attribute NC_GLOBAL acknowledgement String Willing and able assistance in an unpleasant climate was given by A.C. Liard and W .G. Green (Graham Island, 1974); R. O'Breham and W.R. Archer (Ellef Ringners and King Christian islands, 1976); C.N.D. Hotze! and W.R. Archer (Amund Ringnes, Cornwall, and King Christian islands, 1977). Aircraft support in 1976 and 1977 was provided by Polar Continental Shelf Project of the Department of Energy, Mines and Resources. The report was critically read by Dr. L.A. Dredge, who suggested a number of improvements and alternative interpretations. Result digitizing was supported by PermafrostNet Theme 1.

attribute NC_GLOBAL summary String To quantify the ground volumes on Amund Ringnes Island NU, Canada), 100 boreholes were drilled to depths up to 3 meters from 1974 to 1977. This borehole was drilled on 1977-07-16 with a hand-held modified CRREL drill and is 2.5 m deep. The dataset describes active layer thickness, soil stratigraphy and characteristics (grain size analyses, soil liquid limit, plastic limit, plasticity index, carbonate content, pH), volumetric ground ice content, and surface deposits. Soil characteristics were determined in the laboratory, and volumetric ice content was determined with a combination of visual estimates and laboratory measurements.
