    • Bivalve beds reveal rapid changes in ocean oxygenation in the Boreal Middle Triassic – a case study from Svalbard, Norway 

      Engelschiøn, Victoria Sjøholt; Bernhardsen, Sofie; Wesenlund, Fredrik; Hammer, Øyvind; Hurum, Jørn Harald; Mørk, Atle (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-17)
      A fossil-rich interval in the organic-rich marine black mudstone of the Middle Triassic Botneheia Formation on eastern Svalbard was logged in high-resolution on an extremely well exposed section with emphasis on bivalve beds, taphonomic features, trace fossils and oxygenation proxies. The size distribution, fragmentation, articulation and orientation of three bivalve beds of the epifaunal flat ...

    • Digitising Svalbard’s geology: the Festningen digital outcrop model 

      Senger, Kim; Betlem, Peter; Birchall, Thomas; Gonzaga Jr., Luis; Grundvåg, Sten-Andreas; Horota, Rafael Kenji; Laake, Andreas; Kuckero, Lilith; Mørk, Atle; Planke, Sverre; Rodes, Nil; Smyrak-Sikora, Aleksandra (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-10)
      The renowned Festningen section in the outer part of Isfjorden, western Spitsbergen, offers a c. 7 km-long nearly continuous stratigraphic section of Lower Carboniferous to Cenozoic strata, spanning nearly 300 million years of geological history. Tectonic deformation associated with the Paleogene West-Spitsbergen-Fold-and-Thrust belt tilted the strata to near-vertical, allowing easy access to the ...

    • The Hambergfjellet Formation on Bjørnøya – sedimentary response to early Permian tectonics on the Stappen High 

      Grundvåg, Sten-Andreas; Strand, Mathias; Paulsen, Christian Oen; Simonsen, Bjørn; Røstad, Jostein; Mørk, Atle; Mørk, Mai Britt Engeness (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-14)
      On Bjørnøya, the exhumed crest of the Stappen High, the lower Permian (Cisuralian) Hambergfjellet Formation represents the only exposed part of the Bjarmeland Group carbonate platform, which occurs widely elsewhere in the subsurface of the Barents Shelf. A complex stratigraphic architecture has earlier been noted for the Hambergfjellet Formation and thickness estimates range from c. 50 to more than ...

    • 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 ...

    • You learn as long as you drill; research synthesis from the Longyearbyen CO2 Laboratory, Svalbard, Norway 

      Olaussen, Snorre; Senger, Kim; Braathen, Alvar; Grundvåg, Sten-Andreas; Mørk, Atle (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-21)
      From 2007 to 2015, eight wells were drilled and fully cored to test the feasibility of storing CO<sub>2</sub> emitted from the coal-fueled power plant in Longyearbyen, Svalbard. The drilling campaign identified three water-bearing sandstone aquifers; i) a lower aquifer in Upper Triassic strata; ii) a middle aquifer in Upper Triassic to Middle Jurassic; and iii) an upper aquifer in Lower Cretaceous ...
