This biogeochemical, molecular genetic and lipid biomarker study of sediments (∼ 4 m
cores) from the Skagerrak (Denmark) investigated methane cycling in a sediment with a …

The Tommeliten seepage area is part of the Greater Ekofisk area, which is situated above
the Tommeliten Delta salt diapir in the central North Sea (56° 29.90'N, 2° 59.80'E …

The organic rich sediments of the Skagerrak contain high quantities of shallow gas of mostly
biogenic origin that is transported to the sediment surface by diffusion. The sulfate methane …

Marine surface sediments, which are replete with sulfate, are typically considered to be
devoid of endogenous methanogenesis. Yet, methanogenic archaea are present in those …

The anaerobic oxidation of methane (AOM) is a major methane sink in marine sediments
and plays a crucial role in mitigating methane fluxes to the overlying water column. We …

Anaerobic methane oxidation was investigated in 6-m-long cores of marine sediment from
Aarhus Bay, Denmark. Measured concentration profiles for methane and sulfate, as well as …

Anaerobic methane‐oxidizing microbial communities in sediments at cold methane seeps
are important factors in controlling methane emission to the ocean and atmosphere. Here …

Methane seepages typically harbor communities of anaerobic methane oxidizers (ANME);
however, knowledge about fine-scale vertical variation of ANME in response to geochemical …

Benthic microbial methanogenesis is a known source of methane in marine systems. In most
sediments, the majority of methanogenesis is located below the sulfate-reducing zone, as …

Methylotrophic methanogenesis is often proposed to be responsible for methane production
in sulfate‐rich environments, yet the magnitude of this process remains elusive. In this study …
