We are in a race against time to discover ocean life before it is lost for generations to come. Ocean Census will create an immense wealth of openly accessible knowledge that will benefit and sustain all life on earth, for humankind and our planet.

Discover Life

The Ocean Census is the largest programme in history dedicated to discovering life in our ocean. Despite the vastness of the world’s ocean, only about 240,000 marine species have been documented—a mere 10% of what scientists believe actually exists. The Ocean Census seeks to address this significant gap in our knowledge.

Launched in April 2023 by The Nippon Foundation and Nekton, the Ocean Census is a global alliance that unites diverse skills and resources to discover and protect ocean life. This open network brings together philanthropy, government, and business with science, media, and civil society in a coordinated effort to vastly expand our understanding of marine biodiversity.

Through a combination of groundbreaking expeditions, cutting-edge scientific advancements, and innovative storytelling, the Ocean Census collaborates with ocean nations, philanthropic entities, governmental and commercial fleets, as well as subsea technology partners to explore biodiversity hotspots around the world.

A cornerstone of the Ocean Census is its commitment to open access and equitable data sharing. All scientific findings and information are made freely available to the global scientific community, decision-makers, and the public. By promoting inclusivity, transparency, and collaboration, the Ocean Census aims to drive positive change and inform effective conservation policies.
