Global inventory of subglacial lakes: (a) inventory of northern hemisphere subglacial lakes (SGLs); the top right inset shows the location of part a (red box) in the northern hemisphere; (b) inventory of SGLs beneath the Antarctic Ice Sheet; the extents of larger lakes (such as PEL Lake and Lake Vostok) are defined by blue polygons; red circles represent stable lakes identified from radio-echo sounding (RES), and blue triangles represent active lakes that have been observed to drain at least once during the observation period; lakes labeled in green have been accessed and cleanly sampled with the exception of Glacier de Tête Rousse, which was monitored using boreholes (water level) and sonar (cavity geometry), and Lake Vostok.
