shipborne wave recorder (second sensor)
|Within Vocab||BODC parameter semantic model analytical method entity descriptions|
|Definition||A device for measuring height and period of sea-surface waves with two accelerometer and pressure sensor (inlet 1-2 m below the waterline) pairs mounted either side of the hull of a ship. The accelerometers measure vertical movement of the ship as it tries to follow each wave and the pressure sensors measure change in water height along the hull due to the ship's failure to follow the wave accurately. Combining the two gives the true wave height. Sensor pairs allow correction for rolling. Deployed on a package of instruments or sensors as the second sensor of this type.|
