Just One Ocean

Just One Ocean 'Without the oceans, life on earth cannot exist, including us'. Dr Sylvia Earle. Our ocean is under threat from all manner of pollution and human activity.

We rely on our oceans for our very survival yet we continue to use it as a place to dispose of things that we don't want, whether it is a plastic bottle or chemicals we put on our gardens and crops. It all ends up in our ocean

Often this is done inadvertently through poor waste management processes, but much of it is down to us. Human neglect and behaviour is the biggest problem and it something that we can change - if we want to. We continue to fish at levels that are just not sustainable. Trawling methods and the resultant by-catch often results in huge areas of the seafloor being denuded of all marine life. In our lifetimes we have virtually wiped out several popular species of food fish. In Japan, the capture and brutal slaughtering of dolphins results in worldwide condemnation, yet still in continue. And millions of sharks are killed every year, at a rate that they cannot recover from, purely to satisfy the Asian appetite for shark fin soup which is primarily seen as a status symbol. We have to change our behaviour and Just One Ocean is all about change. We want to engage with people, to try to change behaviour and attitudes, not only of the general public but also large corporations, and governments. We want to provide resources that can help make those change, whether they are educational materials or a range of products that will help you to make sustainable choices. Choices that not only protect our oceans, but also generate revenue for further research, engagement and education. With this we can support targeted solutions to ensure that plastic pollution does not continue to pollute the ecosystems that we are so reliant upon, and that we use the gift of our ocean responsibly.

🌊 Take on a challenge for the ocean in 2027

Looking for something incredible to aim for next year?

Just One Ocean is once again part of the Ultra Challenge Series, giving you the chance to walk, jog or run some of the UK's most spectacular routes while raising money to support ocean conservation.

You don't have to be an ultra-runner. With distances from 10 km to 100 km, you can choose a challenge that works for you — whether that's your first 10K, a 25K walk, a 50K challenge or the full 100K.

You'll have a fully signed route, rest stops, food and drink, medical and welfare support, and a finish-line celebration waiting for you.

Every kilometre helps protect the ocean.

Challenge yourself. Protect our ocean. 🌊

What’s happening beneath the surface?

When we look at the ocean, we see the waves, the colours, and the amazing marine life. But there’s so much more happening beneath the surface that we can’t see.

At The Coral Tribe, our interns get the chance to become ocean scientists, testing the water to better understand the environment our reefs call home.

We check things like temperature, salinity, dissolved oxygen, pH, nutrients, and water clarity, small pieces of information that tell us a lot about the health of the ocean.

Why does this matter?
Corals are living animals that need the right conditions to survive. Even small changes in the water can have a big impact on the reef and everything that depends on it.

By understanding the ocean, we can help protect it. 💙

“Before we can help protect the reef, we need to understand how our actions affect it.”

Everyone who joins our Marine Conservation Program signs an Environmental Agreement. It’s a simple reminder that you’re not here just to dive or volunteer, you’re here to actively contribute to marine conservation.

It sets out the basics of being a responsible diver: good buoyancy, keeping off the reef, never touching corals, and respecting marine life.

Most importantly, it means students, interns, and staff all follow the same environmental standards and understand that the way we dive and behave can have a real impact on the reef.

At the Houses of Parliament for the launch reception of the APPG report on microplastics. Some outstanding work by Antaya March, Cressida Bowyer, Felicity Webster and other co-authors from the Revolution Plastics Institute on this report. It presents some solid and, importantly, achievable recommendations and hopefully will help to kick start change and reduce the problem here in the UK.

Small but important.

The banded coral shrimp (Stenopus hispidus) is more than just a colourful reef resident. Acting as a cleaner, it removes parasites and debris from fish, helping maintain the health of the reef community.

Every species has a role to play. 💙

Another fantastic day of citizen science on the beaches of South Cornwall.

These photos show exactly what the Big Microplastic Survey is all about—carefully collecting data, following a simple scientific method, and helping build a clearer picture of where microplastics are found and in what quantities. Every survey adds another piece to the puzzle. Together, thousands of surveys from around the world are helping us understand the abundance and distribution of microplastics on our beaches, providing valuable data for research, conservation, and future decision-making.

The best part is that you don't need to be a scientist to make a genuine scientific contribution. Whether you can complete one survey or one hundred, your data matters. So next time you're off to the beach, why not take the The Big Microplastic Survey with you? Spend some time collecting data, enjoy being outdoors, and become part of a growing global community helping us better understand one of the biggest environmental challenges facing our ocean.

We’re delighted to announce a new partnership between Just One Ocean and Sycomore!

Sycomore bridges the gap between science and art to create powerful, tangible solutions to today’s environmental challenges. By collaborating with leading artists and scientists, Sycomore creates art collections inspired by particular issues, with proceeds supporting projects that address them.

Each artwork sold in their Oceans collection will support our Big Microplastics Survey, with Sycomore’s unique Impact Legacy™ Score transparently measures the real-world impact each piece of art achieves.

Here is a beautiful contribution by Basmah Omar, ‘Above’s Destructive Shadow.’

If you’d like to get involved, whether by contributing or buying artwork, donating to the cause or helping Sycomore reach a wider audience, they would love to hear from you!

Find out more via their website https://sycomore.org/ or LinkedIn https://www.linkedin.com/company/sycomore-solutions/

Humans have more in common with these elite ocean predators than often thought. A little Miles Davis anyone?
