Measurements of dissolved methane in the ocean have been available for only about 50
years. Methane measurements in sediments, where concentrations are millimolar, were first …

The behaviour of the iconic ichnogenus Chondrites is re-evaluated based on review of
existing literature and analysis of novel data (macroscopic, thin section and ESEM-EDX …

Seabed fluid flow involves the flow of gases and liquids through the seabed. Such fluids
have been found to leak through the seabed into the marine environment in seas and …

Methane frozen into hydrate makes up a large reservoir of potentially volatile carbon below
the sea floor and associated with permafrost soils. This reservoir intuitively seems …

The short-chain hydrocarbons ethane, propane and butane are constituents of natural gas.
They are usually assumed to be of thermochemical origin, but biological formation of ethane …

Gulf of Mexico cold seeps characterized by variable compositions and magnitudes of
hydrocarbon seepage were sampled in order to investigate the effects of natural oils …

Sediments overlying a brine pool methane seep in the Gulf of Mexico (Green Canyon 205)
were analyzed using molecular and geochemical approaches to identify geochemical …

The anaerobic oxidation of methane in aquatic environments is a globally significant sink for
a potent greenhouse gas. Significant gaps remain in our understanding of the anaerobic …

Marine gas and hydrocarbon seeps are hot spots of sulfate reduction which is fuelled by
methane, other short‐chain alkanes or a complex mixture of hydrocarbons. In this study, we …

In seafloor sediments, the anaerobic oxidation of methane (AOM) consumes most of the
methane formed in anoxic layers, preventing this greenhouse gas from reaching the water …
