The (PacIOOS) based at the University of �鶹��ý at Mānoa is helping to enhance disaster and climate resilience in the Republic of Palau. Palau experiences frequent natural hazards, and the impact of climate change and sea-level rise has become a priority issue. Those extreme weather and climatic events often result in disruption of economic activity, and loss of people’s livelihoods.

A new Waverider buoy was deployed in Palau through an international collaboration. The buoy provides data—; ; and —will enhance disaster and climate resilience in the Republic of Palau. This wave buoy, the only Waverider in Palau, is located on the East side of the island of Babeldaob, about 1.4 miles offshore of Ngaraard State.

This effort is led by the Palau National Weather Service Office (NWSO) through the United Nations Development Programme (UNDP)’s Enhancing Disaster and Climate Resilience (EDCR) project, with PacIOOS serving as the technical partner.

“PacIOOS strives to provide timely, reliable, and accurate ocean information to enhance safety and resilience,” said Melissa Iwamoto, PacIOOS director. “As such, we are honored to collaborate with Palau NWSO and all the partners on this effort, and we are dedicated to enhancing the capacity in Palau to maintain these valuable ocean instruments to serve user needs.”

PacIOOS will continue to provide technical support as needed in the coming years. The buoy will also provide essential validation points for future development of a high resolution wave model for the island nation.

In addition to being a central user of the data, Palau NWSO will steward the Waverider buoy to ensure its ongoing operations and maintenance. Based on the experience gained from this project, Palau NWSO plans to expand the national wave buoy in the future with Green Climate Fund support managed through the UN Environmental Programme.

“Accurate and reliable wave and current data provide critical information to our weather forecasters, other agency officials, fishers, mariners and many other recreational and commercial ocean users to better understand prevailing ocean conditions and to make safe decisions,” said Maria Ngemaes, Palau NWSO meteorologist-in-charge. “The new wave buoy will help us to validate and/or compare satellite and altimeter derived information on the same variables that the buoy measures. It will also help us to monitor the conditions of the ocean in the event of severe weather and climate variability phenomenon, such as the extremes of ENSO: La Niña and El Niño, the monsoon, tropical cyclones, tropical disturbances and shear lines that dip near and north of Palau, as well as sea level characteristics.”

Supporting local efforts, future advances

Currently, PacIOOS also provides a . This is the first time PacIOOS has been a part of deploying and supporting a wave buoy in Palau.

While in Palau for the wave buoy deployment, PacIOOS wave buoy specialist Andreia Queima gave presentations to local agencies, organizations and communities that are interested to learn more about the buoy, the data it provides and how to access and use the data. She also worked with the Palau NWSO team to implement protocols to maintain the wave buoy.

To support ongoing efforts to sustain and enhance coastal and ocean observing in the U.S. Pacific Islands region, the (PacIOOS) received $4.26 million in federal funding. PacIOOS helps to increase ocean safety, protect public and environmental health and support the economy. This funding cycle marks the last year of a 5-year cooperative agreement with the U.S. Integrated Ocean Observing System.

PacIOOS, based at the University of �鶹��ý at Mānoa , currently owns and operates more than 35 observing platforms throughout the Pacific Islands region, including the State of �鶹��ý, the U.S. territories and U.S. Freely Associated States. PacIOOS also maintains modeling data that inform coastal, ocean and atmospheric forecasts.

PacIOOS information is used by the National Weather Service for ocean forecasts, harbor pilots for safe marine navigation, coastal managers for inundation forecasts and recreational users for surfing, fishing, boating and other activities. Accurate and reliable data of waves, currents, water quality, wave run-up and more can be accessed for free on the PacIOOS website via a variety of visualization tools that allow for easy access.

“PacIOOS observations from buoys, sensors, stations and animal tags provide information about the most recent coastal and ocean conditions, and the data help to improve short- and long-term forecasts. We are establishing time series that can record changes in the ocean environment and detect trends over time. Pacific Island communities are vulnerable to sea level rise and extreme weather events—our data empower decision-makers and coastal communities to make safe and informed decisions,” said Melissa Iwamoto, director of PacIOOS. “As PacIOOS embarks upon our 13th year in operation, we are grateful for the continued funding support and trust in our system.”

Expansion of observing assets

This year, PacIOOS also received funding from the U.S. State Department and is partnering with federal and local agencies to expand its network of real-time wave buoys in the insular Pacific. Large areas in the Freely Associated States currently lack real-time data, posing a safety concern both on land and in the ocean. Three new wave buoy sites are planned, and additional buoys will be available to maximize operational uptime. Capacity building and training are also in development to expand technical expertise among local partners and authorities.

Additional funding from NOAA will help replace PacIOOS’ aging instrumentation and infrastructure in �鶹��ý and increase observations in the insular Pacific. Plans are underway to provide real-time sea surface currents information between the islands of Guam and Rota (part of the Commonwealth of the Northern Mariana Islands), an area known for its challenging ocean conditions. Real-time and modeled data of currents are extremely important for search and rescue operations and to inform the safety of ocean users.

Contributing to national network

PacIOOS is one of 11 regional associations of the U.S. Integrated Ocean Observing System (IOOS®). More than $39 million was awarded in 2020 across the U.S. IOOS. Regional associations coordinate local coastal and ocean observing and decision-support projects to address community needs that integrate into the national system.

PacIOOS is currently developing a new (2021–2026) and a 10-year outlook. To provide suggestions and input, contact info@pacioos.org.

On May 10, 2019, the (PacIOOS) based at the University of �鶹��ý at Mānoa redeployed its wave buoy outside of Tanapag, Saipan, after it broke free from its mooring during Super Typhoon Yutu in October 2018.

The wave buoy was adrift for more than six weeks. In December 2018, approximately 800 nautical miles into the Philippine Sea, the U.S. Coast Guard Cutter Sequoia, stationed in Guam, recovered the buoy in challenging ocean conditions while patrolling the high seas.

The yellow wave buoy provides valuable and information. Data on wave height, direction and period, as well as sea surface temperature, are transmitted in real-time and are publicly available online.

“We are so grateful for the U.S. Coast Guard’s support and effort to recover the drifting wave buoy. Without their partnership, we would have lost this important ocean observing instrument,” said PacIOOS Director Melissa Iwamoto. “The buoy is now back on station and we are excited to continue to provide high-quality data to our stakeholders in Saipan and the region.”

The Tanapag wave buoy is one of three PacIOOS wave buoys in the Mariana Islands; the other two are located off Ritidian Point and Ipan in Guam. Wave buoy data benefit a large variety of ocean users, agency officials and community members to make safe decisions. Fishermen, surfers, commercial tour operators and many others regularly check the data to get a better understanding of the ocean conditions.

The U.S. Coast Guard recovered a drifting wave buoy deployed by the (PacIOOS) 800 nautical miles (NM) offshore from its original location off Tanapag, Saipan, in December 2018. The buoy broke free from its mooring in 20- to 25-foot seas when Super Typhoon Yutu directly hit the Mariana Islands on October 25, 2018. Rough storm and ocean conditions did not favor a speedy recovery, allowing the buoy to drift west in the Philippine Sea.

PacIOOS, based at the University of �鶹��ý at Mānoa , immediately notified the U.S. Coast Guard after the wave buoy departed. At the time, the U.S. Coast Guard was not able to assist with the retrieval of the drifting asset since all available units were focusing on comprehensive post-storm assessments and recovery efforts. Fortunately, all PacIOOS wave buoys are equipped with GPS, ensuring continuous monitoring and tracking of the buoy’s position.

Buoy retrieved and safely transported 46 days later

After 46 days, the buoy had drifted 920 statute miles (800 NM) offshore making recovery extremely unlikely. The crew of U.S. Coast Guard Cutter Sequoia, stationed in Guam, was patrolling the high seas, bringing the ship to “the neighborhood” of the buoy. Knowing the wave buoy and its associated data are extremely important to a variety of stakeholders, the crew temporarily diverted from operations to retrieve the buoy. Sequoia is an ocean-going buoy tender and regularly services large buoys and other aids to navigation. Despite the challenging conditions of 8 to 10-foot seas and 28–35 mph winds, the crew was able to retrieve the wave buoy using the installed crane and hydraulic equipment, and safely transported the buoy back to Guam.

Crucial data for ocean users

PacIOOS maintains a network of , three of which are located within the Mariana Islands (off and , Guam, and off , Saipan). It is one of 11 regional associations of the U.S. Integrated Ocean Observing System.

All wave buoys provide real-time information on significant wave height, period and direction, as well as sea surface temperature. The freely available data are crucial for federal and local agencies, as well as for commercial and recreational ocean users. Real-time ocean observations are limited throughout the region, magnifying the value and need of the PacIOOS wave buoys.

“We rely on a multitude of satellite data for issuing forecasts and advisories, but satellites only indirectly determine important ocean parameters. The PacIOOS wave buoys are our only routine source of directly measured nearshore ocean observations, allowing us to calibrate the satellite-derived ocean data,” said Roger Edson, National Weather Service Forecast Office Guam science and operations officer. “Waves can change dramatically in time and location so it is vital to have buoys in good strategic locations around the islands in order to be able to see approaches from all directions and ensure a 360 degree view.”

The (PacIOOS) deployed a on May 31. The buoy is located approximately 1.5 miles to the west of Kalaeloa Harbor on Oʻahu’s leeward side and provides real-time information on wave height, wave direction wave period and sea surface temperature.

Many commercial and recreational ocean users, as well as state and federal agencies, utilize PacIOOS wave buoy data to assess ocean conditions, allowing for safe operations and ocean use. Data from the Kalaeloa Barbers Point wave buoy, along with other PacIOOS wave buoy data, are available online.

PacIOOS Director Melissa Iwamoto stated, “The deployment of the Kalaeloa Barbers Point wave buoy was greatly anticipated by many of our users, stakeholders and partners, and we are thrilled that the buoy is now back on site. Our network of wave buoys collects important real-time wave observations in �鶹��ý and the Pacific Islands to inform and promote safe decision-making.”

Data empowers ocean users

PacIOOS empowers ocean users and stakeholders throughout the Pacific Islands by providing accurate and reliable coastal and ocean information, tools and services that are easy to access and use. PacIOOS is based at the University of �鶹��ý at Mānoa’s and is one of 11 regional associations of the U.S. Integrated Ocean Observing System.

Pat Caldwell, NOAA data center liaison and �鶹��ý surf forecaster, said, “We are excited that the Kalaeloa Barbers Point wave buoy is back in the water right in time for south summer swells. Reliable, real-time wave observations from the PacIOOS wave buoys are incredibly important to establish daily surf reports and to enhance our forecasting ability and accuracy. They serve as eyes on the ocean as they provide us with a constant flow of timely data, 24/7.”

Due to an increase in vessel traffic, PacIOOS acquired the necessary permits to relocate the previous Barbers Point wave buoy to a location slightly farther north. In its new position, the wave buoy will continue to collect accurate wave information for south and west facing shorelines.

Please stay clear of the buoy

To ensure continuous operation of the Kalaeloa Barbers Point wave buoy, vessel operators and ocean users are asked to stay clear of the buoy and refrain from tying to the equipment in order to avoid collisions and damage to the buoy. The mooring location of the buoy is included on nautical charts; however, boaters are reminded that the exact position of the wave buoy varies because of necessary slack in the mooring line.

PacIOOS owns and operates a network of 15 wave buoys in the U.S. Pacific Islands, 10 of which are located in the State of �鶹��ý. Another south-facing wave buoy will be redeployed in the upcoming months off ����Բ�ʻ��.

On June 6, the (PacIOOS) deployed a new wave buoy near the entrance to Pearl Harbor, approximately 1.5 miles offshore. The wave buoy provides accurate information on wave height, direction and period, and also measures surface currents and sea surface temperature.

Wave buoy data benefit the entire community and are important to make well-informed and safe decisions. Real-time wave information improves surf and ocean observations, and enhances wave modeling and surf forecasting. All wave buoy data are available online and free of charge.

“County, state and federal agencies, such as the U.S. Coast Guard, U.S. Navy and ��������’s National Weather Service, incorporate wave buoy data into their daily operational decision-making processes. Many commercial and recreational ocean users, community members, and researchers, also rely on the data,” said Melissa Iwamoto, director of University of �鶹��ý at Mānoa PacIOOS. “We are therefore extremely excited to offer a new observing asset to augment the existing network and better serve our community of users.”

The wave buoy off Pearl Harbor is the first PacIOOS wave buoy with the capability to measure surface currents at 10 minute intervals. Currents data, along with wave information, will help to enhance marine safety, navigation and harbor operations on ��ʻ�����’s south shore, in particular in the waters around Pearl Harbor.

The location of the buoy has been issued as a notice to mariners and will be included on nautical charts; however, the buoy is constantly in motion and can drift from its charted position. To keep the buoy and its sensors operational, vessel operators and other ocean users are asked to maintain a stand-off distance of at least 300 feet to avoid collisions and damage to the buoy. Boaters, kayakers and stand-up paddlers are asked to refrain from tying to the equipment and to avoid fishing near the buoy.

The �鶹��ý Natural Energy Institute at UH Mānoa provided the initial support to purchase this buoy with funding from the Office of Naval Research. The buoy joins a network of 15 real-time wave buoys across the Pacific Islands, owned and operated by PacIOOS. Data management for the PacIOOS wave buoys is made possible through long-term partnerships with the U.S. Army Corps of Engineers and the Coastal Data Information Program.

Wave buoy data benefit the entire community and are important to make well-informed and safe decisions. Ocean users, including fishermen, commercial operators, boaters and swimmers, can access all ocean data online, free of any charge. Real-time wave data are also vital to alert the community, emergency responders, and agency officials to big wave events that could potentially impact Guam’s shorelines.

“We are extremely excited that the Ritidian Point wave buoy is back in the water to provide real-time wave data. The buoy is a tremendous asset and a critical resource for us,” says Chip Guard from NOAA’s , Forecast Office in Guam. “We check the readings constantly to prepare our wave forecasts and evaluate the need for surf advisories and warnings and for small craft advisories.” Roger Edson, also of the Forecast Office, adds “It can really be helpful for flagging the largest waves during tropical storms and typhoons.”

In order to keep the buoy operational, ocean users are kindly asked to carefully navigate around the wave buoy, refrain from tying to the equipment, and avoid fishing within 100 yards to minimize entanglement in the mooring line.

Kimball Millikan, PacIOOS marine research engineer, states, “The wave buoys, and the sensors that lie within, are very sensitive. Any sort of collision or other abrupt impact can damage the instruments.” He adds, “the location of the buoy is included in all nautical charts, but keep in mind, these buoys are constantly in motion so the exact location varies.”

A new data set of the direction and speed of ocean surface currents in Hilo Bay is now available online. The hourly data updates are accessible to the public and free of charge on “Voyager,” the interactive mapping platform of the (PacIOOS) of the University of �鶹��ý at Mānoa .

Mapping ocean surface currents in near real-time provides valuable data for search and rescue operations by narrowing down the possible location of a missing person or vessel. The new data set also helps to forecast the distribution of oil or hazardous material spills and is therefore crucial to plan an adequate response. Marine navigation can benefit from near real-time surface currents for safe navigation. Other examples of surface currents data usage include water quality monitoring and forecast modeling.

“We are excited about the new ocean surface current data for Hilo. It complements the PacIOOS wave buoy and water quality buoy off Hilo Harbor,” said Jason Adolf, associate professor and chair of the at UH Hilo. “Providing data on ocean and water conditions, including waves and surface currents, in near real-time improves decision-making for ocean users, managers and responders. With the new data set we can also develop educational activities for the marine science curriculum at UH Hilo and raise public awareness in partnership with .”

If the ocean swell is too high, the safety of fishermen transiting out of the lagoon to open waters is threatened, homes and businesses may be flooded with seawater, roadways may become impassable and even the runway strip at the airport may be rendered useless for large commercial aircraft. This is the reality of islanders living on Majuro Atoll in the Republic of the Marshall Islands, and this is why providing near real-time ocean information to this part of the Pacific is a priority of the (PacIOOS).

Buoy deployed off eastern shore of Majuro

On July 10, PacIOOS collaborated with partners to deploy a new Datawell Directional Waverider buoy named Kalo about one mile off the eastern shore of Majuro. The buoy measures wave height, wave direction, wave period and sea surface temperature every 30 minutes. The PacIOOS wave buoy streams data to inform safe transit and recreation and provide critical information for the to produce accurate high surf forecasts and advisories and surf zone forecasts.

“Wave forecasting for the Marshall Islands is one of our most challenging tasks,” said Genevieve Miller, the meteorologist-in-charge of the (WFO Guam). “The PacIOOS wave buoy has been an invaluable tool in supporting our goals to better understand and predict damaging waves affecting Majuro.”

“PacIOOS has been a tremendous ally for us ocean wave forecasters west of the International Date Line,” added Chip Guard, the warning coordination meteorologist at WFO Guam. “The Majuro wave buoy has revealed many of the unique characteristics of the potentially destructive waves that threaten the atoll from the east, south and west. It will reveal more secrets, and we will eventually solve the wave forecasting challenge at Majuro.”

Wave buoy provides critical data

The direction of incoming swell is believed to be a critical feature affecting how much societal impact a particular event may have on Majuro. The PacIOOS wave buoy provides the critical swell spectra for ocean users, weather forecasters and researchers developing inundation forecasts for the atoll. PacIOOS hopes to use the data from the wave buoy to eventually develop a wave run-up forecast for the region, and this buoy will be a vital validation and accuracy tool for this effort.

PacIOOS requests boaters to steer clear of the buoy by 50 feet and not to tie off onto the buoy. The intricate mechanisms located inside render this buoy susceptible to damages. Recovery and redeployment of this buoy is expensive and challenging, as the team relies on calm ocean conditions to safely deploy these sensitive instruments that weigh 500 pounds.

�鶹��ý now has new ocean and coastal data available to inform weather forecasts and enable safer, more efficient marine transportation. On October 2, 2013, the Pacific Islands Ocean Observing System (PacIOOS), with support from , deployed a bright yellow wave buoy in over 700 feet of water about three nautical miles off Hanalei on the north shore of Kauaʻi.

The buoy measures wave height, wave direction, wave period and sea surface temperature. Scientists say the location off Hanalei is the best point in the main Hawaiian Islands to capture the dominant big swell during winter seasons. Wave buoys stream data to inform safe transit and recreation and provide critical information for coastal hazard and low-lying inundation forecasts for north-facing shores.

“There are active fishing and recreational communities on Kauaʻi that rely on accurate ocean forecasts to know when conditions are safe, and having a wave buoy in this location will improve these forecasts,” explains Heather Kerkering, PacIOOS director. “Data are updated every 30 minutes and broadcast on the .”
