Ocean Census: 100,000 new species in 10 years

Today, Ocean Census, the largest programme in history to discover life in the ocean has been unveiled with the ambitious target of finding at least 100,000 new marine species in its first decade.

A “race against time” to discover ocean life has prompted the launch of Ocean Census, a global initiative that wants to revolutionise ocean protection.

Scientists believe little more than 10% of what lives in the ocean has been found, while they estimate that there are around two million species still undiscovered. The ambitious Ocean Census endeavour builds on major programmes of the past including The Challenger Expeditions (1872-1876, the birth of modern marine science) and The Census of Marine Life (2000-2010).

Founded by The Nippon Foundation, the largest non-profit foundation in Japan and Nekton, a UK-based marine science and conservation institute, Ocean Census will operate as a global collaborative initiative that will see science, business, media and civil society organisations, including Oceanographic Magazine, joining forces.

“We have a short window of opportunity, perhaps the next ten years, when the decisions we all make will likely affect the next thousand or even ten thousand years,” explained Oliver Steeds, Ocean Census director and chief executive of Nekton. He added: “Some people are saying ‘it’s time to go big or go home’. We’ve chosen to go big, and we hope the giant leaps in knowledge we can make with the discovery of ocean life, can help put us on a better track towards a positive future for people and the planet.”

Throughout the next few years, Oceanographic Magazine will act as the official photography partner for Ocean Census. This will involve finding suitable photographers and deploying them on expeditions amongst other tasks. Steeds commented on the alliance with Oceanographic: “We can’t protect what we don’t know exists. Whilst Ocean Census has an ambitious goal of discovering 100,000 species in the coming ten years, to make real change happen, people need to fall in love with the wonder and majesty of what lives in our seas. Oceanographic are brilliant storytellers and photographers and working together we can hopefully further inspire both the public and decision makers to act.”

For the past 200 years, taxonomy work, the art of finding and scientifically describing species, has been a slow, methodical process and the average rate of new species discovery hasn’t changed much since the 1800s. It currently stands at around 2,000 a year. The Ocean Census alliance believes that traditional taxonomy is unable to meet the challenges of the climate and biodiversity crises that will result in the loss of the majority of species on Earth, scientists expect.

“Revolutions in technologies such as digital imaging, sequencing and machine learning, now make it possible to discover ocean life at speed and at scale,” said professor Alex Rogers, Ocean Census science director. He continued: “It currently takes one to two years to several decades to describe a new species after it is collected by scientists but utilising new technologies and sharing the knowledge gained using cloud-based approaches, it will now only take a few months.”

Over the coming years, scientists from around the world will embark on dozens of expeditions to the ocean’s biodiversity hotspots to find new life from the surface to full ocean depth. Combining vessels from the philanthropic, government and commercial fleets, they will be deploying a combination of advanced subsea technologies with divers, submarines and deep-sea robots.

Yohei Sasakawa, chairman of The Nippon Foundation, commented: “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, for humankind and our planet. Ocean Census is full of dreams and wonder, and cannot be accomplished by the Nippon Foundation and Nekton alone. We would like to unravel the mysteries of the ocean, in collaboration with ocean research institutes, businesses, governments, the public, philanthropy and civil society.”

“The beauty and diversity of marine life in the Ocean is still beyond human comprehension, but as we explore and uncover what lies beneath the sea surface, we are constantly awed and delighted by new lifeforms,” shared Dr Jyotika Virmani, executive director of Schmidt Ocean Institute, one of the leading partners of Ocean Census. “Schmidt Ocean Institute is proud to be partnering with Ocean Census to accelerate our understanding of the incredible creatures that inhabit our marine world,” continued Virmani.

Species discovered on expeditions will be sent for high resolution imaging and DNA sequencing in a network of Ocean Census Biodiversity Centres to be established in high, middle, and low-income nations around the world. Networks of taxonomists will then connect virtually to draw on what Professor Rogers and his scientific team calls ‘Digital Life Forms’ to complete species descriptions.

The aggregated, open-sourced data will be added to a network of data centres globally and made freely accessible to scientists, decision makers, and the public.

“This new foundation of knowledge can help advance our understanding of fundamental science – oxygen production, carbon cycling, sustainable food production, the evolution of life on Earth and even discoveries of new medicine and biotechnologies,” revealed Mitsuyuki Unno, executive director of The Nippon Foundation. “Through advancing our understanding of the abundance, diversity and distribution of life in our ocean, we hope Ocean Census will catalyse global efforts to conserve our ocean,” Unno added.

Ocean Census is coming at the right time as the 2022 Montreal Biodiversity Conference made the decision to protect 30% of our planet for conservation of life by 2030. Implementation of this ambitious policy in the ocean will need the information provided by Ocean Census to ensure that protected areas are optimally positioned to protect biodiversity.

The UN Biodiversity Beyond National Jurisdiction treaty agreed in March 2023 means that there is now a legal framework to establish such protected areas in the high seas. Lack of progress on prevention of global warming detailed in the IPCC 2023 Climate Report emphasises the urgency of action to understand the ocean and its potential responses to climate change as well as potential to mitigate emissions and adaptation through nature-based solutions.
