Polar Bears560 viewsNot all of the ice phenomena on the ice floes were naturally occurring. Station members sometimes made the most of their surroundings, witnessed in this polar bear made of snow. Image credit: EWG.

Taking Scientific Measurements463 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 Instruments455 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.

Polar Bears447 viewsThis station member was just climbing around on the ridges and hummocks of the ice floe, but, like all who ventured away from camp, he carried a rifle for protection from polar bears. Image credit: EWG.

Scientific Instruments439 viewsInstrument masts were insulated using mounds of hay to help keep them upright and prevent the snow from melting out from around them. Image credit: EWG.

Polar Bears438 viewsBeyond the ridges of ice, dogs chase the polar bear, ensuring that it does not approach the camp. Image credit: EWG.

Ice Hazards431 views"Pedestaling" occurs in summer because structures shade the ice and snow beneath from the sun's heat. Although this supply bag offers an example on a small scale, pedestaling frequently occurred around buildings and large structures. Image credit: EWG.

Scientific Instruments424 viewsWhen the anchors were not insulated, the snow melted out from around the mast bases, causing them to topple. Image credit: EWG.
