Serpentine (Floating) Ice Channels and their Interaction with Riverbed Permafrost in the Lena River Delta

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.

First pan-Arctic assessment of dissolved organic carbon in lakes of the permafrost region

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.

Permafrost Causes Unique Fine‐Scale Spatial Variability Across Tundra Soils

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.

Nunataryuk partner APECS is looking for a new host institution

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.
