Taking Scientific Measurements17 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 Bears17 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 Measurements17 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 Measurements20 viewsTwo station members traverse the snow survey line measuring snow density by weight. Image credit: EWG.Feb 14, 2013

Taking Scientific Measurements19 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.

Ice Hazards17 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

Ice Hazards18 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 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).
