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 permafrost boreholes (TSP). Please consult parent dataset @ https://doi.org/10.1594/PANGAEA.842821...

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...

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

Arctic warming increases the degradation of permafrost soils but little is known about floodplain soils and other permafrost soils in the permafrost region. This dataset present...

Samoylov Island is centrally located within the Lena River Delta at 72° N, 126° E and lies within the Siberian zone of continuous permafrost. The landscape on Samoylov Island...

Active layer thickness (ALT) is one of currently two Essential Climate Variables related directly to permafrost regions as defined by the Global Climate Observing System (GCOS)...

Landsat data for Samoylov Island (Lena Delta, Siberia) was classified using a k-means unsupervised algorithm in the ENVI 4.7 software. Unsupervised classifications are based...

Polygonal tundra on Samoylov Island (Lena Delta, Siberia) was mapped from small-format aerial photography. Sub-metre resolution aerial images were obtained by mounting two Nikon...
