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
Molecular Cloning, Characterization, and Expression of a Catalase Gene in the Japanese Scallop Mizuhopecten yessoensis Induced in the Presence of Cadmium
Ocean Science Journal - Tập 51 - Trang 223-233 - 2016
Jialong Gao, Shoichiro Ishizaki, Yuji Nagashima
Cadmium (Cd) is known to influence the oxidative status of marine organisms and can induce the formation of reactive oxygen species (ROS). Catalase (CAT) is one of the important enzymes involved in scavenging high levels of ROS. In present study, we cloned CAT cDNA and investigated the response of this enzyme at the transcriptional level in the Japanese scallop Mizuhopecten yessoensis exposed to C...... 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
Effects of temperature and salinity on survival rate of cultured corals and photosynthetic efficiency of zooxanthellae in coral tissues

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

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
R/V Isabu-Based First Ultraclean Seawater Sampling for Ocean Trace Elements in Korea
Ocean Science Journal - Tập 54 - Trang 673-684 - 2019
Suk Hyun Kim, Kongtae Ra, Kyung-Tae Kim, Hyeryeong Jeong, Jihyun Lee, Dong-Jin Kang, Taekeun Rho, Intae Kim
Trace elements (Mn, Fe, Co, Ni, Cu, Zn, etc.) are essential micronutrients for marine organisms and are thus related to major issues in the ocean, such as climate change, ecosystem change, and pollution. However, given their extremely low concentrations in seawater, contamination-free clean seawater sampling for trace elements onboard is the most crucial factor in this study. Because of the absenc...... hiện toàn bộ
