Methane seeps are widespread seafloor ecosystems shaped by the emission of gas from
seabed reservoirs. The microorganisms inhabiting methane seeps transform the chemical …

Methyl‐coenzyme M reductase (MCR) has been originally identified to catalyse the final
step of the methanogenesis pathway. About 20 years ago anaerobic methane‐oxidizing …

Expansion of shale gas extraction has fuelled global concern about the potential impact of
fugitive methane on groundwater and climate. Although methane leakage from wells is well …

Emission of the greenhouse gas methane from the seabed is globally controlled by marine
aerobic and anaerobic methanotrophs gaining energy via methane oxidation. However, the …

In marine sediments the anaerobic oxidation of methane with sulfate as electron acceptor (AOM)
is responsible for the removal of a major part of the greenhouse gas methane. AOM is …

The methane-emitting cold seeps of Hikurangi margin (New Zealand) are among the few
deep-sea chemosynthetic ecosystems of the Southern Hemisphere known to date. Here we …

Around 50% of humankind relies on groundwater as a source of drinking water. Here we
investigate the age, geochemistry, and microbiology of 138 groundwater samples from 95 …

Phytoplankton blooms in surface waters of the oceans are known to influence the food web
and impact microbial as well as zooplankton communities. Numerous studies have …

Marine cold seeps are unique chemosynthetic habitats fuelled by deeply sourced
hydrocarbon‐rich fluids discharged at the seafloor. Through oxidizing methane and other …

The hydrothermal sediments of Guaymas Basin, an active spreading center in the Gulf of
California (Mexico), are rich in porewater methane, short-chain alkanes, sulfate and sulfide, …
