HADAL
The ocean keeps its history at the bottom.
We go down to read it — one instrumented descent at a time.
Begin the descent200 – 1,000 m · Twilight zone
Light thins. Life adapts.
Two hundred metres down, the last daylight gives out. What remains falls as marine snow — a slow, constant drift of everything the surface let go — and our sensor chains ride it all the way down.
1,000 – 4,000 m · Midnight zone
Down here, everything makes its own light.
Nothing in this water has ever seen the sun. Life writes its own constellations instead, and HADAL's dark-adapted arrays have spent nine years learning to read them.
10,911 m · Hadal zone · Station Meridian
The deepest habitat humans have ever kept.
Nine crew. Twelve months of dark. Every descent adds a page to the ocean's oldest record.
