Dempster, director of system engineering, and Norberto Alvarez-Romo, vice president of mission control. Project funding came primarily from the joint venture's financial partner, Ed Bass 's Decisions Investment. Location[ edit ] Biosphere 2 sits on a sprawling acre hectare science campus that is open to the public Exterior showing parts of the rainforest biome and of the habitat, with the West lung in the background.

The glass and spaceframe facility is located in Oracle, Arizona at the base of the Santa Catalina Mountainsabout 50 minutes north of Tucson. The fog desert section of Biosphere in The tropical rainforest biome in February, The above-ground physical structure of Biosphere 2 was made of steel tubing and high-performance glass and steel frames.

The frame and glazing materials were designed and made to specification by a firm run by a one-time associate of Buckminster FullerPeter Jon Pearce Pearce Structures, Inc. To avoid having to deal with the huge forces that maintaining a constant volume would create, the structure had large diaphragms kept in domes called "lungs" or variable volume structures.

Though cooling was the largest energy need, heating had to be supplied in the winter and closed loop pipes and air handlers were key parts of the energy system. An energy center on site provided electricity and heated and cooled water, employing natural gas and backup generators, ammonia chillers and water cooling towers.

Especially during the first year the eight inhabitants reported continual hunger. Calculations indicated that Biosphere 2's farm was amongst the highest producing in the world "exceeding by more than five times that of the most efficient agrarian communities of Indonesia, southern China, and Bangladesh.

They showed the same improvement in health indices such as lowering of blood cholesterol, blood pressure, enhancement of immune system. The fog desert area became more chaparral in character due to condensation from the space frame. The savannah was seasonally active; its biomass was cut and stored by the crew as part of their management of carbon dioxide.

Rainforest pioneer species grew rapidly, but trees there and in the savannah suffered from etiolation and weakness caused by lack of stress woodnormally created in response to winds in natural conditions. Corals reproduced in the ocean area, and crew helped maintain ocean system health by hand-harvesting algae from the corals, manipulating calcium carbonate and pH levels to prevent the ocean becoming too acidic, and by installing an improved protein skimmer to supplement the algae turf scrubber system originally installed to remove excess nutrients.

Many insects had been included in original species mixes in the biomes but a globally invasive tramp ant species, Paratrechina longicornisunintentionally sealed in, had come to dominate other ant species.

The crew's kitchen as it originally looked during the first mission.

Much of the evidence for isolated human groups comes from psychological studies of scientists overwintering in Antarctic research stations. This is in contrast to other expeditions where internal frictions can lead to unconscious sabotage of each other and the overall mission.

All of the crew felt a very strong and visceral bond with their living world. That was the nature of the factionalism The faction that included Poynter felt strongly that increasing research should be prioritized over degree of closure.

The other faction backed project management and the overall mission objectives. A majority of the SAC members chose to remain as consultants to Biosphere 2.

Some sixty-four projects were included in the research program that Walford and Alling spearheaded developing.ARCHIVES and KNOWLEDGE MANAGEMENT Scholarly online resource evidence and records for use by genealogists and family historians.
