On board a Russian Arktika-class nuclear icebreaker, Sergey Dolya took some incredible photos from the air, in an expedition to the North Pole in the polar night.
This photograph by an astronaut on the Space Station highlights the snout of the Upsala Glacier (49.88°S, 73.3°W) on the Argentine side of the North Patagonian Icefield. Dark lines of rocky debris (moraine) within the ice give a sense of the slow ice flow from right to left. Image © NASA/M. Justin Wilkinson
The major goal of the campaign CryoVex, was to look at how ESA’s CryoSat mission can be used to understand the thickness of sea ice in Antarctica. The scenes look like, explorers are landed with a spacecraft on the surface of Jupiter’s moon Europa, or some other icy alien world. Image © Stefan Hendricks, Alfred Wegner Institute
