Sentences with phrase «by supraglacial lakes»

Low surface water storage (3.6 ± 0.9 cm), negligible impoundment by supraglacial lakes or topographic depressions, and high discharge to moulins (2.54 — 2.81 cm ⋅ d − 1) indicate that the surface drainage system conveyed its own storage volume every < 2 d to the bed.

The role of supraglacial lakes in this has been a point of emphasis; Luthje et al, (2006) noted that the area covered by supraglacial lakes was independent of the summer melt rate, but controlled by topography.
