attribute	NC_GLOBAL	summary	String	To quantify the ground volumes on Ellef Ringnes Island NU, Canada), 100 boreholes were drilled to depths up to 3 meters from 1974 to 1977. This borehole was drilled on 1976-07-24 with a hand-held modified CRREL drill and is 1.05 m deep. The dataset describes active layer thickness, soil stratigraphy, volumetric ground ice content, and surface deposits. Volumetric ice content was determined with a combination of visual estimates and laboratory measurements.
