Experience Biosphere 2

Biosphere 2 Landscape Evolution Observatory (LEO) Tour

Take advantage of this rare and special opportunity to explore the world’s largest controlled research facility focused on understanding how our planet works. 

Biosphere 2 Landscape Evolution Observatory (LEO) Tour

Join a Biosphere 2 scientist for a behind-the-scenes-tour of our flagship Earth Science project. On this unique guided visit, guests will have an up-close look at the inner workings of the multi-million dollar Landscape Evolution Observatory (LEO) experiment. Your group can experience the LEO science project through the eyes and mind of a LEO scientist to get an in-depth introduction to this massive scale eco-hydrology and soil evolution experiment.

On the LEO Tour you will:
  • Hear about the many research uses of the enclosed LEO space over the past 25 years.
  • See the former Intensive Agriculture Biome and site of a carbon tree-physiology experiment.
  • Understand why control and scale are important for LEO and other Biosphere 2 science.
  • Learn about the engineering, design, construction, and instrumentation of the LEO experiment.
  • See the large hillslope research landscapes from above and below.
  • Tour the Stable Isotope Lab and learn how we use isotopes in LEO to track water as it moves through our study landscapes.
  • Use LEO sensors to learn how they (1,800 buried in each of three giant hillslopes!) measure CO2, Soil Moisture, Photosynthetic Active Radiation, etc.
  • Understand how electricity can be a useful tool in hydrology research (mini-LEO demonstration).
  • Learn about the value, and challenges, of an experiment at such a large scale.
  • Hear stories from the scientists themselves.
