Brief Introduction toOcean Observing System in Korea
![Page 4: Ocean Observation System In Korea](https://reader035.vdocuments.mx/reader035/viewer/2022062809/56815a03550346895dc74feb/html5/thumbnails/4.jpg)
The serial oceanographic observations have been carried out from 1921 in Korea. The present-day 207 stations from 25 observation lines have been set up. The survey cruise is implemented bimonthly for the waters around the Korean Peninsula and 4 times a year in the East China Sea. The following parameters are observed and analyzed.
Seawater temperature and salinity Dissolved oxygen Nutrients nitrates, nitrites, silicates, phosphates Zooplankton biomass Chlorophyll-a concentration Meteorological factors air temperature, air pressure, wind direction and speed, cloudage and cloud form, wave direction and height

- Operational Service System is not fully operational (Except Meteorology)
=>The use of other‘s real-time data is not urgent -> No intent to take effort to provide data to others => No Data Exchange
Build sub-regional Operational Oceanographic System for Data Production and Service
=> Need for RT data exchange will become urgent => Active RT data exchange among neighboring countries => Benefits of global observing system would be acknowled and appreciated => Accelerate regional observing system as an element of GOOS, and hence GEOSS
Prblems in Ocean Data Exchange
![Page 18: Ocean Observation System In Korea](https://reader035.vdocuments.mx/reader035/viewer/2022062809/56815a03550346895dc74feb/html5/thumbnails/18.jpg)
•Fill gaps in density of data platform (Meteorology and Oceanogr. Jointly) - using existing structures : light buoy, tower, structure - Upgrade existing observation or survey system like NFRDI’s ocean survey program for near real-time opr. - Technology development (ex. ground radar..), application
• Regional/sub-regional Cooperation - Cooperation with China, North Korea for Yellow Sea YOOS(Yellow Sea Operational Oceanogr. System)
• Operational data product and service system essential Benefit of R-GOOS, GEOSS, Real-time data exchange, Fill the gaps
• Participation in International Program

Realtime Observation System using other marine facilities - Offshore Navigation Towers - Coastal Piers - Gas/Oil production tower – Navigation Buoys
How to persuade the owners to cooperate - Communication channel - Benefit through the outcomes of the real-time obs. System - Contribution to marine community - Support from regulating agencies
Examples Offshore light tower Gas Production Platform Coastal Piers Large scale coastal development

YOOS Design PrinciplesYOOS Design Principles ( (borrowed from US-GOOS, need to be modified)borrowed from US-GOOS, need to be modified)
• Enable users from both private & public sectors to
• Routinely, reliably & continuously serve data on core variables in forms & at rates specified by the users.
• Share data & information produced at public expense openly & fully in a timely fashion.
• Adhere to regional standards & protocols
• Build on, improve & enhance existing capabilities over time.
• Improve the capacity of all the region to participate in & benefit from the YOOS.
• Implement YOOS approved performance measures for all of the above.

Observation System
( Expensive, Need Cost efficient approach)
-Multi-function of ocean observing system
-Extension of the existing coastal observation system
-Making most of the existing facilities .
-Real-time telemetry system for coastal waters
- Governance duplication problem

Cooperation for Regional GOOS i). Boundary Conditions for coastal models to solve various coastal problems need be obtained through regional or basin-scale models covering all the regional area. ii). Neighboring countries normally have common problems in coastal disasters induced by the same kind of events. iii). Neighboring countries share a common interest in preserving and managing the marine environments and resources of the regional sea.
Obstacles to realtime exchange of the ocean observation data i). Not much experience with data exchange or benefit from data sharing ii). Conflict with national interest (Security and Pollution Problems) ii). Technical Problems
How to overcome the obstacles in ocean data exchange The most essential matters in promoting regional observing systems is that each participating country recognize the benefit of regional cooperation especially in coastal hazard reduction

-temperature, salinity, pH, DO, chlorophyll and -turbidity and also GPS positioning system.
Limitation of Buoys and Towers . Difficult to cover wide area . Difficult in maintaining the Sensors for Chemical, Biological Parameters => Ferry Boat Monitoring Most Efficient Method of Marine Env. Monitoring Bi-lateral cooperation is essential for regional seas
