• Blue mussels in western Norway have vanished where in reach of crawling predators 

      Meister, Nadja; Langbehn, Tom; Varpe, Øystein; Jørgensen, Christian (Journal article; Peer reviewed, 2023)
      Blue mussels (Mytilus spp.) are declining around the world. In western Norway, they have widely disappeared from rocky shores but still thrive on floating structures. Other refugia are cracks in rocks, exposed sites, and ...
    • Changing provenance and stratigraphic signatures across the Triassic–Jurassic boundary in eastern Spitsbergen and the subsurface Barents Sea 

      Klausen, Tore Grane; Rismyhr, Bjarte; Müller, Reidar; Olaussen, Snorre (Journal article; Peer reviewed, 2022)
      A change to more sandstone dominated deposits and increasing condensation across the Triassic–Jurassic boundary is generally associated with improved reservoir quality in the Barents Sea. However, spatial and temporal ...
    • Climate and societal impacts in Scandinavia following the 536 and 540 CE volcanic double event 

      Van Dijk, Evelien; Gundersen, Ingar Mørkestøl; de Bode, Anna; Høeg, Helge Irgens; Loftsgarden, Kjetil; Iversen, Frode; Timmreck, Claudia; Jungclaus, Johann; Krüger, Kirstin (Journal article; Peer reviewed, 2023)
      In the Northern Hemisphere, the mid-6th century was one of the coldest periods of the last 2000 years, as indicated by both proxy records and Earth System Model (ESM) simulations. This cold period was initiated by volcanic ...
    • Fast robust optimization using bias correction applied to the mean model 

      Wang, Lingya; Oliver, Dean (Peer reviewed; Journal article, 2021)
      Ensemble methods are remarkably powerful for quantifying geological uncertainty. However, the use of the ensemble of reservoir models for robust optimization (RO) can be computationally demanding. The straightforward ...
    • Geocellular rendering of cave surveys in paleokarst reservoir models 

      Lønøy, Bjarte; Tveranger, Jan; Pennos, Christos; Whitaker, Fiona; Lauritzen, Stein-Erik (Journal article; Peer reviewed, 2020)
      Infilled and collapsed cave systems are an important component of many paleokarst reservoirs. Incorporating these features into industrial reservoir models commonly relies on geostatistical modelling methods that often ...
    • Iterative solvers for Biot model under small and large deformation 

      Borregales Reveron, Manuel Antonio; Kumar, Kundan; Nordbotten, Jan Martin; Radu, Florin Adrian (Journal article; Peer reviewed, 2021)
      We consider L-scheme and Newton-based solvers for Biot model under large deformation. The mechanical deformation follows the Saint Venant-Kirchoff constitutive law. Furthermore, the fluid compressibility is assumed to be ...
    • Riverine impact on future projections of marine primary production and carbon uptake 

      Gao, Shuang; Schwinger, Jörg; Tjiputra, Jerry; Bethke, Ingo; Hartmann, Jens; Mayorga, Emilio; Heinze, Christoph (Journal article; Peer reviewed, 2023)
      Riverine transport of nutrients and carbon from inland waters to the coastal and finally the open ocean alters marine primary production (PP) and carbon (C) uptake regionally and globally. So far, this process has not been ...
