Insights Into CO2 Storage Using the FluidFlower
(Master thesis, 2024-06-03)Carbon capture and storage (CCS) is essential for mitigating climate change. Geological sequestration stores CO2 in the subsurface, however, geological uncertainties and risks, especially leakage, present significant ... -
Maringeologisk undresøkelse an Utsira Nord havvindområdet
(Master thesis, 2024-03-05) -
Fracture characterization and monitoring of underground CO2 storage
(Master thesis, 2024-06-03) -
Evolution of ore forming fluids at the St. Jonsfjorden Au-Cu prospect, Svalbard
(Master thesis, 2024-06-03)The southern part of St. Jonsfjorden hosts Au and Cu mineralization in epigenetic quartz carbonate veins that cross-cut Ordovician-Silurian sediments and are localized along an E-W orientated thrust fault. The mineralization ... -
The Molloy Oceanic Core Complex: Petrological Studies of Mantle Rocks
(Master thesis, 2024-06-03)Seafloor spreading at ultraslow spreading rates causes uplift of the underlying crustal structure and mantle, forming oceanic core complexes (OCC). At the edge of the perennial Arctic sea ice cover, the Fram Strait forms ... -
Ice-dammed lakes and deglaciation history of the Scandinavian Ice Sheet in central Jämtland, Sweden
(Journal article; Peer reviewed, 2023)Extensive glacial lakes dammed in the Scandinavian Mountains during the retreat of the last Scandinavian Ice Sheet were first hypothesised over a century ago. Here, using high-resolution LiDAR, we report >4500 relict ... -
Symplectite and kelyphite formation during decompression of mafic granulite from Gjelsvikfjella, central Dronning Maud Land, Antarctica
(Journal article; Peer reviewed, 2023)Central Dronning Maud Land (cDML) is part of the late Mesoproterozoic Maud Belt in East Antarctica, which was metamorphosed and deformed during the Ediacaran–Cambrian Gondwana assembly. Here we study high-pressure (HP) ... -
Significance of Short-Wavelength Magnetic Anomaly Low Along the East Pacific Rise Axis, 9°50′N
(Journal article; Peer reviewed, 2023)Magnetic anomaly variations near mid-ocean ridge spreading centers are sensitive to a variety of crustal accretionary processes as well as geomagnetic field variations when the crust forms. We collected near-bottom vector ... -
Sensitivity of coastal southern African climate to changes in coastline position and associated land extent over the last glacial
(Journal article; Peer reviewed, 2023)Paleoclimatic changes in South Africa, especially around the southern Cape region, are of intense interdisciplinary interest; as this is an important area in the context of human evolution, hosting several prominent ... -
Complex fault system revealed by 3-D seismic reflection data with deep learning and fault network analysis
(Journal article; Peer reviewed, 2023)Understanding where normal faults are located is critical for an accurate assessment of seismic hazard; the successful exploration for, and production of, natural (including low-carbon) resources; and the safe subsurface ... -
Impact of Inherited Foreland Relief on Retro-Foreland Basin Architecture
(Journal article; Peer reviewed, 2023)We use a Landscape Evolution Model including flexural isostasy to investigate the influence of inherited foreland relief on the stratigraphic evolution of the retro-foreland domain during mountain building. We show models ... -
3-D induction log modelling with integral equation method and domain decomposition pre-conditioning
(Journal article; Peer reviewed, 2024)The deployment of electromagnetic (EM) induction tools while drilling is one of the standard routines for assisting the geosteering decision-making process. The conductivity distribution obtained through the inversion of ... -
Deghosting dual-component streamer data using demigration-based supervised learning
(Journal article; Peer reviewed, 2024)Ghost reflections from the free surface distort the source signature and generate notches in the seismic amplitude spectrum. For this reason, removing ghost reflections is essential to improve the bandwidth and signal-to-noise ... -
Earthquake-induced landslides in Norway
(Journal article; Peer reviewed, 2023)Norway is located in an intraplate setting with low-to-moderate seismicity. The mountainous landscape leads to a high level of landside activity throughout the country. Earthquake-induced landslides (EQILs) are common in ... -
Spatio-temporal variability in geometry and geodetic mass balance of Jostedalsbreen ice cap, Norway
(Journal article; Peer reviewed, 2023)The Jostedalsbreen ice cap is mainland Europe's largest ice cap and accommodates 20% (458 km2 in 2019) of the total glacier area of mainland Norway. Jostedalsbreen and its meltwater contribute to global sea-level rise and ... -
The West African salt-bearing rifted margin—Regional structural variability and salt tectonics between Gabon and Namibe
(Journal article; Peer reviewed, 2023)Salt-bearing rifted margins comprise some of the most structurally complex and economically important sedimentary basin settings such as the South Atlantic and the Gulf of Mexico salt basins. They are also involved with ... -
The Role of On- and Off-Axis Faults and Fissures During Eruption Cycles and Crustal Accretion at 9°50′N, East Pacific Rise
(Journal article; Peer reviewed, 2023)Fissures and faults provide insight into how plate separation is accommodated by magmatism and brittle deformation during crustal accretion. Although fissure and fault geometry can be used to quantify the spreading process ... -
Seismic Imaging of the Westward Transition From Yakutat to Pacific Subduction in Southern Alaska
(Journal article; Peer reviewed, 2023)Alaska is located at the northernmost point of the interface between the Pacific plate and the North American continent. The subduction of the Pacific plate generates arc volcanoes along the Aleutian trench, which stops ... -
The EPOS multi-disciplinary Data Portal for integrated access to solid Earth science datasets
