NSF Research Experiences for Undergraduates (REU)


The World's Largest Earth Science Experiment

Discover the world in a 3.14-acre laboratory with active research systems spanning from ocean to desert environments and so much more.

Dive into the Ocean

We’ve gone headfirst into revitalizing our ocean system to be a premier research space for coral reef restoration. Learn about the revitalization process that’s currently taking place.

Dive In

Take Shelter in the Rain Forest

We know that rain forest plants have a lot to tell us about the world’s ecosystem. We use this system to listen carefully and inform integral changes to adapt to climate change.


Discover the Desert

Our desert is uniquely set apart from the Sonoran desert that houses it. Designed to simulate an arid desert scrub ecosystem, the Biosphere 2 desert brings the coastal desert experience to you.

Get Lost Among the Mangroves

Take a trip to the tropics with our mangroves at Biosphere 2. This system allows us to look closely at two key types of wetlands and put plans to action for restoring these systems in the wild.

Uncover History in the Savanna

Explore the savanna and learn the history of how this system served as a hydrological transition zone designed to balance atmospheric chemistry between two uniquely different environments: the desert and the rain forest.
