PacIOOS Wave Buoy 121: Ipan, Guam

Published by Coastal Data Information Program (CDIP) | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 26, 2026 | Last Modified: 2003-07-15T00:00:00.000+00:00
Wave buoy 121 measures wave height, wave direction, wave period, and water temperature in the vicinity of Ipan beach park near the village of Talofofo on the eastern coast of Guam. Data are transmitted every half hour. Moored in water 200 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.
