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 dataset contains the percentage cover of plant species, bare ground and litter from twelve 1x1m vegetation monitoring plots. Plots are from two distinct vegetation communities (Herschel, Komakuk) approximately 500m apart. Plots were established in 1999 and monitored in 2004, 2009, 2013, 2014, 2015, 2016 and 2017. Data is presented as total percentage cover per species (not relative cover). Funding was provided by the NERC grant NE/M016323/1.
This dataset contains annual growth time series for 296 tundra shrubs belonging to 7 species (Salix and Betula genera) collected at the following sites in Northern Canada: Qikiqtaruk-Herschel Island (Yukon Territory), Kluane region (Yukon Territory), Umiujaq (Quebec) and Salluit (Quebec). Each individual time series (raw measurements) is presented along with the species and canopy size of the corresponding shrub. Funding was provided by the NERC grant NE/M016323/1.
This dataset contains phenological records (timing of life events such as the opening of flowers) for tundra plant species from eight 2x2m monitoring plots. Plots are from two distinct vegetation communities (Herschel, Komakuk, coded in the data as HER and KOM). Plots were established in 2016 and monitored in 2016 and 2017. Data are presented as phenological stages for each monitored plant individual at survey dates across the 2016 and 2017 growing seasons. Flower stalk length, leaf length and new growth length were measured in mm. Active layer depth was measured in cm and was recorded at the corner of each 2x2 m plot. Soil moisture was measured as a percentage. Funding was provided by the NERC grant NE/M016323/1.
This dataset contains plant trait measurements for nine plant functional traits (specific leaf area, vegetative height, reproductive height, seed mass, leaf dry matter content, wood density, leaf area, leaf fresh mass, leaf dry mass) collected in situ from tundra plant communities at three sites in the Yukon Territory, Canada. The three sites (Kluane Platueau (60.96 degN, 138.41 degW), Pika Camp (61.22 degN, 138.28 degW), Qikiqtaruk-Herschel Island (69.57 degN, 138.90 degW)) were visited annually from 2014-2017. Funding was provided by the NERC grant NE/M016323/1.
This dataset contains records of the number of open flowers per plant species in each 2x2m plot on different survey dates. Plots are from two distinct vegetation communities (Herschel, Komakuk, coded in the data as HER and KOM). Plots were monitored in 2017. Funding was provided by the NERC grant NE/M016323/1.
This dataset consists of measurements of leaf and root growth, species abundance and soil temperature made in ten subarctic plant communities located at the Arctic Biosphere Atmosphere Coupling at Multiple Scales (ABACUS) project sites near to Abisko, Sweden, and Kevo, Finland. The data were collected during the summer growing seasons (May to September) in 2008 and 2009, and comprise field survey measurements, temperature logs and values derived from analyses of mini-rhizotron images.
