It is not easy to tell you how many we are - I have not even tried to count. Since more than three years we work on this project and it will take even longer to work on all the data and samples we will bring back to our labs and offices and to our partners all over the world.


After almost a 2-year hiatus from active research activities, our field campaigns are back on! This blog series will take you to the Canadian Arctic and onboard the CCGS Amundsen.


A new study, led by a number of Nunataryuk researchers, shows that optical and radar remote sensing can be used to map ice frozen to the riverbed (bedfast ice) vs. ice, resting on top of the unfrozen water layer (floating or so-called serpentine ice) within the Arctic’s largest delta, the Lena River Delta.


A first pan-Arctic assessment of dissolved organic carbon in lakes of the permafrost region is now published in Biogeosciences. Nunataryuk researcher and project coordination team member Michael Fritz from AWI in Potsdam contributed to this study with data from one of the Nunataryuk focal areas.


Nunataryuk researcher and project coordination team member Michael Fritz from AWI in Potsdam just published this study on paleo-ecology of the eastern Lena Delta in NE-Siberia in Frontiers in Earth Science


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


The new paper by Siewert et al. show that subsurface soil properties in permafrost tundra terrain exhibit tremendous spatial variability. They describe the subsurface variability of soil organic carbon (SOC) and ground ice content from the centimeter to the landscape scale in three typical tundra terrain types common across the Arctic region.


The funding agreement of the The Association of Polar Early Career Scientists (APECS) International Directorate with Alfred Wegener Institute is coming to an end in January 2022. While APECS will continue to have a project office at AWI Potsdam as as a hub for their numerous partnerships in EU Projects, they are currently looking for a new host for their international directorate.


The New study deals with thawing submarine permafrost, escaping methane and its apportionment sources.


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)


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


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.


New Updates from the Lena River despite the global pandemic. 



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"


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