MARC recordGeometric and thermal evolution of a surge-type glacier in its quiescent state: Trapridge Glacier, Yukon Territory, Canada, 1969-89 / Garry K.C. Clarke, Erik W. Blake.
| Title: | Geometric and thermal evolution of a surge-type glacier in its quiescent state: Trapridge Glacier, Yukon Territory, Canada, 1969-89 / Garry K.C. Clarke, Erik W. Blake. |
| Author(s): | Clarke, Garry K. C. Blake, Erik W. |
| Date: | 1991. |
| In: | Journal of Glaciology. (1991.), Vol. 37(125) (1991) |
| Abstract: | Continuing study of this sub-polar glacier, reporting particularly on changes in geometry and thermal structure since 1968. Large wave-like bulge has formed near terminus, which is propagating at about 30 m a⁻¹. Since 1980, water penetration into ice has warmed 15-m temperature by 2°C. Zone of transition from warm- to cold-based ice is migrating down-glacier but at slower rate than bulge. This transition appears to be causing discontinuity in flow. |
