Large quantities of methane are stored in hydrates and permafrost within shallow marine
sediments in the Arctic Ocean. These reservoirs are highly sensitive to climate warming, but …

Hydrate Ridge, Cascadia convergent margin, is characterized by abundant methane
hydrates at and below the seafloor, active venting of fluids and gases, chemosynthetic …

Hydrate research has expanded substantially over the past decade, resulting in more than
4,000 hydrate-related publications. Collating this vast amount of information into one source …

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 …

There is growing concern about the transfer of methane originating from water bodies to the
atmosphere. Methane from sediments can reach the atmosphere directly via bubbles or …

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 …

Large uncertainties about the energy resource potential and role in global climate change of
gas hydrates result from uncertainty about how much hydrate is contained in marine …

The assessment of climate change factors includes a constraint of methane sources and
sinks. Although marine geological sources are recognized as significant, unfortunately, most …

At the summit of Hydrate Ridge (ODP Sites 1249 and 1250), pore fluids are highly enriched
in dissolved chloride (up to 1370 mM) in a zone that extends from near the sediment surface …

A mud volcano area in the deep waters (> 2000m) of the Black Sea was studied by
hydroacoustic measurements during several cruises between January 2002 and June 2004 …
