Paleo-Ecology of the Yedoma Ice Complex on Sobo-Sise Island (EasternLena Delta, Siberian Arctic)

The regional Yedoma records in the Lena Delta and on Bykovsky Peninsula confirm the existence of late Pleistocene tundra-steppe environments in West Beringia about 52 000 years ago.

Permafrost Carbon and CO2 Pathways Differ at Contrasting Coastal Erosion Sites in the Canadian Arctic

Paper led by George Tanski showing that carbon and CO2 pathways from coastal erosion in the Canadian Arctic differ greatly for different erosion types.

Permafrost Causes Unique Fine‐Scale Spatial Variability Across Tundra Soils

New study by Siewert et al. shows that subsurface soil properties in permafrost tundra terrain exhibit tremendous spatial variability.

Source apportionment of methane escaping the subsea permafrost system in the outer Eurasian Arctic Shelf

The East Siberian Arctic Shelf holds large amounts of inundated carbon and methane (CH4). Holocene warming, fortified by anthropogenic warming, has caused thawing of the underlying subsea permafrost.

A framework for studying risks from permafrost thaw

New study presents the development of a risk management framework adapted to the Arctic coastal context.

Population living on permafrost in the Arctic

This new study by Justine Ramage et al. is the first demographic study assessing the population living on permafrost and the impact of permafrost thaw on the population living in the Arctic Circumpolar Permafrost Region (ACPR).

Foldable map shows permafrost extent around the world

You can now download the new permafrost extent map as a foldable Dymaxion map.

Permafrost and the risk of anthrax transmission

A recent outbreak of anthrax disease, severely affecting reindeer herds in Siberia, has been reportedly associated topermafrost thaw.

The perception of permafrost thaw in the Sakha Republic (Russia): Narratives, culture and risk in the face of climate change

Arctic regions are currently undergoing unprecedented climatic and socio-environmental changes. Both scientific research and the observations and knowledge of Arctic residents provide detailed information about the multiplicity of transformations.

Keeping the sampling going! Monitoring Lena River biogeochemistry during the pandemic.

New Updates from the Lena River amid the global pandemic.

These cartoons add the cool factor to permafrost science

New story about Nunataryuk´s communication and dissemination efforts. "These cartoons add the cool factor to permafrost science - A multimedia science communication project combines art, game-playing, and augmented reality"

New Nunataryuk paper on source and fate of organic carbon from eroding permafrost coasts

Once released, organic carbon can be degraded and emitted as greenhouse gas to the atmosphere, or it can be stored away in marine sediments.

New Nunataryuk paper on modelling subsea methane emissions on East Siberian Arctic Shelf

Anaerobic oxidation of methane acts as an efficient barrier for upward migrating dissolved methane in East Siberian Arctic Shelf sediments.

The importance of disease modelling during a pandemic

The ongoing pandemic challenges global societies. Nunataryuk scientists of the University Ca'Foscari in Venice have been analysing and modelling the COVID-19 outbreak and spreading trends in Italy. They have used similar epidemiological models for a study within Nunataryuk to predict anthrax disease in Arctic regions.

Identifying Drivers of Seasonality in Lena River Biogeochemistry and Dissolved Organic Matter Fluxes

New Paper! Arctic river monitoring is necessary to observe changes in the mobilization of dissolved organic matter (DOM) from permafrost. The Lena River is the second largest Arctic river and 71% of its catchment is continuous permafrost.
