Permafrost soil database with information on site, topography, geomorphology, hydrology, soil stratigraphy, soil carbon, ground ice isotopes, and vegetation at thermokarst features near Toolik and Noatak River, 2009-2013

This database contains soil and permafrost stratigraphy associated with thermokarst features near Toolik Lake and the Noatak River collected by Torre Jorgenson and Andrew Balser during summers 2009-2011. The Access Database has main data tables (tbl_) for site (environmental), soil stratigraphy, soil physical data, soil chemical data, soil isotopes (ground ice), soil radiocarbon dates, topography and bathymetry, and vegetation cover. The site data includes information of location, observers, geomorphology, topography, hydrology, soil summary characteristics, pH and EC, soil classification, and vegetation cover by species. Soil stratigrapy has information on soil texture and ground ice. Soil physical and chemical data includes lab data on bulk density, moisture, carbon, and nitrogen. The database has 37 reference tables (REF_) that have codes and descriptions for variables used in site, soil stratigraphy, and vegetation cover tables.

本数据库收录了由Torre Jorgenson与Andrew Balser于2009至2011年夏季，在图利克湖（Toolik Lake）与诺阿塔克河（Noatak River）附近采集的、与热喀斯特地貌（thermokarst features）相关的土壤与永久冻土地层序数据。该Access数据库包含主数据表（以tbl_为前缀），涵盖场地（环境）、土壤地层序、土壤物理数据、土壤化学数据、土壤同位素（地下冰）、土壤放射性碳测年数据、地形与水深数据以及植被覆盖数据。其中场地数据表包含位置、观测者、地貌学、地形学、水文学、土壤综合特征、pH值与电导率（EC）、土壤分类以及按物种划分的植被覆盖等信息。土壤地层序数据表涵盖土壤质地与地下冰相关内容。土壤物理与化学数据表包含容重、含水量、碳与氮的实验室分析数据。本数据库另有37个参考数据表（以REF_为前缀），用于对场地、土壤地层序及植被覆盖数据表中所使用变量的编码与含义进行说明。
