Thermally induced movements in ice-wedge polygons, western Arctic coast: a long-term study / J. Ross Mackay.
Title: | Thermally induced movements in ice-wedge polygons, western Arctic coast: a long-term study / J. Ross Mackay. |
Author(s): | Mackay, J. Ross. |
Date: | 2000. |
In: | Géographie Physique et Quaternaire. (2000.), Vol. 54(1) (2000) |
Abstract: | Summary and figure captions in French. Summary in German. Extensive observations of ice-wedge polygons at three centres along western Arctic coast between 1965-95, show that thermal contraction (inward) is limited at polygon centres in winter, but expansion in summer is into ice-wedge troughs, allowing some transport of material. Discusses geomorphic, stratigraphic and palaeoclimatic implications of this movement. |
Notes: | Géographie Physique et Quaternaire. Vol. 54(1) :41-68 (2000). |
Keywords: | 551.34 -- Geocryology. Frozen ground. 551.343.2 -- Cryoturbation and patterned ground. E8 -- Glaciology: frost action and permafrost. (*41) -- Canada. (*411) -- Canadian Western Arctic. |
