Schefferville Permafrost Temperature Database, Version 1

This data set consists of ground temperature data from 192 boreholes in the area of Schefferville, Quebec (54°48'N, 66°50'W), located within the discontinuous permafrost zone. Temperature cables were installed at the Barney, Fleming, Knox mine, Timmins, Ferriman, Howse, Lance, Pinx, Red and Star ore deposits. Borehole depths ranged from 4 to 137 m, with the majority of boreholes being between 25 and 125 m deep. Data are provided for the period between 1957 to 1982. The length of record varies from only one temperature record to records greater than 10 years in length, with the longest record being 16 years long. The data are provided in both an MS Access database and tab-delimited ASCII formats. The database consists of two tables: one which contains information for individual boreholes, such as location and length of record, and a second table that contains the ground temperature data for all boreholes. The two tables are linked by a unique borehole site number. Data are available via ftp..本数据集涵盖加拿大魁北克省谢夫维尔（Schefferville）区域内192个钻孔的地下温度数据，该区域地处不连续多年冻土带，地理坐标为北纬54°48′、西经66°50′。研究团队已在巴尼（Barney）、弗莱明（Fleming）、诺克斯（Knox）矿、蒂明斯（Timmins）、费里曼（Ferriman）、豪斯（Howse）、兰斯（Lance）、平克斯（Pinx）、雷德（Red）及斯塔（Star）各矿床布设温度电缆。钻孔深度范围为4米至137米，其中绝大多数钻孔的深度处于25米至125米区间。数据的覆盖时段为1957年至1982年，单条记录的时长跨度较大，从仅包含1条温度记录到时长超过10年不等，其中最长记录的时长为16年。数据以MS Access（Microsoft Access）数据库与制表符分隔ASCII格式两种形式提供。该数据库包含两张数据表：一张用于存储单个钻孔的相关信息（如钻孔位置与记录时长），另一张存储所有钻孔的地下温度数据，两张数据表通过唯一的钻孔站点编号建立关联。数据可通过FTP（File Transfer Protocol）获取。
