(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)We consider the distribution and level of local vertical mixing inside of the Drøbak Sill in the Oslofjord, Norway. The work is motivated by observations of long periods (∼years) of hypoxic or even anoxic conditions in the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The Lofoten Basin in the eastern Nordic Seas plays a central role in modifying the warm Atlantic Water inflow toward the Arctic Ocean. Here, the Atlantic Water experiences increased residence times, cooling, and substantial ...

(Research report / Forskningsrapport, 2006)An infrared heating lamp has been used as the driving force in laboratory experiments simulating the thermohaline circulation of the world ocean. The radiative energy from the lamp absorbed at different depths in the ...
-
(Master thesis / Masteroppgave, 2010)A total of 21 core samples from well 2/7-26S of the Embla Field and One reference sample from Oseberg have been geochemically studied. In the studied well the Embla Field consists of two main reservoir units, the Upper and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The lost momentum in spatially damped internal Kelvin waves reappears as Eulerian mean currents through the action of the nonlinear wave-wave interaction terms. A novel expression is derived for the steady balance between ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract: The Pre-Caledonian margin of Baltica has been outlined as a tapering wedge with increas- ing magmatism towards the ocean–continent transition. It is, however, well known that margins are complex, with different ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The mean drift in spatially damped long gravity waves at the boundary between two layers of immiscible viscous fluids is investigated theoretically by applying a Lagrangian description of motion. The focus of the paper is ...
-
(Doctoral thesis / Doktoravhandling, 2018)Vulkansk aske i atmosfæren medfører en risiko for flytrafikk, såvel som helserisiko for samfunnet og kan påvirke klimaet. I denne avhandlingen er det undersøkt ulike typer aske, lokalisering, konsentrasjon, og spesielt ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Large perturbations in the global carbon cycle recorded as carbon-isotope (δ13C) excursions (CIEs) in both organic carbon and carbonate records have been linked to volcanism during the emplacement of Large Igneous Provinces ...
-
(Master thesis / Masteroppgave, 2010)Long, non-dispersive coastal wind-generated internal waves in the Hardangerfjord is investigated based on hydrographic data at the coast and current and temperature measurements in the fjord. The aim of the present work ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Understanding the approach to faulting in continental rocks is critical for identifying processes leading to fracturing in geomaterials and the preparation process of large earthquakes. In situ dynamic X-ray imaging and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)To examine the impact of preexisting weaknesses on fracture coalescence during volcanic edifice deformation, we triaxially compressed Mount Etna basalt while acquiring in situ dynamic X‐ray microtomograms and calculated ...
-
(Master thesis / Hovedoppgave, 2005)This thesis looks into features of the volume flux in the narrow Drøbak strait, and water level changes in the inner Oslofjord. Earlier measurements suggest that the volum flux in the east course of the strait, calculated ...
-
(Doctoral thesis / Doktoravhandling, 2022)Coherent swirling bodies of water; mesoscale (10-100 km) vortices, are an essential part of the general ocean circulation. Mesoscale vortices are abundant everywhere in the World Ocean and are vital in upholding equilibrium ...
-
(Master thesis / Masteroppgave, 2013)Two wide angle 3-Compnent Ocean Bottom Seismometer (OBS) profiles along with associated Land-Stations acquired during 2003 under the EUROMARGINS Program were analyzed during this M.Sc. Thesis. These profiles are named as ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)This work shows an alternative and efficient method to estimate Vs30 values and depth to basement data. The Vs30 value is the most important attribute to characterize the soil type and subsequently account for soil type ...

Vulnerability and Resilience of Critical Infrastructures due to floods and slides: Case study of Norwegian railway infrastructuresRestricted Access (Master thesis / Masteroppgave, 2014)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Extreme winter events that damage vegetation are considered an important climatic cause of arctic browning—a reversal of the greening trend of the region—and possibly reduce the carbon uptake of northern ecosystems. ...
