Join our global network of sailors deploying low-cost sensor buoys to help scientists monitor ocean health, track climate change, and detect pollution patterns.
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.
Read Our Full StoryOur simple three-step process makes it easy for sailors to contribute to vital ocean research while enjoying their time at sea.
Sign up to receive your low-cost, maintenance-free sensor unit that's designed to be easily mounted on your boat.
The compact unit temporarily mounts to your boat and collects data without affecting your sailing performance or experience.
Your unit automatically transmits data to our network, helping scientists gather crucial information about our oceans.
Access comprehensive ocean data from a growing network of sailor-deployed sensors.
Our advanced sensor units can collect crucial data from both water and air, such as:

Help shape the next generation of our data collection devices.
"As a former America's Cup sailor and founder of a weather-tech company, I know how valuable accurate data is for understanding the ocean. SeaSense empowers sailors to collect data that helps scientists track changes in marine ecosystems."
"At Contest Yachts, we build yachts for sailors who explore the world: 'Building dreams together'. We believe that exploring also means understanding and caring for the oceans we travel."

"At Aknostic, we believe technology should enable independence and sustainability—values that perfectly align with SeaSense's mission to democratize ocean science."
