Rift kinematics preserved in deep-time erosional landscape below the northern North Sea
(Journal article; Peer reviewed, 2022)Our understanding of continental rifting is, in large parts, derived from the stratigraphic record. This record is, however, incomplete as it does not often capture the geomorphic and erosional signal of rifting. New 3D ... -
Robust uncertainty assessment of the spatio-temporal transferability of glacier mass and energy balance models
(Peer reviewed; Journal article, 2019-02-08)Energy and mass-balance modelling of glaciers is a key tool for climate impact studies of future glacier behaviour. By incorporating many of the physical processes responsible for surface accumulation and ablation, they ... -
Rock physics and seismic AVA analysis of gas hydrate-bearing sediments
(Master thesis, 2014-06-02)Large amount of natural gas are present in submarine sediments and permafrost areas in the form of gas hydrates. Gas hydrates are a large potential future energy resource, and may contribute to the methane balance in the ... -
Rock physics interpolation Used for velocity modeling of chalks: Ontong Java plateau example
(Peer reviewed; Journal article, 2010)Chalks are pelagic carbonate sediments that are deposited in deep-water environments. Their elastic behaviour is controlled by a combination of depositional conditions and subsequent diagenesis. In this paper, we incorporate ... -
Rock Physics Templates for 4D Seismic Reservoir Monitoring: A case study from Yttergryta field in the Norwegian Sea
(Master thesis, 2014-06-02)Time-lapse 3D seismic which geoscientists often abbreviate to 4D seismic has the potential to monitor changes especially in pore pressure, hydrocarbon and brine saturation in a reservoir due to production or water/gas ... -
The role of authigenic sulfides in immobilization of potentially toxic metals in the Bagno Bory wetland, southern Poland
(Peer reviewed; Journal article, 2015-10)The supply of Cd, Cu, Fe, Pb, Zn, and Tl into a wetland in the industrial area of Upper Silesia, southern Poland via atmospheric precipitation and dust deposition has been counterbalanced by the biogenic metal sulfide ... -
The role of ocean and atmospheric dynamics in the marine-based collapse of the last Eurasian Ice Sheet
(Journal article; Peer reviewed, 2022)Information from former ice sheets may provide important context for understanding the response of today’s ice sheets to forcing mechanisms. Here we present a reconstruction of the last deglaciation of marine sectors of ... -
The role of ocean circulation and sea ice in abrupt climate change
(Doctoral thesis, 2020-01-17)Abrupt changes in Earth's climate have occurred repeatedly throughout the geological record. Evidence from paleoclimate data has revealed that climate changed most dramatically during the last glacial period, associated ... -
The Role of On- and Off-Axis Faults and Fissures During Eruption Cycles and Crustal Accretion at 9°50′N, East Pacific Rise
(Journal article; Peer reviewed, 2023)Fissures and faults provide insight into how plate separation is accommodated by magmatism and brittle deformation during crustal accretion. Although fissure and fault geometry can be used to quantify the spreading process ... -
The role of structural inheritance in the development of high-displacement crustal faults in the necking domain of rifted margins: The Klakk Fault Complex, Frøya High, offshore mid-Norway
(Journal article; Peer reviewed, 2020-08-20)The role of inherited structures during the development of normal faults in continental rifts and proximal domains of passive margins have been extensively studied. Few studies, however, have a focus on deciphering the ... -
The Role of Subduction Interface and Upper Plate Strength on Back-Arc Extension: Application to Mediterranean Back-Arc Basins
(Journal article; Peer reviewed, 2021)While there has been a lot of work focusing on improving our understanding of divergent and convergent plate boundaries, the intricate nature of back-arc extension, where subduction and large-scale extension occur and ... -
The role of subglacial hydrology in ice streams with elevated geothermal heat flux
(Peer reviewed; Journal article, 2020-02-10)The spatial distribution of geothermal heat flux (GHF) under ice sheets is largely unknown. Nonetheless, it is an important boundary condition in ice-sheet models, and suggested to control part of the complex surface ... -
The role of the northward-directed (sub)surface limb of the Atlantic Meridional Overturning Circulation during the 8.2 ka event
(Peer reviewed; Journal article, 2014-10-24)The so-called "8.2 ka event" is widely regarded as a major Holocene climate perturbation. It is most readily identifiable in the oxygen-isotope records from Greenland ice cores as an approximately 160-year-long cold interval ... -
Rotation, narrowing, and preferential reactivation of brittle structures during oblique rifting
(Journal article; Peer reviewed, 2020)Occurrence of multiple faults populations with contrasting orientations in oblique continental rifts and passive margins has long sparked debate about relative timing of deformation events and tectonic interpretations. ... -
Salt decollement and rift inheritance controls on crustal deformation in orogens
(Journal article; Peer reviewed, 2019-09)We investigate the factors that control the shortening distribution and its evolution through time in orogenic belts using numerical models. We present self‐consistent high‐resolution numerical models that simulate the ... -
Sand textural control on shear-enhanced compaction bands in poorly-lithified sandstone
(Peer reviewed; Journal article, 2014)Sand textural control on SECB (shear-enhanced compaction band) formation is analyzed combining field observations, detailed material characterization and mechanical testing for poorly lithified sandstone units in Provence ... -
Scanarray-a broadband seismological experiment in the baltic shield
(Journal article; Peer reviewed, 2021)The ScanArray international collaborative program acquired broadband seismological data at 192 locations in the Baltic Shield during the period between 2012 and 2017. The main objective of the program is to provide ... -
Scattering approaches to modelling and inversion of acoustic and elastic waveform data
(Doctoral thesis, 2023-11-16)Spredningsmetoden er kraftig for å løse direkte og inverse spredningsproblemer i forskjellige bølgespredningsscenarioer. Full bølgeforminversjon, sett på som et ikke-lineært invers spredningsproblem, fremstår som en sentral ... -
Sea ice thickness from air-coupled flexural waves
(Journal article; Peer reviewed, 2021)Air-coupled flexural waves (ACFWs) appear as wave trains of constant frequency that arrive in advance of the direct air wave from an impulsive source travelling over a floating ice sheet. The frequency of these waves varies ... -
Sea Ice Variability in a Warmer Past: Last Interglacial Paleoceanography of the (Sub)Arctic Oceans
(Doctoral thesis, 2024-05-13)Det omfattende og permanente havisdekket som i dag karakteriserer det Arktiske havet er i rask endring med en havoverflate som uunngåelig er i endring fra hvit til blå. Forståelse for en slik omfattende endring og dets ...
