Record #155275:

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.
