  • 이 연구는 황·동중국해와 동해 울릉분지 사이에 위치한 수로를 대한해협(Korea Strait)으로 명명한 역사적 사실을 바탕으로 향후 국내 연구자들이 활용할 수 있는 일관된 명명법과 지리적 영역을 제시하였다. 국제적으로 대한해협으로 알려진 이 수역은 일상에서 보통 남해로 불리지만, 역사적 근거에 기초하여 대한해협으로 불리는 것이 바람직하다. 이러한 권장안 사용을 뒷받침하기 위해, 먼저 우리나라 주변해역에 대한 고지도, 고해도, IHO 특별간행물(S-23) 등을 분석하여 과거 대한해협의 공간범위를 정의하였고, 대한해협과 대한해협 내 서수도·동수도 지명들의 변천 과정을 조사하였다. 이를 바탕으로 지난 17년(2005-2021년) 간 Ocean Science Journal (OSJ)과 Journal of Oceanography (JO)에 실린 논문들 중 지도에 Korea Strait 또는 관련 지명(South Sea, Korea/Tsushima Straits, Tsushima Strait)을 표기한 논문들을 분석하여 연구자들의 대한해협 지명 표기와 그 공간적 위치에 대한 인식을 조사하였다. OSJ의 경우에 42.9%가 'Korea Strait'를 표기한 반면에 JO의 경우 60.4%가 'Tsushima Strait'를 표기하였다. 하지만, OSJ에는 'Tsushima Strait'를 단독으로 표기한 논문이 한 편도 없었으나, JO에는 7.5%가 'Korea Strait'를 단독으로 표기하였다. 두 국제학술지에서 실린 'Korea Strait' 지명 표기 위치는 크게 5가지 형태로 분류되었다. 즉, 각 논문에서는 대한해협을 광의의 대한해협 영역(Type 1), 울릉분지와 대마도 사이(Type 2), 대한해협 내 서수도(Type 3-1), 대한해협 내 동수도(Type 3-2), 대한해협 내 서·동수도(Type 4)에 표기하고 있었다. 이 중 Type 1이 OSJ의 경우 71.4%를, JO의 경우 60.4%를 차지하여, 광의의 대한해협 영역에 가장 빈번하게 이 해협의 이름을 표기하고 있었다. 끝으로 현재 대한해협을 흐르는 해류의 명칭이 국제적으로 '대한난류'가 아닌 '대마난류' 즉 대한해협 지명에서 비롯하지 않은 명칭이라는 사실에 관해 논의하였다.

  • A steady, strong southward flow was observed in the lower layer beneath the Tsushima Warm Current in the deepest trough of the Korea Strait. Known as the Korea Strait Bottom Cold Water (KSBCW), this bottom current had a mean velocity of 24 cm/s and temperatures below 8–10℃. The direction of the bottom current was highly stable due to the topographic effects of the elongated trough. To determine the path of the southward bottom current, ADCP (Acoustic Doppler Current Profiler) data from 14 stations between 1999 and 2005 were examined. Persistent southward flows with average speeds of 4–10 cm/s were observed at only three places to the north of the strait where the bottom depths were 100–124 m. The collected data suggest a possible course of the southward bottom current along the southeast Korean coast before entering the deep trough of the Strait.

  • A relationship between sea level variations in the Korea Strait (the western and the eastern channels) and the Tokara Strait in the Kuroshio region is examined using daily-mean sea level data from 1966 to 1986. The seasonal variation of the sea level difference (SLD) between Izuhara and Pusan (the western channel) is most periodic: the positive anomalies appear from summer to autumn, and the negative anomalies from winter to spring year to year, whereas SLDs neither between Hakata and Izuhara (the eastern channel) nor between Naze and Nishinoomote (the Tokara Strait) show such a periodic variation. Much similarity has been found between SLDs in the eastern channel and the Tokara Strait, and in particular they were closely correlated in a special event of the Kuroshio region, such as a large meander of the Kuroshio. This paper shows that the periodic seasonal variation of the SLDs in the western channel should be less related to the Kuroshio region. This result also implies that the variation of SLD in the western channel is largely influenced by local factors, such as the bottom cold water in the western channel in summer, rather than from the Kuroshio region.

  • A shallow water numerical model is established to investigate the response of coastal water in the Korea Strait to typhoons that pass nearby the Korea Strait. Atmospheric pressure and wind by Fujita's formula (1952) and Miyazaki et al. (1961), respectively are used in the model. The model results show an agreement fair with the observation partially, but poor with the amplitude of the sea level variation. In particular, the discrepancy is larger in a typhoon passing through right side than that through left side of the Korea Strait. The model showes that the disagreement between the model and the observation can be caused by numerically unrealistic distributions of armospheric pressure and wind around the strait. In the Korea Strait the isostatic effects in the model were underestimated, whereas the wind fields were overestimated.

  • International law provides for fundamental navigational rights called the right of transit passage in international straits as defined by UNCLOS. However, the Australian government published Marine Notice 8/2006 and the associated Part 54 of Australian Marine Orders which requires ships transiting the Torres Strait to engage the services of a pilot and imposes significant penalties for non-compliance on the basis of the IMO MEPC 133(53) which is just a resolution as a recommendation. This paper aims to study legal aspects in UNCLOS on the pilotage in the Torres Strait following the extension of the Great Barrier Reef PSSA neighbouring Australia.

  • The monthly observations of hydrography in the Cheju Strait from September 1995 to June 1998 show that the Cheju Strait is occupied mostly by Tsushima Current Water in winter and coastal waters in summer. In summer, the Yangtze Coastal Water appears in the upper layer and cold water in the lower layer. Especially, the Yellow Sea Bottom Cold Water appears in August 1997, and the clockwise flow of warm water along the northwestern coasts of Cheju Island is disturbed by an eastward expansion of the cold water from the northwest. The cold water expansion seems to be partly associated with strong southeasterly winds. Current measurements in the Cheju Strait suggest that there exists steady eastward barotropic component of about 5 cm/sec, which corresponds to 0.2 Sv barotropic transport in the Cheju Strait. Geostropic transport (baroclinic component) ranges from 0.1 Sv in winter to 0.4 Sv in summer. By adding the barotrophic component of 0.2 Sv, the total transport varies from 0.3 Sv to 0.6 Sv, which is consistent with previous estimations. The transport increase in summer seems to be caused by the expansion of coastal water to the Cheju Strait.

  • Low salinity water was observed during May in the Cheju Strait. Its structure and source were studied by using both the hydrographic data collected not only in the Cheju Strait during 1987-1989 but also in the wider area around Cheju Island extending to the Bank of Changjiang river in 1994 and the current data taken in the Strait during 1987-1989. The water had lower values of temperature, salinity, and density compared with the surrounding water and it was found in the surface layer outside of Tsushima Current Water 10-50 km off Cheju coast. The density of low salinity water was more dependent on salinity than on temperature. The low salinity water flowed into the Strait from the west as a series of intermittent waters whose size was variable in width and in thickness. The low salinity water was originated from the Chanajiang River Diluted Water. In the Cheju Strait, the water showed changes within 3 days on time and 30-50 km on space, and its sudden appearance was marked especially in May. Such strong variability and sudden appearance may be attributed to the beginning stage in May when the fresh water of Changjiang River Diluted Water starts to arrive in the Cheju Strait.

  • A time-series sediment trap was deployed at a depth of 1034 m in the eastern Bransfield Strait from December 25, 1998 to December 24, 1999. Particle fluxes showed large seasonal variation; about 99% of the annual total mass flux (49 g m/sup -2/) was collected during the austral summer and fall (January-March). Settling particles consisted primarily of biogenic silica, organic carbon, calcium carbonate, and lithogenic material. Biogenic silica and lithogenic material predominated settling particles, comprising 36% and 30% of the total mass flux, respectively, followed by organic carbon, 11% and calcium carbonate, merely 0.6%. The annual organic carbon flux was 5.4 g C m/sup -2/ at 1000 m in the eastern Bransfield Strait, which is greater than the central Strait flux. The relatively lower flux of organic carbon in the central Bransfield Strait may be caused by a stronger surface current in this region. Organic carbon flux estimates in the eastern Bransfield Strait are the highest in the Southern Ocean, perhaps because of the fast sinking of fecal pellets, which leads to less decomposition of organic material in the water column. Approximately 5.8% of the organic carbon produced on the surface in the eastern Bransfield Strait is exported down to 1000 m; this percentage exceeds the maximum EF/sub 1000/ values observed in the Atlantic and Southern Oceans. The eastern Bransfield Strait appears to be the most important site of organic carbon export to the deep sea in the Southern Ocean.

  • The Korea Strait becomes deeper than 200 m from south to north in general except coastal area, whereas its southern part is shallower than 125 m except for a deep trough (Fig.1). The flow in the Korea Strait could be simplified as two layers (Isobe, 1995); the Tsushima Warm Water in the upper layer and the Korea Strait Bottom Cold Water (KSBCW) in the lower layer (Fig.2).
