MARC recordTransformation process observations of polar firn to ice / Chester C. Langway, Jr, Hitoshi Shoji, Atau Mitani, Henrik B. Clausen.
| Title: | Transformation process observations of polar firn to ice / Chester C. Langway, Jr, Hitoshi Shoji, Atau Mitani, Henrik B. Clausen. |
| Author(s): | Langway, Chester C., Shoji, Hitoshi. Mitani, Atau. Clausen, Henrik B. |
| Date: | 1993. |
| In: | Annals of Glaciology. (1993.), Vol. 18 (1993) |
| Abstract: | Transformation is very slow unless meltwater is present. Qualitative measure of variation of permeability with depth was determined for shallow ice cores from dry-zone regions in Greenland and Antarctica. Results provide insights into snow densification and pore close-off. Measurements show that bulk densities may be expressed as function of overburden; pore close-off takes place when overburden is 3.0 to 4.5 bar. |
| Notes: | Annals of Glaciology. Vol. 18 :199-202 (1993). |
