○ Establishment and operation of observation system for synchronous continuous observation network of marine ecosystem
§ Necessity of the study
- In order to study the dynamics of marine ecosystem around the Korean Peninsula requires the time series data of species components of marine ecosystems. Because precise structural changes in the marine ecosystem provide the information about the healthiness of marine ecosystem, spawning period for the sustainable use of marine living resources and incubation fields.
- There are various institutes to accumulate the short/long-term studies of marine ecosystem in the Korean waters (Korea Institute of Ocean Science and Technology, National fisheries Research & Development Institute, Korea Marine Environment Management Corporation, Universities, Research Center companies). However, data merge is
difficult to analyze the marine ecosystem since the resolution for species discrimination has big difference depending on the data set.
- Traditionally, morphological characters are used to identify the marine species, but species identification shows uncertainty showing intraspecific or interspecific variation depending on the developmental stage. Recently, genetic traits of marine species are used as a criterion to identify the species.
- Species identification of marine organisms using molecular marker can be a standard method which is free from the status of species specimen and sequence of the analyzing time. Also, it shows the objective results.
- In order to establish and operate the observation system for synchronous continuous observation network of marine ecosystem, it requires stable collecting technique of specimen and standard method to identify massive marine organisms into the species level.
§ Objective of the study
- Establishment of observation system for synchronous continuous observation network of marine ecosystem
- Achievement of the observation technique for synchronous continuous observation network of marine ecosystem

○ Development of marine organism sampler on the wave glider
§ Necessity of the study
- It is hard to satisfy using conventional method based on the cruises to establish the synchronous continuous observation network of marine plankton ecosystem. Therefore, the development of unmanned autonomous sampler is required.
- Considering the features of marine plankton ecosystem, wave glider platform which does not need any electric power to operate in the sea surface is suggested. Although there has been various onboard sensors on the wave glider, sampling and analyzing system tools using the wave glider is rare globally.
- Therefore, it is essential to develop the marine organism sampler on the wave glider for expansion of the usability of wave glider and, establishment of observation technique for synchronous continuous observation network of marine ecosystem

○ Establishment and Operation of broad/ core observing network region based on the wave glider
§ Necessity of the study
- Almost domestic ocean observation methods using research vessels or fishing boats requires high expenditure and human resources, thereby there are a lot of limitations to do repeated surveys and marine
weather
- Developed countries have had limitations in the filed of marine research, introduction of the unmanned marine observation system has been processed actively since 2000.
- Underwater glider and Wave glider, as representative unmanned observation systems are already applying to observe marine observation after preliminary study actively.
- With technologies for the sensor and payload are developed and system integration technologies for marine observation are applied, various unmanned observation systems are introduced into developed countries such as U.S, Japan, France and U.K. Earlier, the point of observation is in the open ocean, but recently the locations are changed near to coastal points, which overcome the constrains existed previously.
- In addition to the introduction and utilization of abroad systems, to increase the efficiency of marine research, to develop the unmanned observing system is required. It requires the research for development of an optimized wave glider in the Korean waters for establishing the integrated marine observing system using wave glider

○ Development of Marine Ecosystem Modeling
§ Necessity of the study
Modeling system is a prerequisite for understanding, analyzing and predicting the marine ecosystem dynamics backing up the data insufficiency which is unavoidable in marine observation.
To secure the reliability of modeling system, however, it should be evaluated and upgraded periodically through the comparison with the in-situ data as many as possible.
Therefore, in order to make better use of the continuous pelagic ecosystem data observed at the specified points and times, a marine ecosystem modeling system should be developed that can make continuous and far-reaching diagnosis and prediction on the marine ecosystem of the waters around Korea,
Through this mutually beneficial study coupling the observation and modeling, it is expected that we can build up our scientific understanding of marine ecosystem as well as practical application using the optimized modeling system especially for the diagnosis and prediction of Korean waters.
§ Objective of the study
The goals of this study are to develop a state of art quasi-realtime simulation/prediction systems in order to analyze, evaluate and predict the major indicators of the pelagic ecosystem of the waters around Korea, and to understand the interaction between the changes of the physical environment and the marine ecosystem.
§ Contents of the study
Development of a bigger domain but coarser resolution marine ecosystem
model covering the East Asian Marginal Seas.
Development of a smaller domain but finer resolution marine ecosystem model for the waters around Korea
Improvement of the developed marine ecosystem modeling systems and development of a periodical (weekly or monthly) ecosystem assessment and prediction system
○ Establishment of Integrated management system of marine ecosystem and oceanographic data
§ Necessity of the study

Also it is necessary to establish the data management system to be able to take advantage of the execution of the analysis and ecosystem models of marine ecosystems, and to operate them.
