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

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
