Metagenomic and geochemical characterization of pockmarked sediments overlaying the Troll petroleum reservoir in the North Sea [PDF]
Background Pockmarks (depressions in the seabed) have been discovered throughout the world’s oceans and are often related to hydrocarbon seepage. Although high concentrations of pockmarks are present in the seabed overlaying the Troll oil

Gas Hydrate Occurrence Inferred from Dissolved Cl- Concentrations and delta O-18 Values of Pore Water and Dissolved Sulfate in the Shallow Sediments of the Pockmark Field in Southwestern Xisha Uplift, Northern South China Sea [PDF]
Deep-water pockmarks are frequently accompanied by the occurrence of massive gas hydrates in shallow sediments. A decline in pore-water Cl-concentration and rise in delta O-18 value provide compelling evidence for the gas hydrate dissociation.

Evidence for intense REE scavenging at cold seeps from the Niger Delta margin
International audienceFor many trace elements, continental margins are the location of intense exchange processes between sediment and seawater, which control their distribution in the water column, but have yet to be fully understood.

Fine-scale community structure analysis of ANME in Nyegga sediments with high and low methane flux
To obtain knowledge on how regional variations in methane seepage rates influence the stratification, abundance and diversity of anaerobic methanotrophs (ANME) we analyzed the vertical microbial stratification in a gravity core from a methane micro ...

BENTHIC FORAMINIFERA RESPONSE TO METHANE RELEASE INAN ADRIATIC SEA POCKMARK
The presence of methane-bearing shallow sediments in the Adriatic Sea has been known since the fifties, but little is known about the benthic foraminiferal assemblages associated with them.

Anomalous seafloor backscatter patterns in methane venting areas, Dnepr paleo-delta, NW Black Sea [PDF]
The relation between acoustic seafloor backscatter and seep distribution is examined by integrating multibeam backscatter data and seep locations detected by single-beam echosounder.
