Organic carbon in marine sediments is a critical component of the global carbon cycle, and
its degradation influences a wide range of phenomena, including the magnitude of carbon …

The warming of the Arctic Ocean impacts the dissolved organic matter (DOM) imports into
the Arctic region, which affects the local bacterial communities. This review addressed the …

Analyses of gene expression of subsurface bacteria and archaea provide insights into their
physiological adaptations to in situ subsurface conditions. We examined patterns of …

Cold seeps and hydrothermal vents are seafloor habitats fueled by subsurface energy
sources. Both habitat types coexist in Guaymas Basin in the Gulf of California, providing an …

The flanking regions of Guaymas Basin, a young marginal rift basin located in the Gulf of
California, are covered with thick sediment layers that are hydrothermally altered due to …

While the biogeochemical forces influencing the weathering of spilled oil have been
investigated for decades, the environmental fate and effects of “oxyhydrocarbons” in sand …

Temperature and bioavailable energy control the distribution of life on Earth, and interact
with each other due to the dependency of biological energy requirements on temperature …

Deep-sea hydrothermal vents are unique ecosystems that may release chemically distinct
dissolved organic matter to the deep ocean. Here, we describe the composition and …

Abstract In Guaymas Basin, organic-rich hydrothermal sediments produce complex
hydrocarbon mixtures including saturated, aromatic and alkylated aromatic compounds. We …

Volatile fatty acids (VFAs) and alcohols are key intermediates of anaerobic carbon
metabolism, yet their biogeochemical cycling remains poorly constrained in hydrothermal …
