Control on rate and pathway of anaerobic organic carbon degradation in the seabed
The degradation of organic matter in the anoxic seabed proceeds through a complex
microbial network in which the terminal steps are dominated by oxidation with sulfate or …

Extreme methane clumped isotopologue bio-signatures of aerobic and anaerobic methanotrophy: Insights from the Lake Pavin and the Black Sea sediments
Microbial methane oxidation-or methanotrophy-is a key control of the global methane
budget on Earth, and perhaps in other planetary systems. Here, we explore the potential role …

Erosion of carbonate-bearing sedimentary rocks may close the alkalinity budget of the Baltic Sea and support atmospheric CO2 uptake in coastal seas
High alkalinity values observed in coastal seas promote the uptake of CO2 from the
atmosphere. However, the alkalinity budget of coastal areas and marginal seas is poorly …

Physiological limits to life in anoxic subseafloor sediment
In subseafloor sediment, microbial cell densities exponentially decrease with depth into the
fermentation zone. Here, we address the classical question of'why are cells dying faster than …
