MARC recordCo-isotopic signature of two mechanisms of basal-ice formation in Arctic outlet glaciers / Roland Souchez, R.D. (Reginald D.) Lorrain, J.-L. Tison, Jean Jouzel.
| Title: | Co-isotopic signature of two mechanisms of basal-ice formation in Arctic outlet glaciers / Roland Souchez, R.D. (Reginald D.) Lorrain, J.-L. Tison, Jean Jouzel. |
| Author(s): | Souchez, Roland. Lorrain, R. D. Tison, J. -L. Jouzel, Jean. |
| Date: | 1988. |
| Publisher: | Cambridge: International Glaciological Society |
| In: | Annals of Glaciology. (1988.), Vol. 10 (1988) |
| Abstract: | Basal ice is formed by regelation as consequence of both pressure-melting and freezing-on at glacier sole. Study of D/H and ¹⁸O/¹⁶O ratios in basal ice from five Arctic glaciers indicates that co-isotopic signature exists for these two mechanisms of formation. Dispersed and stratified facies of basal ice are related, respectively, to occurrence of regelation and to freezing-on at glacier base. Origin is tentatively connected with onset of basal sliding and zone of bed decoupling due to basal water pressure in these glaciers. |
