MARC recordSnow-accumulation variability from seasonal surface observations and firn-core stratigraphy, eastern Wilkes Land, Antarctica / Ian D. Goodwin.
| Title: | Snow-accumulation variability from seasonal surface observations and firn-core stratigraphy, eastern Wilkes Land, Antarctica / Ian D. Goodwin. |
| Author(s): | Goodwin, Ian D. |
| Date: | 1991. |
| In: | Journal of Glaciology. (1991.), Vol. 37(127) (1991) |
| Abstract: | Annual accumulation records were derived from two firn cores drilled along 2000 m contour, separated by 750 km. Records, spanning 1930-85, show that annual accumulation has increased by 25% from 1960 to 1985, resulting in highest rates in 55-year records. Annual accumulation layers were identified in firn cores using firn-stratigraphic model together with seasonal oxygen-isotope ratios. Suggests that increase is result of changes in general atmospheric circulation pattern, which have produced higher annual frequency of precipitation events. |
