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.
