SPRUCE Deep Peat Heating (DPH) Environmental Data, February 2014 through July 2105

This data set provides a record of the half-hourly automated environmental data collected for 14 SPRUCE plots (4, 5, 6, 7, 8, 10, 11, 13, 14, 16, 17, 19, 20, and 21) during the Deep Peat Heating (DPH) study. In June 2014, deep soil heating was initiated at 5 warming levels (+0, +2.25, +4.5, +6.75 and +9 °C) with 2 replicate plots per level. Measurements were underway before the initiation of heating treatments and continued through July 27 of 2015 at the transition to whole-ecosystem warming manipulations.

SPRUCE Peat Physical and Chemical Characteristics from Experimental Plot Cores, 2012

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.

Autochamber CO2 and CH4 Flux Data for the SPRUCE Experimental Plots

This data set reports measurements of CO2 and CH4 fluxes and d13C-CO2 and d13C-CH4 values associated with each flux measurement for the SPRUCE experimental study plots located in the S1-Bog. Flux measurements started in 2014 and are continuing.

EM123_combined data through December 10, 2015 have been uploaded.

This data set reports selected ambient environmental monitoring data from the S1bog. There are three monitoring sites located in the bog: Stations 1 and 2 are co-located at the southern end of the bog and Station 3 is located north central and adjacent to an existing U.S. Forest Service monitoring well.
