Abstract

This data set reports the results of total gaseous mercury (TGM) flux monitoring conducted in a sub-set of the SPRUCE experimental study enclosures (Plots 4, 6, 10, 13, 17 and 19) located in the S1 Bog. These plots were selected to represent duplicates of the +0, +4.5 and +9°C experimental temperature treatments. Monitoring of TGM fluxes was conducted in May-June 2014, August 2014 and June 2015 to capture the influence of the deep (2 m below the ground surface) peat warming experiment. These sampling events were conducted prior to the initiation of deep peat warming (May-June 2014), once target peat temperatures were achieved at depth (August 2014) and at the conclusion of the deep warming experiment prior to the initiation of whole ecosystem warming (June 2015). This data set also presents the total mercury (Hg) concentration for peat samples collected during the group sampling campaigns, involving a team of SPRUCE investigators and collaborators, in June 2014 (prior to deep peat warming experiment), September 2014 (target temperatures achieved at depth) and June 2015 (end of deep warming experiment and prior to whole ecosystem warming). Peat samples for total mercury analysis were collected from Enclosures 4, 6, 8, 10, 11, 13, 16,more » 17, 19, 20.« less

SPRUCE Peat Mercury, Methylmercury and Sulfur Concentrations from Experimental Plot Cores, Beginning in 2014

Dataset Pierce, C.E. ; Psarska, S. ; Brozowski, J. ; ...

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 in northern Minnesota, 40 km north of Grand Rapids in the USDA Forest Service Marcell Experimental Forest (MEF). Sample collection and analyses started in June of 2014 and will continue for the duration of the experiment. Core samples are collected annually from all 12 plots to a depth of 200cm in 10cm and 25cm increments. Samples are analyzed for total mercury concentration, methylmercury concentration, percent carbon, percent nitrogen, and percent sulfur.
SPRUCE Deep Peat Heating (DPH) Peat Water Content and Temperature for Experimental Plot Cores, June 2014 through June 2015

Dataset Kluber, Lauren A. ; Phillips, Jana R. ; Hanson, Paul J. ; ...

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). The five ambient plots (5, 7, 14, and 21) were not included in the DPH sampling efforts. See Table 1. Cores were partitioned into samples at 11 depth increments:more »« less
SPRUCE Deep Peat Heating (DPH) Environmental Data, February 2014 through July 2015

Dataset Hanson, P. J. ; Riggs, J. S. ; Nettles, W. R. ; ...

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. The DPH study was undertaken to evaluate possible rapid responses of deep peatmore »« less
SPRUCE Peat Mercury, Methylmercury and Sulfur Concentrations from Experimental Plot Cores, 2012

Dataset Pierce, Caroline E ; Furman, Olha S. ; Tfaily, Malak M. ; ...

This data set reports the results of analyses of peat core samples for total mercury and methylmercury, as well as carbon, nitrogen and sulfur. Samples were collected as part of a larger sampling campaign from the SPRUCE experimental study plots located in the S1-Bog. From 2012-08-13 to 2012-10-15, 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 andmore »« less
SPRUCE Deep Peat Heat (DPH) Metagenomes for Peat Samples Collected June 2015

Dataset Klumber, Laurel A. ; Yang, Zamin K. ; Schadt, Christopher W.

This data set provides links to the results of metagenomic analyses of 38 peat core samples collected on 16 June 2015 from SPRUCE experiment treatment plots after approximately one year of belowground heating. These metagenomes are archived in the U.S. Department of Energy Joint Genome Institute (DOE JGI) Integrated Microbial Genomes (IMG) system and are available at the accession numbers provided below and in the accompanying inventory file. This work was done in collaboration with the DOE Joint Genome Institute (JGI) study that is targeting understanding the microbial metagenomes of “fungal, bacterial, and archaeal communities mediating C cycling and tracemore »« less
