palsa bog

A Dictionary of Ecology | 2004 | | Copyright

palsa bog Boggy tundra, in which ground ice is partly responsible for the formation of peat hummocks up to 35 m long, 15 m wide, and 7 m high. Palsa bogs have a core of frozen peat and develop cyclically. The dark surface with pools of water provide insulation and prevent snow from lying, causing the bog to grow; it develops a cover of lichen, giving it a high albedo; it erodes as the surface becomes unstable; the erosion reveals peat, which is dark and reduces the albedo, causing the bog to warm, leading to melting; a pool forms and the sequence begins again. Palsa bogs are circumpolar in distribution and are apparently subfossil.
