MARC recordRecent changes in areal extent of Devon Ice Cap, Nunavut, Canada / David O. Burgess, Martin J. Sharp.
| Title: | Recent changes in areal extent of Devon Ice Cap, Nunavut, Canada / David O. Burgess, Martin J. Sharp. |
| Author(s): | Burgess, David O. Sharp, Martin J. |
| Date: | 2004. |
| In: | Arctic, Antarctic, and Alpine Research. (2004.), Vol. 36(2) (2004) |
| Abstract: | Image data from 1959-1660 and 1999-2000 show a 2.4% decrease in surface area of Devon Ice Cap, Nunavut, owing to retreat of wastern tidewater glacier margins and shrinkage of south-western arm. Thinning has also increased bedrock exposure in interior, but north-western edge has advanced slightly since 1960. Volume loss calculated at -67 + or - 12 km³. Response time calculations indicate that most of ice cap is responding to recent climate warming, but north-western region responds to cooler conditions prevailing during Little Ice Age. |
| Notes: | Arctic, Antarctic, and Alpine Research. Vol. 36(2) :261-271 (2004). |
