Pacific Whale Foundation has undertaken the Great Whale Count for the past 29 years. It is one of the world’s longest running cetacean projects involving citizen-scientists.

Citizen science is becoming a widespread tool for ecological and environmental monitoring, engaging members of the public, and promoting environmental stewardship. This systematic counting method allows us to monitor changes in humpback whale sightings from year to year and provides a valuable long-term snapshot of Hawaii’s humpback whale population.

Online registration for the Great Whale Count opens on December 15, 2018.
