Taking Scientific Measurements160 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 Buildings159 viewsAround some buildings in the summertime, "pedestaling" occurs because structures shade the ice and snow beneath from the sun's heat. Each subsequent summer adds to the height of the pedestal. This building on NP-22 reached 5 meters in height after seven years. Image credit: EWG.

Arctic Buildings157 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.
