Arctic Buildings18 viewsDue to changes in the ice floe surface, it was not uncommon for camps to relocate to more stable ground. This photograph was taken during the rebuilding of the camp NP-22 in 1980. Aluminum tent poles are at the right, and an overturned boat is at the left. Image credit: EWG.

Taking Scientific Measurements17 viewsA ruler measures the ice freeboard, or the height of the ice above the water. Ice draft, on the other hand, is the depth of the ice below the surface of the water. Notice the elongated crystals. Image credit: EWG.

Antarctic Snow Dunes1075 viewsExtensive snow dunes wrinkle the surface of large parts of East and West Antarctica. The dunes are up to 100 kilometers long and separated by 2 to 4 kilometers, but only a few meters high. Comparison of modern satellite images with images acquired four decades earlier reveals that the dunes are nearly motionless.

91 viewsAn even closer close-up of the wall of the snow pit, showing a couple of layers in the snow. These particular kinds of layers form when big snow storms occur with strong winds that cause the snow to compact at what was then the surface. Other layers may be caused by melting and refreezing of snow. Photo by John Maurer, CIRES/NSIDC, University of Colorado.

105 viewsWhile Nic and Russ are off working on the weather station at NASA-SE, I'm digging another snow pit. This one is 2.5 meters (8 feet) deep! At that point, I reached the layer from the previous year's snow surface.
