The Network
What started as a pilot research project on the Great Barrier Reef has grown into a global network of groups testing sea-weeding

AUSTRALIA
Earthwatch pioneers collaboration between scientists, volunteers and communities to drive meaningful behaviour change, with citizen science being the global biodiversity framework at its core.
In collaboration with James Cook University, a leader in marine science, Earthwatch Australia co-founded the initial sea-weeding program on the Great Barrier Reef, providing the scientific foundation that led to this global network.
SEYCHELLES
Nature Seychelles, founded in 1998, is a leading conservation NGO managing Cousin Island Special Reserve and driving projects in endangered species protection, coral restoration, climate action, education, and environmental policy.
Over recent years, Cousin Island Special Reserve has faced severe macroalgal takeover, particularly Sargassum spp., threatening both natural reefs and restored sites. In 2026, we commenced a study to address this escalating challenge.
SINGAPORE
The Reef Ecology Lab is based at the Department of Biological Sciences, National University of Singapore. Their research focuses on the diversity, ecology and restoration of coral reef ecosystems in Singapore and the Southeast Asian region.
Coral reef sites being sea-weeded in Singapore are highly urbanised environments, nestled in an extremely busy port area, with high levels of sedimentation and turbidity.
MOZAMBIQUE
Love The Oceans is a grassroots marine conservation organisation committed to protecting our planet’s oceans through innovative, community-driven solutions.
This site was established in 2025, after long-term monitoring showed that turf-forming algae have taken over. The team is testing an innovative underwater scrubber to remove turf from around individual coral colonies.
