TL;DR: Under conventional growth conditions, the isotope fractionation of methanogenesis by M. kandleri strain 116 was similar to values previously reported for other hydrogenotrophic methanogens, but under high hydrostatic pressures, the atom fractionation effect became much smaller, and the kinetic isotope effect was one of the smallest effects ever reported.

TL;DR: Geochemical and microbiological evidence suggests that a HyperSLiME, consisting of methanogens and fermenters, occurs in this tectonically active subsurface zone, strongly supporting the existence of hydrogen-driven subsurfaced microbial communities.

TL;DR: Analysis of ground water issuing from two wells located near the epicenter of the Kobe earthquake in Japan shows precursory changes in chemical composition may reflect the preparation stage of a large earthquake.

TL;DR: The eGEOTRACES Electronic Atlas is the visual representation of the IDP2014 data providing section plots and a new kind of animated 3D scenes that provide geographical and bathymetric context that is crucial for the interpretation and assessment of observed tracer plumes.

TL;DR: A biogeochemical and microbiological characterization of a microbial community inhabiting deep-sea sediments overlying a natural CO2 lake at the Yonaguni Knoll IV hydrothermal field, southern Okinawa Trough suggests that microorganisms assimilatingCO2 and/or CH4 dominate the liquid CO2 and CO2-hydrate-bearing sediments.
