The Aldo Pontremoli Mooring (MAP), operated by the Institute of Polar Sciences of the National Research Council (CNR), has been active in the Kongsfjord, located in the Svalbard...

Aerosol particles that can aid the formation of ice crystals in clouds are known as ice nucleating particles (INPs). These particles play a critical role in Arctic cloud...

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...

Despite the importance of surface energy budgets (SEBs) for land-climate interactions in the Arctic, uncertainties in their prediction persist. In situ observational data of SEB...

The chemical characteristics of lakes change according to local conditions in their watershed: soil type, vegetation type, proximity to the coast, etc. We studied 49 lakes...

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

Current warming, shifting hydrological regimes and accelerated permafrost thaw in the catchment of the Arctic rivers will affect their water biogeochemistry. The Lena River is...

This dataset consists of over 2000 snow depth and position (GNSS) measurements collected on Samoylov and Kurungnakh Islands in the Lena Delta, Russia, between March 31st and...

Lemming abundance and demography are monitored using three methods: Capture by snap trapping was done using Museum Special traps at three sites during the summer from mid-July...

This dataset contains observations of water discharge rates and concentrations of dissolved organic carbon (DOC) and dissolved inorganic carbon (DIC) from a polygonal tundra...

Ignoring small-scale heterogeneities in Arctic land cover may bias estimates of water, heat and carbon fluxes in large-scale climate and ecosystem models. We investigated...

This dataset contains two sub-datasets: 1) A land cover classification for the Holocene terrace on Samoylov island. The land cover classification is based on a high-resolution...

A comprehensive sediment survey carried out at the lakes of SITES Water to assess the main sediment characteristics (water content, organic carbon (C) and nitrogen (N) content...

Observation of ice and snow depth and thickness of the SITES Water lakes. Abisko Scientific Research Station (2026). Lake ice and snow depth/thickness from Almbergasjön,...

The folder Lake_Points contains the different lake-shapefiles. Each file has bathymetry- and shoreline-points for the interpolation. Shoreline points have heights of 0 meter....

This data set provides lake bathymetry data for three lakes situated in a large thermokarst basin (alas) in the ice-rich permafrost deposits (Yedoma-type Ice Complex) of...

Freshwater input in the Kongsfjorden (FIKO) Project Start: 2010-06-01 End:2020-12-31 FIKO project aims to acquire measurements of the chemical and physical characteristics of...
