When The Great Reef Census set out to map the health of the Great Barrier Reef, it needed more eyes than any research team could provide. Enter students. Through the Great Reef Census Schools Program, run by Citizens of the Reef, classrooms around the world have become citizen science labs, combining the human eye with AI technology to generate vital reef data.
The program is simple in design but significant in impact. The Citizens of the Reef team delivers a one-hour presentation (via video call for New Zealand), training students to identify plating, branching and boulder corals. Students then analyse real images from reef surveys, providing coral cover and category data that feeds directly into conservation actions.
Over 5,000 students from around the world, including schools in Aotearoa, have already taken part. In 2025 alone, students analysed 37,308 images across 60 participating schools. This contribution helped the Great Reef Census survey over 25% of the Great Barrier Reef, up from below 5% before the Census began. In real numbers, more than 229,673 reef images have now been collected from over 868 reefs.
For teachers, the appeal is a low-effort, high-impact addition to the curriculum. For students, it's a genuine stake in real-world science.
"My Marine Studies students have proudly participated in The Great Reef Census every year since 2021," says Dr Deb Geronimi of Camden Haven High School.
"This experience not only makes their learning deeply meaningful, but also gives them a powerful sense of achievement, knowing they are contributing to the real-world conservation of one of the most spectacular ecosystems on the planet."
For students, it gives them a practical way to work with possible eco-anxiety and feel like they are making a genuine impact on the future of their world.
Parents notice the difference too. One mother described watching her son analyse survey images "on a Friday night when he avoids school homework like the plague," adding that "the ocean and sea life is his happy place."
This year, the Great Reef Census has launched pilot programs across the world, including the Coral Triangle (a reef network stretching from South East Asia to the Solomon Islands), the Red Sea and Hawai'i.
More reefs mean more images to analyse, and today's students, fluent in technology, are perfectly placed to help.
Independent schools across New Zealand are warmly invited to join. To find out more about getting your classroom involved, visit Citizens of the Reef or The Great Reef Census, or contact them directly at schools@citizensgbr.org
