    • Deep-water sand transfer by hyperpycnal flows, the Eocene of Spitsbergen, Arctic Norway 

      Grundvåg, Sten-Andreas; Helland-Hansen, William; Johannessen, Erik P.; Eggenhuisen, Joris T.; Pohl, Florian; Spychala, Yvonne T. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-11)
      Flood-generated hyperpycnal flows are dense, sediment-laden, turbulent flows that can form long-lived, bottom-hugging turbidity currents, which undoubtedly transport large volumes of fine-grained sediments into the ocean. However, their ability in transferring sand into deep-water basins is debated. This study presents sedimentological evidence of sandy hyperpycnal flow deposits (hyperpycnites) in ...

    • Depositional environments and source rock potential of some Upper Palaeozoic (Devonian) coals on Bjørnøya, Western Barents shelf 

      Janocha, Julian; Wesenlund, Fredrik; Thießen, Olaf; Grundvåg, Sten-Andreas; Koehl, Jean-Baptiste Philippe; Johannessen, Erik P. (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-02-27)
      Upper Palaeozoic strata are potential sources for hydrocarbon plays on the Norwegian Barents Shelf. The island of Bjørnøya (Bear Island) is located on the western margin of the Barents Shelf and represents an exposed part of the Stappen High, which makes it an excellent location to investigate the source rock potential of this succession. Here, we investigate the organic geochemical composition and ...

    • The Svalbard Carboniferous to Cenozoic Composite Tectono-Stratigraphic Element 

      Olaussen, Snorre; Grundvåg, Sten-Andreas; Senger, Kim; Anell, Ingrid; Betlem, Peter; Birchall, Thomas; Braathen, Alvar; Dallmann, Winfried Kurt; Jochmann, Malte Michel; Johannessen, Erik P.; Lord, Gareth Steven; Mørk, Atle; Osmundsen, Per Terje; Smyrak-Sikora, Aleksandra; Stemmerik, Lars (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-26)
      The Svalbard Composite Tectono-Stratigraphic Element is located on the north-western corner of the Barents Shelf and comprises a Carboniferous to Pleistocene sedimentary succession. Due to Cenozoic uplift the succession is subaerially exposed in the Svalbard archipelago. The oldest parts of the succession consist of Carboniferous to Permian mixed siliciclastic, carbonate and evaporite and spiculitic ...

    • Svalbard Composite Tectono-Sedimentary Element, Barents Sea 

      Olaussen, Snorre; Grundvåg, Sten-Andreas; Senger, Kim; Anell, Ingrid; Betlem, Peter; Birchall, Thomas; Braathen, Alvar; Dallmann, Winfried Kurt; Jochmann, Malte Michel; Johannessen, Erik P.; Lord, Gareth Steven; Mørk, Atle; Osmundsen, Per Terje; Smyrak-Sikora, Aleksandra; Stemmerik, Lars (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-06)
      The Svalbard Composite Tectono-Sedimentary Element (SCTSE) is located on the northwestern corner of the Barents Shelf and comprises a Carboniferous–Pleistocene sedimentary succession. Due to Cenozoic uplift, the succession is subaerially exposed in the Svalbard archipelago. The oldest parts of the succession consist of Carboniferous–Permian mixed siliciclastic, carbonate and evaporite, and spiculitic ...
