MISSION
We are an international network of researchers, communicators, and explorers committed to advancing research, education, and sustainability on the Earth’s oceans. With our low-impact, low-cost research expeditions on sailboats, we do groundbreaking research on topics ranging from microplastic pollution to environmental DNA.
We have reached the remotest corners of the planet, from the edge of the North Pole to Antarctica, but our mission goes beyond discovery.
Our specialty is connecting scientists with passionate and engaged sailors worldwide and effectively communicating about these collaborations to raise awareness at all levels.
What we offer
unique blend of research, engagement, and communication.

citizen science
Bringing together scientists and volunteers to amplify the impact of scientific findings
science Communication
Sharing science and building lasting bridges between science and society
events
Connecting people with the oceans to promote sustainability, adaptation, and innovation

ONE OCEAN, ONE FLEET: THE POWER OF LIGHTWEIGHT, SUSTAINABLE SAILING
Science on board
“The Science we need for the Ocean we want” is the motto of the Unesco Ocean Decade Initiative, highlighting science’s crucial role in preserving our oceans. Oceans cover 71% of our planet’s surface and hold 97% of its water. Home to over one million (known) species, oceans are essential to life on Earth, regulate our climate and weather, and protect us from global warming.
By contributing to science and engaging the youth and the public in the research process, we want to amplify the impact of scientific findings while promoting sustainability, collaboration, and innovation.
Our scientific programme includes sampling plastic and microplastic in the sea, drone mapping of plastic pollution along the coasts, satellite ground-truthing, eDNA sampling, drone mapping of uncharted land territories, cosmic ray measurements, and marine archeology.
