Late-Glacial ice streams of the southeastern sector of the Scandinavian Ice Sheet and the asymmetry of its landforms
Reconstruction of glacial dynamics in the southeastern sector of the Scandinavian continental glacier indicates that the palaeo-ice streams were considerably persistent in time and space and their length depended on the width of peripheral cover of the continental glacier during retreat.

| Summary: | Reconstruction of glacial dynamics in the southeastern sector of the Scandinavian continental glacier indicates that the palaeo-ice streams were considerably persistent in time and space and their length depended on the width of peripheral cover of the continental glacier during retreat. Reconstruction of glacial dynamics in the southeastern sector of the Scandinavian continental glacier demonstrates that the westerly oriented parts of the glacial streams and lobes were more active than the other parts of the glacier. This is reflected in asymmetry of the eroded bedrock forms at the margins of glacial troughs and in the form of drumlins within troughs. For discussion it is proposed that the preferred rightward flow of the glacier during its movement was influenced by the Coriolis force directly or through the subglacial melt water dynamics. |
