Low Heat Flow in the Anhydros Basin, Aegean Sea, Recorded by Deep Subsurface Temperatures

open access: yesGeophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract Subseafloor in situ temperatures in a drilled hole in the Anhydros Basin, Aegean Sea, measured during International Ocean Discovery Program (IODP) Expedition 398, yielded a low heat flow (<0.023 W/m2) despite active magmatism and rifting in the region.

Genomic variation in microbial populations inhabiting the marine subseafloor at deep-sea hydrothermal vents

open access: yesNature Communications, 2017
The warm subseafloor at deep-sea hydrothermal vents hosts diverse microbial communities. Here, Anderson et al. reconstruct 73 metagenome-assembled genomes from two geochemically distinct hydrothermal vent fields, showing different patterns of genomic ...

Acetogenesis in the energy-starved deep biosphere – a paradox?

open access: yesFrontiers in Microbiology, 2012
Under anoxic conditions in sediments, acetogens are often thought to be outcompeted by microorganisms performing energetically more favorable metabolic pathways, such as sulfate reduction or methanogenesis. Recent evidence from deep subseafloor sediments

Weak hydrothermal carbonation of the Ongeluk volcanics: evidence for low CO2 concentrations in seawater and atmosphere during the Paleoproterozoic global glaciation

open access: yesProgress in Earth and Planetary Science, 2017
It was previously revealed that the total CO2 concentration in seawater decreased during the Late Archean. In this paper, to assess the secular change of total CO2 concentration in seawater, we focused on the Paleoproterozoic era when the Earth ...

Significant contribution of subseafloor microparticles to the global manganese budget

open access: yesNature Communications, 2019
Ferromanganese minerals are abundant in marine environments but the extent of these minerals in subseafloor sediments remains unknown. Here the authors find abundant ferromanganese microparticles in oxic pelagic clays, accounting for 14–16% of the new ...

Chromite oxidation by manganese oxides in subseafloor basalts and the presence of putative fossilized microorganisms

open access: yesGeochemical Transactions, 2011
Chromite is a mineral with low solubility and is thus resistant to dissolution. The exception is when manganese oxides are available, since they are the only known naturally occurring oxidants for chromite.

CO2 Geological Storage Using the Clathrate Hydrate

open access: yesJournal of MMIJ
Carbon dioxide capture and storage (CCS) is expected to be a key decarbonization technology for achieving carbon neutrality. Sensitivity analyses using an energy system model on CCS costs and storage capacity indicate that increasing domestic CO2 storage
