    • Evidence for influx of Atlantic water masses to the Labrador Sea during the Last Glacial Maximum 

      Seidenkrantz, Marit-Solveig; Kuijpers, Antoon; Sørensen, Steffen Aagaard; Lindgreen, Holger; Olsen, Jesper; Pearce, Christof (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-21)
      The Last Glacial Maximum (LGM, 23–19,000 year BP) designates a period of extensive glacial extent and very cold conditions on the Northern Hemisphere. The strength of ocean circulation during this period has been highly debated. Based on investigations of two marine sediment cores from the Davis Strait (1033 m water depth) and the northern Labrador Sea (2381 m), we demonstrate a significant influx ...

    • Northeast Greenland (79.4 °N): Ice-free shelf edge around the Last Glacial Maximum 25.5-17.5 ka 

      Rasmussen, Tine Lander; Pearce, Christof; Andresen, Katrine Juul; Nielsen, Tove; Seidenkrantz, Marit Solveig (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-16)
      The size of the last glacial ice sheet on the Northeast (NE) Greenland shelf and its interaction with ocean circulation have been the subject of debate. Here we provide insights into the extent of the ice sheet around the Last Glacial Maximum (LGM) and investigate timing and strength of changes in the flow of Atlantic Water. The study is based on a multiproxy investigation of a marine sediment core, ...

    • Retreat patterns and dynamics of the former Norske Trough ice stream (NE Greenland): An integrated geomorphological and sedimentological approach 

      López-Quirós, Adrián; Junna, Tuomas; Davies, Joanna; Andresen, Katrine J.; Nielsen, Tove; Haghipour, Negar; Wacker, Lukas; Alstrup, Aage Kristian Olsen; Munk, Ole Lajord; Rasmussen, Tine Lander; Pearce, Christof; Seidenkrantz, Marit Solveig (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-09)
      A better understanding of past extent and dynamics of the Greenland Ice Sheet (GrIS) is required to provide context for present-day observations, to constrain numerical climate models and to predict future scenarios of ice-sheet response to recent climatic change. The presence of a grounded GrIS on the NE Greenland shelf during the Last Glacial Maximum (LGM) is supported by high-resolution seismic ...
