    • The Appalachian area as a tectonostratigraphic analogue for the Barents Sea shelf 

      Martins, Gustavo; Ettensohn, Frank; Knutsen, Stig-Morten (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-08)
      The US Appalachian Basin and the Arctic Norwegian and Russian Barents Sea shelf (BSS) areas are two strategic provinces for the energy industry. The Appalachian Basin is a well-studied, mature, onshore basin, whereas the offshore BSS is still considered a frontier area. This study suggests that the Appalachian Basin may be an appropriate analogue for understanding the BSS and contribute to development ...

    • Cenozoic Erosion of the Barents Sea Shelf, Norwegian Arctic: A Review 

      Lasabuda, Amando Putra Ersaid; Laberg, Jan Sverre; Knutsen, Stig-Morten; Rydningen, Tom Arne (Conference object; Konferansebidrag, 2018-12)
      The circum North Atlantic-Arctic continental margin and adjacent land areas have experienced several episodes of uplift and erosion during the Cenozoic. A series of efforts quantifying this erosion for the Barents Sea shelf, where the Arctic shelf is at its widest and deepest have been done since the early 90’s using different methods. As the seismic and well database have expanded considerably, ...

    • The Cenozoic evolution and sedimentary successions of the southwestern Eurasia Basin and the northern Svalbard/Barents Sea continental margin 

      Geissler, Wolfram H; Lasabuda, Amando Putra Ersaid; Laberg, Jan Sverre; Knutsen, Stig-Morten (Conference object; Konferansebidrag, 2017)
      <p>The geologic history of the SW Eurasian Basin and the northern Svalbard/Barents Sea continental margin started in Late Cretaceous / early Tertiary. Since about 50 Ma seafloor spreading has been active in the Eurasian Basin splitting off the Lomonosov Ridge from the northern Eurasian Shelf. Since Miocene, rifting and seafloor spreading have been also established in between NE Greenland and Svalbard, ...

    • 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 ...

    • Cenozoic uplift and erosion of the Norwegian Barents Shelf – A review 

      Lasabuda, Amando Putra Ersaid; Johansen, Nora; Laberg, Jan Sverre; Faleide, Jan Inge; Senger, Kim; Rydningen, Tom Arne; Patton, Henry; Knutsen, Stig-Morten; Hanssen, Alfred (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-23)
      Uplift and erosion are complex phenomena in terms of their governing processes, precise timing and exact magnitude. The intricate relationship between different geodynamic processes leading to uplift may increase uncertainties in estimating spatial and temporal patterns. Sediment distribution from uplifted (and eroded) topography and the corresponding paleoenvironmental reconstructions require ...

    • 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 ...

    • Early to middle Cenozoic paleoenvironment and erosion estimates of the southwestern Barents Sea: Insights from a regional mass-balance approach 

      Lasabuda, Amando Putra Ersaid; Laberg, Jan Sverre; Knutsen, Stig-Morten; Høgseth, Gert (Journal article; Tidsskriftartikkel, 2018-06-02)
      The Cenozoic pre-glacial development of the southwestern Barents Sea is discussed, with focus on the early to middle Cenozoic net erosion that was poorly constrained. From 2D and 3D seismic mapping, the western Barents Sea continental margin development shows a complex history of structural configuration of highs and basins related to the Greenland and Eurasian plate movement and subsequent seafloor ...

    • Late Cenozoic erosion estimates for the northern Barents Sea: Quantifying glacial sediment input to the Arctic Ocean 

      Lasabuda, Amando Putra Ersaid; Geissler, Wolfram H.; Laberg, Jan Sverre; Knutsen, Stig-Morten; Rydningen, Tom Arne; Berglar, Kai (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-14)
      A compilation of seismic data has been used to characterize the Neogene – Quaternary sedimentary succession of the northwestern Barents Sea continental margin to better understand the paleoenvironmental evolution and the sedimentary processes involved. The Neogene strata are dominated by contourites related to the ocean circulation established from the opening of the Fram Strait connecting the ...
