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... -
Dissolved organic matter and bacterial data, along with associated...
Dissolved organic matter (DOM) leaching from thawing permafrost may have feedback effects on climate if it is efficiently mineralized into greenhouse gases (GHG). Yet, many... -
Ground surface temperatures, soil properties and vegetation cover in the...
During the summers of 2016, 2017 and 2018, field campaigns were conducted to study ice wedges and changes in the landscape of the Narsajuaq River Valley. The data presented here... -
Measured and simulated snow irradiance profiles as well as snow specific...
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... -
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,... -
Data from an experimental study to determine the impact of snow hardness on...
Lemmings are an essential link of the Arctic food web as they are the main prey of many predators inhabiting these regions. These small rodents exhibiting cyclic fluctuation of... -

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... -
Limnological and pigment data from the Great Whale River and surrounding...
Northern terrestrial ecosystems are undergoing rapid transformation, potentially affecting the chemistry and microbial community structure in rivers flowing through them. From 2... -
Groundwater level and temperature, Tasiapik Valley, Nunavik, Quebec
This dataset includes continuous water level data from four different wells within the Tasiapik Valley, near the village of Umiujaq, Nunavik, Quebec, Canada. The wells are... -

This dataset includes subsurface temperature data from four different sample locations within the Tasiapik Valley, near the village of Umiujaq, Nunavik, Quebec, Canada. Each... -
Cover data of vascular plants, cryptogams, and ground substrates at Alert...
Establishing new ecological baselines and initiating monitoring schemes on Arctic vegetation are critical to monitor, predict, and manage current and future impacts of climate... -
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... -
Ground temperatures of embankment subbase and subgrade at the Beaver Creek,...
The data is from two test sections of the Beaver Creek experimental road site (BC-RES) (62° 20' N, 140° 50' W; 649 m a.s.l.). The dataset covers the period 2/10/2008 -...
