Seasonal monitoring of arthropod abundance at Bylot Island, Nunavut
Monitoring seasonal variation in arthropod abundance above or near the soil surface primarily allows us to determine the interannual availability of food resources for... -
Seasonal ice cover and catchment changes at northern thermokarst ponds in...
Thermokarst ponds and lakes are common features of Arctic and subarctic landscapes, developing in depressions that result from the thawing of ice-rich permafrost. Most of these... -
Retrogressive thaw slump activity and related lake colour change in five...
This database contains the spatial coordinates and years (timing and duration) of activity for more than 7400 retrogressive thaw slumps (RTS) in five areas of the western... -
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... -
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,... -
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... -
Phytoplankton pigments of lakes and fiords of Northern Ellesmere Island,...
Phytoplankton communities in Arctic lakes and fiords are diverse despite oligotrophic conditions. Phytoplankton pigment analyses allow the estimation of the potential primary... -
Permafrost geochemistry and retrogressive thaw slump morphology (Peel...
In ice-rich hummocky terrains spanning broad swaths of the Canadian Arctic, accelerating permafrost thaw and terrain subsidence (thermokarst) are exposing materials that were... -
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... -
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... -
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... -
Northern Ellesmere Island ice shelf and ice tongue extents
The ice shelves along the northern coast of Ellesmere Island have been in a state of decline since at least the early 20th century. Available data derived from explorers'... -
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... -
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... -
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... -
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... -
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... -
Meteorological data at the Beaver Creek, Yukon - Road experimental section...
The dataset presents the measurement of the meteorological data at the Beaver Creek experimental road site, Yukon (BC-RES) (62° 20' N, 140° 50' W; 649 m above sea level). The... -
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...
