The largest global mission to discover
ocean life



Why
it
matters
Earth is the only known place in the Universe where there is complex biology. Ocean life has evolved over four billion years and is our planet’s superpower making all life on Earth possible – giving us our atmosphere, regulating our climate, feeding us and providing cures for our diseases.
Currently no more than 10% of ocean life is known, far less is protected and much is under threat.
Accelerating the discovery of ocean life advances fundamental ocean science, empowers marine conservation and fuels innovation.
To understand life, and sustain it, we must first discover it.

Join the census
The Census is jointly undertaken by the Ocean Census Alliance – uniting national and philanthropic marine institutes, museums and universities, backed by governments, philanthropy, business and civil society partners. The Ocean Census is reimagining discovery – fast, open, collaborative, equitable and at scale – to advance fundamental science, empower conservation and fuel innovation to sustain and advance life on Earth.

THE CENSUS IN ACTION
EXPLORE THE MISSION DISCOVER OCEAN LIFE
Expeditions
Our expeditions explore some of the ocean’s most under-surveyed, biodiverse and ecological regions. They focus on collecting specimens for scientific analysis and contribute vital data to the global marine species record. Click a location to learn more about each mission.
Species Discovery Workshops
These workshops unite taxonomists around the world to identify and catalogue marine species, using specimens collected from expeditions and museum collections. Select a workshop location to explore its outcomes.
