Petroleum, coal and research drilling onshore Svalbard: a historical perspective
(Peer reviewed; Journal article, 2019)The beginning of the Norwegian oil industry is often attributed to the first exploration drilling in the North Sea in 1966, the first discovery in 1967 and the discovery of the supergiant Ekofisk field in 1969. However, ... -
Petrology and Provenance of the Upper Cretaceous Strata in Central Utah
(Master thesis, 2015-06-01)The reservoir quality of sandstones is primarily controlled by the primary composition of the rock volume and the effects of later diagenetic processes. Much work has been done to improve the understanding of diagenetic ... -
Petrophysical properties of deformation bands and their influence on fluid flow in carbonate grainstones: insights from the Maghlaq Fault, Malta.
(Master thesis, 2015-06-08)Deformation bands are tabular, sub- centimeter thick zones, which accommodates shear and/or volumetric deformation. Only a few examples of deformation bands have been documented in porous carbonate rocks, and the knowledge ... -
Petrophysical Properties of Deformed Sandstone Reservoir
(Master thesis, 2012-06-21)Small scale deformation structures that mostly occur in highly porous rocks are called deformation bands. Petrophysical characteristics of deformation bands are different from those of host rock and they can act as barriers ... -
Physical and Chemical Processes in the Bjerkreim-Sokndal Magma Chamber

Plaster modelling of fault development and geometry in contractional settings
(Master thesis, 2015-06-01)The aim of this study has been to analyse the development of contractional structures using analogue plaster models. Structures similar to natural fault systems are generated using plaster of Paris as the deforming medium ... -
Plaster modelling of fault development in extensional regimes
(Master thesis, 2015-05-31)The full complexity of deformation in natural extensional regimes is complicated, as direct observation in nature is limited in regards to outcrops and structural evolution over time. The aim of this thesis is to analyse ... -
Pleistocene vertical carbon isotope and carbonate gradients in the South Atlantic sector of the Southern Ocean
(Peer reviewed; Journal article, 2003-01-10)We demonstrate that the carbon isotopic signal of mid-depth waters evolved differently from deep waters in the South Atlantic sector of the Southern Ocean during the Pleistocene. Deep sites (>3700 m) exhibit large ... -
Pliocene sea ice evolution in the Iceland and Labrador Sea – A biomarker approach
(Doctoral thesis, 2017-12-07)Sea ice plays a crucial role in the climate system. Although this is broadly acknowledged, the role of sea ice is not fully understood, especially during warmer periods such as the Pliocene (5.88–2.58 Million years ... -
The PMIP4 contribution to CMIP6 – Part 4: Scientific objectives and experimental design of the PMIP4-CMIP6 Last Glacial Maximum experiments and PMIP4 sensitivity experiments
(Peer reviewed; Journal article, 2017)The Last Glacial Maximum (LGM, 21 000 years ago) is one of the suite of paleoclimate simulations included in the current phase of the Coupled Model Intercomparison Project (CMIP6). It is an interval when insolation was ... -
Pockmarks i indre Aurlandsfjorden: Aktive eller inaktive lekkasjestrukturer Dannelse, alder og biogeokjemiske prosesser
(Master thesis, 2022-03-07)Ved bruk av høyoppløselige batymetris data er det i indre Aurlandsfjorden, Vest-Norge, kartlagt et område på c. 1.2 km2, på vanndyp mellom 40-72 m.u.h. hvor det er identifisert minst 18 pockmark strukturer. De har en ... -
Point-spread function convolution to simulate prestack depth migrated images: A validation study
(Journal article; Peer reviewed, 2021)Seismic migration commonly yields an incomplete reconstruction of the Earth model due to restricted survey aperture, band-limited frequency content and propagation effects. This affects both illumination and resolution of ... -
Polygonalforkastninger - karakteristikk og dannelsesmekanismer. En studie basert på tolking av seismiske data fra Norske-Barentshavsmarginen
(Master thesis, 2014-09-22)Polygonale forkastningssystemer (PFS) er bemerkelsesverdige strukturer som er identifisert i en rekke sedimentære bassenger over hele verden. Polygonalforkastninger er normalforkastninger med små sprang som hovedsakelig ... -
Possible Seismic Effects of Geochemical Processes of Injection of Carbon Dioxide in Carbonate Reservoirs.
(Master thesis, 2017-06-27)The seismic effect of geochemical reactions caused by rock-fluid interactions have been investigated throughout this thesis. Seismic attributes can provide valuable information about rock properties. As a result, rock ... -
The post-Caledonian history of the Røldal Shear Zone (SW Norway): an apatite fission track study
(Master thesis, 2015-04-27)The post-Caledonian tectonic history and landscape evolution of southwestern Norway is not very well understood and therefore the subject of an ongoing debate. The lack of onshore post-Devonian sediments makes the study ... -
Postglacial mass movements and depositional environments in a high-latitude fjord system – Hardangerfjorden, Western Norway
(Peer reviewed; Journal article, 2016-09)High resolution acoustic data and a 15.7 m long sediment core from the Hardangerfjorden system, western Norway, have been analyzed to increase our knowledge on depositional environments, submarine mass movement trigger ... -
Postglasiale sedimentære prosesser og avsetningsmiljø i Skagerrak
(Master thesis, 2015-11-30)Målet med denne studien har vært å kartlegge og studere avsetninger i Skagerrak og sørøstlige deler av Norskerenna for å gi et innblikk i den postglasiale utviklingen mot et moderne sedimentasjonsmønster. I tillegg er ... -
The potential of sedimentary ancient DNA for reconstructingpast sea ice evolution
(Peer reviewed; Journal article, 2019-06-24)Sea ice is a crucial component of the Arctic climate system, yet the tools to document the evolution of sea ice conditions onhistorical and geological time scales are few and have limitations. Such records are essential ... -
Potential secondary events caused by early Holocene paleoearthquakes in Fennoscandia – a climate-related review
(Journal article; Peer reviewed, 2021)During the last deglaciation of Fennoscandia, large earthquakes may have induced secondary effects on the high-latitude coastal regions and continental margins primarily from surface rock avalanches, large and small submarine ... -
Potential Use of Time-Lapse Surface Seismics for Monitoring Thawing of the Terrestrial Arctic
