    • 3D structure and formation of hydrothermal vent complexes at the paleocene-eocene transition, the Møre basin, MID-Norwegian margin 

      Kjoberg, Sigurd; Schmiedel, Tobias; Planke, Sverre; Svensen, Henrik; Millett, John; Jerram, Dougal Alexander; Galland, Olivier; Lecomte, Isabelle; Schofield, Nick; Haug, Øystein Thorden; Helsem, Andreas (Peer reviewed; Journal article, 2017-08)
      The mid-Norwegian margin is regarded as an example of a volcanic-rifted margin, formed prior to and during, Paleogene breakup of the northeast Atlantic. The area is characterized by the presence of voluminous basaltic ...

    • A climatic trigger for the giant Troll pockmark field in the northern North Sea

      Pockmarks are seafloor craters usually formed during methane release on continental margins. However, the mechanisms behind their formation and dynamics remain elusive. Here we report detailed investigations on one of the ...

    • Geometries of doleritic intrusions in central Spitsbergen, Svalbard: an integrated study of an onshore-offshore magmatic province with implications for CO2 sequestration

      Igneous intrusions emplaced during the Early Cretaceous are well exposed in central Spitsbergen within the Permian–Jurassic sedimentary succession. The doleritic intrusions are collectively classified as the Diabasodden ...

    • Glacigenic sedimentation pulses triggered postglacial gas hydrate dissociation 

      Karstens, Jens; Haflidason, Haflidi; Becker, Lukas; Berndt, Christian; Rüpke, Lars Helmuth; Planke, Sverre; Liebetrau, Volker; Schmidt, Markus; Mienert, Jurgen (Peer reviewed; Journal article, 2018-02-12)
      Sediment cores from the south-eastern Nordic Seas simultaneously archive the variability of the Fennoscandian Ice Sheet (FIS), the British-Irish Ice Sheet (BIIS) and the regional oceanic conditions. This study aims to ...

    • Ice-stream dynamics of the SW Barents Sea revealed by high-resolution 3D seismic imaging of glacial deposits in the Hoop area 

      Bellwald, Benjamin; Planke, Sverre; Piasecka, Emilia Daria; Matar, M.A.; Andreassen, Karin (Peer reviewed; Journal article, 2018-03-01)
      Recent developments in seismic acquisition systems and seismic data visualization have contributed to improve the imaging of seismic geomorphologies over a broad range of topics. This study focuses on a new high-resolution ...

    • Impacts of seismic resolution on fault interpretation: Insights from seismic modelling 

      Faleide, Thea Sveva; Braathen, Alvar; Lecomte, Isabelle Christine; Mulrooney, Mark Joseph; Midtkandal, Ivar; Bugge, Aina J.; Planke, Sverre (Journal article; Peer reviewed, 2021)
      Seismic mapping of subsurface faults is hampered by factors such as seismic resolution, velocity control for depth conversion and human bias. Here, we explore the challenges and pitfalls related to interpreting normal ...

    • Meltwater sediment transport as the dominating process in mid-latitude trough mouth fan formation 

      Bellwald, Benjamin; Planke, Sverre; Becker, Lukas; Myklebust, Reidun (Journal article; Peer reviewed, 2020)
      Trough mouth fans comprise the largest sediment deposits along glaciated margins, and record Pleistocene climate changes on a multi-decadal time scale. Here we present a model for the formation of the North Sea Fan derived ...

    • A new high-resolution stratigraphic and palaeoenvironmental record spanning the End-Permian Mass Extinction and its aftermath in central Spitsbergen, Svalbard 

      Zuchuat, Valentin; Sleveland, Arve; Twitchett, Richard; Svensen, Henrik; Turner, Holly E; Augland, Lars Eivind; Jones, Morgan Thomas; Hammer, Øyvind; Hauksson, Bjarki; Haflidason, Haflidi; Midtkandal, Ivar; Planke, Sverre (Journal article; Peer reviewed, 2020-09-15)
      Research on the Permian-Triassic boundary (PTB) along the northern margins of Pangaea (exposed today in the Arctic region) has been heavily reliant on field observations, where data resolution was consequently determined ...

    • Northeast Atlantic breakup volcanism and consequences for Paleogene climate change – MagellanPlus Workshop report 

      Berndt, Christian; Planke, Sverre; Teagle, Damon; Huismans, Ritske; Torsvik, Trond Helge; Frieling, Joost; Jones, Morgan Thomas; Jerram, Dougal Alexander; Tegner, Christian; Faleide, Jan Inge; Coxall, Helen; Hong, Wei-Li (Peer reviewed; Journal article, 2019-12-02)
      The northeast Atlantic encompasses archetypal examples of volcanic rifted margins. Twenty-five years after the last ODP (Ocean Drilling Program) leg on these volcanic margins, the reasons for excess melting are still ...
