(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)International cooperation in seismology emerged rapidly at the beginning of the 20th century following the successful recording of earthquakes at great distances. The International Seismological Association (ISA) founded ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Ice aprons are poorly studied and not well-defined thin ice bodies adhering to high altitude steep rock faces, but are present in most Alpine-type high mountain environments worldwide. This study aims to precisely define ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract Ice aprons are defined as very small ice bodies covering steep rock slopes. They have only been the subject of increased scientific interest for a few years, despite the fact that they are a condition for ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract. Ground-penetrating radar (GPR) is widely used for determining mountain glacier thickness. However, this method provides thickness data only along the acquisition lines, and therefore interpolation has to be made ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)We use ice flow modelling to simulate the englacial stratigraphy of Blåskimen Island, an ice rise in Dronning Maud Land and elucidate the evolution of this data-sparse region. We apply a thermo-mechanically coupled Elmer/Ice ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The extensive lava piles of Iceland contain a unique record of geomagnetic field variations spanning the past ~ 16 Ma. Since the 1950s, palaeomagnetic data have been obtained from over 9400 Icelandic lavas. We have compiled ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Iceland’s periglacial realm is one of the most dynamic on the planet, with active geomorphologicalprocesses and high weathering rates of young bedrock resulting in high sediment yields and ongoingmass movement. Permafrost ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Using sparsely glaciated southern Norway as a case study, we assess the potential and limitations of ICESat laser altimetry for analysing regional glacier elevation change in rough mountain terrain. Differences between ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Here we present results of a workshop designed to bring together stakeholders from different states of the Indian side of the Himalayan arc and an international group of climate scientists in order to discuss how climate ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The global distribution of vegetation is largely determined by climatic conditions and feeds back into the climate system. To predict future vegetation changes in response to climate change, it is crucial to identify and ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Voluminous igneous complexes are commonly present in sedimentary basins on volcanic rifted margins, and they represent a challenge for petroleum explorationists. A 2500 km2 industry-standard 3D seismic cube has recently ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract The new mineral, illoqite-(Ce), with the ideal formula Na 2 NaBaCeZnSi 6 O 17 , has been discovered in the Taseq Slope, Ilímaussaq Alkaline Complex, Southern Greenland. Illoqite-(Ce) occurs in a hyperalkaline ...
-
(Doctoral thesis / Doktoravhandling, 2022)Nanoscale interactions at mineral-fluid interfaces are important for processes occurring at the Earth's crust. Mineral dissolution occurs when a mineral is in contact with a fluid over time and can be observed by a change ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Strain localisation structures, such as shear fractures and compaction bands, are of importance due to their influence on permeability and therefore outgassing, a factor thought to influence eruptive style. In this study, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Distributed and semi-distributed hydrological modeling approaches commonly involve the discretization of a catchment into several modeling elements. Although some modeling studies were conducted using triangulated irregular ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Documenting year-to-year variations in carbon storage potential in terrestrial ecosystems is crucial for the determination of carbon dioxide (CO2) emissions. However, the magnitude, pattern, and inner biomass partitioning ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Climate change is expected to alter European floods and associated economic losses in various ways. Here we investigate the impact of precipitation change on European average winter and summer financial losses due to ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Fault throw gradients create transverse folding, and this can influence accommodation creation and sedimentary routing and infill patterns in extensional half-graben basin. The Fanja half-graben basin (Oman) offers an ...
