Main publication details
MARC recordFrost 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. |
| Notes: | Geological Survey of Canada. Paper. Vol. 89-1D :85-93 (1989). |
