World leaders gathering for the COP28 climate summit have been given a stark warning by leading scientists in the Ocean Census alliance, whose aim is to discover and protect 100,000 new marine species in the next decade. 




World leaders gathering for the COP28 climate summit have been given a stark warning by leading scientists whose aim is to discover and protect 100,000 new marine species in the next decade.  

Speaking from Tenerife, where The Nippon Foundation-Nekton Ocean Census alliance has launched its latest subsea mission, its science director Professor Alex Rogers says COP decision makers must ‘act now’ before global warming leads to entire marine species and their habitats becoming extinct.

The need to recognise we are in “a race against time” to prevent species loss was echoed by renowned Tenerife taxonomist Leopoldo Moro - who is co- directing the Ocean Census Canary Islands expedition and who is a leading authority on the impact of biodiversity loss in the region.

The Ocean Census mission is deploying the Pisces VI submersible to find new species down to depths of 300m.

The Canary Islands, of which Tenerife is perhaps the best well known internationally after recent forest fires ravaged vast tracts of land, are experiencing rising ocean temperatures and ever more present weather pattern changes and storm surges.

In one small village on Tenerife, residents of Bocacangjero report storms impacting their homes both from the sea when the tide is high and from the mountains above as flood waters gush through ravines onto their rooftops.These real-time changes, mirrored across the globe, have prompted a chorus of calls to COP leaders at their 28th summit to take action.

Ocean Census Science Manager Verity Nye warned the impact on people’s lives is only going to get worse. Her colleague Emily Cunningham, a well known ocean advocate from the UK, described the loss of each species as another instrument in the orchestra of life being silenced. It was, she said, “the soundtrack to extinction”. 

But the team of scientists assembled for the Ocean Census expedition is not preaching a message of unbridled doom - early dives off Tenerife and work done by participants on reconnaissance dives ahead of the mission offer hope of species, new to science, being found in the waters round the island.The hope is, by assembling an international team of expert taxonomists and by using cybertechnology techniques to speed  specimen identification, the scientists on location can fast track protecting species before it's too late and propel Ocean Census towards its goal of discovering 100,000 new species in the next decade.

SOUNDBITE Dr Leopoldo Moro, Ocean Census Mission Co-Leader (SPANISH)"The objective of this mission is to inventory marine fauna before climate change and anthropogenic pressures make this fauna disappear. And this is a work against the clock. We need to move forward as soon as possible because we are losing species day by day. [00:05:57][12.8]

13. SOUNDBITE Professor Alex Rogers, Ocean Census Science Director(English)

[00:06:44] The ocean is on the frontline of climate change. Everywhere we go now in the ocean, we see the signature of climate damage, climate disruption. Marine life is on the move from the tropics to the poles. We're seeing species being pushed to the brink of extinction simply because the ocean is warming up.

15. SOUNDBITE Professor Alex Rogers,Ocean Census Science Director (English) "Leaders of COP your decisions are critical in the survival of a significant proportion of marine life. If you fail to act now, the oceans will continue to warm. We see continued sea level rise. We see continued deoxygenation of large parts of the ocean and we'll see continued ocean acidification. And the result of that will be extinctions in the ocean.

21. SOUNDBITE Verity Nye, Ocean Census Science Manager (English) "It's evident that people on this island are already feeling the impacts of climate change and sea level rising. And COP leaders there need to take notice of that. Listen to what people are saying. Look at the evidence and start taking action because this is already impacting people's lives. And that impact is only going to keep getting more significant. "

23.SOUNDBITE Emily Cunningham, Ocean Census Scientist: "If you imagine all of biodiversity as the most wonderful orchestra you have ever heard, playing the most beautiful piece of music, and each of those little creatures in the ecosystem, they're an instrument within the orchestra. And so you need all of them together to have that beautiful music. Every species that we lose is an instrument lost from that. So over time, it gets poorer and poorer, and you have just these random instruments playing in the kind of chamber of silence that's the soundtrack to extinction, and that's what's happening in the biodiversity crisis.

What is Ocean Census?

Ocean Census is the largest programme in history to discover life in our ocean. It will be launched on April 27th, 2023 and will herald a new era of pioneering research and scientific exploration to accelerate species discovery and protection. Recent technological advances in high resolution imaging, DNA sequencing, and machine learning mean scientists can now massively accelerate the process. 

This will revolutionise our understanding of marine life which lies largely undiscovered beneath the waves. Today, scientists believe they have described little over 10% of the species that exist. It is believed there are 2.2 million species in our ocean, to date about 240,000 have been described.

Ocean Census has set the ambitious target of finding at least 100,000 new marine species in the first decade.  

We currently describe only around 1,700 – 2,000 new ocean species a year. The time from discovery to registration of new organisms can vary greatly depending on the species, existing species knowledge, the research entity, research method, and level of identification. This currently takes as little as one to two years and as long as several decades. That rate of discovery has changed little since the 1800s. 

Who is involved in Ocean Census?

Ocean Census is a global collaborative initiative, an open network of science, business, media and civil society organisations joining forces. It has been founded by The Nippon Foundation, a private, non-profit foundation for social innovation, and Nekton, a UK-based marine science and conservation institute. 

What is the estimated cost of Ocean Census?

The cost of Ocean Census is dependent on how large the initiative grows. Whilst the Nippon Foundation is providing the project’s initial core funding, the alliance of partners involved are committing their own resources to the global effort. 

Why is it taking place? 

Ocean life is fundamental to all life on Earth. It produces the oxygen we breathe, isolates carbon dioxide, creates food for billions of people and is constantly providing vital scientific advances to fight disease. 

We urgently need to protect this precious resource and the life within it, but we can’t protect what we do not know. 

Ocean Census will help to significantly advance our understanding of fundamental science – oxygen production, carbon cycling, sustainable food production, the evolution of life on Earth and discoveries of new medicine and biotechnologies. 

Ocean Census will help to identify how marine ecosystems are responding to climate change, assessing how marine life could support climate adaptation and alleviate the impacts of climate change for the benefit of all. A recent IPBES-IPCC Co-Sponsored Workshop Report on Biodiversity and Climate Change showed strong linkages between measures to mitigate and adapt to climate change and biodiversity.

How will Ocean Census work?

  • Scientists from across the world will embark on expeditions to the ocean’s biodiversity hotspots to find new life from the surface to full ocean depth (10,925 metres). 
  • Specimens will be sent to Ocean Census Biodiversity Centres which harness technological advances across high resolution imaging, DNA sequencing and machine learning to speed up and scale up the process of discovery. 
  • As more partners get involved in high, middle-and low-income nations, more scientists and centres will participate.
  • Networks of taxonomists will connect virtually to draw on the aggregated data set created which will provide a complete picture of species discovery and description.
  • This aggregated, open-sourced data is added to a network of data centres globally and made freely accessible to scientists, marine policymakers and the public. We are working with these data centres to increase interoperability with a goal of having a single point of access - the Ocean Census Biodiversity System for scientists, decision makers, and the public.

Why should I care? 

Ocean life makes all life on Earth possible and holds the wisdom of four billion years of evolution on Earth (life has existed in the ocean for three times longer than land). For context, 33 phyla are known in the Tree of Life, of which 32 are found in the ocean and 17 on land and in freshwater. Phyla are the major branches of ‘The Tree of Life’, how life is classified. Life in our ocean is responsible for much of the air we breathe, regulating our climate and Earth’s chemistry, and a vital food source for billions. To sustain and benefit life on Earth, we need to understand, protect and restore ocean life.

Who owns the data, is it ethical to take samples from the ocean, particularly in developing countries?

All data is open access for science, decision makers and the public for non-commercial use. All expeditions and research is co-produced hand-in-hand with host nation scientists and governments and the species, specimens, and related data discovered from territorial waters are owned by the host nation (under Nagoya Protocol and related laws). Under the UN Law of the Sea, species, specimens, and data from international waters are part of the collective commons, owned by the people of the planet and all data is open access for the common benefit of humankind. 

Who will name the species?

Species from a nation’s territorial waters are given Latin names by the scientists doing the

species descriptions where at all possible, in consultation with host nation scientists. A smaller number of species will be given Common Names by the people of the host nation of each expedition in a process that will be managed and guided by the scientists from the host nation. Species from international waters are given Latin names by the scientists doing the species descriptions with a small number of species to be given Common Names by the public. These protocols will be established in the first phase of the programme.

Isn't it all too late and the ocean is doomed?

No, it's not too late. 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. 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.

What does success look like and how will it be measured?

Success for us is ultimately helping inform the protection and restoration of ocean life so it can continue to support life on Earth. This requires a lot of other global issues to line up towards this outcome which are outside of our control. However, in terms of our contribution it will be measured by:

  • The number of species discovered – the goal is at least 100,000. Each one represents a vital piece of the code of life on earth - the more we discover, the more we understand how life exists and how to sustain and strengthen life in the ocean and therefore on Earth. 
  • The range of discoveries which will benefit all humankind – from oxygen production, carbon cycling, sustainable food production, the evolution of life on Earth and discoveries of new medicine and biotechnologies.  
  • The number of scientists involved, particularly taxonomists. Currently taxonomists are declining in number and are usually found in high-income nations. Success will be growing a network of scientists engaged in the discovery and conservation of ocean life – and notably, far more equitably distributed across the global ocean.

We have heard that many pharmaceuticals and cures have been found in the ocean. What do you expect to find? 

Marine genetic resources are the genetic material present in all marine life and have been a source of many important pharmaceuticals, nutraceuticals, and personal care products (e.g., currently 13 pharmaceutical drugs derived from marine organisms have been clinically approved, including treatments for cancer, neuropathic pain, COVID-19, HIV-AIDS and antivirals, with a further 24 marine-derived products in clinical trials and 250 in preclinical investigations). 

Harnessing marine genetic resources will galvanise marine biotechnology industries including through the discovery of new drugs to treat disease and identifying bulk eco-chemicals and sustainable bioplasticsHowever, Ocean Census is not involved in bioprospecting nor any onward commercialisation.

Is the extraction of coral & other samples a harmful process?

Ocean Census will deploy high-precision sampling tools to collect corals and other large organisms. This means that a small number of individual samples will be collected and then preserved for further classification in museums or other laboratories. Sub-samples will be taken for DNA analysis. These organisms will be killed as part of this process but the number of samples will be minimised.

Smaller organisms that live in sand or mud will be collected as small samples of sediment, preserved and then later extracted. Again, bare minimum sampling will be undertaken.

Ocean Census may opportunistically collect specimens from fisheries surveys or other sources. These organisms would usually die as a result of collection but in this case they will be preserved for scientific description.

Are you using larger vessels to carry out the research, is this not bad for the environment?

Ocean Census will combine vessels from the philanthropic, government academic and commercial fleets. We are deploying a combination of advanced subsea technologies with divers, human submersibles, and remotely operated vehicles (ROVs). At present these vessels are generally powered by fuel oil and these do have a CO2 footprint. Our shore-based and nearshore expeditions will have a much lower carbon footprint. As the programme continues overtime, large hydrocarbon-powered vessels will likely be replaced by vessels powered by ammonium or hydrogen.

What if we fail?

The loss and destruction of ocean life is an existential crisis. Without ocean life, life on Earth will not continue as we know it. The more we can do right now, the more positive the impact we can have down the tracks.
