A map titled: Barnes Ice Cap, Baffin Island, Nunavut, Canada. The map is comprised of a Sentinel-2 RGB image satellite image showing the ice cap which is up to 60 km across and in excess of 100 km long. Surrounding the ice cap are mountains, some with snow covered peaks, others rocky, along with many bright blue lakes. Overlaid on top of the ice cap are flow lines indicating the direction of ice flow, and colored according to the speed of flow. The lines clearly show the ice divide in the middle of the ice cap. The color of the flow lines is on a logarithmic scale from 0 to 100 m/yr, as shown in the color-bar beneath the main plot. In the upper left is an inset showing where Baffin Island's position to the west of Greenland, and above the north eastern limit of North America.

A satellite image showing a few outlet glaciers in west Greenland. Two are labelled: In orange: Kangaasarssup Sermia (KS) and in blue Isortuarsuup Sermia (IS). An inset shows a close up of the terminus of IS where ice bergs can be seen in the lake.
Three subplots, the two on the left cover the same extent, and the one on the right shows a smaller area contained within. The top left shows change in ice veloicty (green=faster, pink=slower). There is no pink, and the intensity of green increases towards the glacier. In the lower left the rate of surface elevation change is shown where red=thinning, blue=thickening; much of the glacier has thinned with the greatest thinning near the terminus. Two water bodies indicate some increases in elevation, however dh/dt values over water are not to be trusted. On the right, a close up satellite image of a glacier terminus with multiple terminus traces shown for a 6 year 2014-2020 period. Some terminus retreat is visible at the northern end of the glacier, near some grounded icebergs
