MARC recordA computer model along a flow-line of an ice dome--"captured ice shelf" / Ulf Erlingsson.
| Title: | A computer model along a flow-line of an ice dome--"captured ice shelf" / Ulf Erlingsson. |
| Author(s): | Erlingsson, Ulf. |
| Date: | 1994. |
| In: | Geografiska Annaler. Series A. Physical Geography. (1994.), Vol. 76A(1-2) (1994) |
| Abstract: | Examines captured ice-shelf hypothesis through construction of numerical model. Model calculates evolution of ice-surface profile in one-year steps. Flow of ice into and out of each 1000 m-long panel is calculated, and ablation and accumulation are added, together with effect of normal strain. Model also calculates mass balance for subglacial captured water. Results show that quick glacier advance is possible, although final equilibrium situation of model runs do not include any captured ice shelf. This is to be expected since it lacks any stabilizing feedback mechanism, being unstable feature with life time of few 1000s to several 10s of 1000s of years. |
