Station location chart of moored ocean data buoys
Moored ocean data buoy observations were made from 1978 through 2000 to obtain marine meteorological and oceanographic data in the seas around Japan.
Station location chart of moored ocean data buoys
Each buoy has a discus shape hull with a diameter of 10 meters. Sensors for air temperature, wet-bulb temperature, solar radiation and wind speed/direction are equipped on the platform atop the mast at 7.5 meters above the sea surface. Sensors for air pressure and wave height/period are installed within the hull, at levels close to the sea surface. A sensor for sea surface water temperature is equipped beneath the hull at 1 meter depth, and a couple of sensors are equipped on the mooring cable at 20 and 50 meters (or 50 and 100 meters) depth from the sea surface. The observation is usually carried out every three hours. When wind speed exceeds 35 knots each buoy changes the function automatically to one-hourly observation.
