  • 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 / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    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 ...
  • A climatic trigger for the giant Troll pockmark field in the northern North Sea 
    Mazzini, Adriano; Svensen, Henrik; Forsberg, Carl Fredrik; Linge, Henriette; Lauritzen, Stein-Erik; Haflidason, Haflidi; Hammer, Øyvind; Planke, Sverre; Tjelta, Tor-Inge (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    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 ...
  • 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 (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Large amounts of methane are stored in continental margins as gas hydrates. They are stable under high pressure and low temperature, but react sensitively to environmental changes. Bottom water temperature and sea level ...
  • Rapid and sustained environmental responses to global warming: The Paleocene-Eocene Thermal Maximum in the eastern North Sea 
    Stokke, Ella W.; Jones, Morgan Thomas; Riber, Lars; Haflidason, Haflidi; Midtkandal, Ivar; Schultz, Bo; Svensen, Henrik (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    The Paleocene–Eocene Thermal Maximum (PETM; ∼ 55.9 Ma) was a period of rapid and sustained global warming associated with significant carbon emissions. It coincided with the North Atlantic opening and emplacement of the ...
