• Carbon Dioxide and Methane Release Following Abrupt Thaw of Pleistocene Permafrost Deposits in Arctic Siberia 

      Knoblauch, ChristianORCIDiD; Beer, ChristianORCIDiD; Schuett, Alexander; Sauerland, LewisORCIDiD; Liebner, SusanneORCIDiD; Steinhof, Axel; Rethemeyer, Janet; Grigoriev, Mikhail N.ORCIDiD; Faguet, Alexey; Pfeiffer, Eva‐Maria (Journal of Geophysical Research: Biogeosciences, 2021-11-01)
      The decomposition of thawing permafrost organic matter (OM) to the greenhouse gases (GHG) carbon dioxide (CO2) and methane forms a positive feedback to global climate change. Data on in situ GHG fluxes from thawing permafrost ...
    • Recent advances in the study of Arctic submarine permafrost 

      Angelopoulos, MichaelORCIDiD; Overduin, Pier P.ORCIDiD; Miesner, FrederiekeORCIDiD; Grigoriev, Mikhail N.ORCIDiD; Vasiliev, Alexander A.ORCIDiD (Permafrost and Periglacial Processes, 2020)
      Submarine permafrost is perennially cryotic earth material that lies offshore. Most submarine permafrost is relict terrestrial permafrost beneath the Arctic shelf seas, was inundated after the last glaciation, and has been ...
    • Thermokarst Lake to Lagoon Transitions in Eastern Siberia: Do Submerged Taliks Refreeze? 

      Angelopoulos, MichaelORCIDiD; Overduin, Pier PaulORCIDiD; Westermann, SebastianORCIDiD; Tronicke, JensORCIDiD; Strauss, JensORCIDiD; Schirrmeister, LutzORCIDiD; Biskaborn, Boris K.ORCIDiD; Liebner, SusanneORCIDiD; Maksimov, Georgii; Grigoriev, Mikhail N.ORCIDiD; Grosse, GuidoORCIDiD (Journal of Geophysical Research: Earth Surface, 2020)
      As the Arctic coast erodes, it drains thermokarst lakes, transforming them into lagoons, and, eventually, integrates them into subsea permafrost. Lagoons represent the first stage of a thermokarst lake transition to a ...
    • Thermo‐erosional valleys in Siberian ice‐rich permafrost 

      Morgenstern, Anne; Overduin, Pier PaulORCIDiD; Günther, Frank; Stettner, Samuel; Ramage, Justine; Schirrmeister, LutzORCIDiD; Grigoriev, Mikhail N.ORCIDiD; Grosse, GuidoORCIDiD (Permafrost and Periglacial Processes, 2020-10-28)
      Thermal erosion is a major mechanism of permafrost degradation, resulting in characteristic landforms. We inventory thermo‐erosional valleys in ice‐rich coastal lowlands adjacent to the Siberian Laptev Sea based on remote ...
