MYSTÈRES DES OCÉANS

Dive beneath the surface. Discover a world you never suspected.

🌊 Start the dive

Surface

0 m

Sunlight floods the water. This is where every dive begins.

Sunlight zone

10 m

Still plenty of light, but warm colours (red, orange) are already starting to fade.

First great depths

50 m

Reefs, kelp forests: the most densely populated realm of the ocean.

Twilight zone

100 m

Light fades fast. Some organisms are starting to make their own.

Entering the dark world

200 m

The edge of the sunlit zone. Beyond this point, photosynthesis becomes impossible.

The deep

500 m

Near-total darkness. Bioluminescence becomes the main visual language.

Entering the midnight zone

1000 m

No sunlight reaches this far down anymore. The dive continues, far deeper still.

The heart of the bathypelagic zone

2000 m

Total darkness for a long time now. The species living here either make their own light or do entirely without it.

The abyssopelagic zone

4000 m

The abyssal plains begin here. In 1977, near the Galápagos, the discovery of hydrothermal vents at this depth upended biology.

Entering the hadal zone

6000 m

The least explored realm on the planet. This is where the ocean trenches begin.

The first great trenches

8000 m

Some ocean trenches already reach this depth, well before the deepest point known.

The Mariana Trench

11000 m

The deepest known point in the oceans (Mariana Trench). Crushing pressure, over 1,000 times that of the surface — and yet life still exists here.
