(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Mixed carbonate-siliciclastic systems are complex, and their development can sometimes be difficult to understand, given the various responses to each sub-environment to specific forcing, such as variation in sediment ...
-
(Master thesis / Masteroppgave, 2005)Hammerfestbassenget ligger i bassengprovinsen sør i det vestlige Barentshavet og er et sammensatt sedimentærbasseng, 70 km bredt og 150 km langt, som utviklet seg fra sen jura til tidlig kritt. Prøvesettet i denne ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The Wilhelmøya Subgroup (Norian–Bathonian) is considered as the prime storage unit for locally produced CO2 in Longyearbyen on the Arctic archipelago of Svalbard. We here present new drillcore and outcrop data and refined ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Absolute reconstructions of large igneous provinces (LIPs) for the past 300 Ma reveal a remarkable spatial pattern suggesting that almost all LIPs have erupted over the margins of the two large‐scale structures in the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The common-reflection-surface (CRS) method offers a stack with higher signal-to-noise ratio at the cost of a time-consuming semblance search to obtain the stacking parameters. We have developed a fast method for extracting ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Eikonal models have been widely used for traveltime computations in the field of seismic imaging, but they are often criticized for having low accuracy and poor resolution of the output image. Including amplitude information ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The ice- and organic-rich permafrost of the northeast Siberian Arctic lowlands (NESAL) has been projected to remain stable beyond 2100, even under pessimistic climate warming scenarios. However, the numerical models used ...
-
(Master thesis / Masteroppgave, 2017)Fastmerker etableres for å oppnå et stabilt punkt med så lav punktdeformasjon som mulig. Så langt det er mulig velges også områder med faste, stabile masser for plassering av fastmerker. Av flere årsaker kan det likevel ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Significant uncertainties occur through varying methodologies when interpreting faults using seismic data. These uncertainties are carried through to the interpretation of how faults may act as baffles or barriers, or ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract Laboratory measurements can determine the potential for geologic materials to generate unstable (seismic) slip, but a direct relation between sliding behavior in the laboratory and physical characteristics ...
-
(Doctoral thesis / Doktoravhandling, 2018)The PhD thesis is a collection of four articles that investigate the controls of syn- and post-kinematic faulting on reservoirs. Case studies from the Barents Shelf are presented (Svalbard and the Hammerfest Basin). Offshore ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The fossil biota of the upper Valanginian–lower Hauterivian sediment hosted vent (SHV) environment of Zengővárkony comprises 39 species, 55 genera and higher taxa representing seven phyla. Thirteen of these taxa are reported ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Vegetation indices are corner stones in vegetation monitoring. However, previous field studies on lichens and NDVI have been based on passive sensors. Active handheld sensors, with their own light sources, enables high- ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)The P-Cable technology is an acquisition principle for high-resolution and ultra-high-resolution 3D seismic data. Many 3D seismic datasets have been acquired over the last decade, but the application in time-lapse studies ...
-
(Master thesis / Masteroppgave, 2022)Flytende sensorplatformer "Driftere" kan brukes til å utføre målinger i de tøffe og utilgjengelige forholdene i smeltevannskanaler på bre. Drifterene kan levere et vell av data smeltevannskanaler, men metoder for å trekke ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Fluid-rock interactions exert key control over rock rheology and strain localization. Redox may significantly affect the reaction pathways and, thereby, the mechanical properties of the rock. This effect may become critical ...
-
(Master thesis / Masteroppgave, 2008)Feltarbeid regnes som en essensiell del av geografiutdanningen. Feltarbeid, førstehåndserfaringer tilegnet i et feltområde, blir beskrevet og diskutert for å gi et innblikk i en av geografiundervisningens viktigste metoder. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2009)The long-term safety of future CO2 storage projects in aquifers will not only rely on a comprehensive geological characterisation of the formation and capillary seal, but also on the ability to effectively monitor the ...
-
(Master thesis / Masteroppgave, 2020)In this thesis the rock glaciers and geomorphology of the three fjord arms of Hopsfjorden called, Ivarsfjorden, Store Skogfjorden and Lille Skogfjorden were surveyed. Hopsfjorden is located in Finnmark at 70.9° N and 28° ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)It is now more than 50 years since Tuzo Wilson published his paper asking ‘Did the Atlantic close and then re-open?’. This led to the ‘Wilson Cycle’ concept in which the repeated opening and closing of ocean basins along ...
