Abstract The Palaeocene–Eocene Thermal Maximum (PETM) was a global warming event of 5–6 °C around 56 million years ago caused by input carbon into the ocean and atmosphere. Hydrothermal venting greenhouse gases produced in contact aureoles surrounding magmatic intrusions North Atlantic Igneous Province have been proposed to play key role PETM carbon-cycle perturbation, but precise timing, magnitude climatic impact such remains uncertain. Here we present seismic data results five-borehole...
The discipline of structural geology is taking an advantage compiling observations from multiple field sites to comprehend the bigger picture and constrain region's geological evolution. In this study we demonstrate how integration a range geospatial digital data sets that relate Paleogene fault thrust belt exposed in high Arctic Archipelago Svalbard, used teaching bachelor-level courses at University Centre Svalbard. This event led formation West Spitsbergen Fold Thrust Belt its associated...
Geological carbon capture and storage (CCS) is a critical technology for mitigating greenhouse gas emissions, but the risk of leakage remains significant concern. Fault fracture networks across sealing intervals are potential pathways CO2 to escape from reservoirs, necessitating accurate assessment their permeability connectivity. Our study presents an integrated approach modelling geological in fault zones, combining single stress-permeability laboratory measurements with detailed outcrop...
The high Arctic is a remote place, where geoscientific research and teaching require expensive logistically demanding expeditions to make use of the short field seasons. absence vegetation facilitates modern photogrammetric techniques for cost-effective generation high-resolution digital outcrop models (DOMs). These georeferenced can be used in pre-fieldwork activities help prepare traditional geological fieldwork, during fieldwork record observations, post-fieldwork conduct quantitative...
Abstract Digital outcrop models (DOMs) have revolutionized the way twenty-first century geoscientists work. DOMs are georeferenced three-dimensional (3-D) digital representations of outcrops that facilitate quantitative work on at various scales. Outcrop digitalization has been traditionally conducted using laser scanners, but in past decade, it seen an exponential growth because efficient and consumer-friendly structure-from-motion (SfM) algorithms concurrent with rapid development...
Abstract. The Covid-19 pandemic occurred at a time of major revolution in the geosciences – era digital geology. Digital outcrop models (DOMs) acquired from consumer drones, processed using user-friendly photogrammetric software and shared with wider audience through online platforms are cornerstone this geological revolution. Integration DOMs other geoscientific data, such as maps, satellite imagery, terrain models, geophysical data field observations, strengthens their application both...
Abstract. Methane release from beneath lowland permafrost represents an important uncertainty in the Arctic greenhouse gas budget. Our current knowledge is arguably best developed settings where being inundated by rising sea level, which means much of methane oxidised water column before it reaches atmosphere. Here we provide a different process perspective that appropriate for fjord valleys local deglaciation causes isostatic uplift to out pace level. We describe how induces aggradation...
Abstract The Svalbard Composite Tectono-Sedimentary Element (SCTSE) is located on the northwestern corner of Barents Shelf and comprises a Carboniferous–Pleistocene sedimentary succession. Due to Cenozoic uplift, succession subaerially exposed in archipelago. oldest parts consist Carboniferous–Permian mixed siliciclastic, carbonate evaporite, spiculitic sediments that developed during multiple phases extension. majority Mesozoic composed siliciclastic deposits formed sag basins continental...
Abstract. Sedimentary rocks can provide information about the Earth paleoenvironment and are studied extensively to understand causes consequences of global climate changes in deep time. They facilitate long-time perspectives that constrain models analogues for how systems may respond to, recover from, intervals profound environmental change, including projected anthropogenic change. The Norwegian Svalbard archipelago offers an extensive Phanerozoic stratigraphic record reflects geological...
Abstract Gravity data provide constraints on lateral subsurface density variations and thus crucial insights into the geological evolution of region. Previously, gravity from Norwegian Arctic archipelago Svalbard comprised an onshore regional database with coarse station spacing 2–20 km, offshore profiles acquired in some fjords, airborne gravity, satellite altimetry. The sparse point‐based coverage hampered direct integration seismic late 1980s early 1990s. In April 2022, we at 260 new...
Abstract. Together with our students, we co-created two open-access geoscientific course modules using the Jupyter Book environment. We also assessed environment, integrated GitHub to facilitate versioning, for its suitability co-creation and open learning. The implemented an online collection of videos, animations, code snippets, slides, interactive material complement main text in a diverse learning environment that is free all. modules' topics included acquisition unoccupied aerial...
The Miocene epoch on Svalbard is characterized by volcanic activity and tectonic uplift, but the causes relationship between these two processes remain debated. evidence of coeval basaltic magmatism has probably affected a large area including Svalbard. Seidfjellet Formation, series lava flows, represents unique late subaerial magmatic event (5–10 Ma) in northwestern Spitsbergen. These covering more than 200 km2, are exposed top numerous mountains Andrée Land overlying...
Offshore basalt flow sequences represent potential permanent CO2 sequestration sites along volcanic rifted margins. The International Ocean Discovery Program (IODP) Expedition 396 drilled six basement on the Vøring margin in 2021, recovering more than 350 m of basaltic cores and 15 granite cores. have been extensively analyzed following IODP shipboard procedures (e.g., velocity, density, porosity, magnetic susceptibility measurements). In addition, shore-based petrographic,...
Low-angle normal faults (LANFs), characterized by dips of less than 30°, are frequently observed in rifted margins. Despite extensive research, the mechanical processes governing LANFs remain poorly constrained, raising critical questions about angle at which they initiate, their evolution during extension, three-dimensional geometry, and related deformation hanging-wall footwall. Addressing these issues is essential for understanding extensional such tectonic settings, including...
Marine controlled source electromagnetic (CSEM) data have been utilized in the past decade during petroleum exploration of Barents Shelf, particularly for de-risking highly porous sandstone reservoirs Upper Triassic to Middle Jurassic Realgrunnen Subgroup. In this contribution we compare resistivity response from CSEM wireline logs both water- and hydrocarbon-bearing wells. We show that there is a very good match between these types data, when are shallow. however, only provide information...
Svalbard is a High Arctic Archipelago at 74–81°N and 15–35 °E under the sovereignty of Norway. All settlements in Svalbard, including capital Longyearbyen (population 2400), currently have isolated energy systems with coal or diesel as main source. Geothermal considered possible alternative for electricity production, heat source district heating harnessed cooling using geothermal pump installations. In this contribution we present until now fragmented data sets relevant to characterize...
Abstract In continuous permafrost regions, pathways for transport of sub‐permafrost groundwater to the surface sometimes perforate frozen ground and result in formation a pingo. Explanations offered locations such have so far included hydraulically conductive geological units faults. On Svalbard, several pingos locate at valley flanks where these controls are apparently lacking. Intrigued by this observation, we elucidated setting around pingo with electrical resistivity tomography. The...
Abstract While basaltic volcanism is dominant during rifting and continental breakup, felsic magmatism may be a significant component of some rift margins. During International Ocean Discovery Program (IODP) Expedition 396 on the margin Norway, graphite‐garnet‐cordierite bearing dacitic unit (the Mimir dacite) was recovered in two holes within early Eocene sediments High (Site U1570), marginal high Vøring Transform Margin. Here, we present comprehensive textural, petrological, geochemical...
