Abstract The Vestnesa Ridge is a NW-SE trending,~ 100 km-long, 1–2 km-thick contourite
sediment section located in the Arctic Ocean, west of Svalbard, at 79° N. Pockmarks align …

Terra Nova, 24, 255–272, 2012 Abstract Cold seep systems comprise three structural
elements: source, plumbing system, and venting structures or see** features at or near the …

Pockmarks are normally regarded to be manifestations of fluids escape through the seabed.
Kilometer-wide depressions, here called mega-pockmarks occur as widespread features …

Fracture-filling hydrates were recovered above the gas chimneys originating from the
Songnan Low Uplift in the northern Qiongdongnan Basin, South China Sea. The variable …

Gas and gas hydrates have gained considerable attention in the last 20yr due to their
possible impact on global climate change from methane escalations. Our study area, the SW …

In response to the accelerating processes of marine natural gas hydrate exploration and gas
production from hydrate-bearing sediments, their potential impacts on the environment have …

The active Haima cold seep sites were discovered by the remotely operated vehicle on the
western part of the northern slope of South China Sea in 2015 and 2016. However, the …

Cold-seep benthic communities in the Arctic exist at the nexus of two extreme environments;
one reflecting the harsh physical extremes of the Arctic environment and another reflecting …

Polycyclic aromatic hydrocarbons (PAH) were measured in sediment cores from 13
locations in South-Western Barents Sea as part of a detailed study of the Norwegian seabed …

The processes preceding the genesis of pockmarks and their subsequent evolution has
been rarely studied since pockmarks were discovered in 1970. A high-resolution 3-D …
