The 21st International Sedimentological Congress (the 21st ISC) will be held fully online from August 22–26, 2022. All the sessions will be live streamed throughout the conference. We sincerely invite you to register for the conference and submit abstracts to Session T4-1: Deep Biosphere: roles of subsurface life in elemental cycles and life-environment co-evolution.

 Session T4-1: Deep Biosphere: roles of subsurface life in elemental cycles and life-environment co-evolution

    Life persists and thrives in the subsurface of the Earth, in the complete absence of surface light energy. More than 50 years of investigations of this “deep biosphere” have revolutionized our understanding of Earth’s deepest ecosystems and biogeochemical elemental cycles, as well as the origin of life and its co-evolution with the environment. Still, large research gaps remain, e.g. what are the strategies for long-term survival of deep life on geological time scales? What are the fundamental mechanisms of the functioning of deep life and its evolution in low-energy subsurface environments? What role does deep life play in Earth’s geochemical cycles, across varying time scales? In this session, we would like to create a forum for recent exciting results in the deep-biosphere: from diversity and function to elemental cycling. We welcome papers studying life in both terrestrial and oceanic subsurface environments, and encourage studies on geochemical activities of deep life, the origin and evolution of deep life, and using new analytical techniques, that bridge various time scales, and that will enhance exploration of deep-biosphere frontiers.

The deadline for abstract submission is postponed to May 1, 2022.
