(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)With its high albedo, low thermal conductivity and large water storing capacity, snow strongly modulates the surface energy and water balance, which makes it a critical factor in mid- to high-latitude and mountain en- ...
-
(Doctoral thesis / Doktoravhandling, 2019)This thesis presents a satellite-based modeling framework that can estimate how much snow was stored in the terrain. These estimates can help guide climate analysis and prediction. Accurate quantification of Earth’s snow ...
-
(Doctoral thesis / Doktoravhandling, 2019)In the contemporary world, many environmental and water resources related decisions rely upon wide range of modelling results. However, models are simplified representations of reality and their predictions are generally ...
-
(Master thesis / Masteroppgave, 2021)The snow crab, Chionoecete opilio, is an invasive species in the Barents Sea. The spread of the species has know environmental impacts on the benthic community, removing species important for biominxing. By analyzing short ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)The link between the Permian–Triassic mass extinction (252 million years ago) and the emplacement of the Siberian Traps Large Igneous Province (STLIP) was first proposed in the 1990s. However, the complex cascade of ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)The study focuses on occurrences of Ophiomorpha burrows in a transgressive–regressive succession composing the Early Paleocene Firkanten Formation deposited in paralic, prodelta to delta front conditions in the Central ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Faults are complex structures that substantially influence the mechanical behavior and hydraulic connectivity of rock formations. Therefore, studying faults is important for a variety of disciplines such as geoscience, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Remote sensing satellites provide a vast amount of data to monitor and observe Earth’s surface and events on it. To use these data efficiently in subsequent analysis and decision-making, highly automated easy-to-use tools ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)During the POLARCAT summer campaign in 2008, two episodes (2–5 July and 7–10 July 2008) occurred where low-pressure systems traveled from Siberia across the Arctic Ocean towards the North Pole. The two cyclones had extensive ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract Spreading centre jumps are a common feature of oceanic back-arc basins. Jumps are conventionally suggested to be triggered by plate velocity changes, pre-existing weaknesses, or punctuated events such as the opening ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Decades of geochronological work have shown the temporal distribution of zircon ages to be episodic on billion-year timescales and seemingly coincident with the lifecycle of supercontinents, but the physical processes ...
-
(Master thesis / Masteroppgave, 2008)The quest to unravel and better constrain the crustal architecture and related geological processes of South Atlantic margins underscores the importance of this study. This is true considering the huge economic prospect ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The Stokes drift in long baroclinic equatorial Rossby waves is investigated theoretically by using eigenfunction expansions in the vertical. These waves are non-dispersive and propagate westward along the equator. Particular ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)The equilibrium climate sensitivity of Earth is defined as the global mean surface air temperature increase that follows a doubling of atmospheric carbon dioxide. For decades, global climate models have predicted it as ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Abstract. An equilibrium simulation of Marine Isotope Stage 3 (MIS3) climate with boundary conditions characteristic of Greenland Interstadial 8 (GI-8; 38 kyr BP) is carried out with the Norwegian Earth System Model (NorESM). ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)When conducting numerical upscaling, either for a fractured or a porous medium, it is important to account for anisotropy because in general, the resulting upscaled conductivity is anisotropic. Measurements made at different ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Deep and complex geodynamic processes, including the effects of plumes, heat, plate tectonics, and local tectonics control the Earth’s surface. In the Arctic these deep processes are masked by extensive glaciations and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Non-glaciated mountain headwater catchments feature high-resolution geomorphic archives, which provide important insight into erosive processes and sediment dynamics in mountain ranges. As such the Valle de la Fueva ...

(Research report / Forskningsrapport, 1994)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Realizable CO2 storage potential for saline formations without closed lateral boundaries depends on the combined effects of physical and chemical trapping mechanisms to prevent long-term migration out of the defined storage ...
