  • As a result of continuous taxonomic investigations of Korean crabs, Pugettia intermedia Sakai, 1938 is newly reported from Korean waters. Pugettia intermedia had previously been reported in Korean fauna, but the previous reports of P. intermedia were resulted in misidentification of P. quadridens (De Haan, 1839). Pugettia intermedia differs from P. quadridens in having two subequal medial lobes of the first pleopod in male. In P. quadridens, one of the two medial lobes is about half-length of the other. Pugettia intermedia occurs on the southern coast of the Korean peninsula. The descriptions and illustrations of this species are provided herein.

  • As a part of the commemorative joint faunal survey for the 30th anniversary of the Korean Society of Systematic Zoology, the molluscan fauna of Jindo Island was investigated based on sample collection from 6 localities from the 6 to the 8 of Jul 2016. A total of 114 molluscan species from 47 families were collected and identified. Among these, 42 species from 11 families are newly reported from Jindo Island and combining the previous records with the present study totals 157 species from 57 families. Distribution of species records indicates that marine biogeography of Jindo Island represent an overlapping zone for marine organisms which dwell in the Yellow sea and the southern sea areas of Korean waters.

  • Distribution, population structure, and growth of the bivalve Protothaca euglypta were investigated for clams collected from the northwestern part of the East Sea of Russia. This species is distributed in further northern area than it was found earlier. In the southern area, this clam is found in the intertidal zone, up to 8 m in depth. It is one of the most numerous infaunal species of bivalves, and protected to wave action in the gravel-pebble and sand with rubble biotope. Population density of P. euglypta reaches 500 $spc./m^2$, and biomass 2 $kg/m^2$. Size and age composition of the local settlements and allometric growth of P. euglypta depend on a biotope. The growth rate of P. euglypta considerably reduces in case of the northern boundary area, whereas life span increases.

  • The time variation in the Kuroshio is studied by use of nine observed distances of the main Kuroshio axis from the Japanese coast. The observed distances over 1975 - 1995 are estimated from the Prompt Report of Oceanographic Conditions published by Hydrographic Department of the Maritime Safety Agency of Japan. It is shown that large sea level difference between Naze and Nishinoomote, which represents the volume transport of the southern inflow south of Kyushu, coincides with larger distance of the Kuroshio in the upstream area from off Kyushu to off eastern Kii Peninsula and smaller distance in the downstream area from off Omae-zaki to off Boso Peninsula. In contrast, large sea level difference between Nishinoomote and Aburatsu, which represents the volume transport of northern inflow south of Kyushu, corresponds to smaller distance in the upstream area and larger distance in the downstream area. Path dynamics of the Kuroshio is discussed with reference to the variation in Volume transport south of Kyushu.

  • Three barracudina fishes (Paralepididae) were newly recorded from the southern sea of Korea. Lestidium prolixum is characterized by a single band of luminous ducts on the midventral line and absence of a papilla anterior to the eye. Lestrolepis intermedia and L. japonica are similar in having a black papilla immediately in front of the eye and two bands of luminous ducts on the midventral line. However, the dorsal fin of L. intermedia is located more posterior along the body than that of L. japonica, and L. intermedia have larger number of anal fin rays 42 (vs. 36-40) and vertebrae 95 (vs. 86-87) than L. japonica.

  • One specimen of Chirolophis saitone, belonging to the family Stichaeidae, was collected by a bottom trawl in the southern area of the Yellow Sea. The present specimen was characterized by 52 dorsal fin spines, 38 anal fin spines, a caudal fin with four vertical dark bands and an orbital region with three pairs of branched cirri. We propose a new Korean name, "Jak-eun-goe-do-ra-chi', for C. saitone.

  • Tsushima Warm Current(WD entering into the East Sea through the Korean Strait flows northeastward and during this travel it shows complicated movement like meandering and eddy. It is considered that these variations of TWC are important causes making water masses unstable and also have influence on biological and chemical properties of water masses. Lee and Cho(2000) suggested that meandering of TWC in adjacent waters of Noto peninsula has much influence on fluctuation of current structure. (omitted)

  • In this study, we applied the teleseismic receiver function technique to determine the crustal thicknesses and ratios for 31 broadband stations of the Korean Peninsula and map out the lateral variation of Moho depth in the Peninsula. The estimated depths to Moho range from 26 to 35 km except for an island station ULL (17 km). The Moho is turned out to be deeper in the south-western part of the Peninsula and western Gyeongsang basin, and shallower in the off-shore region close to East Sea (Sea of Japan). The ratio varies from 1.69 to 1.89 with the average of 1.77, which is close to global average (1.78) in the crust.

  • The 29 May 2004 offshore Uljin, Korea earthquake was predominantly thrust-faulting at a depth of approximately 12 (±2) km. The mainshock attained the seismic moment of M0 =5.41 (±1.87)  1016 N m (Mw = 5.1). The focal mechanism indicates a subhorizontal P-axis trending 264° and plunging 2°. The orientation of P- and T-axis is consistent with the direction of absolute plate motion generally observed within the plates, hence the cause of the May 29 shock is the broad-scale stress pattern from the forces acting on the downgoing slab along the Japan trench and inhibiting forces balancing it. The 29 May 2004 earthquake occurred along a deep seated (~12 km), pre-existing feature that is expressed on the surface as the basement escarpment along the western and southern slopes of the Ulleung basin. The concentrated seismicity along this basement escarpment suggests that this feature may qualify as a seismic zone - the Ulleung basement escarpment seismic zone (UBESZ).

  • I in this article analyzed poetry and prose written by Ming Navy forces who visited Chungcheong Navy Castle(忠淸水營) in Ocheon(鰲川) during Japanese Invasion of Korea in 1592(壬辰倭亂) and the remains concerning them. Chungcheong Navy Castle was used as a way station when Ming Navy forces came and went to the Southern Sea during Japanese Invasion of Korea in 1592. In April 1598, "Gyegong cheongdeok bi(季公淸德碑)" was erected to praise Gyegeum for his virtue. The villiagers have served "Gyegeum cheongdeok bi" as a god for the peaceful sea and good luck from the ancient times. Zhang Liangxiang(張良相) & Jia Xiang(賈祥) developed his great spirit to appreciate beautiful viewwhen he defeated Japanese force and ascended again to Yeongbo Pavilion(永保亭).
