Citizen Science Ocean Monitoring —
Sail with Purpose.
Join our global network of sailors deploying low-cost sensor buoys to help scientists monitor ocean health, track climate change, and detect pollution patterns.
About Project SeaSense
Project SeaSense is an innovative climate initiative that combines sailing and citizen science to monitor our oceans. We're creating a global network of ocean sensors by equipping sailors with sophisticated monitoring buoys that collect vital data to support scientific research and environmental protection.
