Frequently Asked Questions

At what heights are the sensors located on moored buoys?

Meteorological sensors are normally located at the ten meter level for the 10-meter and the 12-meter discus buoys and are at a nominal height of five meters for the 3-meter discus buoys and the 6-meter NOMAD buoys. However, barometers are located inside the hull at the water level. Sea surface temperature sensors are located at a depth of 1.5 meters for 10-m and 12-m buoys and at 1 meter for all 3-m and 6-m moored buoys. Sea surface temperature sensors on NDBC buoys are located near one meter below the water line but they vary by hull type. Current hull configurations for water temperature sensors are: for 2.4- and 3-meter hulls at 0.7 meters; for 6-meter hulls at 0.8 meters; for 10-meter hulls at 1.1 meters; and for 12-meter hulls at 0.9 meters. Historically, water temperature sensors for 3-meter "foam" hulls were at 0.75 meters and 1.8-meter hulls were at 0.35 meters. Further information on buoy hull types is available.
