About this Research Topic
An effort to consolidate up to date research concerning the terrestrial deep biosphere is of critical importance as rates of primary production, energy flux, and elemental cycling in the deep biosphere are still virtual unknowns. Further, the connectivity between surface processes and deep biosphere processes may include the seeding of surface environments with “legacy” subsurface genetic material. This Research Topic will address these issues, focusing on evidence and implications of connection between the geosphere, hydrosphere, and biosphere of terrestrial deep subsurface habitats.
