Majuro Wave Buoy Redeployed to Serve Marshall Islands Communities

Majuro – The Pacific Islands Ocean Observing System (PacIOOS) redeployed its wave buoy outside of Majuro, Republic of the Marshall Islands (RMI). Located about 0.5 nautical miles (NM) off Delap Point, the yellow wave buoy measures wave height, direction, period, and sea surface temperature in 30 min intervals. All wave information is available online and free of charge. The reinstalled buoy joins the existing PacIOOS network of 13 real-time wave buoys across the Pacific.

Wave buoy data benefit the entire community and are important to make well-informed and safe decisions. Local and regional agency officials, boat operators, and other ocean users can access data online to get the latest observations. Real-time wave data are also vital to inform the community and emergency responders of big wave events that could potentially impact the Marshall Islands.

Through generous partner contributions, PacIOOS was able to fund and redeploy the new wave buoy southeast of Majuro. A previous buoy was lost at sea, most likely due to a vessel collision. Reggie White from NOAA’s National Weather Service Majuro Weather Service Office states, “The PacIOOS wave buoy is one of the RMI’s most important observing tools to assess ocean conditions and to evaluate the need for high surf as well as coastal inundation advisories and warning.” He adds, “As a low-lying nation, we are vulnerable to wave inundation and are dependent on accurate real-time data.”

Zdenka Willis, Director of the U.S. Integrated Ocean Observing System (IOOS), stresses, “We have a strong network of local, national, and international partners in the Pacific Islands region, who have shown their commitment to PacIOOS and its ocean observations. The remote location of the Pacific Islands is unique within the IOOS system and shows how valuable and impactful wave and ocean observations are on a daily basis to make safe decisions. IOOS and PacIOOS are committed to equip Pacific Islanders with the right data and tools to increase community resilience.”

In order to keep the buoy operational, ocean users are asked to stay 1NM off Delap Point to avoid collision and entanglement in the mooring line. Please refrain from tying to the buoy or fishing around it. The coordinates of the wave buoy are listed in nautical charts.

PacIOOS would like to extend a special thanks to NOAA’s National Weather Service Pacific Region Headquarters, the Republic of the Marshall Islands Government via the Climate and Oceans Support Program in the Pacific (COSPPac) of the Australian Government Bureau of Meteorology, U.S. IOOS, and an anonymous private donor (via the College of the Marshall Islands) for their financial support to fund the new buoy. Data streaming for the PacIOOS wave buoys is made possible through long-term partnerships with the U.S. Army Corps of Engineers and Coastal Data Information Program.

About PacIOOS

The Pacific Islands Ocean Observing System (PacIOOS) believes that ocean data and information can help save lives and resources. In collaboration with its partners, PacIOOS aims to provide sustained ocean observations in order to support decision-making and science for stakeholders who call the Pacific Islands home. Based within the School of Ocean and Earth Science and Technology at the University of Hawai‘i at Mānoa, PacIOOS is part of the U.S. Integrated Ocean Observing System (IOOS®).
