The relationship between supraglacial debris and meltwater streams on the Sylgjujökull outlet glacier, Vatnajökull, Iceland / Julian A. Dowdeswell.
Title: | The relationship between supraglacial debris and meltwater streams on the Sylgjujökull outlet glacier, Vatnajökull, Iceland / Julian A. Dowdeswell. |
Author(s): | Dowdeswell, Julian A. |
Date: | 1980. |
Abstract: | Examines four themes relating to links between supraglacial debris and meltwater streams: origin and distribution of supraglacial debris, stressing importance of debris-rich layers as debris source and proposing model of supraglacial sediment distribution on quiescent stage surging glaciers (e.g. Sylgjujökull); stream initiation and debris entrainment, discussing channel initiation at transient snowline, influence of ice structures and annual/perennial nature of observed supraglacial streams; debris influence on stream morphometry, comparing streams with and without significant debris load; supraglacial resedimentation, examining "resedimented debris train" formation on drifted snow low on Sylgjujökull snout, and discussing process implications for dirt cone development. |
