(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Only few countries operate systematically national and regional forecasting services for rainfall-induced landslides (i.e., debris flows, debris avalanches and shallow slides), among them Norway and Italy. In Norway, the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Five different parameterizations of Langmuir turbulence (LT) effect are investigated in a realistic model of the North Atlantic and Arctic using realistic wave forcing from a global wave hindcast. The parameterizations ...
-
(Master thesis / Hovedoppgave, 2003)The use of petroleum inclusions in petroleum and reservoir geology is a relative new tool utilized to get a better understanding of petroleum generation and migration, paleo-fluid distribution in traps, and the organic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)We evaluate how precipitation forcing data used in glacier mass balance models characterize snow accumulation events on synoptic timescales for two glaciers in north-western Svalbard (Kongsvegen and Holtedahlfonna). Using ...
-
(Master thesis / Masteroppgave, 2020)The tropical tropopause layer TTL acts as the gateway for water vapor and other chemical tracers to the stratosphere, and is important for the chemical composition and radiative balance. In this thesis, two reanalyses from ...
-
Comparison of three recent discrete stochastic inversion methods and influence of the prior choice (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Groundwater flow depends on subsurface heterogeneity, which often calls for categorical fields to represent different geological facies. The knowledge about subsurface is however limited and often provided indirectly by ...
-
(Master thesis / Masteroppgave, 2016)The frequency content of seismic data is changing with propagation depth due to intrinsic absorption. This implies that the higher frequencies are highly attenuated, thus leading to a loss in resolution of the seismic ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)In the continental crust, faults may accommodate deformation through aseismic creep, slow slip events, or seismic slips that produce dynamic damage, or a combination of these endmembers. A variety of parameters controls ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Rifted margins mark a transition from continents to oceans and contain in their architecture a record of their rift history. Recent investigations of rift architecture have suggested that multiphase deformation of the crust ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)As the Arctic warms, vegetation is responding, and satellite measures indicate widespread greening at high latitudes. This ‘greening of the Arctic’ is among the world’s most important large-scale ecological responses to ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Unconformities, by definition, correspond to erosional or nondepositional surfaces, which separate older strata below, from younger rocks above, encapsulating significant time gaps. However, recent studies have highlighted ...
-
(Master thesis / Masteroppgave, 2014)The abundance of specific clay minerals have been used to reconstruct the origin of the Kilwa Group clays, and to determine the relative changes in diagenesis, weathering and climate conditions. Late Cretaceous to Early ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2023)Compound hydrometeorological extremes have been widely examined under climate change, they have significant impacts on ecological and societal well-being. This study sheds light on a new category compound of contrasting ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Under the background of climate variability and anthropogenic stresses, changes of the runoff and sediment processes have drawn increasing concerns during the past decades. Analyzing the evolution characteristics and causes ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)The inherent regularities of hydrological processes will not be stationary under the changing environment, making the evaluation of hydrological characteristics and trend forecasting face great uncertainty. Based on the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)As organisms are adapted to their environments, assemblages of taxa can be used to describe environments in the present and in the past. Here, we use a data mining method, namely redescription mining, to discover and analyze ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Large-scale concentric structures are enigmatic geological features observed on the Earth surface and on other planetary bodies. Their formation has been attributed to several processes. Here we describe for the first time ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Arc-continent collision, followed by subduction polarity flip, occurs during closure of oceanic basins and contributes to the growth of continental crust. Such a setting may lead to a highly unusual association of ultrapotassic ...
