Supraglacial lakes like this one (which is about 0.75 miles in diameter) dot the surface of the Greenland ice sheet during the summer seasonal melt.
By better understanding these sudden drainages scientists hope to determine how supraglacial lakes will affect sea level rise as climate conditions shift in the future.
Greenland's many supraglacial lakes have been seen suddenly and mysteriously draining as climate change causes this region to warm, and now scientists have finally explained the mechanism behind this phenomenon.
We found that the volume of meltwater drained through this particular aquifer - crevasse field system is comparable to what comes out of a western Greenland supraglacial lake or river system.»
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.
