Doomsday Vault for plant seeds

Consutruction began today on the Svalbard International Seed Vault, or "doomsday vault," an arctic mountain cache to protect three million seed samples in the event of a global catastrophe. Under construction six hundred miles from the North Pole, the $4.8 million vault is being funded by Norway and will be co-run by the independent Global Crop Diversity Trust. It's slated to open in September 2007. From the Associated Press:

Its purpose is to ensure the survival of crop diversity in the event of plant epidemics, nuclear war, natural disasters or climate change, and to offer the world a chance to restart growth of food crops that may have been wiped out.

The seeds, packaged in foil, would be stored at such cold temperatures that they could last hundreds, even thousands, of years, according to the independent Global Crop Diversity Trust…

The Svalbard Archipelago, 300 miles north of the mainland, was selected because it is located far from many threats and has a consistently cold climate.

Those factors will help protect the seeds and safeguard their genetic makeup, Norway's Foreign Ministry said. The vault will have thick concrete walls, and even if all cooling systems fail, the temperature in the frozen mountain will never rise above freezing due to permafrost, it said.

While the facility will be fenced in and guarded, Svalbard's free-roaming polar bears, known for their ferocity, could also act as natural guardians, according to the Global Diversity Trust.

"This facility will provide a practical means to re-establish crops obliterated by major disasters," Cary Fowler, the trust's executive secretary, said in a statement, adding that crop diversity is also threatened by "accidents, mismanagement and shortsighted budget cuts."
