July 2001 : A Basic Plan for the establishment of the National Ocean
Observation Network was set up.
July 2002 : A Long-term Plan for the operation of Ieodo Ocean Station was
decided
June 2003 : Construction of Ieodo Ocean Station
Feb. 2006 : Internal Plan of the transfer of all ocean observation stations to
NORI was fixed.
2007 now : NORI operate all ocean observation stations including Ieodo
Ocean Station.
National Real-Time Ocean Observation Network
○ 91 observing stations will be established
by 2010 (59 stations , 2006)
- Ocean observation base : 5
- Lighthouse observatory : 20
- Dolphin observatory : 20
- Ocean buoy : 8
- Tidal station : 38
○ Ocean phenomenon such as tide,
wave, water temperature, current and
weather, etc.systematically is observed
and provided in real-time

Ieodo Ocean Research Station
Ocean Monitoring BuoyOcean Monitoring BuoyOcean Monitoring Buoy
○ Introduction- Provide boundary conditions for surgeprediction
- Complementary data supply for ocean current observation
- Acquisition of weather data in bad weather, such as typhoon and Produce current data
○ Application plan- Provide calibration and verification data for ship-mounted ADCP
- Calculation of boundary conditions- Long and short-term prediction of tidal and ocean current
Ocean Observation – Ocean Buoy
ARGOS BuoyARGOS BuoyARGOS Buoy
○ Introduction
- Observe typhoon using minimets and barometer
drifters
- Deploy the instrument using airplane (e.g.
Helicopter)
○ Application
- Provide SST, wind speed and air pressure at
typhoon core for typhoon prediction
- Provide calibration and verification data for storm
surge model
- Long & short-term prediction of ocean current

General type of buoy
Counter weight lowering the center of gravity
High Bending Radiuswith stress on cable and Instrumentation
Small Bending radius Giving very littleor no stress on cable and instrumentation
move up and down vertically
Acorn buoy is shaped for sub sea installations and to handle waves and swells

<Dropping position & way of a Drifting Buoy><Dropping position & way of a Drifting Buoy>
○ Dropping line of a buoy with Blue, Red, Green according to a path of a typhoon
○ A buoy keeps 30km interval and drops
○ A dropping of a buoy uses a parachute
