Glacier
Archivethe seed vault inside the ice

One hundred and thirty metres inside a frozen Arctic mountain, we hold a backup copy of agriculture itself — 1.26 million seed samples, sealed in permafrost that has not thawed in twelve thousand years.

01 — The vault inside the ice

A room built to be forgotten, and never lost.

Every seed bank on Earth is fragile. War, blackouts, funding cuts, a failed freezer on a Tuesday — any of them can erase a lineage bred over ten thousand harvests. Glacier Archive exists so that loss is never final.

We are not a working collection. Nobody withdraws seed to plant. We are the copy of last resort — a black box for the planet's food crops, opened only when a national gene bank has lost the original. In our first fifteen years that has happened exactly once, when the seed banks of Aleppo were evacuated under fire and rebuilt, grain by grain, from boxes we had kept frozen in the dark.

The mountain does the work. Even if every mechanical chiller failed and the doors were sealed for a century, the surrounding permafrost would hold the chambers below −4°C indefinitely. The cold here is not a service we provide. It is a property of the place.

03 — Cold science

Why minus eighteen?

Cold does not preserve a seed by pausing time. It preserves by slowing the chemistry of decay until a lifespan is measured in centuries instead of seasons.

−18°

The international standard

At −18°C a dry seed's metabolism nearly stalls. Genebanks worldwide agreed on this figure because below it, longevity gains flatten while energy costs climb. It is the knee of the curve.

5%

Moisture is the enemy

Before freezing, every accession is dried to roughly 5% internal moisture. Water is what lets ice crystals rupture cell walls; a dry seed can be frozen hard and revived decades later, intact.

Every 5°C down doubles life

The Ellis–Roberts rule: for many species each 5°C drop roughly doubles storage life. From a warm room to our chambers is the difference between a decade and a millennium.

04 — Depositors

Seed still belongs to the sender.

Under the deposit agreement, we hold — we never own. Boxes remain the sealed property of the depositing nation or institution, retrievable only by them. These are among the trust's largest partners.

05 — Visit & contact

The vault is closed. The archive is not.

For its own protection, the mountain opens only three times a year, for scheduled deposits. There are no public tours — the cold is the point. But researchers, depositing bodies and the merely curious can reach us here.
