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.
Cores were collected from 16 experimental plots; samples were collected from the hummock and hollow surfaces to depths of 200-300 cm in defined increments. Three replicate cores were collected from both hummock and hollow locations in each plot. The coring locations within each plot were mapped.
User note: Related data containing characteristics of peat following a similar methodology collected 5 years post-treatment (2020-21), as well as a summary of data contained in this dataset are available, please see SPRUCE Peat Physical and Chemical Characteristics from Experimental Plot Cores, Select Pre-Treatment 2012 and Post-Treatment 2020-21.
