The mission of the Ocean Census is to accelerate the discovery of ocean life to advance fundamental science, empower conservation and fuel innovation to sustain and advance life on Earth.
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 Alliance is a growing network of scientists, governments, marine institutes, museums, philanthropy, technology, media and civil society partners working together to accelerate species discovery.
The Ocean Census Secretariat coordinates Alliance activities, managing and funding core programmes including expeditions, the Science Network, Species Discovery Workshops and Awards and the Biodiversity Data Platform.

Be part of the world’s largest effort to discover and document ocean life. At the Ocean Census, we bring together scientists, explorers, technologists, and communicators to accelerate species discovery and expand global biodiversity knowledge.
Uniting scientists from over 500 marine institutes to power the Census and scale species discovery – through expeditions, Species Discovery Workshops and Awards and give voice to the Census.
Enabling the Census to operate at scale – leading and participating in expeditions, workshops, unlocking legacy collections, data publishing, advancing related biodiversity research, and policy and public engagement.
Drawing on Ocean Census species data to underpin national and international climate, biodiversity, and development strategies and commitments – whilst helping to scale the Census through directing national research institutes, resources and capacity to participate in and contribute to the global programme.
Underpinning the Census, scaling species discovery in priority areas and advancing science, capacity development, policy implementation, innovation and ocean protection at national and global scales.
From data to sequencing, from marine operations to imaging, from finance to media, businesses deploy their skills, resources and brand power – serving to speed up, scale up and increase the impact of our mission – to discover ocean life.
Turning scientific discoveries from the Census into planetary action – and galvanise national and international programs to protect biodiversity, strengthen capacity and inspire public and policy engagement and action.

“We have 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.” – Yohei Sasakawa, Chairman of The Nippon Foundation
The Ocean Census, founded by The Nippon Foundation and Nekton in 2023, is the world’s largest initiative to accelerate the discovery of ocean life. The Impact Report 2025 report emphasises the urgent need for this mission: 90% of marine species remain undocumented, while extinctions are happening at over 1,000 times the natural rate.
Without faster discovery, many species will vanish before they are known.
The Ocean Census has proven that open, global collaboration can accelerate marine species discovery at unprecedented speed. By combining science, technology, and partnerships, it transforms curiosity into action—supporting biodiversity protection, scientific innovation, and long-term sustainability of ocean life.
