This was the ocean? Looked more like a bay or backyard pool with 1/4" ripples, but then again, I'm used to routine double overheads.
During the course of the 11/2 hour-long uphill, downhill, up the stairs and down the stairs tour the guide defensively explained of course this was not a failed experiment, no way whatsoever! However, I believe that by the early 1990s scientific methods were well established with concepts of controls and common sense solidly in place.
The people who lived on site (all scientists, carefully selected for their specialties) originally contracted for 5-year terms but due to failing mental and physical health along with many of the originally imported plants and all the animals dying they quit at the 21/2-year point. Rumor has it although they were supposed to find and prepare all their own meals, that wasn't possible with the scant resources available in the limited arrangement and for the final 6 months tasty, nutritious meals were brought in for them from a high-end establishment. Basic biosphere2 specs include:
- 3.14 acre Biosphere facility
- 7,200,000 cubic feet of sealed glass, 6,500 windows
- 91 feet at highest point
- sealed from the earth below by a 500-ton welded stainless steel liner
- 40-acre campus
- 300,000 sq. ft. of administrative offices, classrooms, labs, conference center, housing
- 3620' elevation (info from the website)
Who administers this facility? Since June 2007 Biosphere 2 has functioned as a department of the University of Arizona College of Science; they're trying to use it to help quantify some aspects of climate change.
The tropical rainforest is my last pic.
