Data provided by National Oceanic and Atmospheric Administration
Wave buoy 189 measures wave height, wave direction, wave period, and water temperature in the vicinity of Aunuu, a small island off the eastern coast of Tutuila in American Samoa. Data are transmitted every half hour. Moored in water 55 meters deep, this Datawell Directional Waverider Mark III (DWR-MkIII) buoy is equipped with three accelerometers measuring north/south, east/west, and vertical displacements, allowing it to measure both wave direction and wave energy. The temperature sensor is located at the base of the 0.9 meter spherical buoy, approximately 45 cm or 18 inches below the ocean surface. Wave buoys are useful tools for forecasting local waves and are used by recreational and professional ocean users alike.
