| Abstract: | Examines sediment cascade in Arctic glacier basin in context of paraglacial activity, considering: delivery of ice-marginal sediments onto glacier surface; capture of sediments by supraglacial streams; and routing of suspended sediment supraglacially and then glacially to portal at side margin. Reports observations of paraglacial sediment activity and portal-stream suspended sediment flux over four days at cold-based valley glacier. Argues that stochastic pulses observed in water turbidity are driven not by discharge, but by delivery of water-saturated sediments to glacier surface from ice-marginal debris flows and subsequent transfer via glacial drainage system. Discusses importance of paraglacial component in sediment cascade of deglaciating basins and interpretation of stochastic pulses in turbidity records. |
