SimBio2 is a simulation of Biosphere 2, the huge glass chamber constructed in Arizona to enable scientists to study the ecology of the earth (Biosphere 1). From 1991 until 1993 this nearly closed system supported people, plants, and animals. Experiments offered the opportunity for tracking in great detail the interactions among land and water ecosystems and the atmosphere.
SimBio2 offers several scenarios in which students can generate simulation graphs using actual data from the Biosphere 2 experiment. Students can explore some of the problems that affected Biosphere 2 such as higher levels of carbon dioxide than expected and the resulting decrease oxygen. Students can also create their own models and experiment with alternative strategies.
EarthSys - A Minimodel of Earth Metabolic Processes
EarthSys is a whole-earth (Biosphere 1) simulation similar to SimBio2. This minimodel of earth’s metabolism in the thin outer geobiosphere includes photosynthetic production, input of fossil fuels, and consumption by nature and the human urban civilization. Users can explore carbon dioxide accumulation, global warming, the impact of the increasing use of fossil fuels, and the role of the ocean carbonate sink.
