Yedoma Permafrost Landscapes as Past Archives, Present and Future Change Areas The Research Topic „Yedoma permafrost landscapes as past archives, present and future change areas” was published in Frontiers [...] this Yedoma Research Topic represent a broad view on current know-ledge in permafrost research with respect to Yedoma permafrost landscapes. Since about 150 years research was undertaken to highlight the [...] Frontiers in Earth Science in July 2022. Ice-rich permafrost deposits of late Pleistocene age (Yedoma Ice Complex) covered several million km² of the Arctic main land between the Taymyr Peninsula and the Yukon
grains and aquatic organisms e.g. diatom valves and chironomids from lake sediment archives or permafrost deposits. Microfossil analyses are used to investigate spatial and temporal changes and environmental
the palaeogenetics lab we analyse ancient DNA from sediment cores (lakes or marine archives) or permafrost deposits. We apply DNA metabarcoding and metagenomics (shotgun and hybridisation capture) to i [...] into pre-PCR and main rooms) Isolation of ancient DNA from ancient samples (e.g. lake sediment, permafrost) DNA library preparation of ancient DNA for shot-gun sequencing Lab equipment includes UV workstations
Upscaling of permafrost region field measurements with remote sensing Generating permafrost remote sensing datasets suitable for model parametrization and validation Making geospatial permafrost datasets available [...] and other permafrost-region disturbance dynamics Mapping periglacial geomorphology, land surface changes, and surface deformation Advancing machine learning and deep learning for permafrost region remote [...] Laboratories Sedimentology Aim: Study of transport and accumulation processes of permafrost-related deposits Classification of sediment sequences in general Parameters: Sediment structure description
orientation of research projects include scientific applications of stable isotope methods in permafrost research, palaeoclimate studies, by also in the fields of limnology, hydrology, ecology and glaciology
a result, the permafrost ground will thaw and the coasts will erode more heavily. This will particularly be a problem in areas where settlements and houses have been built on permafrost. Here we’re talking

studies in the permafrost regions, which deal with the past and future fate of frozen ground, carbon cycling, coastal erosion, and changes in ecology (AWI Research Division: Permafrost Research and Research [...] funding of 2.75 million euros for the operation of the Potsdam InnoLab for Arctic Research . Air, Permafrost, Vegetation and Climate of the Past These elements provide Potsdam's polar researchers with the

(Graphic: Alfred-Wegener-Institut) Global warming and the thawing of permafrost not only lead to destabilization of the soil in the permafrost regions of the Arctic, but also to a tendency to increasingly delimit [...] risk assessment is therefore crucial from an economic as well as ecological point of view. The permafrost model CryoGrid, which has been further developed as part of PermaRisk, is intended to help predict
