| Summary: | Abstract. — During the autumn 1980 a subglacial river was discovered traced upstream and mapped under the "Loven Est" (Spitsbergen). In the absence of knowledge of the water's origin it was possible in spring 1981 to understand the role of the subglacial run-off in the formation of the ice sheet in front of the glacier. The detailed observation of this distinctive locale has made possible the understanding of its formation and évolution. Lastly this article surveys the studies of other ice sheets and permanent flows known in Spitsbergen. Résumé. — Une rivière sous-glaciaire a été découverte remontée et cartographiée à l'automne 1980 sous le glacier Loven Est (Spitsberg). A défaut de connaître l'origine de l'eau il nous a été possible au printemps 1981 de saisir le rôle de l'écoulement sous-glaciaire dans la formation de marges glacées au front du glacier. L'observation minutieuse de ce milieu original a permis de comprendre son élaboration et son évolution. Enfin cet article fait le point sur les autres marges glacées et écoulements permanents connus au Spitsberg. |
