Celebrating 30 Years of Sanctuary Ocean Count: A Community Science Initiative Transforming Whale Monitoring in Hawaiʻi
As January winds down, ocean enthusiasts across Hawaiʻi are abuzz not just in anticipation of warmer days but to celebrate a landmark achievement. This January marks the 30th anniversary of the Sanctuary Ocean Count, a pioneering community science program dedicated to monitoring the majestic humpback whales known locally as koholā that visit Hawaiʻi’s shores each winter.
What is the Sanctuary Ocean Count?
Since its founding, Sanctuary Ocean Count has invited residents and visitors alike to become stewards of Hawaiʻi’s marine environment. Participants track humpback whales in the shallow coastal waters where these giants migrate each winter to breed and nurse their calves. These areas serve as primary breeding grounds for the North Pacific humpback whale population, which spends summers feeding in Alaska’s colder waters.
Today, the Sanctuary Ocean Count captures one of the largest seasonal gatherings of humpback whales in the world, with estimates exceeding 12,000 whales visiting Hawaiʻi annually. The program has forged a unique connection between these magnificent animals and the local community, fostering awareness about conservation, responsible whale-watching practices, and marine stewardship among countless volunteers.
The Journey Begins: From Humble Origins
In the early 1990s, the Hawaiian Islands Humpback Whale National Marine Sanctuary was newly designated and sought ways to deepen understanding of local whale populations. Sanctuary Ocean Count emerged from this need, designed to engage the public in research and observation.
The first official count occurred in February 1996 on Oʻahu, involving around 150 volunteers equipped with binoculars and an eagerness to observe humpbacks. Since then, the program has expanded to over 60 sites across four islands and now engages more than 1,000 active volunteers, who collectively donate over 3,000 hours annually to support marine research.
Since 2019, Sanctuary Ocean Count has partnered with the Pacific Whale Foundation’s Great Whale Count on Maui, combining resources and data for a more comprehensive statewide assessment of humpback populations.
Driving Data and Discovery
Each year from January through March, volunteers take positions at designated coastal observation sites on the last Saturday of the month. They tally whales and record behaviors, building crucial datasets for researchers. Observations include surface activities such as blows, breaches, tail slaps, and even interactions with other marine life.
Observation sites vary in orientation, elevation, and accessibility, offering volunteers diverse perspectives of Hawaiʻi’s complex marine environment. This diversity enriches the volunteer experience and strengthens the dataset that underpins scientific research. By participating, volunteers become integral to a collective effort, enhancing the sanctuary’s outreach while deepening public understanding of marine ecosystems.
Community Science: The Heart of the Initiative
The impact of community science is profound. NOAA, which oversees Sanctuary Ocean Count, defines it as collaborative projects where volunteers join researchers to address real-world environmental challenges.
Through active participation, volunteers gain first-hand experience in data collection, analysis, and reporting. Their efforts transcend simple observation. They help break down barriers between science and society, broadening understanding of marine life and fostering environmental literacy.
Portraits of Passion: Inspiring Future Ocean Stewards

Cindy Among-Serrao, Hawaiʻi Island program coordinator for Sanctuary Ocean Count, describes the energy during these events as palpable, noting the joy in seeing families come together to observe and learn. Volunteers interact with more than 1,000 community members annually, sharing knowledge about the sanctuary, its inhabitants, and the importance of citizen science, cultivating the next generation of ocean stewards.
Join the Celebration: How You Can Participate
Those inspired by this milestone can mark the last Saturdays in January, February, and March 2026 to participate. Volunteers contribute to ongoing whale monitoring and help protect marine ecosystems while celebrating community engagement and environmental dedication.

The Bigger Picture
The 30-year legacy of Sanctuary Ocean Count highlights the broader importance of community-driven conservation. In an era of climate change and environmental challenges, this program demonstrates the power of collective action.
Volunteers are not merely counting whales. They are contributing to vital research, promoting stewardship, and reinforcing the connection between humans and the ocean. Every observation aids scientists in addressing pressing questions about marine populations and ecosystems.
In the larger framework of conservation, Sanctuary Ocean Count exemplifies how individual efforts, dedication, and passion can combine to produce meaningful results. Together, communities can foster a more resilient and informed approach to protecting marine life.
As we celebrate three decades of this extraordinary program, one thing is clear. Every count matters, and every effort contributes to preserving Hawaiʻi’s marine treasures for generations to come.
