In ice-rich hummocky terrains spanning broad swaths of the Canadian Arctic, accelerating permafrost thaw and terrain subsidence (thermokarst) are exposing materials that were...

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...

This dataset presents a compilation of paleomagnetic records from glacigenic sedimentary sequences studied on Bylot Island (Nunavut). Discrete sediment samples were collected...

This dataset is about: Oxygen profiles in polygonal ponds. Please consult parent dataset @ https://doi.org/10.1594/PANGAEA.853641 for more information.

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...

This dataset is about: Organic carbon content, densities and porosity of soils in polygonal ponds. Please consult parent dataset @ https://doi.org/10.1594/PANGAEA.853641 for...

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'...

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...

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...

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...

This dataset was collected during an autumn campaign in 2015 in Umiujaq, Northern Quebec. The dataset includes vertical profiles of 1) snow specific surface area (SSA), 2) snow...
