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 (Nature Publishing Group, 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 ...

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

Senger, Kim; Roy, Srikumar; Braathen, Alvar; Buckley, Simon John; Bælum, Karoline; Gernigon, Laurent; Mjelde, Rolf; Noormets, Riko; Ogata, Kei; Olaussen, Snorre; Planke, Sverre; Ruud, Bent Ole; Tveranger, Jan (Geological Society of Norway, 2013)

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 ...

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 (Elsevier, 2017-04)

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 ...

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 (Society of Exploration Geophysicists, 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 ...

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 (Elsevier, 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 ...
