Fig. 4: Ice surface elevation change (2011–2020) on 5 subglacial lake networks.
From: Detection of 85 new active subglacial lakes in Antarctica from a decade of CryoSat-2 data
a Lambert Glacier, b Vanderford Glacier, c David Glacier, d Stockholm Glacier, e Français Glacier. Time series of inside-lake elevation anomalies measured for each subglacial lake (left) in the network, with CryoSat-2 surface elevation change maps (right). Derived boundaries (black, pink, blue, green in ascending distance from the grounding zone), and previously identified lakes (grey dashed lines)11 are illustrated. Subglacial hydrological pathways (blue) modelled from Bedmap2 bed elevation data14 show a possible hydrological connection between lakes lying along a subglacial stream. Background image is the 125 m MODIS mosaic67. Black arrows show approximate ice flow direction.
