9 g w·wt m-2 and 312.0 leaves m-2). Reproductive shoot was monitored from April (13℃) to June (21℃) and grew up to ca. 200 cm. Spathe length, spadix weight, numbers and weight of fruit showed significantly different on monthly. None mature flowers were monitored in April but matured flowers, fruits were founded in May and seed releasing were occurred in June.

  • this study was performed for the purpose of surveying the distribution and characteristics of the Vibrio species in the diseased farm flounders (Paralichthys olivaceus) during the winter season in Korea. Samples were collected along the southern coast in the Sinam, Keoje Island, and Teosu areas from November '90 to Feburary '91. Nine species of Vibrio were identified as V. tubiashii (85 strains), V. damsela (78 strains), V. anguillarum (21 strains), V. compbelli (9 strains), V. fluvialis (9 strain), V. costicola (1 strain), V. alginolyticus (1 strain), V. gazogenes (1 strain), V. marinus (1 strain), and unidentified 3 groups of bacteria (154 strains) which may have related with V. tubiashii were isolated. Eleven kinds of discs (BBL Co.) were used for antibiotic susceptibility test and 116 strains were selected for the experiment. Most bacteria were powerfully inhibited their growth by 4 antibiotics such as cephalothin, chloramphenicol, colistin, and tetracycline, but they were poorly inhibited by 4 antibiotics such as carbenicillin, kanamycin, penicillin G, and streptomycin.
