Life on a Drifting Station15 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.

Arctic Buildings18 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.

Taking Scientific Measurements29 viewsOne of the primary purposes of the drifting stations was to collect all possible meteorological data while on the ice floe. This involved installing, calibrating, and maintaining the instruments. Here, researcher German Maximov conducts a routine calibration of a pyranometer (in the large tube). Image credit: EWG.

Scientific Instruments26 viewsStation members were responsible for recording measurements from a variety of different instruments. Shown here is an array of meteorological instruments at NP-21. From left are the instrument for solar radiation measurement (pyranometer, albedometer, actinometer and balancemeter), the shelter housing thermometers for air temperature and humidity and the hair hygrometer, the precipitation gauge (Tetrakov type), and the anemometer, which is mounted on a mast at 10 meters.

Arctic Sea Ice News & Analysis2672 viewsThis image compares the average sea ice extent for September 2007 to September 2005; the magenta line indicates the long-term median from 1979 to 2000. September 2007 sea ice extent was 4.28 million square kilometers (1.65 million square miles), compared to 5.57 million square kilometers (2.14 million square miles) in September 2005. This image is from the NSIDC Sea Ice Index.
