(Phys.org) —A small team of researchers in the U.S. has discovered the presence of 570 bubble plumes along the Atlantic coast of the U.S. between North Carolina and Massachusetts—the plumes are believed to be methane ...
Iron and manganese compounds, in addition to sulfate, may play an important role in converting methane to carbon dioxide and eventually carbonates in the Earth's oceans, according to a team of researchers looking at anaerobic ...

Large amounts of methane - whether as free gas or as solid gas hydrates - can be found in the sea floor along the ocean shores. When the hydrates dissolve or when the gas finds pathways in the sea floor to ascend, the methane ...

Methane hydrates are fragile. At the sea floor the ice-like solid fuel composed of water and methane is only stable at high pressure and low temperature. In some areas, for instance in the North Atlantic off the coast of ...

On the continental margins, where the seafloor drops hundreds of meters below the water's surface, low temperatures and high pressure lock methane inside ice crystals. Called methane hydrates, these crystals are a potential ...
