MARC recordDating 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. |
