Manual active layer and and water table depth measurements from the autochamber sites at Stordalen Mire, northern Sweden (2003-2017)

Files: Active_Layer_Water_Table_03-17.xlsx - Data file, with main data in the "DATA" tab. IsoGenieSite_AL_WTD_MapsVisualNotes_200310.pdf - Visual notes on the measurement locations. The following site labels (with chamber numbers in parentheses) correspond to the main autochamber sites: Dry (1,3,5) = Palsa Autochamber Site Mesic (2,4,6) = Sphagnum Autochamber Site Wet (7,8) = Eriophorum Autochamber Site Water table depth (W D) was measured in wells. Active layer depth (A L) was measured by inserting a metal rod into the surface. The original instruction page is included in page 3 of the pdf. All depths are in centimeters (cm) below peat surface (i.e. peat or Sphagnum spp. vegetation surface = 0), with negative values indicating depth below the surface and positive values (for water table) indicating height of standing water above the surface. Blank data in the Palsa or water table column means no water table observed. Staff gauge was added July 2006 at the edge of a small pond in the fen visible from the shack, with measurements reported in meters. All other measures are in cm.

Active_Layer_Water_Table_03-17.xlsx：数据文件，主体数据存储于名为“DATA”的工作表中。 2. IsoGenieSite_AL_WTD_MapsVisualNotes_200310.pdf：测量点位的可视化说明文档。 以下样地标识（括号内为自动监测室编号）对应核心自动监测室样地： 干燥区（1、3、5号室）= 泥炭丘（Palsa）自动监测室样地 中湿区（2、4、6号室）= 泥炭藓（Sphagnum）自动监测室样地 湿地区（7、8号室）= 羊胡子草（Eriophorum）自动监测室样地 地下水位深度（Water Table Depth, WTD）通过井体测定。活动层厚度（Active Layer Depth, ALD）采用金属杆插入地表的方式获取，该测定方法的原始操作说明收录于上述PDF文档的第3页。 所有深度均以泥炭表面（即泥炭或泥炭藓属植被表面为基准零点）为参照，单位为厘米（cm）：负值代表测点位于地表以下，地下水位对应的正值代表地表以上积水高度。泥炭丘样地或地下水位列中的空白数据表示未观测到地下水位。 2006年7月，在观测小屋可见的沼泽小型池塘边缘增设了人工水位标尺，其测量单位为米（m）；其余所有测量的单位均为厘米（cm）。 资助与致谢： 本研究感谢瑞典极地研究秘书处（Swedish Polar Research Secretariat）与SITES对阿比斯库科学研究站相关工作的支持，SITES由瑞典研究理事会项目编号4.3-2021-00164资助。 本研究为EMERGE生物学整合研究所（EMERGE Biology Integration Institute）的成果之一，该机构由美国国家科学基金会生物学整合研究所项目资助（项目编号：2022070）。IsoGenie项目（为本研究测量期间的多数工作提供资助）由美国能源部生物与环境研究办公室基因组科学项目资助，资助编号分别为DE-SC0004632、DE-SC0010580及DE-SC0016440。
