This data set reports the results of physical and chemical analyses of peat core samples from the SPRUCE experimental study plots located in the S1-Bog.

On August 13-15, 2012, a team of SPRUCE investigators and collaborators collected core samples of peat in the SPRUCE experimental plots. The goal was to characterize the biological, physical, and chemical characteristics of peat, and how those characteristics changed throughout the depth profile of the bog, prior to the initialization of the SPRUCE experimental warming and CO₂ treatments.

This data set provides the peat water content and peat temperature at time of sampling for peat cores collected before and during the SPRUCE Deep Peat Heating (DPH) study. Cores were collected during three sampling events: 03 June 2014, 09 September 2014, and 16 June 2015.

Two cores were extracted from hollow locations in each of the 10 experimental plots (4, 6, 8, 10, 11, 13, 16, 17, 19, and 20). Cores were partitioned into samples at 11 depth increments: 0-10, 10-20, 20-30, 30-40, 40-50, 50-75, 75-100, 100-125, 125-150, 150-175, and 175-200 cm below surface of the hollow.

This data set reports community-level CO₂ and CH₄ flux measurements for the SPRUCE experimental study plots located in the S1-Bog. Surface flux measurements of CO₂ and CH₄ were made using open-path analyzers over an area of 1.13 m² within each of 16 plots.  A custom-designed chamber encloses the hummock-hollow topography and allows point in time measurements of the shrub, forb, Sphagnum spp. and the complex microbial community.

This data set provides annual movies created from daily and twice daily images of vegetation stands in the S1 Bog showing the seasonal changes of vegetation and appearance and disappearance of snow for the period June 2010 through December 2015. Compiled movies are useful for examining the phenology of the bog and the changes to the landscape as experimental facilities have been constructed.
