Record #117030:

A solifluction meter for permafrost sites / Antoni G. Lewkowicz.

Title: A solifluction meter for permafrost sites / Antoni G. Lewkowicz.
Author(s): Lewkowicz, Antoni G.
Date: 1992.
In: Permafrost and Periglacial Processes. (1992.), Vol. 3(1) (1992)
Abstract: Describes instrument that measures soil movements at eight levels in active layer. Anchored in permafrost, meter transforms mechanical movement of wooden blocks attached to flexible racks into changes in electrical resistance of potentiometers. Solifluction can be monitored continuously with data-logger or manually at intervals when visiting field sites. Preliminary results from Ellesmere Island illustrate frost creep, with heave continuing at ground temperatures of -25 to -30°C, and summer movements of active layer in response to thaw consolidation and precipitation.
Notes:

Keywords: 551.34 -- Geocryology. Frozen ground.
