Ice Hazards18 viewsA small lead (or crack in the ice) has opened in the foreground. New leads, which form under wind stress when the ice diverges, were a constant threat to the camps. Camps often had to be relocated due to the sudden appearance of an ice lead through the middle of the camp (unless the crack appeared during summer and was simply a melt channel). Image credit: EWG.

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.

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.

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.

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.

Scientific Instruments26 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.

Scientific Instruments25 viewsWhen the anchors were not insulated, the snow melted out from around the mast bases, causing them to topple. Image credit: EWG.

NASA IceBridge2005 viewsThe Operation IceBridge mission, initiated in 2009, collects airborne remote sensing measurements to bridge the gap between NASA's Ice, Cloud and Land Elevation Satellite (ICESat-I) mission and the upcoming ICESat-II mission. This photo was taken over the Patagonian ice fields, on November 23, 2009.

Allan Hills913 viewsThe Allan Hills are located on the flanks of the TransAntarctic Mountains. Ice upwells onto the hills where combinations of winds and solar insolation cause the ice to quickly ablate. Meteorites that once fell over a large region of East Antarctica have been carried by glacier motion into this small locality.
