Stratigraphy and ground ice content of borehole 76:27/7-2 on Ellef Ringnes Island, Nunavut, Canada

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 1976-07-27 with a hand-held modified CRREL drill and is 2.2 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.

acknowledgement=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.

comments=The location of the borehole was given using the National Topographic System Grid Reference in the report, then repositioned manually to obtain GPS coordinates, so it should be considered approximate.

为量化加拿大努斯省埃尔勒夫·林内斯岛（NU）的地表体积，自1974年至1977年间，共钻探了100个钻孔，深度达3米。其中，1976年7月27日使用手持式改进的CRREL钻机钻探了一个钻孔，深度为2.2米。该数据集描述了活动层厚度、土壤层序、体积土壤冰含量以及地表沉积物。体积冰含量通过视觉估计和实验室测量的结合来确定。数据集版本为2，使用的网络CDF版本为4.7.3，HDF5版本为1.10.6。在恶劣气候条件下，A.C. Liard和W.G. Green（格雷厄姆岛，1974年）、R. O'Breham和W.R. Archer（埃尔勒夫·林内斯和克里斯蒂安国王岛，1976年）、C.N.D. Hotze和W.R. Archer（阿蒙德·林内斯、康沃尔和克里斯蒂安国王岛，1977年）提供了有价值的协助。1976年和1977年的航空支持由能源、矿产和资源部的极地大陆架项目提供。报告由L.A. Dredge博士审阅，提出了多项改进和替代解释的建议。结果数字化工作得到了PermafrostNet主题1的支持。钻孔位置采用国家地形系统网格参考在报告中给出，然后手动重新定位以获得GPS坐标，因此应视为近似值。数据集由加拿大地质调查局提供，数据来源于1982年报告《地表材料，南部埃尔勒夫·林内斯、克里斯蒂安国王和相邻岛屿，富兰克林区》的数字化版本；数据经手动转录，并对所有钻孔的某些字段进行了统一化处理（例如，地表沉积物、土壤材料）。项目名称为《地表材料和地貌过程，西部斯维德鲁普和相邻岛屿，富兰克林区》，项目ID为GSC_WSAI_1982。
