Methane flux from boreal peat-lands
Crill P., Bartlett K., Roulet N. Methane flux from boreal peat-lands.
Tiivistelmä
The peatlands found in the boreal zone (roughly 45°-60°N) store a significant reservoir of carbon, much of which is potentially available for exchange with the atmosphere. The anaerobic conditions that cause these soils to accumulate carbon also makes wet, boreal peatlands significant sources of methane (CH4) to the global troposphere. We estimate that boreal wetlands contribute approximately 19.5 Tg CH4 yr-1. The data available on the magnitude of boreal CH4 emissions have rapidly accumulated in the past twenty years. This paper offers a short review of the flux measurements (which range from roughly I to 2 000 mg CH4 m-2 d-1'), considers environmental controls of the flux and briefly discusses how climate change might affect future fluxes.
