Today, let’s remind ourselves of an often-forgotten truth:

The ocean is our greatest ally against climate change.

It absorbs nearly a quarter of our CO₂ emissions, regulates temperature and climate…

And all of this thanks to invisible actors: marine microorganisms.

Plankton: the planet’s silent lung.

These billions of tiny organisms capture carbon and transport it to the depths.

This is the biological carbon pump, a vital mechanism to mitigate climate change… yet still largely unknown.

That’s why Pure Ocean supports the Microcean project.

The goal is to describe and decipher the role of oceanic microorganisms in climate regulation, and shed light on the challenges facing the deep ocean.

Understanding to better protect.

Knowing these species better means defending them more effectively against overexploitation, pollution, and the pressures threatening the deep ocean.

It also means better understanding how the ocean protects us every day.

On this World Climate Day, let’s never forget:

Protecting the ocean is protecting the climate.

Ocean Monday? ❌ Well… no, nothing to do with the ocean!

Blue Monday is considered the most depressing day of the year.

And yet, at Pure Ocean, we’re starting the week with great news: the High Seas Treaty has officially entered into force! 🎉

So what does this change? 👇

✅ International waters are now protected.
After more than 20 years of negotiations, 83 countries have ratified this essential agreement.

‼️ A legal gap has finally been filled: more than 60% of the ocean had little to no protection.

The high seas—over half of the ocean—had until now escaped any global protection framework. With the treaty’s entry into force, these international waters finally have shared rules to preserve their biodiversity.

⚖️ Clear rules for human activities.
Any activity likely to impact the high seas (extraction, aquaculture, etc.) will now be subject to an environmental impact assessment. This is mandatory for the 83 countries that have ratified the treaty.

🌱 Fair sharing of benefits from marine genetic resources.

The treaty establishes rules governing access to marine genetic resources and ensures that the benefits derived from their use are shared fairly among all countries.

🐋 Towards new marine protected areas.

Until now, less than 1% of the high seas benefited from official protection. With this treaty, the creation of vast marine protected areas in the high seas becomes possible—for the first time ever.

🔜 And this is only the beginning: a first global ocean conference will be held in New York by the end of 2026 to define the first concrete measures.

💫 On this Blue Monday, we choose hope.
It may not be Blue Monday for our mood…

But for the ocean, it’s clearly a day to celebrate! 💙

A month ago, we presented Flor Do Mar to you in preview… and since then, the video has already reached 31,000 views on YouTube! Incredible 🥳

Your enthusiasm and shares are helping this beautiful documentary travel far beyond the evening. THANK YOU!

✨ Thank you for your energy, your smiles, and your support throughout the year.
It is thanks to you that we can continue to protect the ocean and support scientific research. Without you, none of this would be possible.

🌊 The Ocean Night is a highlight every year: an opportunity to showcase our actions, connect, and above all, come together to celebrate what unites us. We can’t wait to see you again for the next edition!

In the meantime… relive the magic of the evening with our aftermovie.

Absolutely, your role can be concrete, and every action counts.

2025 was the Year of the Sea.

You may have already taken initiatives… but have you done enough? And above all, why stop there?

In 2026, the question is simple: will you remain a spectator… or turn this momentum into concrete and impactful actions? 👊

The ocean is essential to our daily lives. It provides us with oxygen, regulates our climate, feeds us, soothes us, and heals us. But it is fragile and under pressure. You can help protect it.

Not sure what to do? We have plenty of ideas for you ⤵️

You can financially support a scientific research project.

You can engage your teams in a field action, such as a beach or shoreline cleanup.

You can raise awareness among your colleagues with a scientific talk.

As an economic actor, you have a role to play. Your decisions can have a direct impact on the ocean and inspire thousands of people.

So what if, this year, your commitment to the ocean became a strategic and lasting decision?

Pure Ocean can help you turn intention into action. 💪

We don’t yet know if they dream in color, but one thing’s for sure: they literally change color while they sleep.

A finding that intrigued scientists at the Federal University of Rio Grande do Norte and Washington State University.

According to a study published in the journal Science, even when they’re asleep, octopuses remain surprisingly active: they move their arms, change their coloring and show intense brain activity.

They too have… sleep cycles.

The researchers observed that these phases resembled a very active sleep, comparable to that in which humans dream. This suggests that octopuses could be experiencing a form of “dreaming”… even if we don’t yet know exactly what’s going on.

Further proof that marine life is full of fascinating mysteries, even at rest.
