Hyo Choi is a Meteorologist, Environmental Scientist and Physical Oceanographer with over 40 years experiences in numerical modeling researches as Overseas Senior Researcher invited by Korean Government of Korea Ocean Research & Development Institute (KORDI of KAIST, (now, KIOST)), Ministry of Science & Technology, a high-level Researcher of National Fisheries & Research Development Institute (NFRDI) (nominated by President of Korean Government), Ministry of Maritime Affairs & Fisheries and Full Professor of Gangneung-Wonju National University. He has obtained 2 PhD degrees from Department of Civil Engineering, University of Texas at Austin, USA (1984) and College of Environmental Sciences, Peking University, Beijing; China (2004). His research interests cover a variety of fields in Meteorology, Environmental Science & Engineering and Physical Oceanography.. Presently, he is Director General of Atmospheric & Oceanic Disaster Research Institute, Korea, High-end Foreign Expert of South China Sea Institute of Oceanology, China and also acting as Editor-in-Chief of 13 international journals and Editor of 26 ones in atmospheric environmental pollution, disaster, agriculture, food sciences, water resources, lake and rivers, GIS, physical sciences, oceanography, fishery and meteorology.


The development of TY 1509, Chan-Hom under the associated with two different sizes of typhoons such as a smaller severe tropical storm and a stronger typhoon TY 1511 Nangka and a mid-latitude cloud trough was investigated using Korean satellite COM IRI images, weather maps and numerically calculated moisture fluxes and streamlines at 850 hPa level (approximately 1.5 km height above the sea surface) by a 3D-numerical model, called the UM-KMA meteorological model from July 4 through 10, 2015. Severe tropical storm Linfa and typhoon Chan-Hom maintaining their independent moving tracks did not have any interaction between them until July 5, 2015. However, TY Chan-Hom moving westward was strongly pulled north-westward by a mid-latitude cloud trough extending from the East China Sea to Hokkaido, Japan and further weakly drawn by SRS Linfa. From July 6 to 8, persistent north-westward STS Linfa was strongly pulled northward by more intensified TY Chan-Hom which was moving north-westward by strong south-westerly wind generated by the mid-latitude cloud trough in the north of Chan-Hom. The interaction of TY Chan-Hom with STS Lifa induced a shorter distance between two typhoon centers and TY Chan-Hom should be closed to Taipei. Even though Linfa was closed to Gangzhou in the southern China and its cyclonic circulation was weaken by big friction caused by surrounding land and shallower bottom topography of the South China Sea, it was still developed until July 8, due to the transportation of momentum from the stronger typhoon Chan-Hom and kinetic energy converted from the release of latent heat flux during the condensation process of supplied water vapor. From July 9 to 10, as TY Chan-Hom additionally interacted with TY Nangka in its east (the West Pacific Ocean) and continuously induced by the mid-latitude cloud trough, it should be more intensified. It means that windstorm over 25 kt was detected in the upper quadrant and right hand side of their cyclonic circulations, showing asymmetric distribution of wind fields. Under this circumstance, Chan-Hom could change its track from north-westward into northward, finally passing by the Yellow Sea without its landfall near Shanghai. Although the landfall of Linfa was delayed by the interaction of TY Chan-Hom, changing its moving track toward north-north-west, STS Linfa became weakened closing to the inland of Gangdong province, showing no longer tightly packed bands of cloud and being extinct.

Hans-Uwe Dahms has received his PhD and DSc degrees in Biology. He was invited to more than 80 countries worldwide for research and lecturing. He is presently a Professor at the Department of Biomedical Science and Environmental Biology in Kaohsiung Medical University, Taiwan. His current research is concerned with environmental health issues affecting public health.


Monitoring and assessments of the aquatic environmental health status should become integral components of adaptive management programs that are aimed to monitor and remediate pollution and the damage it causes to the aquatic environment. Such efforts taken separately may not be sufficient for detecting unwanted changes of integrative ecosystem health in a complex marine environment. Complexity is here provided by spatio-temporal gradients, such as geographic, latitudinal, depth, as well as seasonal shifts. In addition, organisms show commonly variable reactions at various levels of integration (e.g., at the level of genome and proteome, physiology, cell, tissue and organ, individual, population and community). Biota is also characterized by variability in their taxonomic and ontogenetic sensitivity and different reaction norms of sex. The tendency of most toxicants for differential individual bioaccumulation and biomagnification within food webs further complicates the situation. To date, only a few attempts have been made to challenge an integrative approach using, physical and chemical habitat assessments, biological monitoring and physiological, biochemical and genotoxicological parameters to assess the environmental health status of a contaminated aquatic ecosystem that could directly lead to food safety measurements in ocean fisheries and aquaculture. In order to integrate abiotic and biotic endpoints, different approaches should be pursued in a systems-oriented way: physical, chemical, biological; laboratory vs. field; realms (freshwater, brackish, marine-bottom, water column, interfaces); organisms (producer, consumer and decomposer); biological integration levels (ecological, behavioral, chemical and subcellular). This holds for observational monitoring as well as for experimental approaches at all integrations levels-from molecules to ecosystems. Challenges are provided at most levels of aquatic pollution: pollution monitoring, treatment and management, economic, social and policy aspects in the protection of the marine environment at National and International levels. Bioaccumulation occurs within a trophic level and represents the concentration increase of a substance in certain tissues of organisms due to absorption from food and the environment. Biomagnification commonly results from chemical persistence, food chain energetics or rate of internal degradation and excretion. For enhanced biomagnification, the pollutant must be long-lived, mobile, soluble in fats and biologically active. Among the newly emerging xenobiotics are endocrine disrupting chemicals (EDCs), capable of adversely affecting the function of endocrine systems, leading to changes in growth, development and reproduction of exposed animals and human. Although the occurrence and implications of steroid estrogens in the environment has received some attention, there is only limited evidence for bioaccumulation in wild or farmed fish that provide precious food sources for human consumption.

Zane Zhang has his expertise in stock assessment of fish population dynamics and environmental impacts on fished populations. He has used statistical models to provide scientific advices to fisheries managers, playing some key roles in successful management of several fishing stocks.


North Pacific albacore (Thunnus alalunga) are a highly migratory species. They start to mature at 5 years of age. Spawning occurs in tropical and sub-tropical waters between Hawaii and the east coast of Taiwan and the Philippines primarily in March and April. Juvenile albacore undertakes trans-Pacific movements between western and eastern Pacific Ocean. There has been a long history of exploitation of albacore tuna by many countries in the North Pacific Ocean. The Canadian tuna fishery catches juvenile albacore of 2-4 years of age using troll gear along the North American coast, primarily from the southern Oregon coast to the northern tip of Vancouver Island. The fishing season lasts from May to October with the peak of fishing effort in August and September. Canadian catches varied considerably primarily due to changes in albacore abundance. I used the catch rate (mean annual catch per vessel-fishing day) as an indication of the abundance. I examined impacts of local water temperatures and two climatic variables, the Pacific Decadal Oscillation (PDO) and the North Pacific Gyre Oscillation (NPGO), on the fluctuation of albacore abundance off the west coast of North America. The PDO is the dominant mode of variability of North Pacific sea surface temperature anomalies, while the NPGO closely reflects inter-annual and decadal variations in salinity, nutrient upwelling and surface chlorophyll-a in the Northeast Pacific. Mean water temperature in the fishing area during July-September was not found to be correlated with the abundance, statistically. The PDO, however, had a statistically significant (p<0.05) negative impact on the abundance with a lag period of 2 and 3 years. The NPGO had statistically significant positive impact on the abundance with a lag period of 2, 3 and 4 years. The current study helps in studying mechanisms of albacore recruitment fluctuations.
