This dataset includes heat flux and soil surface temperature data from a permafrost mound (i.e., lithalsa) located within the Tasiapik Valley, near the village of Umiujaq,...

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 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...

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...

This dataset includes groundwater level data from four wells located on a permafrost mound (lithalsa) and its surroundings, within the Tasiapik Valley, near the village of...

Permafrost peatland lakes are an organic-rich subcategory of thermokarst lakes and ponds that are known for their high rates of greenhouse gas emissions (Matveev et al. 2016)....

This dataset includes soil volumetric water content and temperature data from a permafrost mound (i.e., lithalsa) located within the Tasiapik Valley, near the village of...

The dataset in this issue of Nordicana D comprises data collected remotely using LiDAR elevation data in the St. Lawrence Lowlands area (i.e., Québec, Ontario, Vermont, New-York...

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...

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

Monitoring seasonal variation in arthropod abundance above or near the soil surface primarily allows us to determine the interannual availability of food resources for...

Arctic landscapes are characterized by the presence of many lakes and ponds that exhibit distinct physico-chemical and biological properties. Since 2018, we have been studying...

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...

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...

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...

Most of the world’s lakes are in the Arctic, yet very little is known about these aquatic environments. We present here the size and depth data for five large lakes in the...

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...

Northern terrestrial ecosystems are undergoing rapid transformation, potentially affecting the chemistry and microbial community structure in rivers flowing through them. 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...
