Polar Bears113 viewsHere the dogs investigate the polar bear as the polar bear retreats. Image credit: EWG.Feb 14, 2013

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.Feb 14, 2013

Polar Bears119 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

Taking Scientific Measurements112 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 Measurements122 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 Measurements120 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.

Taking Scientific Measurements127 viewsA lone station member taking snow line (snow survey) measurements. Image credit: EWG.Feb 14, 2013

Taking Scientific Measurements127 viewsNot all measurements required venturing outside. Aerologists Makurin and Ippolitov recording radio-sounding data at NP-16 in 1968. Image credit: EWG.Feb 14, 2013

Taking Scientific Measurements125 viewsGerman Maximov collecting the measurement of direct solar radiation. Image credit: EWG.Feb 14, 2013

Ice Hazards113 viewsDuring summer, melt ponds posed hazards to the camp. Here, a station member rows an inflatable raft in a melt pond that has formed in the middle of the camp at NP-6. Image credit: EWG.Feb 14, 2013
04_ice_hazards_07.jpg
Ice Hazards111 viewsWhen a pond melts, a whirlpool forms, emptying the pond in minutes. This photograph of a melt pond whirlpool is from NP-6. Image credit: EWG.Feb 14, 2013

Taking Scientific Measurements151 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).
