This study identifies cryptic methane cycling in coastal wetland sediments through geochemical and molecular analyses, showing methanogenesis and anaerobic methane oxidation co-occur with sulfate and iron reduction.

This study examines microbial communities in carbonate nodules and surrounding sediments within and below the sulfate-methane transition zone, revealing active endolithic microbes and their physiological responses to geochemical conditions.
