An analytical model with three sub-regions for m2 tide in the yellow sea and the East China Sea
Ocean Science Journal - - 2005
Kyung Tae Jung, Chang Wook Park, Im Sang Oh, Jae Kwi So
In this study an analytical tide model of uniform width with three sub-regions is presented. The three-subregions model takes into account step-like variations in depths in the direction of the channel as a way to examine the M2 tide of the East China Sea (ECS) as well as the Yellow Sea (YS). A modified Proudman radiation condition has been applied at the northern open head, while the sea surface ...... hiện toàn bộ
Tidal and Sub-tidal Current Characteristics in the Kangjin Bay, South Sea, Korea
Ocean Science Journal - Tập 42 - Trang 19-30 - 2007
Young Jae Ro
This study analyzed the current meter records along with wind records for over 500 days obtained in the Kangjin Bay, South Sea, Korea spanning from March, 2003 to Nov. 2005. Various analyses include descriptive statistics, harmonic analysis of tidal constituents, spectra and coherence, the principal axis, progressive vector diagrams. These analyses can illustrate the response of residual current t...... hiện toàn bộ
Negative Impacts of Perkinsus olseni Infection in Manila Clam Ruditapes philippinarum Observed from Tidal Flats in Anmyeondo Island on the West Coast of Korea During Post-Spawning Period
Ocean Science Journal - Tập 56 - Trang 307-316 - 2021
Hye-Mi Lee, Kyung-Il Park, Hyun-Sung Yang, Kwang-Sik Choi
The high load of protozoan parasites in marine bivalves often leads to mass mortalities of the hosts. On the west coast of Korea in the Yellow Sea, the protozoan parasite Perkinsus olseni has been identified as the agent causing mass mortality of Manila clam Ruditapes philippinarum. During August and September 2004, mass mortality of clam occurred at Hwangdo (HD) tidal flat in Anmyeondo Island on ...... hiện toàn bộ
Use of Autonomous Reef Monitoring Structures to Monitor Changes in the Marine Environment in Jeju, South Korea: A Brief Review
Ocean Science Journal - - 2023
Hyun-Sung Yang, Taihun Kim, Kyeong-Tae Lee, Taeho Kim, David M. Baker, Do-Hyung Kang
Technology for monitoring natural environments can provide a basic understanding of ecosystem changes and information for resource management. The Natural Geography in Shore Areas project is an international collaborative effort for inventorying and monitoring marine biodiversity, and it indicates that Korea is one of the most species-rich regions worldwide. Rising sea surface temperatures due to ...... hiện toàn bộ
Interactive Effects of Ultraviolet Radiation and Dissolved Organic Carbon on Phytoplankton Growth and Photosynthesis in Sanya Bay, Northern South China Sea

Resource Assessment of Polymetallic Nodules Using Acoustic Backscatter Intensity Data from the Korean Exploration Area, Northeastern Equatorial Pacific
Ocean Science Journal - Tập 53 Số 2 - Trang 381-394 - 2018
Yoo, Chan Min, Joo, Jongmin, Lee, Sang Hoon, Ko, Youngtak, Chi, Sang-Bum, Kim, Hyung Jeek, Seo, Inah, Hyeong, Kiseong
A high level of confidence in resource data is a key prerequisite for conducting a reliable economic feasibility study in deep water seafloor mining. However, the acquisition of accurate resource data is difficult when employing traditional point-sampling methods to assess the resource potential of polymetallic nodules, given the vast size of the survey area and high spatial variability in nodule ...... hiện toàn bộ
4DVAR Data Assimilation with the Regional Ocean Modeling System (ROMS): Impact on the Water Mass Distributions in the Yellow Sea
Ocean Science Journal - Tập 53 - Trang 165-178 - 2018
Joon-Ho Lee, Taekyun Kim, Ig-Chan Pang, Jae-Hong Moon
In this study, we evaluate the performance of the recently developed incremental strong constraint 4-dimensional variational (4DVAR) data assimilation applied to the Yellow Sea (YS) using the Regional Ocean Modeling System (ROMS). Two assimilation experiments are compared: assimilating remote-sensed sea surface temperature (SST) and both the SST and in-situ profiles measured by shipboard CTD casts...... hiện toàn bộ
Induction of apoptosis by the tropical seaweed Pylaiella littoralis in HT-29 cells via the mitochondrial and MAPK pathways
Ocean Science Journal - Tập 48 - Trang 339-348 - 2013
Bo-Ram Ye, Junseong Kim, Min-Sun Kim, Jiyi Jang, Chulhong Oh, Do-Hyung Kang, Zhong-Ji Qian, Won-Kyo Jung, Il-Whan Choi, Soo-Jin Heo
We demonstrated that an extract from Pylaiella littoralis, collected from the Federate States of Micronesia (FSM), could inhibit the proliferation of tumor cells. P. littoralis extract (PLE) showed anti-proliferative activities in the tumorigenic cells tested, ranging from 20.2% to 67.9%. The highest inhibitory activity, in HT-29 cells, was selected for further experiments. PLE showed no cytotoxic...... hiện toàn bộ
Blooms of Trichodesmium erythraeum in the South Eastern Arabian Sea during the onset of 2009 summer monsoon
Ocean Science Journal - Tập 45 - Trang 151-157 - 2010
K. B. Padmakumar, B. R. Smitha, Lathika Cicily Thomas, C. L. Fanimol, G. SreeRenjima, N. R. Menon, V. N. Sanjeevan
This study presents in situ evidence for the blooms of Trichodesmium erythraeum observed in the shelf waters of the South Eastern Arabian Sea (SEAS) during the onset of the southwest monsoon in June 2009. Evidence showed that water surface discoloration was caused by the accumulation of T. erythraeum, and that the water column contained a colony of T. thiebautii. The surface water color in the blo...... hiện toàn bộ
