    • Deep-time Arctic climate archives: high-resolution coring of Svalbard's sedimentary record – SVALCLIME, a workshop report 

      Senger, Kim; Kulhanek, Denise; Jones, Morgan T.; Smyrak-Sikora, Aleksandra; Planke, Sverre; Zuchuat, Valentin; foster, William J.; Grundvåg, Sten-Andreas; Lorenz, Henning; Ruhl, Micha; Sliwinska, Kasia K.; Vickers, Madeleine L.; Xu, Weimu (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-26)
      ​​​​​​​We held the MagellanPlus workshop SVALCLIME “Deep-time Arctic climate archives: high-resolution coring of Svalbard's sedimentary record”, from 18 to 21 October​​​​​​​ 2022 in Longyearbyen, to discuss scientific drilling of the unique high-resolution climate archives of Neoproterozoic to Paleogene age present in the sedimentary record of Svalbard. Svalbard is globally unique in that it facilitates ...

    • 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 ...

    • Petroleum, coal and research drilling onshore Svalbard: a historical perspective 

      Senger, Kim; Brugmans, Peter; Grundvåg, Sten-Andreas; Jochmann, Malte Michel; Nøttvedt, Arvid; Olaussen, Snorre; Skotte, Asbjørn; Smyrak-Sikora, Aleksandra (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-05)
      The beginning of the Norwegian oil industry is often attributed to the first exploration drilling in the North Sea in 1966, the first discovery in 1967 and the discovery of the supergiant Ekofisk field in 1969. However, petroleum exploration already started onshore Svalbard in 1960 with three mapping groups from Caltex and exploration efforts by the Dutch company Bataaffse (Shell) and the Norwegian ...

    • Seeing beyond the outcrop: Integration of ground-penetrating radar with digital outcrop models of a paleokarst system 

      Janocha, Julian; Smyrak-Sikora, Aleksandra; Senger, Kim; Birchall, Thomas (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-25)
      Paleokarst breccias are a common feature of sedimentary rift basins. The Billefjorden Trough in the High Arctic archipelago of Svalbard is an example of such a rift. Here the Carboniferous stratigraphy exhibits intervals of paleokarst breccias formed by gypsum dissolution. In this study we integrate digital outcrop models (DOMs) with a 2D ground penetrating radar (GPR) survey to extrapolate external ...

    • 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 ...

    • Teaching with digital geology in the high Arctic: opportunities and challenges 

      Senger, Kim; Betlem, Peter; Grundvåg, Sten-Andreas; Horota, Rafael Kenji; Buckley, Simon John; Smyrak-Sikora, Aleksandra; Jochmann, Malte Michel; Birchall, Thomas; Janocha, Julian; Ogata, Kei; Kuckero, Lilith; Johannessen, Rakul Maria; Lecomte, Isabelle Christine; Cohen, Sarah M.; Olaussen, Snorre (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-28)
      <p>The Covid-19 pandemic occurred at a time of major revolution in the geosciences – the era of digital geology. Digital outcrop models (DOMs) acquired from consumer drones, processed using user-friendly photogrammetric software and shared with the wider audience through online platforms are a cornerstone of this digital geological revolution. Integration of DOMs with other geoscientific data, such ...
