Ice Hazards18 viewsA small lead (or crack in the ice) has opened in the foreground. New leads, which form under wind stress when the ice diverges, were a constant threat to the camps. Camps often had to be relocated due to the sudden appearance of an ice lead through the middle of the camp (unless the crack appeared during summer and was simply a melt channel). Image credit: EWG.

124 viewsDuring the first year of the Antarctic Megadunes expedition, researchers found "pipes" in the hard-packed snow. The pipes start just beneath the surface and go down into the snow. One deep pipe, like the one shown here, was at least 6 feet (1.9 meters) deep. The pipes appear to be cracks that form near the surface of the ice and then freeze over.
