Mackenzie Distributaries. Illustration of a complex network of meandering, branching river channels. The rivers are shown in dark blue, with colours ranging from light blue to white away from the channels. Lighter colours denote elevations that are higher than the nearest river channel.
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
Two maps side by side showing the (left) North and (right) south pole, with a wiggly line coloured from dark blue through green to yellow showing the path of the magnetic pole over the last ~400 years.
