      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, ...

    • Cenozoic tectonosedimentary development and erosion estimates for the Barents Sea continental margin, Norwegian Arctic 

      Lasabuda, Amando Putra Ersaid (Doctoral thesis; Doktorgradsavhandling, 2018-04-26)
      The Barents Sea shelf has been experienced extensive uplift and erosion in the Cenozoic. However, the pre-glacial erosion has been so far less constrained in comparison to the glacial erosion. This paper aims to better understand the early–middle Cenozoic erosion in the western Barents Sea and the late Cenozoic erosion in the northern Barents Sea by using the mass-balance approach. The study utilizes ...

      <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 ...

      Staupe-Delgado, Reidar; Rubin, Olivier (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-12)
      In this article, we set out to reconcile a general conceptualization of disaster temporalities by drawing on the epitome example of a creeping disaster, namely famine. Our argument is driven by the recognition that slowly manifesting disaster impacts pose distinct challenges for decision makers and researchers while there is a tendency for the disaster literature to overlook the role of disaster ...
    • The challenges experts face during creeping crises: the curse of complacency 

      Zaman, Ahmad Wesal; Rubin, Olivier; Staupe, Reidar (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-05)
      The policy literature has generally conceptualised crises as urgent public threats with clearly demarcated ‘focusing events’. Consequently, most studies have identified the main challenges faced by expert agencies involved in evidence-based policymaking as managing uncertainty, time pressure and communication. However, less focus has been devoted to analysing the concrete challenges faced by expert ...
