Fig. 4: Examples of meltwater ponding in the Southwest Greenland Ice Sheet ablation zone imaged by drone.
From: Meltwater ponding has an underestimated radiative effect on the surface of the Greenland Ice Sheet
Locations of insets can be found in Fig. 3a. a–c There is negligible meltwater ponding (<0.1%) at the margins of the ice sheet due to crevasses and steep slopes. d–e In contrast, the upper ablation zone (1170–1290 m a.s.l.) on Jul 21, 2015 is characterized by vast numbers of small ponds, streams and larger supraglacial lakes and rivers that, in total, cover 3.6% of the imaged area (110 km2, see Fig. 3a). f Tents at our field site, surrounded by small streams and ponds.
