Methane release from warming-induced hydrate dissociation in the West Svalbard continental margin: timing, rates, and geological controls [PDF]
, 2013 Hundreds of plumes of methane bubbles, first observed in 2008, emanate from an area of the seabed off West Svalbard that has become 1°C warmer over the past 30 years. The distribution of the plumes, lying close to and upslope from the present upper limit

Consumption of Methane by Soils [PDF]
Environmental Monitoring and Assessment, 1994 Measurements of the methane flux and methane concentration profiles in soil air are presented. The flux of methane from the soil is calculated by two methods: a) Direct by placing a static open chamber at the soil surface. b) Indirect, using the (222)Rn concentrations profile and the (222)Rn flux in the soil surface in parallel with the methane ...
