(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)We discuss techniques to represent groundwater flow in carbonate aquifers using the three existing modeling approaches: equivalent porous medium, conduit network, and discrete fracture network. Fractures in faulted ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)We compare geocoded heights derived from the interferometric mode (SARIn) of CryoSat to surface heights from calibration–validation sites on Devon Ice Cap and western Greenland. Comparisons are included for both the heights ...
-
(Chapter / Bokkapittel / PublishedVersion; Peer reviewed, 2022)The Scandinavian Caledonides formed during the continental collision between Baltica and Laurentia. During the collision, a complex nappe stack was thrust over the Baltican continental margin. The orogen can be subdivided ...

Revisiting equilibrium condensation and rocky planet compositions: Introducing the ECCO PLANETS code (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Context . The bulk composition of exoplanets cannot yet be directly observed. Equilibrium condensation simulations help us better understand the composition of the planets’ building blocks and their relation to the composition ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)In 1963 a series of eruptions of Mt. Agung, Indonesia, resulted in the third largest eruption of the 20th century and claimed about 1900 lives. Two eruptions of this series injected SO2 into the stratosphere, which can ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Back-arc basins in continental settings can develop into oceanic basins, when extension lasts long enough to break up the continental lithosphere and allow mantle melting that generates new oceanic crust. Often, the basement ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Our understanding of continental rifting is, in large parts, derived from the stratigraphic record. This record is, however, incomplete as it does not often capture the geomorphic and erosional signal of rifting. New 3D ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The Dead Sea Fault (DSF) is a crustal-scale continental transform fault separating the African and the Arabian plates. Neogene to Quaternary volcanic activity is well-spread in Northern Israel. Yet, the origin of the magmas ...

(Doctoral thesis / Doktoravhandling, 2015)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)Knowledge of water-surface velocities in rivers is useful for understanding a range of river processes. In cold regions, river-ice break up and the related downstream transport of ice debris is often the most important ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Abstract. The PlanetScope constellation consists of ∼150 optical cubesats that are evenly distributed like strings of pearls on two orbital planes, scanning the Earth's land surface once per day with an approximate spatial ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Globalisation and interregional exchange of people, goods, and services has boosted the importance of and reliance on all kinds of transport networks. The linear structure of road networks is especially sensitive to natural ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)While reliable drought prediction is fundamental for drought mitigation and water resources management, it is still a challenge to develop robust drought prediction models due to complex local hydro-climatic conditions and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Lack of discharge data for model calibration is challenging for flood prediction in ungauged basins. Since establishment and maintenance of a permanent discharge station is resource demanding, a possible remedy could be ...
-
(Doctoral thesis / Doktoravhandling, 2018)CO2 sequestration in geological formations is a promising technology and a crucial measure to reduce CO2 emissions across the energy system. It is an essential part of the solution for mitigating climate change caused by ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Rock walls in high mountain areas are the expression of long–term slopes response (103–105 years) to tectonics, weathering and denudation and a major source of sediment and hazard. Controls of mountain rock walls (RW) ...
-
(Doctoral thesis / Doktoravhandling, 2019)In previously glaciated mountain regions rock-slope failure processes contribute significantly to landscape development and may pose a direct or indirect threat to the population and infrastructure in inhabited areas. In ...
-
The role of subduction in the formation and evolution of continental fragments and microcontinents (Doctoral thesis / Doktoravhandling, 2020)Microcontinents are small continental pieces that have been separated from their parent continent. We often find such microcontinents in oceans that form after the breakup of a large continent (e.g. the North Atlantic, ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2018)A new natural rutile reference material is presented, suitable for U‐Pb dating and Zr‐in‐rutile thermometry by microbeam methods. U‐Pb dating of rutile R632 using laser ablation ICP‐MS with both magnetic sector field and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Context. Planet formation is sensitive to the conditions in protoplanetary disks, for which scaling laws as a function of stellar mass are known. Aims. We aim to test whether the observed population of planets around ...
