Record #80220:

Dating ice-wedge growth in subarctic peatlands following deforestation / Serge Payette, Line Gauthier, Ivan Grenier.

Title: Dating ice-wedge growth in subarctic peatlands following deforestation / Serge Payette, Line Gauthier, Ivan Grenier.
Author(s): Payette, Serge.
Gauthier, Line.
Grenier, Ivan.
Date: 1986.
In: Nature. (1986.), Vol. 322(6081) (1986)
Abstract: Combination of macrofossil peat stratigraphy and radiocarbon dating used to study development of ice wedges in sub-Arctic Quebec (56°N). Shows that inception and spatial development may occur after natural removal of coniferous vegetation, which induces snow-free conditions, permafrost aggradation and, ultimately, deep frost cracking. Ice wedges were dated indirectly, using combined rates of spruce removal and ice-wedge growth.
Notes:

Nature. Vol. 322(6081) :724-727 (1986).

Keywords: 551.345.3 -- Permafrost, composition and structure. Ice wedges.
E8 -- Glaciology: frost action and permafrost.
(*41) -- Canada.
(*424) -- Quebec.
