Our raison d’être

Dive differently, understand and protect the ocean.

The genesis

What if every dive had meaning?

As consumption accelerates, even in the diving world, the race for the spectacular shot, for bucket-list destinations and ever more intense experiences often takes over.

Further. Rarer. More impressive. But then what? What really remains of a dive once you are back home?

What if we slowed down? What if we chose to dive differently? What if every immersion became a chance to learn, to understand, to contribute?

We know diving is not the most neutral activity for the planet, the carbon footprint of long-haul travel is real, and we don’t ignore it. Yet it isn’t about giving up diving: it’s about rethinking the way we do it. Giving meaning back to every immersion, pairing the useful with the unforgettable, turning every trip into a concrete contribution to the oceans we come to explore.

It is in exactly this spirit that Blue Mind Expeditions was born.

Who are we?

Two enthusiasts, one project.

Blue Mind Expeditions was founded by Margaux Le Brun and Anthony Le Floc'h, two marine-life enthusiasts whose paths crossed underwater… and never parted since.

Co-founder · Senior Marine Technician (Marine Environment Engineering) · Naturalist & expedition guide

Margaux Le Brun

A marine biology graduate, professional diver, underwater photographer and camerawoman, she devotes her work today to education, awareness and the conservation of the marine environment. Before specialising in shark diving, she took part in coral restoration and repropagation projects in Indonesia, developing early on a hands-on approach focused on action and the protection of ecosystems. She has guided hundreds of divers worldwide in encounters with the great marine predators, always aiming to promote respectful, safe ecotourism that benefits local communities and the environment. Beyond expeditions, Margaux takes part in audiovisual and documentary projects committed to the ocean. She notably contributed, as mission photographer and second underwater camera, to a UNESCO-backed documentary film in the Azores, alongside Roberto Rinaldi, the renowned cameraman of Jacques Cousteau.

Anthony Le Floc'h

Driven by boundless curiosity, Anthony has explored some of the most varied environments on the planet, devoting nearly 15 years of his life to the ocean in all its forms. Along the way, he has logged more than 9,000 dives, building a deep and lasting bond with the marine world. For several years, he directed and managed dive centres in Africa and the Maldives, guiding thousands of divers across some of the most beautiful sites in the world. Passionate about passing on knowledge, he has also trained hundreds of divers of all ages and levels, from their very first bubbles to advanced certifications. A dive instructor, naturalist guide and multilingual expedition guide: French, Italian, English and Spanish. Anthony is also a certified technician for the Cressi, Mares and Scubapro brands, ensuring complete expertise, from the water to the equipment. Over the past five years, offshore diving and shark diving have become the heart of his practice, leading him to some of the most intense and wildest experiences the ocean can offer.

Both stand for a more conscious, responsible vision of travel and diving. Tired of the greenwashing so common in tourism, they set out to create expeditions where you no longer simply “observe” nature and consume diving, but genuinely learn, understand and contribute.

Above all, Margaux and Anthony seek to rebuild the bond between people and the ocean, and to show that more conscious, more respectful, more useful tourism is not only possible but necessary. Together they offer trips at the crossroads of discovery, citizen science and good company, human expeditions you come back from transformed.

Our vision

No longer
“consuming” diving.

Diving is a privilege, one we believe can be exercised responsibly and meaningfully. At Blue Mind, we refuse passive diving: the kind where you go down, watch in silence, come back up and move on to the next without really understanding what you saw.

We believe, on the contrary, that wonder is even more powerful when fed by knowledge. That you observe better what you understand. That the connection with the living world runs deeper when you know who is in front of you, how it lives, what threatens it, and how you can help.

So every trip is designed to be an experience of the mind as much as the body. We dive (or snorkel), yes. But we also learn. We talk, we debate, we meet. And often, we contribute to something bigger than ourselves.

How it unfolds

What happens on a trip.

Our trips take two main forms, depending on the place and context.

Citizen-science trips

Become part of the research. When a scientific collaboration is in place, the trip becomes a true field expedition: every immersion turns into a guided, fully explained data-collection session.

Scientific briefings before each dive to understand what you will observe and why.
Photo-identification and laser photogrammetry to estimate the size of individuals, yes, you’ll learn to “measure” a shark underwater.
Image-analysis workshops: identify individuals, build a register, detect each animal’s unique signatures.
Talks on the ecology of the species, its behaviour and its conservation status.
A real contribution: your data is shared with researchers and feeds databases that serve long-term conservation.

Educational trips

Learn to see differently. When a scientific protocol isn’t at the heart of the trip, the focus shifts to educational immersion, the keys to understanding what you observe, with an accessible approach.

Talks on the species you’ll encounter: cetaceans, elasmobranchs (sharks, rays), fish, corals and reef ecosystems…
Naturalist briefings before each outing: behaviours, interactions, indicators of ecosystem health.
Conversations about the threats and the conservation actions under way.
Debriefs after each session: understand what you saw, share, sharpen your eye.
Underwater photo and video tips, beginner or advanced, to bring back images that mean something.

Who is it for?

For everyone, really.

You don’t need to be a seasoned diver, or even a diver at all. A passion for the marine world doesn’t depend on a certification or a dive count in a logbook.

Divers of every level, from curious beginners to seasoned divers seeking new meaning.
Snorkellers and freedivers, many magical encounters happen just a few metres below the surface.
Photographers and videographers, pro or amateur, for a unique setting and high-impact images.
The curious and the passionate, who want to know everything without necessarily getting wet (or barely).
Committed travellers, looking to align their holidays with their values.

What matters is your mindset. Curiosity and a willingness to learn are enough. We take care of the rest.

The vibe

Science, the sea… and joie de vivre.

Scientific and educational rigour doesn’t mean austere seriousness. No military atmosphere, no rigid protocol: we learn while laughing, we share over a meal, we debrief the dives feet in the sand watching the sunset.

Joining a Blue Mind trip means joining a community. You’ll meet people who share your passions and values, divers, photographers, biologists, students, travellers… brought together by the same spark.

You come for the animals. You leave with friends.

Why it matters

Why is this important?

The oceans cover more than 70% of the planet, produce half the oxygen we breathe and regulate the climate. Yet they are under threat: plastic pollution, acidification, warming, overfishing, habitat destruction…

The knowledge that informs decisions and conservation is sorely lacking for many species. This is where citizen science comes in: by involving passionate citizens, we multiply observation capacity and produce valuable data at large scale.

And beyond the data: we create ambassadors for the ocean. Because protecting the ocean also starts with how we choose to explore it.

Join the adventure.

Whether you’re a seasoned diver or simply curious about the sea, there’s a place for you. You’ll leave with knowledge no travel guide gives, and often, you’ll come back the following year.
