We conclude that the ice sheet surface is efficiently drained under optimal conditions, that digital elevation models alone can not fully describe supraglacial drainage and its connection to subglacial systems, and that predicting outflow from climate models alone, without recognition of subglacial processes, may overestimate true meltwater release from the ice sheet.

Moulin discharges mapped inside ∼ 52 % of the source ice watershed for Isortoq, a major proglacial river, totaled ∼ 41 — 98 % of observed proglacial discharge, highlighting the importance of supraglacial river drainage to true outflow from the ice edge. (pnas.org)
