Fluid flow related seafloor structures and gas seeps were detected in the North Sea in the
1970s and 1980s by acoustic sub-bottom profiling and oil rig surveys. A variety of features …

Seabed hydrocarbon seeps present natural laboratories for investigating responses of
marine ecosystems to petroleum input. A hydrocarbon seep near Scott Inlet, Baffin Bay, was …

The anoxic layers of marine sediments are dominated by sulfate reduction and
methanogenesis as the main terminal oxidation processes. The aim of this study was to …

A site at the gas hydrate stability limit was investigated offshore northwestern Svalbard to
study methane transport in sediment. The site was characterized by chemosynthetic …

Methane seepages are widespread in the Black Sea. However, microbiological research
has been carried out only at the continental shelf seeps. The present work dealt with coastal …

A combination of physicochemical and radiotracer analysis, high-throughput sequencing of
the 16S rRNA, and particulate methane monooxygenase subunit A (pmoA) genes was used …

Sediment cores from the REGAB pockmark, an active cold seep area in the southeast
Atlantic, were analysed for their lipid biomarker distribution and associated stable carbon …

Cold seep environments such as sediments above outcropping hydrate at Hydrate Ridge
(Cascadia margin off Oregon) are characterized by methane venting, high sulfide fluxes …

Cold seeps are characterized by high biomass, which is supported by the microbial
oxidation of the available methane by capable microorganisms. The carbon is subsequently …

Methane is a powerful greenhouse gas but the microbial diversity mediating methylotrophic
methanogenesis is not well‐characterized. One overlooked route to methane is via the …
