(Doctoral thesis / Doktoravhandling, 2010)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)In this paper, a process‐based analytical derivation approach is proposed to perform a nonstationary analysis for annual runoff distribution by taking into account the information of nonstationarities in both hydrological ...
-
(Master thesis / Masteroppgave, 2005)The human influence on vegetation causes changes in the surface reflective properties. By using MODIS land cover and MODIS surface albedo products, an estimation of radiative forcing due to surface albedo changes caused ...
-
(Master thesis / Masteroppgave, 2007)Abstract Mineralogical and chemical analysis of alum shale and black shale samples were done using the XRD, XRF, sulfur chemical analysis, petrographic and scanning electron microscopy. Samples from two study areas in the ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)The rate at which global mean sea level (GMSL) rose during the 20th century is uncertain, with little consensus between various reconstructions that indicate rates of rise ranging from 1.3 to 2 mm⋅y−1. Here we present a ...
-
(Master thesis / Masteroppgave, 2007)Change in glacier extent is a good indication of climate change. Inventories for glaciated areas should therefore be made at certain intervals. For New Zealand a digitized glacial inventory including both the two main ...
-
(Doctoral thesis / Doktoravhandling, 2023)The 21st century has already seen a series of major drought events in Europe. The high costs and multiple impacts highlight the importance of a holistic understanding of drought in order to improve preparedness and mitigation. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)The international research project RECONCILE has addressed central questions regarding polar ozone depletion, with the objective to quantify some of the most relevant yet still uncertain physical and chemical processes and ...

(Master thesis / Masteroppgave, 2018)
-
(Master thesis / Hovedoppgave, 2007)An assessment of extreme hydrological low flow and drought events is of vital importance to water resources management. One way to reduce the uncertainty in the estimate of the extreme events is to use a regional dataset ...
-
(Master thesis / Masteroppgave, 2008)
-
(Master thesis / Masteroppgave, 2007)This study comprises a geological reservoir characterization of paralic sandstone deposits with a case study of the Upper Jurassic Louriñha Formation in the Lusitanian Basin, which is an Atlantic rift basin located in ...
-
(Master thesis / Masteroppgave, 2007)The Lusitanian Basin in Portugal is an Atlantic margin rift basin on the western side of the Iberian plate positioned north of Lisbon. The basin contains, among several other formations, the Upper Jurassic Louriñha Formation ...
-
(Master thesis / Masteroppgave, 2005)The aim of the present study has been to gather and handle data from a sandstone outcrop as an analogue for a hypothetical fluvial sandstone reservoir. Reservoirs generally have a limited set of data and number of data ...
-
(Doctoral thesis / Doktoravhandling, 2020)Siliciclastic sandstones constitute important reservoirs for subsurface storage of water, oil and natural gas. Knowledge of the geological processes enhancing or reducing the key reservoir properties – porosity and ...
-
(Master thesis / Masteroppgave, 2004)An attempt was made to identify the degree and main control of early diagenesis. It was evident that the more porous, channel sandstone units provided a better pathway for fluidflow and were thus subject to a greater degree ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2008)The deployment of temporary arrays of broadband seismological stations over dedicated targets is common practice. Measurement of surface wave phase velocity across a small array and its depth-inversion gives us information ...
-
(Master thesis / Masteroppgave, 2007)Rainfall induced landslides is one of the most common natural hazard worldwide. Intensive rainfall and rapid snow melting caused the two landslides in Jordalsdalen in Fjærland in Western Norway. Debris flow is a global ...
-
(Master thesis / Masteroppgave, 2007)Clouds cover about 70% of the earth. In 1983 the world first satellite program, called International Satellite Cloud Climatology Project (ISCCP), was established. ISCCP use geostationary and polar orbiting satellites to ...
-
(Master thesis / Masteroppgave, 2008)Til tross for at isskred fra breer sjelden forekommer, utgjør disse en kontinuerlig fare for menneskeliv og infrastruktur lokalisert i nærområdene. Skred fra bratte breer kan forekomme som en naturlig del av ablasjonsprosessen ...
