Spitsbergen 2023

Spitsbergen. We had two main goals: Firstly, we maintained the Bayelva permafrost observatory where multiple air, snow, soil, and permafrost parameters have been measured since 1998. And secondly, we measured [...] elevations using a high-accuracy GPS antenna to estimate surface subsidence resulting from thawing permafrost. In addition, we visited research sites of local and international partners and discussed scientific

in WP5. Methods will include quantification of land to ocean carbon transport from glacier and permafrost melting and analysis of POC degradability and POC/DOC concentration and composition, organic matter

Permafrost Resources

the subject of permafrost tell stories about living and working on and with permafrost. This series of videos with comics and animations explains what permafrost is what effect permafrost thaw has on the [...] science and wrote a eulogy for permafrost for the year 2322, in which she looks back at how we treated or rather neglected permafrost over the past 300 years. CT scan of a permafrost core Analysis Videos The [...] Brandenburg. Degradation of cold ice-rich permafrost: How do ice-rich permafrost respond to a warming climate?

LTO Bayelva

(Photo: Julia Boike) Observational data density in the permafrost region is low. At the Bayelva site close to Ny-Ålesund, Svalbard, the mean permafrost temperature is −2.8 °C, with a zero-amplitude depth [...] layer, temperature down to 9 m in the permafrost. Since the data provide observations of temporally variable parameters that mitigate energy fluxes between permafrost and atmosphere, they are suitable for [...] for use in integrating, calibrating and testing permafrost as a component in earth system models.

Between Arctic Land and Sea

investigation into the rapidly changing permafrost regions in the northern hemisphere. The project seeks to answer pressing questions about the role of permafrost thaw in the global climate system, and [...] the people living in these regions. The culmination of this ambitious endeavour is the "Arctic Permafrost Atlas," a ground-breaking publication set to launch during the Arctic Circle Assembly on October

New study simulates greatly reduced permafrost

Many of the models used to make climate projections are unable to dynamically reflect permafrost. A new study involving experts from the Alfred Wegener Institute has for the first time applied an extensive [...] extensive ensemble of 17 climate models to quantify how said models portray permafrost in warm climates. Drawing on a comparison of models for a warm period during the mid-Pliocene roughly three million years [...] Proceedings of the National Academy of Sciences the researchers conclude that the near-surface permafrost extent was less than 10 percent of that seen in the preindustrial era.

Submarine Permafrost

Profile submarine permafrost (Foto: Volker Rachold /AWI) (Photo: Alfred Wegener Institut) What is submarine permafrost? Subsea permafrost in the Arctic is generally relict terrestrial permafrost, inundated after [...] Why is it important? Submarine permafrost is similar to its terrestrial counterpart, but lies beneath the coastal seas. And as with terrestrial permafrost, subsea permafrost is a substantial reservoir and/or [...] of submarine permafrost and the influence of future climate system changes on submarine permafrost. Key lines of inquiry include: seasonal and interannual variability of sea floor permafrost boundary conditions

Methane

In In the framework of MOSES and in cooperation with [...] institutes (AWI-Periglacial Research, GFZ, Geomar) we plan to assess the influence of rapidly thawing permafrost on the distribution of methane in the aquatic environment. Especially the winter situation, the
