Record #96888:

Frost heave of subaqueous lake-bottom sediments, Mackenzie delta, Northwest Territories / C.R. Burn.

Title: Frost heave of subaqueous lake-bottom sediments, Mackenzie delta, Northwest Territories / C.R. Burn.
Author(s): Burn, C. R.
Date: 1989.
Publisher: Ottawa: Geological Survey of Canada
In: Geological Survey of Canada. Paper. (1989.), Vol. 89-1D (1989)
Abstract: Measurements at four sites near Inuvik in winter 1987-88. Maximum lake thickness in March was 90 cm; maximum measured frost penetration into bottom sediments was 130 cm. Frost heave of up to 20 cm was found, with ice segregation accounting for 15% of total displacement. Segregated ice lenses 0.5 to 2 cm thick were common in core samples.
