    • The Cenozoic pre-glacial tectono-sedimentary development of the western Barents Sea margin: implications for uplift and erosion of the sediment source areas 

      Lasabuda, Amando Putra Ersaid; Laberg, Jan Sverre; Knutsen, Stig-Morten; Safronova, Polina; Høgseth, Gert (Conference object; Konferansebidrag, 2017)
      <p>The Cenozoic development of the western Barents Sea continental margin is strongly related to the rifting and seafloor spreading between Norway and Greenland. The margin is characterized by a series of highs and basins that formed as part of the development of a mega-transform zone. To the north, the Spitsbergen Fold and Thrust Belt and the Eocene clinoform development in the Central Basin that ...

    • The Cenozoic pre-glacial tectono-stratigraphy and erosion estimates for the NW Barents Sea 

      Lasabuda, Amando Putra Ersaid; Laberg, Jan Sverre; Knutsen, Stig-Morten; Safronova, Polina (Conference object; Konferansebidrag, 2017-04-24)

    • Cenozoic tectonostratigraphy and pre-glacial erosion: A mass-balance study of the northwestern Barents Sea margin 

      Lasabuda, Amando Putra Ersaid; Laberg, Jan Sverre; Knutsen, Stig-Morten; Safronova, Polina (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-26)
      <p>The evolution of the northwestern Barents Sea continental margin, part of a NW-SE trending mega shear zone, has been reconstructed in order to quantify the sedimentation and erosion affecting this area during and after its formation in the Paleogene–Neogene. This development was closely related to the sea-floor opening of the Norwegian-Greenland Sea. Our study incorporated 2D seismic data, well ...

    • An Early Neogene—Early Quaternary Contourite Drift System on the SW Barents Sea Continental Margin, Norwegian Arctic 

      Rydningen, Tom Arne; Høgseth, Gert; Lasabuda, Amando Putra Ersaid; Laberg, Jan Sverre; Safronova, Polina; Forwick, Matthias (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-30)
      The onset and evolution of the middle to late Cenozoic “icehouse” world was influenced by the development of the global ocean circulation linking the Norwegian–Greenland Sea-Arctic Ocean to the Atlantic Ocean. The evolution of the early Neogene to early Quaternary Bjørnøyrenna Drift, located at the SW Barents Sea continental margin, shed new light on this important hydrological event. By analyzing ...

    • The Early to Middle Cenozoic Paleoenvironment and Erosion Estimates for the northwestern Barents Sea 

      Lasabuda, Amando Putra Ersaid; Laberg, Jan Sverre; Knutsen, Stig-Morten; Safronova, Polina (Conference object; Konferansebidrag, 2017)
      <p>The northwestern Barents Sea continental margin is a structurally complex area characterized by a series of basins and highs. It’s Cenozoic development was influenced by: 1) the formation of the Spitsbergen fold-andthrust belt towards the north and a pull-apart basin, the Vestbakken Volcanic Province, to the south, and 2) the subsequent rifting and opening of the Fram Strait, the deep-water gateway ...

    • Late Pliocene–early Pleistocene deep-sea basin sedimentation at high-latitudes: mega-scale submarine slides of the north-western Barents Sea margin prior to the shelf-edge glaciations 

      Safronova, Polina; Laberg, Jan Sverre; Andreassen, Karin; Shlykova, V.; Vorren, Tore Ola; Chernikov, S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-10-01)
      At high‐latitude continental margins, large‐scale submarine sliding has been an important process for deep‐sea sediment transfer during glacial and interglacial periods. Little is, however, known about the importance of this process prior to the arrival of the ice sheet on the continental shelf. Based on new two‐dimensional seismic data from the NW Barents Sea continental margin, this study documents ...

    • Turbidites in the Eocene of Spitsbergen: Can they tell us something about the Sørvestsnaget Basin? 

      Grundvåg, Sten-Andreas; Helland-Hansen, William; Safronova, Polina (Conference object; Konferansebidrag, 2017)
      <p>The Eocene of Spitsbergen, Svalbard, has received considerable attention in the literature because of its spectacular seismic-scale clinforms exposed along many fiords and valleys. High quality outcrops enables downdip tracing of facies belts from the proximal shelf through the shelf-edge and down-slope into the basin floor. Previous publications particularly focused on the shelf-edge to slope ...
