(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Energetic particle precipitation is one of the main processes by which the sun influences atmospheric composition and structure. The polar middle atmosphere is chemically disturbed by the precipitation-induced production ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Late Ediacaran opening of the Iapetus Ocean is typically considered to reflect separation of Baltica and Laurentia during final breakup of the Rodinia supercontinent, with subsequent closure during the Caledonian Orogeny. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract. The climate of the Northern Hemisphere (NH) in the mid-6th century was one of the coldest during the last 2 millennia based on multiple paleo-proxies. While the onset of this cold period can be clearly connected ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract Observations show increases in river discharge to the Arctic Ocean especially in winter over the last decades but the physical mechanisms driving these changes are not yet fully understood. We hypothesize ...
-
(Master thesis / Masteroppgave, 2012)In the Bahi-Manyoni basin in Central Tanzania the geology and climate of the area are the main factors influencing the water chemistry and quality. Most water samples are saturated with respect to quarts, dolomite, calcite, ...

Water resources assessment of glacierized Himalayan basin under changing climate Case study-The Upper Beas Basin (up to Thalout),IndiaRestricted Access (Master thesis / Masteroppgave, 2015)The aim of this study was to evaluate the performance of different variants of the parsimonious large-scale GSM-WASMOD glacio-hydrological model in quantifying the water resources of the Upper Beas basin under past and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract The mean drift in a porous seabed caused by long surface waves in the overlying fluid is investigated theoretically. We use a Lagrangian formulation for the fluid and the porous bed. For the wave field we assume ...

(Research report / Forskningsrapport, 1984)
-
(Master thesis / Hovedoppgave, 2005)The situation in the Middle East has over the last centuries received much attention from the international community. There is a long history of disputes over natural resources like oil and land in the Middle East, and ...
-
(Master thesis / Masteroppgave, 2010)We consider the relative importance of wind and currents in the determination of optimal routes, commonly referred to as weather routing, for sailboats. Weather routing for sailboats is the process of finding the fastest ...
-
(Master thesis / Masteroppgave, 2013)This study describes weathering pattern in saprolites of the Vånga Granite along various profiles at Ivö Klack, Scania (southern Sweden) and provides a model against which paleo-chemical weathering of ancient profiles (e.g. ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Saprock-saprolite associations were studied by field and laboratory methods (optical microscopy, X-ray powder diffraction, scanning electron microscopy, electron microprobe) in order to describe regolith development in the ...

(Master thesis / Masteroppgave, 2015)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Contemporary optical remote sensing satellites or constellations of satellites can acquire imagery at sub-weekly or even daily timescales. These systems have the potential to facilitate intra-seasonal, short-term surface ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The discipline of structural geology is taking an advantage of compiling observations from multiple field sites to comprehend the bigger picture and constrain the region's geological evolution. In this study we demonstrate ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Questions: Field-based ecosystem mapping is prone to observer bias, typically resulting in a mismatch between maps made by different mappers, that is, inconsistency. Experimental studies testing the influence of site, ...
-
(Doctoral thesis / Doktoravhandling, 2021)This thesis provides insights into fieldwork practices in Higher Education Earth Science and how these practices influence students’ senses of belonging and their negotiations of geoscience identities. The work illustrates ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract A recent study (Millan and others, 2022 a , Nature Geoscience 15(2), 124–129) claims that ice volume contained in all glaciers outside the ice sheets and its potential contribution to sea level is 20% less than ...
