MARC recordInvestigating climate change by digital analysis of blue ice extent on satellite images of Antarctica / Olav Orheim, Baerbel K. Lucchitta.
| Title: | Investigating climate change by digital analysis of blue ice extent on satellite images of Antarctica / Olav Orheim, Baerbel K. Lucchitta. |
| Author(s): | Orheim, Olav. Lucchitta, Baerbel K. |
| Date: | 1990. |
| In: | Annals of Glaciology. (1990.), Vol. 14 (1990) |
| Abstract: | Satellite data collected two years apart from identical area of Dronning Maud Land were analyzed to detect variations in surface features that may signal climatic change, and to establish this technique. Evidence suggests that blue ice extent is sensitive to changes in accumulation rate. Investigated blue ice area shows decrease in extent over two-year period caused by incursion of snow probably resulting from increase in accumulation rate. |
