Methane Seeps Ocean Floor

Brine pools are commonly found below polar sea ice and in the deep ocean.
Methane seeps ocean floor. If we understand how nature reacts to these methane seeps at the sea floor it will help us to estimate the consequences of larger methane releases from gas hydrates. Instead of abrupt release of methane which is evident in other parts of the arctic the hydrate melt in ocean floor off western svalbard caused slow and steady seeps that are ongoing. The cold is relative to the very warm at. These seeps are a kind of natural model where the behaviour of methane in the ocean can be studied.
However even as researchers learn more about their role in sustaining a healthy earth these habitats are being threatened by a wide range of human. Cold does not mean that the temperature of the seepage is lower than that of the surrounding sea water. The hydrothermal vents and methane seeps on the ocean floor that were once thought to be geologic and biological oddities are now emerging as a major force in ocean ecosystems marine life and global climate. These pools are dense bodies of water that have a salinity three to eight times greater than the surrounding ocean.
The data obtained at the methane seeps should also help to improve the. The hydrothermal vents and methane seeps on the ocean floor that were once thought to be geologic and biological oddities are now emerging as a major force in ocean ecosystems marine life and. A cold seep sometimes called a cold vent is an area of the ocean floor where hydrogen sulfide methane and other hydrocarbon rich fluid seepage occurs often in the form of a brine pool. A brine pool is a volume of brine collected in a seafloor depression.

Clusters of microbes are seen on the bottom of the ocean floor in the ross sea indicating a methane seep as a crack in the ice above lets in light in antarctica in this handout photo taken in. The team behind the new findings studied what is termed the continental margin the region of the ocean floor that stands between the coast and the deep ocean.
