Presentation Transcript

  1. DUSEL Science Questions • Dark Life (Biology) • How do biology and geology interact to shape the world underground? • How does subsurface microbial life evolve in isolation? • Did life on earth originate beneath the surface? • How deep does life go? Is there life not as we know it? • Restless Earth (Geosciences) • What controls flow and transport in deep subsurface? • What are key mechanisms of deformation? • Can we predict earthquakes? • How does complexity affect key processes? • Ground Truth (Geoengineering) • What lies between boreholes? • How can technology lead to a safer underground? • How can we optimize recovery of earth resources?
