(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 ...
-
(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 ...

-
(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 ...
-
(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 ...
-
(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 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract Glacier monitoring has been internationally coordinated for more than 125 years. Despite this long history, there is no authoritative answer to the popular question: ‘Which glaciers are the largest in the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)The equipotential figures of Earth (residual geoid), and of Mars (areoid) are characterized by pairs of elevated and pairs of depressed antipodal equatorial regions. Elevated regions of the residual geoid lie vertically ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)A need for multi-functional assessment tools evaluating trade-offs and co-benefits for various types of Nature-Based Solutions (NBS) has been increasingly identified in recent years. Methodologically, concepts for a tool ...
-
(Research report / Forskningsrapport, 2000)From May 21-27, 1999, a wide-angle seismic experiment was carried out in the Skagerrak Graben. The experiment was a combined effort of the department of Geology, University of Oslo and Geomar, Kiel (as partners in the ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)In the classical concept, a hotspot track is a line of volcanics formed as a plate moves over a stationary mantle plume. Defying this concept, intraplate volcanism in Greenland and the North Atlantic region occurred ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)At present, many studies have investigated the evolution characteristics, frequency estimation techniques, and prediction of droughts and floods, but a comprehensive understanding of the spatiotemporal evolution law and ...
