This dataset consists of soil temperature profiles from permafrost in subarctic Canada. Soil temperature profiles were monitored during summer in 2013 and 2014 in Yukon and Northwest Territories. Monitored sites included peatland plateaus, thawing features of peatland plateaus, unburnt and burnt black spruce forests, and additional sites.

This dataset contains methane fluxes from peatland plateaus and thawing peatland plateaus and from burnt and unburnt forests from permafrost in subarctic Canada. Methane fluxes were monitored during summer in 2013 and 2014 in Yukon and Northwest Territories. Monitored sites included peatland plateaus and thawing features of peatland plateaus.

This dataset consists of soil dates determined using radiocarbon in profiles from permafrost in subarctic Canada. Depth-specific soil core samples were dated using radiocarbon. Soil cores were sampled during early summer in 2013 and 2014. Each year soil cores were sampled from a peatland plateau, thawing features of the peatland plateau, unburnt and burnt black spruce forests, and additional sites in Yukon and Northwest Territories.

Data comprise sub-hourly discharge measurements including mean stream height, discharge and stream temperature collected at station S2 on the Siksik stream, North West Territories, Canada, between September 2009 and March 2010. Measurements were taken at a field site based at SikSik Creek a small sub-catchment of the Trail Valley Creek, approximately 60km north of Inuvik. The data were collected under Project HYDRA, a NERC funded UK research project linking Heriot Watt University, the Universities of Durham, Aberdeen and Stirling, and the Centre for Ecology & Hydrology (CEH), Edinburgh. Project HYDRA is part of the UK Arctic Research Programme. Project HYDRA studies sites in Arctic Canada to investigate the biological, chemical and physical controls on the release of greenhouse gases from permafrost into melt water and to the atmosphere and how these emissions will influence global warming.

This datasets contains measures of soil thaw depth from permafrost in subarctic Canada. Soil thaw depth was measured in 2013 and 2014 in sites from Yukon and Northwest Territories. Full details about this dataset can be found at https://doi.org/10.5285/fb88febb-9b53-4253-9856-7b35cbdf7080

This dataset consists of measurements of bulk density, carbon and nitrogen content in soil profiles from permafrost in subarctic Canada. Soil cores were sampled during early summer in 2013 and 2014. Soil cores were sampled from a peatland plateau and thawing features of the peatland plateau, and from an unburnt and burnt black spruce forest, and additional sites in Yukon and Northwest Territories. Full details about this dataset can be found at https://doi.org/10.5285/efa2a84b-3505-4221-a7da-12af3cdc1952

This dataset consists of autotrophic and heterotrophic soil respiration fluxes from peatland plateaus and thawing peatland plateaus and from burnt and unburnt forests from permafrost in subarctic Canada. Autotrophic and heterotrophic soil respiration fluxes (CO2) were monitored during summer in 2013 and 2014 in Yukon and Northwest Territories. Monitored sites included peatland plateaus, unburnt and burnt black spruce forests, and additional sites. Full details about this dataset can be found at https://doi.org/10.5285/061ba64c-d581-409b-b5af-009e5cabf0ce

This dataset contains laboratory measurements of peat depth, horizontal saturated hydraulic conductivity, dry bulk density, and the degree of peat humification (von Post scale) for degrading palsas at Rensjön palsa mire, Norrbotten, Sweden.

These data contain 408 instances of annual model output from JULES/IMOGEN simulations, covering the period between 1850-2100. Each simulation (which corresponds to one netcdf file) provides annual average of carbon stocks of the land, atmosphere and ocean store required to calculate the anthropogenic fossil fuel emissions as the residual of the yearly changes. Also included are the global warming variables, fractional land-cover, natural wetland extent and methane (CH4) flux and the soil temperature and moisture content for additional analysis. The spatial coverage is global with spatial resolution of the data is 2.5 degrees latitude, 3.75 degrees longitude. This dataset is the model output that was used in Comyn-Platt et al (2018) [ Comyn-Platt, E. et al. (2018). Carbon budgets for 1.5 and 2C targets lowered by natural wetland and permafrost feedbacks.
