Abyssal Station Nine is a permanent research habitat on the floor of the Challenger Deep, the deepest surveyed point in any ocean. Sixty two people live and work there in the dark. This page is a dive: scroll, and we will take you down all 10,994 metres.

ZONE 01Epipelagic · 0 to 200 m
Where we leave the light.
Every rotation begins the same way: on the deck of RV Meridian, in weather, in noise, in the last natural light the crew will see for months. The submersible cradle swings out, the hatch seals, and the ocean accepts one more delivery.
The sunlight zone is thinner than most people imagine. Photosynthesis, weather, and nearly every fish you have ever eaten: all of it happens in a layer shallower than the station is long.
Temp 22.4 °C
Light 100%
Pressure 1 atm
Program 01
Surface Exchange
Continuous gas flux measurement between the sea surface and atmosphere above the trench, the longest unbroken record of its kind.
Program 02
Photic Census
An annual survey of everything that lives in the light, so we can measure exactly what the deep is missing.
ZONE 02Mesopelagic · 200 to 1,000 m
The first lie the ocean tells you is that it is empty.
Past two hundred metres, blue is the only colour that survives, and then barely. This is the twilight zone, home to the largest animal migration on Earth: every night, billions of tonnes of life rise toward the surface to feed, and sink again before dawn.
It is also where the ocean starts making its own light. Most animals down here can produce it. We are still learning what they are saying.
Move your cursor through the water. The plankton will answer.
Program 04
Photophore Grammar
A decade-long effort to decode bioluminescent signalling: which flashes mean courtship, which mean threat, and which mean nothing at all.
Program 05
Vertical Migration Array
Forty acoustic buoys tracking the nightly ascent of the deep scattering layer, the heartbeat of the water column.
ZONE 03Bathypelagic · 1,000 to 4,000 m
No sunlight has ever reached this water. Not once.
Below a thousand metres the ocean is permanently, perfectly dark. Temperature falls to four degrees and stays there. Food arrives as a slow snowfall of organic matter from the world above, and everything that lives here has learned to wait.
Our midnight moorings watch the fall of a single whale carcass for years at a time. A whale fall can feed a community for decades: first the flesh, then the bone, then the chemistry inside the bone.
Temp 4.0 °C
Light None
Pressure 10 to 40 MPa
Program 07
Whale Fall Observatory
Time-lapse ecology at Station M-3, now in year six of watching one skeleton become an ecosystem.
Program 08
Acoustic Cartography
Mapping the trench walls with sound, one ping at a time, at resolutions satellites will never reach.
ZONE 04Abyssopelagic · 4,000 to 6,000 m
A desert that is anything but empty.
The abyssal plains cover more than half the planet, and we have mapped less of them than the surface of Mars. Sediment here accumulates at a centimetre per thousand years. Step lightly: the seafloor remembers everything.

Home.
The hadal zone exists only in trenches: narrow scars where one tectonic plate slides beneath another. The pressure at the bottom exceeds 1,000 atmospheres, the weight of a small car pressing on every square centimetre. Life thrives here anyway, and so, carefully, do we.
Station Nine sits on a terrace above the trench axis: four habitat rings, two wet labs, a hangar, and the only permanent human address below six thousand metres.
"You do not conquer the trench. You are permitted to stay, one pressure check at a time."

D+3,204 · 06:12Hadal lander HL-2 recovered with intact amphipod colony from 10,920 m. Wet lab reports the samples are, in Ferreira's words, absurdly lively.
D+3,201 · 22:47Hydrophone lattice recorded a 9 minute low-frequency event of unknown origin, bearing 214. Filed for review. Third such event this rotation.
D+3,198 · 14:30Resupply pod from Meridian arrived on schedule. Fresh oranges in the mess for the first time in 41 days. Morale readings: elevated.
Expedition Twelve is assembling. The trench has room for you.
We accept twelve new crew per rotation: scientists, engineers, medics, and one cook who does not panic at 1,086 atmospheres. Applications close at the end of the season.

The bottom is not the end.
It is the frontier.
Abyssal Station Nine is a fictional institute, built as a study in depth,
pressure, and light.
The ocean below six thousand metres is real, and almost entirely unexplored.
