(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)tWave form modeling is used in a vast number of applications. Therefore, different methods have beendeveloped that exhibit different strengths and weaknesses in accuracy, stability and computational cost.The latter remains ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Melting curves of Ca-perovskite (pure CaSiO3) were determined by ab initio density functional theory, using two solid-liquid coexistence methods and two free energy approaches, in the form of thermodynamic integration and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The ab initio (ai) Gibbs ensemble (GE) Monte Carlo (MC) method coupled with Kohn–Sham density functional theory is successful in predicting the liquid–vapour equilibrium of insulating systems. Here we show that the aiGEMC ...

(Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)The sinking remnant of a surface plate crosses and interacts with multiple boundaries in Earth's interior. Here, we specifically investigate the prominent dynamic interaction of the sinking plate portion with the upper-mantle ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Doming, a superimposition of a scene-wide dome-shaped bias to the elevation data, is a classical problem in photogrammetry, especially when using the auto-calibration and bundle adjustment typical of the Structure-from-Motion ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)We defined a new global moving hot spot reference frame (GMHRF), using a comprehensive set of radiometric dates from arguably the best‐studied hot spot tracks, refined plate circuit reconstructions, a new plate polygon ...

-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2021)Glaciers distinct from the Greenland and Antarctic ice sheets are shrinking rapidly, altering regional hydrology1, raising global sea level2 and elevating natural hazards3. Yet, owing to the scarcity of constrained mass ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract Projected climate warming and wettening will have a major impact on the state of glaciers and seasonal snow in High Arctic regions. Following up on a historical simulation (1957–2018) for Svalbard, we make future ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)A strong 50–35 Ma decrease in India‐Asia convergence is generally ascribed to continent‐continent collision. However, a convergence rate increase of similar magnitude occurred between ∼65–50 Ma. An earlier increase occurred ...
-
(Master thesis / Masteroppgave, 2019)Plast i det marine miljøet er av økende bekymring på grunn av dets persistente egenskaper og ukjente effekter på dyreliv og mennesker. Mye plastavfall havner i havet hvert år, og det er forventet at denne mengden skal øke. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract Application potential and development prospect of satellite precipitation products such as Tropical Rainfall Measuring Mission (TRMM) and Global Precipitation Mission (GPM) have promising implications. ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)This paper part one is set out to lay primary observations of experimental compaction measurements to form the basis for rock physics modelling in paper part two. P‐ and S‐wave velocities and corresponding petrophysical ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The seismic oceanography method is based on extracting and stacking the low-frequency acoustic energy scattered by the ocean heterogeneity. However, a good understanding on how this acoustic wavefield is affected by physical ...
-
(Doctoral thesis / Doktoravhandling, 2020)Hydrocarbons in easily accessible areas have been explored on the Norwegian continental shelf, with much of it having been tapped out to supply the world’s energy demand. The growing consumption and demand have driven ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)The detailed record of diagnostic acritarchs from the volcanosedimentary Vallehondo and Playón formations, bracketed between Cambrian Stage 4 strata bearing the trilobite Serrodiscus and Guzhangian (Miaolingian) beds with ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Active layer probing in northern Sweden, northeast Greenland, and central Svalbard indicates active layer thickening has occurred at Circumpolar Active Layer Monitoring (CALM) sites with long‐term, continuous observations, ...
