Biosphere 2 (B2)
The Biosphere 2 facility (Earth is Biosphere 1), affectionately known as B2, was originally established to examine ecosystem cycling to support self-sustaining human life and research activities. The highly public experiments sealing humans inside for extended periods concluded in the mid-1990s. Since then, the facility has been further developed as a research facility now owned by the University of Arizona (UA) which uses the unique environmental control and monitoring systems to conduct large-scale projects. Situated at an elevation of 3,820 ft. in the desert northwest of Tucson, Arizona, B2 houses biomes including a coral reef, mangrove wetlands, tropical rainforest, savannah grassland, and fog desert (interactive aerial view). The Landscape Evolution Observatory (LEO) consists of three huge landscapes inside an environmentally controlled green house. LEO is used to investigate how water, carbon, and energy move through terrestrial landscapes.
Research Opportunities at B2
With the recent completion of LEO and ongoing development of the facility, B2 is a very active research site in the summer. In addition to research, the site hosts nearly 100K visitors per year and numerous REU, teacher development, and experiential education programs. STAR Fellows may or may not be offered a placement for any particular project. UA provides, at a cost, on-site housing for STAR Fellows offered a placement. Shared accommodations in the casitas are the most financially practical arrangement. Access to a personal vehicle is recommended for off-site travel, but is not necessary as the facility has regular shuttles to the nearest grocery stores. B2 provides extensive information on their website to help you prepare for local conditions. Many research projects involve extended periods of time in challenging environments inside and outside. The STAR Program welcomes B2 as a lab partner for the first time in summer 2015!
