Taking Scientific Measurements119 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.

Arctic Buildings118 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.

118 viewsA leaning weather station that has slowly started to melt out of the ice in recent years. We have snow-mobiled here (a one-hour trip) to steam-drill a new 6-meter (20-foot) hole and secure the station into it. Photo by John Maurer, CIRES/NSIDC, University of Colorado.

118 viewsAnother view of Nic making measurements in the snow (temperature and density profiles) and Koni steam-drilling. The wooden box contains batteries that run the instruments on the weather station.

118 viewsA close-up of the snow pit in the previous photo. At Swiss Camp this year, there were 1.2 meters (3.9 feet) of new snow that had accumulated in the past year that I had to dig through before reaching the hard, frozen ice of the ice sheet below.
