    • Distinct modes of meltwater drainage and landform development beneath the last Barents Sea ice sheet 

      Shackleton, Calvin; Patton, Henry; Winsborrow, Monica; Esteves, Mariana; Bjarnadòttir, Lilja Rùn; Andreassen, Karin Marie (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-18)
      The flow of glacial ice is impacted by basal meltwater drainage systems that fluctuate on a continuum from distributed, high-pressure environments to channelized, lower pressure networks. Understanding the long-term development of dominant drainage modes and impacts on ice flow and landform development is a crucial step in predicting palaeo and contemporary ice-mass response to changes in ...

    • Evidence for a Highly Dynamic West Antarctic Ice Sheet During the Pliocene 

      Gohl, Karsten; Uenzelmann-Neben, Gabriele; Gille-Petzoldt, Johanna; Hillenbrand, Claus-Dieter; Klages, Johann P.; Bohaty, Steven M.; Passchier, Sandra; Frederichs, Thomas; Wellner, Julia S.; Lamb, Rachel; Leitchenkov, G; Klaus, A.; Kulhanek, D.; Bauersachs, T.; Courtillat, M.; Cowan, E.; De Lira Mota, Lira; Esteves, Mariana; Fegyveresi, J.; Gao, L.; Halberstadt, A.; Horikawa, K.; Iwai, M.; Kim, J.; King, T.; Penkrot, M.; Prebble, J.; Rahaman, W.; Reinardy, B.; Renaudie, J.; Robinson, D.; Scherer, R.; Siddoway, C.; Wu, L.; Yamane, M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-03)
      Major ice loss in the Amundsen Sea sector of the West Antarctic Ice Sheet (WAIS) is hypothesized to have triggered ice sheet collapses during past warm periods such as those in the Pliocene. International Ocean Discovery Program (IODP) Expedition 379 recovered continuous late Miocene to Holocene sediments from a sediment drift on the continental rise, allowing assessment of sedimentation processes ...

    • The role of ocean and atmospheric dynamics in the marine-based collapse of the last Eurasian Ice Sheet 

      Sejrup, Hans Petter; Hjelstuen, Berit Oline Blihovde; Patton, Henry; Esteves, Mariana; Winsborrow, Monica; Rasmussen, Tine Lander; Andreassen, Karin Marie; Hubbard, Alun Lloyd (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-19)
      Information from former ice sheets may provide important context for understanding the response of today’s ice sheets to forcing mechanisms. Here we present a reconstruction of the last deglaciation of marine sectors of the Eurasian Ice Sheet, emphasising how the retreat of the Norwegian Channel and the Barents Sea ice streams led to separation of the British-Irish and Fennoscandian ice sheets at ...
