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...

Mapped thermokarst ice wedge polygon patterns from WorldView-1, 2009, Ebe-Basyn-Sise Island, SW Lena Delta, Siberia (RU)
Detailed calculations of ground-ice volumes in permafrost deposits are necessary to understand and quantify the response of permafrost landscapes to thermal disturbance and...
-
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...

Quantification of shoreline movements from satellite remote sensing, 1951-2011, Yukon Territory mainland coast (CA)
The Arctic is warming, but the impacts on its coasts are not well documented. To better understand the reaction of Arctic coasts to increasing environmental pressure, shoreline...

Annual dynamics of rapid permafrost disturbances from Landsat and Sentinel-2, 2000-2019, Northeast Siberia (RU)
Permafrost is warming globally which leads to widespread permafrost thaw. Particularly ice-rich permafrost is vulnerable to rapid thaw and erosion, impacting whole landscapes...

Mapped polygon pattern geomorphometry from HRSC-AX, 2009, Act-IWS Adventdalen, Svalbard (NO)
Polygonal systems formed by thermal contraction cracking are complex landscape features widespread in terrestrial periglacial regions. The manner in which cracking occurs is...

Growing season, non-growing season and annual CH4 fluxes from temperate, boreal, and Arctic wetlands and uplands,...
Wetlands are the single largest natural source of atmospheric methane (CH4), a greenhouse gas, and occur extensively in the northern hemisphere. Large discrepancies remain...

Cumulative greenhouse gas production in thawed sediments, 2019-2020, Yukechi Alas, Central Yakutia (RU)
This dataset describes two 17 m long sediment cores taken from beneath two thermokarst lakes in the Yukechi Alas, Central Yakutia, Russia. The first core was taken from below an...
