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

In seafloor sediments, the anaerobic oxidation of methane (AOM) consumes most of the
methane formed in anoxic layers, preventing this greenhouse gas from reaching the water …

The Guaymas Basin in the Gulf of California is characterized by active seafloor spreading,
the rapid deposition of organic-rich sediments, steep geothermal gradients, and abundant …

Guaymas Basin is a young marginal rift basin in the Gulf of California characterized by active
seafloor spreading, rapid deposition of organic-rich sediments, and steep geothermal …

ABSTRACT The Guaymas Basin in the Gulf of California is characterized by active seafloor
spreading, hydrothermal activity, and organic matter accumulation on the seafloor due to …

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

Marine sediments are one of the largest organic carbon (OC) sinks on Earth. Yet, major
knowledge gaps remain in our understanding of sedimentary OC cycling, particularly …

Hydrocarbons are degraded by specialized types of bacteria, archaea, and fungi. Their
occurrence in marine hydrocarbon seeps and sediments prompted a study of their role and …

Hydrothermal sediments host phylogenetically diverse and physiologically complex
microbial communities. Previous studies of microbial community structure in hydrothermal …
