  1. Ocean Observation System In Korea

  2. NEAR-GOOS was Selected as a Pilot Program of Regional GOOS because the existing ocean observing system around in this region was Intensive. However, the development was much slower than its youger sisters in other region. What’s the reason ? Example of NFRDI’s bi-monthly oceanographic survey for more than 60 years

  3. Brief Introduction to Ocean Observing System in Korea

  4. Serial Oceanographic Observations (NFRDI) 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. China Serial Oceanographic Observations • 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 Yellow Sea NFRDI 14 layer

  5. Oceanographic Observations using Ferry (NFRDI) - Six times (round-trip)/week - From August 2006 - Parameters : temp., Sal. - Three times (round-trip)/week - From August 2006 - Parameters : temp., Sal.

  6. Master Plan for National Real-time Ocean Observing System, 2002

  7. Water Level Observing Network (Tide stations) (NORI) NORI Tide stations (NORI)

  8. Coastal and Ocean Observing Network (KMA) KMA 2009 Tower 2008 Buoy 2010 Light tower 2008 Parameters : Wind, Air temp., Air pressure, SST, Wave

  9. Wave Observation in Korea

  10. Light tower Pier Coastal tower Ieodo station Buoy (10m) In situ Real-time Observation (KORDI) Ocean buoy (10m) KORDI Coastal tower Light tower Ieodo (’03) Pier Ieodo Station

  11. Observation sensors at IEODO station (KORDI)

  12. Planed as Chin-Korea Joint Ocean Data Buoy But deployed as a Korean Buoy, Sept. 2007

  13. ARGO, KORDI and KMA

  14. Sites of Coastal Erosion Monitoring System Location map of coastal erosion history survey(120 sites)

  15. National Earth Observation Satellite Plan in Korea Communication, Ocean and Meteorological Satellite (COMS) will be scheduled for launch in June 2009 Ocean Color 2006 KOMPSAT-2 SAR Ocean color

  16. National Earth Observation Satellite Plan in Korea Near future Earth observation Satellite Launch plan • COMS : Communication, Ocean & Meteorological Satellite • There is no KOMPSAT-4 satellite because of his serial number “4” (死)

  17. - 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 forRT 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

  18. 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 InternationalProgram

  19. 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

  20. YOOS Design Principles (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. 20

  21. 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

  22. 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

  23. Local Ferry Routs in Korea and between Chinese ports and Incheon 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 • temperature, salinity, pH, DO, chlorophyll and • turbidity and also GPS positioning system.

  24. East/Japan Sea: ARGO Yellow Sea : ? - Drift buoy: just for surface - Ferry Box (Cooperation with China) - Near-real time operation of oceanographic survey (NFRDI) - Buoy with vertical observation of U.V and T,S Necessity of near real-timeobservation of 3-D structures
