Deep Biosphere

Deep biosphere studies at USC principally focus on life in rock and sediments deep below the floor of the ocean, where it is estimated that 1/3 of the biomass on Earth is buried. Studies focus on understanding the activity in the deep biosphere: function & rates of global biogeochemical processes; understanding the extent of life: biomes and the degree of connectivity (biogeography & dispersal); determinations on the limits of life: extremes and norms of carbon, energy, nutrient, temperature, pressure, pH; and on evolution and survival: adaptation, enrichment, selection, and repair.
