    • Continental weathering and recovery from ocean nutrient stress during the Early Triassic Biotic Crisis 

      Knies, Jochen Manfred; Schönenberger, Jasmin; Zwingmann, Horst; van der Lelij, Roelant; Smelror, Morten; Vullum, Per Erik; Vogt, Christoph; Fredin, Ola; Muller, Alxel; Grasby, Stephen E.; Beauchamp, Benoit; Viola, Giulio (Peer reviewed; Journal article, 2022)
      Following the latest Permian extinction ∼252 million years ago, normal marine and terrestrial ecosystems did not recover for another 5-9 million years. The driver(s) for the Early Triassic biotic crisis, marked by high ...

    • Regional sea-level highstand triggered Holocene ice sheet thinning across coastal Dronning Maud Land, East Antarctica 

      Sugunuma, Yusuke; Kaneda, Heitaro; Mas e Braga, Martim; Ishiwa, Takeshige; Koyama, Takushi; Newall, Jennifer C.H.; Okuno, Jun'ichi; Obase, Takashi; Saito, Fuyuki; Rogozhina, Irina; Andersen, Jane Lund; Kawamata, Moto; Hirabayashi, Motohiro; Lifton, Nathaniel A.; Fredin, Ola; Harbor, Jonathan M.; Stroeven, Arjen P.; Abe-Ouchi, Ayako (Peer reviewed; Journal article, 2022)
      The East Antarctic Ice Sheet stores a vast amount of freshwater, which makes it the single largest potential contributor to future sea-level rise. However, the lack of well-constrained geological records of past ice sheet ...

    • The seismic reflection Moho across the mid-Norwegian continental rifted margin 

      Peron-Pinvidic, Gwenn (Peer reviewed; Journal article, 2022)
      The Moho – defined as the boundary that separates the Earth’s crust from the underlying upper mantle at depths of about 5 to 7 km beneath the oceans and 30 to 40 km below continents – has been difficult to pin down with ...

    • A thicker Antarctic ice stream during the mid-Pliocene warm period 

      Mas e Braga, Martim; Jones, Richard S.; Bernales, Jorge; Andersen, Jane Lund; Fredin, Ola; Morlighem, Mathieu; Koester, Alexandria J.; Lifton, Nathaniel A.; Harbor, Jonathan M.; Suganuma, Yusuke; Glasser, Neil F.; Rogozhina, Irina; Stroeven, Arjen P. (Peer reviewed; Journal article, 2023)
      Ice streams regulate most ice mass loss in Antarctica. Determining ice stream response to warmer conditions during the Pliocene could provide insights into their future behaviour, but this is hindered by a poor representation ...

    • A topographic hinge-zone divides coastal and inland ice dynamic regimes in East Antarctica 

      Andersen, Jane Lund; Newall, J.C.; Fredin, Ola; Glasser, Neil F.; Lifton, Nathaniel A.; Stuart, Finlay M.; Fabel, Derek; Caffee, Marc; Pedersen, Vivi K.; Koester, Alexandria; Sugunuma, Yusuke; Harbor, Jonathan M.; Stroeven, Arjen P. (Peer reviewed; Journal article, 2023)
      The impact of late Cenozoic climate on the East Antarctic Ice Sheet is uncertain. Poorly constrained patterns of relative ice thinning and thickening impair the reconstruction of past ice-sheet dynamics and global sea-level ...
