    • Glacigenic landforms and sediments in Store Koldewey Trough, NE Greenland – preliminary results 

      Olsen, Ingrid Leirvik; Forwick, Matthias; Laberg, Jan Sverre; Rydningen, Tom Arne; Husum, Katrine (Conference object; Konferansebidrag, 2018-04)
      The glaciation history of NE Greenland remains poorly constrained, resulting in conceptual and uncertain reconstructions of the configuration of the Greenland Ice Sheet during the Last Glacial Maximum (c. 24-19 ka BP), as well as the timing and the dynamics of the deglaciation. New studies suggests that the ice sheet in NE Greenland probably was more dynamic than previously thought, extending all ...

    • Last glacial ice sheet dynamics offshore NE Greenland – a case study from Store Koldewey Trough 

      Olsen, Ingrid Leirvik; Rydningen, Tom Arne; Forwick, Matthias; Laberg, Jan Sverre; Husum, Katrine (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-04)
      The presence of a grounded Greenland Ice Sheet on the northeastern part of the Greenland continental shelf during the Last Glacial Maximum is supported by new swath bathymetry and high-resolution seismic data, supplemented with multi-proxy analyses of sediment gravity cores from Store Koldewey Trough. Subglacial till fills the trough, with an overlying drape of maximum 2.5 m thick glacier-proximal ...
