Soil properties and computed tomography scans (CT-scans) of two...
This dataset presents data on soil properties (volumetric ice content, organic matter content, grain size) that come from two thermo-erosion gullies that were studied in the... -
Thaw front depth at the bottom, on the slopes and on the adjacent tundra...
This dataset presents thaw front depths (TFD) measurements made in two thermo-erosional gullies on Bylot Island, Nunavut, Canada, from probing to refusal with a graduated steel... -
Paleomagnetic data from sedimentary sequences on Bylot Island, Nunavut.
This dataset presents a compilation of paleomagnetic records from glacigenic sedimentary sequences studied on Bylot Island (Nunavut). Discrete sediment samples were collected... -
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... -
Meteorological, snow and soil data on shrub tundra at Bylot Island, Canadian...
These data were obtained on shrub tundra (Salix richardsonii) in the Canadian high Arctic, in Qarlikturvik valley on Bylot Island at 73°11'N, 79°45'W. A 1-year time series of... -
Morphometry of glacial lakes formed in front of glaciers C-93 and C-79
In formerly glaciated permafrost regions, extensive areas are still underlain by a considerable amount of glacier ice buried by glacigenic sediments. Although the extent and... -
Meteorological, snow and soil data from Bylot Island, Canadian High Arctic,...
These data were obtained in an ice-wedge polygonal site in the Canadian high Arctic, in Qarlikturvik valley on Bylot Island at 73.15°N. The site is on herb tundra with no erect... -
Radiocarbon (14C) dates in terrestrial and aquatic environments, Bylot...
This dataset compiles radiocarbon (14C) dates obtained from soil and lake sediment samples collected at Bylot Island, Nunavut. Bulk soil/sediment samples and, when present,... -
Relative abundance of tundra bird and mammal species encountered daily on...
Many vertebrate species in tundra communities occur in low abundance but may play an important role in terrestrial food webs. Although estimates of their absolute abundance may... -
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... -
Above-ground biomass of graminoid plants inside and outside goose grazing...
Primary production is at the base of all terrestrial food webs. In terrestrial ecosystem, primary production is measured by sampling the vegetation. We are interested in two... -
Computed tomography (CT) scans of a lake sediment core, Bylot Island,...
Computed tomographic (CT) scanning was used (August 2015) to analyze a 109 cm-long lake sediment core from a thermokarst lake in Bylot Island, Nunavut, Canada. The core was... -
Ground-penetrating radar (GPR) survey data for a thermokarst lake, Bylot...
Ground-penetrating radar (GPR) lines were collected (May 2015) at Gull Lake (Bylot Island, Nunavut, Canada) using sleigh-dragged Sensors and Software PulseEkko GPR and 50 MHz... -
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... -
Fossil diatom abundance in a lake sediment core, Bylot Island, Nunavut, Canada
This dataset presents all the fossil diatom species identified in a 109 cm-long lake sediment core from a thermokarst lake in Bylot Island, Nunavut, Canada. The core was... -
Monitoring of avian predator reproduction on Bylot Island, Nunavut, Canada
Predators play a key role in the functioning of ecosystems and could potentially control the abundance of their prey. As predators are at the top of the food chain, they can be... -
Monitoring of Lapland longspur reproduction on Bylot Island, Nunavut, Canada
The Lapland longspur (Calcarius lapponicus) is one of the most abundant and visible terrestrial songbird breeding in the Arctic. As other Arctic-nesting birds, they are... -
Monitoring of Greater Snow Goose reproduction on Bylot Island, Nunavut, Canada
Nest searches are carried out on foot from our main field station since 1989 and from a secondary field camp inside the main goose colony since 1992. Nests are found during... -
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... -
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...
