The leakage of cold, methane-rich fluids from subsurface reservoirs to the sea floor at
specific sites on continental slopes, termed cold seeps, sustains some of the richest …

The accumulation of methane hydrate in marine sediments is controlled by a number of
physical and biogeochemical parameters including the thickness of the gas hydrate stability …

To date, several cold-seep areas which fuel chemosynthesis-based benthic communities
have been explored, mainly by deployment of manned submersibles. They are located in …

Cold seeps occur in geologically active and passive continental margins, where pore waters
enriched in methane are forced upward through the sediments by pressure gradients. The …

Hadal trenches account for the deepest 45% of the oceanic depth range and host active and
diverse biological communities. Advances in our understanding of hadal community …

Geological methane, generated by microbial decay and the thermogenic breakdown of
organic matter, migrates towards the surface (seabed) to be trapped in reservoirs …

Mixed methane–sulfide hydrates and carbonates are exposed as a pavement at the seafloor
along the crest of one of the accretionary ridges of the Cascadia convergent margin. Vent …

More than a dozen hydrocarbon seep‐carbonate occurrences in late Jurassic to late
Cretaceous forearc and accretionary prism strata, western California, accumulated in …

Extensive deposits of methane hydrate characterize Hydrate Ridge in the Cascadia margin
accretionary complex. The ridge has a northern peak at a depth of about 600 m, which is …

Analysis of three-dimensional seismic data and multibeam data from the Pearl River Mouth
Basin in the northern South China Sea, reveals numerous focused fluid flow features and …
