Changes in ice volume control seabed methane emissions

Ice sheet dynamics of the past likely caused fault movements in the Earth's crust, resulting in seabed methane release in ~1200 m water depth offshore Svalbard, an archipelago in the Norwegian Arctic.

Video: Burning ice from the ocean floor

Methane hydrate is a crystalline complex of water and methane that forms beneath the ocean floor. It resembles regular ice, but it can easily be set aflame after it's brought to the surface.

Wandering greenhouse gas

On the seafloor of the shallow coastal regions north of Siberia, microorganisms produce methane when they break down plant remains. If this greenhouse gas finds its way into the water, it can also become trapped in the sea ...
