Welcome to Svalbard

Svalbard is a Norwegian archipelago located about 746 miles (1,200 kilometers) from the North Pole. The island is known for its frozen tundra, snowy landscapes and dramatic glaciers.

The vault was designed to protect all of the world's important crop seeds in case of a man-made or natural disaster. Here, Aasmund Asdal, coordinator of the Nordic Genetic Resource Centre, carries crates of seeds from Japan and the United States into the seed vault in Svalbard.

To access the seed vault, visitors must pass through four locked doors: the heavy steel entrance doors, a second door approximately 380 feet (115 meters) down the tunnel and finally the two keyed air-locked doors. Here's a view down the entrance tunnel toward the offices and storage chambers in the Svalbard Global Seed Vault.

The secure vault has a capacity to hold 4.5 million grains. It currently stores seeds from cultures all over the world in an effort to preserve genetic diversity and defend against major food crises. The seed vault is housed about 430 feet (130 meters) below sea level, which guarantees that the seeds will remain dry even in the face of rising sea levels and melting glaciers.

Nice and cold

In the vault's main storage room, seeds are kept at minus 0.4 degrees Fahrenheit (minus 18 degrees Celsius).

Seed stocks

Boxes with seeds from around the world are saved for posterity in the Svalbard Global Seed Vault. The vault can hold 4.5 million seed samples — and since each sample contains about 500 seeds, a maximum of 2.25 billion seeds will fit into the vault.

Seed preservation

The seeds are kept in bags inside the vault. The arctic permafrost offers natural freezing for the seeds, but the vault also has additional cooling to keep temperatures at minus 0.4 degrees Fahrenheit (minus 18 degrees Celsius).
