Winter conditions profoundly alter the limnological properties of lotic ecosystems. In 2019, from February 25 to March 1, we sampled the under-ice water column of the Great Whale River and its plume into Hudson Bay. This limnological and pigment dataset is complementary to an amplicon dataset (prokaryotes and microbial eukaryotes) and a metagenomic dataset that are available at the NCBI Sequence Read Archive (BioProject PRJNA999265 and PRJNA999354). It includes data for nutrients (total nitrogen and phosphorus), carbon (dissolved organic and inorganic), dissolved organic carbon characterization (SUVA254, SR, a320, S289), cell abundance measured by flow cytometry, total suspended sediment concentration, specific conductivity, snow depth, ice thickness, under-ice water depth, oxygen concentration, temperature and pigments determined by high-performance liquid chromatography.

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 Umiujaq, Nunavik, Quebec, Canada. The water levels are measured continuously within an unconfined sandy aquifer at the top (1 well; Sommet 1/TOP 1) and the side (2 wells; Côté 1/SIDE 1, Côté 2/SIDE 2) of the permafrost mound. Additionally, the water level is measured in a well (Silt 1/SILT 1) installed in a confining silt layer located below the superficial aquifer. Data were collected from 16 July 2014 – 28 June 2021 with Solinst Levelogger® water level dataloggers. Soils stratigraphy and well construction details are given below. These data support the article Fortier et al. (2023).

Subgrid processes occur in various ecosystems and landscapes but, because of their small scale, they are not represented or poorly parameterized in climate models. These local heterogeneities are often important or even fundamental for energy and carbon balances. This is especially true for northern peatlands and in particular for the polygonal tundra, where methane emissions are strongly influenced by spatial soil heterogeneities. We present a stochastic model for the surface topography of polygonal tundra using Poisson–Voronoi diagrams and we compare the results with available recent field studies. We analyze seasonal dynamics of water table variations and the landscape response under different scenarios of precipitation income. We upscale methane fluxes by using a simple idealized model for methane emission. Hydraulic interconnectivities and large-scale drainage may also be investigated through percolation properties and thresholds in the Voronoi graph. The model captures the main statistical characteristics of the landscape topography, such as polygon area and surface properties as well as the water balance. This approach enables us to statistically relate large-scale properties of the system to the main small-scale processes within the single polygons.

This data set contains two years of calibrated continuous in situ water vapour isotopic observations conducted since July 2015 in the east-Siberian Lena delta, at the research station on the Samoylov Island (72°22'N, 126°29'E). The temporal resolution of this data set is of 1 hour. The measurements have been performed with a Cavity RingDown Spectrometer located in a heated container outside the main station. The ambient air inlet is located at 5 m above the ground level. Calibration is achieved via the measurement of liquid water standards injected with a custom-made system including a vapourizer and a dew-point generator (bubbler).

The data presents characteristic of the spatial pattern of vegetation and data of snow patches disappearance in 2 nival gullies located on the Beskid Mt. and the Uhrocie Kasprowe Mt. in the Tatra Mountains. The gullies are located above the upper timberline (i.e. 1500 m a.s.l) in subalpine and alpine belts. Quantitative studies of the vegetation were carried out in sample plots of 0.5 × 0.5 m, located 0.5 m apart, along the cross-profiles of the studied nival gullies. For each sample plot, the cover of the following was determined: vascular plants, bryophytes, plant litter, rocks, coarse debris, finer materials. The plant species present in the plot were recorded. Species cover (in %) was estimated using the cover class method (Daubenmire 1959). Slope inclination was measured using an inclinometer. 13 cross-profiles were taken along the longitudinal profile of nival gully on the Beskid Mt. and 10 cross-profiles along the longitudinal profile of nival gully on the Uhrocie Kasprowe Mt. The length of the transect corresponded to the width of the nival gully. The survey of the phases of disappearance of snow patches, was carried out in two or three subsequent time spans in 1990-1991. The thickness of the snow patches was measured every 1 metre along the same cross-profiles as vegetation . Measurements were made with an avalanche measuring rod. The coverage of each plant species was correlated with the thickness of a snow patch. It was found that there are species that correlate positively or negatively with the snow patch thickness. This is manifested by the decrease in the number of species as the snow thickness increases. Two species, Luzula spadicea and Festuca picta, can be recognised as indicators of the sites with long-lasting snow cover.

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 zooplankton communities of more than 22 lakes and 13 freshwater ponds located on southern Victoria Island, Cambridge Bay, Nunavut (69°N, 105°W). For each of the lakes and ponds sampled, zooplankton communities were collected and specimens were identified to species. In total, more than 77 different species were found, including 56 rotifers, 6 copepods, 11 cladocerans, 2 fairy shrimps, a mysid and a tadpole shrimp.

The summer water balance of a typical Siberian polygonal tundra catchment is investigated in order to identify the spatial and temporal dynamics of its main hydrological processes. The results show that, besides precipitation and evapotranspiration, lateral flow considerably influences the site-specific hydrological conditions. The prominent microtopography of the polygonal tundra strongly controls lateral flow and storage behaviour of the investigated catchment. Intact rims of low-centred polygons build hydrological barriers, which release storage water later in summer than polygons with degraded rims and troughs above degraded ice wedges. The barrier function of rims is strongly controlled by soil thaw, which opens new subsurface flow paths and increases subsurface hydrological connectivity. Therefore, soil thaw dynamics determine the magnitude and timing of subsurface outflow and the redistribution of storage within the catchment. Hydraulic conductivities in the elevated polygonal rims sharply decrease with the transition from organic to mineral layers. This interface causes a rapid shallow subsurface drainage of rainwater towards the depressed polygon centres and troughs. The re-release of storage water from the centres through deeper and less conductive layers helps maintain a high water table in the surface drainage network of troughs throughout the summer.
