134 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.

Life on a Drifting Station133 viewsRecreation could include climbing the large ridges and hummocks on the ice station floe. These often reached 10 meters in height. During excursions like this, one of the men would typically carry a rifle for protection against polar bears. Image credit: EWG.

Taking Scientific Measurements132 viewsDetermining instrument location by theodolite. A theodolite is a high-precision surveying instrument. Because the ice floes rotated and changed in topography as they drifted, undergoing freezing and thawing, station members needed to regularly determine the position of the instruments relative to each other and to North.

Arctic Buildings131 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.
