The Mayflower Autonomous Ship (MAS) is a grass roots initiative led by marine research non-profit ProMare with support from IBM and a global consortium of partners. Working in tandem with oceanographers and other vessels, MAS provides a flexible, cost-effective and safe option for gathering critical data about the ocean. It can spend long durations at sea, carrying scientific equipment and making its own decisions about how to optimize its route and mission.

This unofficial website documents the live data feeds, historical data as well as tutorials to use it and a showcase of projects made around the MAS. If you would like to contribute to this site, please visit and follow the contribution guide!
