(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 ...

(Master thesis / Masteroppgave, 2022)Prognosane for global oppvarming og den særskild forsterka oppvarminga i Arktis er ømfintlege for korleis klimamodellar representerer fasen til låge skyer. Dette utgjer ei uvisse for modellane. For at is skal dannast i ...

(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 ...
-
(Master thesis / Masteroppgave, 2021)To study polar amplification (PA), two idealized energy balance models are constructed: a dry-diffusive down-gradient model (diffusion model) and a model where horizontal heat fluxes are configured in such a way as to ...
-
(Master thesis / Masteroppgave, 2021)Motivated by the possible connection between the many submarine canyons and the high bioproductivity in the Lofoten-Vesterålen (LoVe) ocean region, this study investigates the flow over an idealized continental slope with ...
-
(Master thesis / Masteroppgave, 2022)The identification and characterization of faults is an important process that provides necessary knowledge from the subsurface in geological and geophysical research. 3D seismic surveys are commonly utilized for the task ...
-
(Master thesis / Masteroppgave, 2012)Groundwater wells are often clogged by incrustation, which has a negative impact on well specific capacity. Chemical and biological incrustation formed by precipitation of minerals in the well reduces the open area of slots ...

-
(Master thesis / Masteroppgave, 2012)Wildfires are a source of major perturbations in the earth-atmosphere system. Between 1997 and 2008, an area of roughly 4 · 106 km2 has been burned each year. Among other species, wildfire aerosols consist of black carbon ...
-
(Master thesis / Masteroppgave, 2019)De senere år har flere steder i Norge blitt rammet av masseførende flommer som har gjort stor skade på infrastruktur og bebyggelse. Dette er ikke bare veldig kostbart, men utgjør også en belastning for personer som bor i ...
-
(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 ...
-
(Master thesis / Masteroppgave, 2014)The aim of this work was to compare various dip estimation methods and apply the best of them to identify the dip of seismic interference noise (SI) in the shot domain. Four dip estimation methods were considered: correlation ...
