Climate station data from the Salluit Region in Nunavik, Quebec, Canada
Data are from the Salluit region in Nunavik, Québec, Canada. It contains data from air and ground temperatures and wind speed and direction. The available datasets cover the... -
Carbon, nitrogen and water content of the active layer from sites across the...
It is presumed that significant quantities of carbon are stored in permafrost soils and that the thawing permafrost could substantially raise atmospheric carbon dioxide... -
Winter under-ice limnological and pigment data of the Great Whale River and...
Winter conditions profoundly alter the limnological properties of lotic ecosystems. In 2019, from February 25 to March 1, we sampled the under-ice water column of the Great... -
Circumpolar Arctic lake oxygen data from 1954-2019
A database was created following a systematic review process as carried out for a review article titled "Oxygen depletion in Arctic lakes: circumpolar trends, biogeochemical... -
Measurements of thaw front depth, surface organic layer thickness, soil...
Between June 2017 and September 2022, fieldwork was conducted in Old Crow Flats, Yukon (Canada) to study thermokarst lake and drained basin dynamics and hydrological connections... -
Concentrations, fluxes and isotopic signatures of greenhouse gases emitted...
Arctic lakes and ponds can be hot spots for greenhouse gas (GHG) emissions, yet studies are scarce, particularly outside the peak summer season. Here we present GHG diffusive... -
Organic matter content and grain size distribution in lake sediment cores,...
This dataset presents an estimation of the organic matter content (by loss-on-ignition) and particle size (grain size analysis) in two lake sediment cores (109 cm, 114 cm) from... -
Monitoring of arctic and red fox reproduction on Bylot Island, Nunavut, Canada
Foxes are strongly dependent on dens for parturition and rearing of cubs. Due to the shallow permafrost-free layer in most of the arctic fox’s range, new dens are rarely dug and... -
Coastal Labrador peatland permafrost inventory
Northern peatlands cover approximately four million km², and about half of these peatlands are estimated to contain permafrost and periglacial landforms, like palsas and peat... -
Tundra Nunavik: Set of 27 interpolated bioclimate variables derived from the...
While most ecological studies focus on the impact of climate change on some populations or species, broader, ecosystem-based information is needed to better predict the future... -
Dissolved organic carbon and related environmental data from ponds and lakes...
Frozen tundra soils hold one of the Earth’s largest pools of organic carbon. With global warming, permafrost is thawing at an accelerated rate, promoting the formation of... -
Pollen analysis of buried glacier ice and sediments
This dataset presents a compilation of sporo-pollinic taxa detected in glacier ice buried in the permafrost of Bylot Island. The buried ice was sampled using an earth auger... -
Limnological and pigment data for surface waters along a hydrological...
Northern terrestrial ecosystems are undergoing rapid transformation, potentially affecting the chemistry and microbial community structure in rivers flowing through them. The... -
Particulate matter and dissolved organic carbon concentrations in northern...
Ice covers northern lakes for much of the year and has biological and biogeochemical properties that differ from those in the underlying water. Since 2017, we have studied lake... -
Drill logs, visible ice content and core photos from 2015 surficial drilling...
These data were collected as a part of the Slave Province surficial materials and permafrost study (SPSMPS) which took place near the Ekati mine, north of Lac de Gras. Data... -
Lemming monitoring on Bylot Island, Nunavut, Canada
Lemming abundance and demography are monitored using three methods: Capture by snap trapping is done using Museum Special traps at three sites during the summer from mid-July to... -
Climate station data from Purple Valley at the head of Milne Fiord, northern...
This dataset provides a long-term weather record from Purple Valley, Ellesmere Island. This location is near the head of Milne Fiord and can serve as an index location for the... -
Soil temperature and soil water content measurements near Umiujaq and in the...
In northern regions, the seasonal Freeze Thaw (FT) is among climatic phenomenon having major impacts on terrestrial photosynthesis and respiration as well as soil evaporation... -
Isotope characterization of ground ice on Bylot Island
Over the past decades, observations of buried glacier ice exposed in thaw-slump affected terrain of the Arctic indicate that considerable amounts of Pleistocene glacier ice... -
Curated reference database of SSU rRNA for northern marine and freshwater...
High throughput sequencing technologies, such as Roche 454 pyrosequencing and Illumina can enable semi-quantitative study of communities of single-celled organisms by generating...
