Scientific Instruments182 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 Bears182 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.Feb 14, 2013

Polar Bears190 viewsBeyond the ridges of ice, dogs chase the polar bear, ensuring that it does not approach the camp. Image credit: EWG.Feb 14, 2013
06_polar_bears_03.jpg
Polar Bears169 viewsThe three dogs try to prevent the polar bear from coming out of the water, but the bear moves quickly and escapes into the icy terrain. Image credit: EWG.Feb 14, 2013

Polar Bears142 viewsHere the dogs investigate the polar bear as the polar bear retreats. Image credit: EWG.Feb 14, 2013

Taking Scientific Measurements142 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.Feb 14, 2013
06_polar_bears_01.jpg
Polar Bears148 viewsDogs provided companionship and entertainment for people living in the station camp, and they also alerted the camp when polar bears were present. Here, dogs are approaching a polar bear as it emerges from a lead (crack) in the ice. Image credit: EWG.Feb 14, 2013
05_taking_measurements_08.jpg
Taking Scientific Measurements135 viewsNotice the granular structure of this ice, and how large the grains are. The ruler is marked in centimeters. Image credit: EWG.Feb 14, 2013

Taking Scientific Measurements157 viewsTwo station members traverse the snow survey line measuring snow density by weight. Image credit: EWG.Feb 14, 2013
05_taking_measurements_05.jpg
Taking Scientific Measurements153 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.
