Oxygen at Biosphere 2

Here is a photo of part of the Biosphere 2 Structures.

During the two year mission when the eight member crew was sealed into the structure, oxygen did deteriorate.

Oxygen began at 20.9%, but over 16 months fell to 14.5%.

This is the equivalent of oxygen at about 4,000 meters (13,000 feet).

Some of the biospherians were starting to have symptons of oxygen deprivation such as sleep apnea and fatigue. The outside medical team decided to make two injections of oxygen into the structure during the last few months of the two year mission.

Interesting story. I guess they couldn't leave the volunteers to die of oxygen deprivation. There might be some objections to that!

Another excellent shot, another excellent fact! Thank you so much for this, Julie.

If I'm not mistaken, that round building was called "the Lungs" of the structure, pushing what little oxygen there was throughout the whole bulding.

Fascinating facts. I have not been to the Biosphere 2 in more than 15 years. Your series is both informative and the photos are excellent.

Interesting read, and some nice photos from the Biosphere.

As a cloud geek I'm as attracted by the clouds in your shot as by the architecture.
