This dataset, called DARTS, comprises footprints of retrogressive thaw slump (RTS) and active layer detachments slides (ALD) identified and quantified using an automated deep... -
Pan-Arctic thermokarst lagoon distribution, area and classification from Landsat images, 1984 to 2021
Thermokarst lagoons develop in permafrost lowlands along the ice-rich Arctic coast when thermokarst lakes or basins with bottom elevations at or below sea level are breached by... -

Population in the Arctic Circumpolar Permafrost Region at settlement level, 2017
We defined permafrost settlements as settlements located within the permafrost extent, as modelled by Obu et al. (2019). The permafrost extent is based on the modeled... -
Settlements located within the permafrost extent in the Arctic Circumpolar Permafrost Region, 2017
We defined permafrost settlements as settlements located within the permafrost extent, as modelled by Obu et al. (2019). The permafrost extent is based on the modeled... -
Database of Ice-Rich Yedoma Permafrost (IRYP)
We synthesized data on the circum-Arctic and sub-Arctic distribution and thickness of Yedoma for compiling a preliminary circum-polar Yedoma map. For compiling this map, we used... -
Developing and Testing a Deep Learning Approach for Mapping Retrogressive Thaw Slumps (CA, RU)
In a warming Arctic, permafrost-related disturbances, such as retrogressive thaw slumps (RTS), are becoming more abundant and dynamic, with serious implications for permafrost... -
Holocene vegetation dynamics of circum-Arctic permafrost peatlands
Vegetation shifts in circum-Arctic permafrost peatlands drive feedbacks with important consequences for peatland carbon budgets and the extent of permafrost thaw under changing... -
The fractional land cover estimates from the Boreal–Arctic Wetland and Lake Dataset (BAWLD), 2021, Circum-Arctic
The Boreal and Arctic Wetland and Lake Dataset (BAWLD) provides estimates of fractional land cover of 19 land cover classes within 0.5° ×0.5° grid cells. The total area of the... -
Circumpolar Thermokarst Landscapes, 2015, Circum-Arctic
This data set provides the distribution of thermokarst landscapes in the boreal and tundra ecoregions within the northern circumpolar permafrost zones. This dataset provides an... -
Raster Circumpolar Arctic Vegetation Map (CAVM) from AVHRR, MODIS and elevation data
Land cover maps are the basic data layer required for understanding and modeling ecological patterns and processes. The Circumpolar Arctic Vegetation Map (CAVM), produced in... -
Permafrost Region Pond and Lake Database (PeRL)
The Permafrost Region Pond and Lake Database (PeRL) presents the results of a circum-arctic effort to map ponds and lakes from modern (2002-2013) high-resolution aerial and... -
Database of Ice-Rich Yedoma Permafrost Version 2 (IRYP v2)
Ice-rich permafrost in the circum-Arctic and sub-Arctic, such as late Pleistocene Yedoma, are especially prone to degradation due to climate change or human activity. When... -
Circumpolar raster grids of permafrost extent and geohazard potential for near-future climate scenarios
One of the consequences of warming climate is rising ground temperatures and degradation of perennially frozen ground, permafrost. Thawing of near-surface permafrost can cause... -
Remotely-sensed Arctic Discharge Reanalysis (RADR) from discharge observations and Landsat, 1984-2018, Circum-Arctic
Arctic rivers drain ~15% of the global land surface and significantly influence local communities and economies, freshwater and marine ecosystems, and global climate. However,... -
