NOAA NDBC Moored Buoys

Anchored to the ocean bottom, these buoys float at the water surface carrying an array of meteorological and oceanographic instrumentation. The National Oceanic and Atmospheric Administration (NOAA) National Data Buoy Center (NDBC) moored buoys measure and transmit barometric pressure; wind direction, speed, and gust; air and sea temperature; and wave energy spectra from which significant wave height, dominant wave period, and average wave period are derived. The direction of wave propagation is also measured on many moored buoys.
