Anatomy of a mega-rock slide at Forkastningsfjellet, Spitsbergen and its implications for landslide hazard and risk considerations
(Peer reviewed; Journal article, 2019)Rock slope failures are a potential source of danger in polar regions. A causal connection between slope failures and climate-related glacial and deglacial processes has been inferred for the growing number of documented ... -
Bivalve beds reveal rapid changes in ocean oxygenation in the Boreal Middle Triassic – a case study from Svalbard, Norway
(Peer reviewed; Journal article, 2023)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 ... -
Detrital zircons of the vast Triassic Snadd and De Geerdalen formations, Barents Shelf, reveal temporal changes in sediment source
(Peer reviewed; Journal article, 2023)Studies of detrital-zircon age distributions from Triassic sedimentary rock successions on the Arctic Barents Shelf have resulted in different provenance interpretations. Here, we provide new U–Pb/Hf detrital-zircon data ... -
The Hambergfjellet Formation on Bjørnøya – sedimentary response to early Permian tectonics on the Stappen High
(Peer reviewed; Journal article, 2023)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 ... -
Magnetic mapping of fault zones in the Leka Ophiolite Complex, Norway
(Peer reviewed; Journal article, 2020)The island of Leka and surrounding skerries expose a complete suite of ophiolitic rocks, which are heavily faulted. Large areas consist of ultramafic rocks, which are locally hydrated and form serpentinites. Faults are ... -
Notes on Ordovician graptolites, nautiloides and trace fossils from Lånke, Central Norwegian Caledonides
(Journal article; Peer reviewed, 2020)Graptolites and trace fossils typical of deep-water environments are found on phyllitic roofing slates kept in the collections of the Stjørdal Museum Værnes, Trøndelag. The slates probably come from abandoned local quarries ... -
Permo–Triassic sedimentary fills and tectonic phases off Mid Norway: seismic investigation of the Trøndelag Platform
(Peer reviewed; Journal article, 2020)Seismic interpretation (2D and new 3D surveys) has been used to investigate sedimentary fills and timing of tectonic activity offshore Mid Norway. This study was focused on upper Permian and Lower Triassic sedimentary basin ... -
Petrology of the crystalline crust in the southwestern Barents Sea inferred from geophysical data
(Peer reviewed; Journal article, 2022)We present a new petrological model of the crystalline crust in the southwestern Barents Sea derived in a comprehensive workflow that focuses on the interpretation of gravity, magnetic and seismic data and that incorporates ... -
Quantification of time-varying groundwater flow in boreholes in fractured crystalline rock using long-term distributed temperature sensing
(Peer reviewed; Journal article, 2022)Quantification of groundwater flow is an important factor for several applications, such as water supply, boreholes for energy extraction/storage and drainage and flood prevention projects. In this study, distributed ... -
Stratigraphy and palaeosol profiles of the Upper Triassic Isfjorden Member, Svalbard
(Peer reviewed; Journal article, 2022)The Isfjorden Member forms the upper part of the De Geerdalen Formation in Svalbard and is well exposed throughout central and eastern Spitsbergen, including the island of Wilhelmøya. We examine palaeosol profiles identified ... -
Tectono-sedimentary evolution of the eastern Forlandsundet Graben, Svalbard
(Peer reviewed; Journal article, 2021)The Forlandsundet Graben, situated along the NE Atlantic continental margin in the western Svalbard archipelago in Arctic Norway, represents a unique opportunity to study a basin that evolved along an obliquely rifted ... -
The history of exploration and stratigraphy of the Early to Middle Triassic vertebrate-bearing strata of Svalbard (Sassendalen Group, Spitsbergen)
(Journal article; Peer reviewed, 2018)The palaeontology of the Lower to Middle Triassic succession in Spitsbergen has been studied for more than a century and a half. Our ability to properly interpret the evolutionary and ecological implications of the faunas ... -
You learn as long as you drill; research synthesis from the Longyearbyen CO2 Laboratory, Svalbard, Norway.
(Journal article; Peer reviewed, 2019)From 2007 to 2015, eight wells were drilled and fully cored to test the feasibility of storing CO2 emitted from the coal-fueled power plant in Longyearbyen, Svalbard. The drilling campaign identified three water-bearing ...
