-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Buoyancy-driven convection in a conditionally unstable ocean is studied theoretically. Conditionally unstable conditions are related to supercooled seawater. The freezing point is depressed due to increasing pressure, and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract Despite being exposed to convective stresses for much of the Earth's history, cratonic roots appear capable of resisting mantle shearing. This tectonic stability can be attributed to the neutral density and higher ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Ordinary chondrites originate from S-type asteroids. These meteorites can be used for laboratory studies that further our understanding of the geological conditions on asteroids, including assessment of their resource ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract Forecasts of sea ice evolution in the Arctic region for several months ahead can be of considerable socioeconomic value for a diverse range of marine sectors and for local community supply logistics. However, ...

Core-mantle boundary topography and its relation to the viscosity structure of the lowermost mantle (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Two large areas of anomalously low seismic velocities are visible in all tomographic models of the lowermost mantle. Depending on the density structure of these Large Low Shear Velocity Provinces (LLSVPs), the core-mantle ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion, 2022)A new citation needs to be added to the original publication [...]
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)In recent years a vast amount of glacier surface velocity data from satellite imagery has emerged based on correlation between repeat images. Thereby, much emphasis has been put on the fast processing of large data volumes ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The Collisional Orogeny in the Scandinavian Caledonides (COSC) scientific drilling project aims to characterise the structure and orogenic processes involved in a major collisional mountain belt by multidisciplinary ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Satellite measurements of coseismic displacements are typically based on synthetic aperture radar (SAR) interferometry or amplitude tracking, or based on optical data such as from Landsat, Sentinel-2, SPOT, ASTER, very ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion; Peer reviewed, 2012)The Congo Basin is characterised by a near-circular shape, a pronounced negative free-air gravity anomaly, and a subsidence history that is slow and long-lived. The basin is often considered as an intracratonic basin, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Tabular intrusions are common features in the Earth's brittle crust. They exhibit a broad variety of shapes, ranging from thin sheet intrusions (sills, saucer-shaped sills, cone sheets), to more massive intrusions (domed ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)Calcium carbonate and cadmium-rich fluid interactions have been studied at the nano and microscale with fluid flow and static fluid conditions for three forms of CaCO3: calcite in single crystals of Iceland Spar, calcite ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)MgO makes up about 20% of the Earth’s lower mantle; hence, its rheological behaviour is important for the dynamics and evolution of the Earth. Here, we investigate the strength of twin boundaries from 0 to 120 GPa using ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)This paper presents an improved understanding of coupled hydro-thermo-mechanical (HTM) hydraulic fracturing of quasi-brittle rock using the bonded particle model (BPM) within the discrete element method (DEM). BPM has been ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Monte Carlo (MC) methods have been widely used in uncertainty analysis and parameter identification for hydrological models. The main challenge with these approaches is, however, the prohibitive number of model runs required ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Statistical downscaling is useful for managing scale and resolution problems in outputs from global climate models (GCMs) for climate change impact studies. To improve downscaling of precipitation occurrence, this study ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Continental rifted margins are often associated with widespread, thick evaporite (i.e., salt) deposits and pronounced salt tectonics. The majority of salt basins formed during the latest stages of rifting, prior to continental ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Faults in carbonate rocks show both seismic and aseismic deformation processes, leading to a wide range of slip velocities. We deformed two centimeter‐scale cores of Carrara marble at 25°C and imaged the nucleation and ...
