We present the first ecosystem-scale methane flux data from a northern Siberian tundra ecosystem covering the entire snow-free period from spring thaw until initial freeze-back....

These data represent five high-latitude sites studied in the PAGE21 project (https://www.page21.eu): Samoylov, Kytalyk, Abisko, Zackenberg and Bayelva. Please see the linked...

This data set includes meteorological, soil, permafrost data obtained from the long term observational site Samoylov, located in the Lena River Delta, Siberia, between 1998 to...

The datasets present hydrographic measurements on discharge and suspended supply in the Lena River Delta in the summer periods from 2002 to 2012. Water discharge was calculated...

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...

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...

Although ponds make up roughly half of the total area of surface water in permafrost landscapes, their relevance to carbon dioxide emissions on a landscape scale has, to date,...

This dataset is about: Global Terrestrial Network for Permafrost metadata for active layer monitoring (CALM) sites. Please consult parent dataset @...

Methane (CH4) production, oxidation, and emission were studied in ponds of the permafrost-affected polygonal tundra in northeast Siberia. Microbial degradation of organic matter...

Small-format aerial images were taken in summer 2007 of Samoylov Island from from heights between 600 m and 800 m. Images overlapped so that photogrammetric methods allowed the...

Understanding permafrost processes and changes requires long-term observational datasets. This dataset is a continuation of the dataset available from the long-term...

The Arctic is changing rapidly as strong air temperature warming induces a multitude of feedback mechanisms including changes in the snow cover and warming and thawing of...

The datasets present measurements of cDOM absorption in channels of the Lena River in the Lena River Delta during the summer periods from 2013-2016 and the spring periods from...

The datasets present measurements of cDOM absorption in lakesin the Lena River Delta during the summer periods from 2013-2016 and the spring periods from 2015-2016. Water...

Requirements for space based monitoring of permafrost features had been already defined within the IGOS Cryosphere Theme Report at the start of the IPY in 2007 (IGOS, 2007). The...

The Permafrost Thaw Action Group is committed to the standardized field data collection necessary to quantify permafrost thaw dynamics across circumarctic regions. This effort...
