A method for generating volumetric fault zone grids for pillar gridded reservoir models
(Peer reviewed; Journal article, 2015-08)The internal structure and petrophysical property distribution of fault zones are commonly exceedingly complex compared to the surrounding host rock from which they are derived. This in turn produces highly complex fluid ... -

Metodar for demping av fleksurbølgjer i havis
(Master thesis, 2015-03-23)Seismiske innsamlingar på flytande havis gir under visse forhold opphav til kjeldeinduserte fleksurbølgjer (Sunwall et al., 2012). Desse oppstår kor seismisk energi blir fanga mellom grenseflatene is/luft og is/vatn. ... -
Microbial community structure in Arctic lake sediments reflect variations in Holocene climate conditions
(Journal article; Peer reviewed, 2020)The reconstruction of past climate variability using physical and geochemical parameters from lake sedimentary records is a well-established and widely used approach. These geological records are also known to contain large ... -
Microseismic wavefield modelling in anisotropic elastic media using integral equation method
(Journal article; Peer reviewed, 2023)In this paper, we present a frequency-domain volume integral method to model the microseismic wavefield in heterogeneous anisotropic-elastic media. The elastic wave equation is written as an integral equation of the ... -
Microseismic Waveform Modeling and Inversion using Finite-Difference and Global Optimization
(Master thesis, 2023-06-01)Estimating microseismic source parameters is an essential part of a microseismic monitoring project. Typically the microseismic source position and origin time are estimated utilizing kinematic methods, while the moment ... -
Microstructure and fluid flow in the vicinity of basin bounding faults in rifts – The Dombjerg Fault, NE Greenland rift system
(Journal article; Peer reviewed, 2021)Faults commonly form loci for high fluid flux in sedimentary basins, where fluids, rocks and deformation processes frequently interact. Here, we elucidate the interaction of fluid flow, diagenesis and deformation near ... -
Mid-Pliocene Atlantic Meridional Overturning Circulation simulated in PlioMIP2
(Journal article; Peer reviewed, 2021)In the Pliocene Model Intercomparison Project Phase 2 (PlioMIP2), coupled climate models have been used to simulate an interglacial climate during the mid-Piacenzian warm period (mPWP; 3.264 to 3.025 Ma). Here, we compare ... -
Mid-Pliocene West African Monsoon rainfall as simulated in the PlioMIP2 ensemble
(Journal article; Peer reviewed, 2021)The mid-Pliocene warm period (mPWP; ∼3.2 million years ago) is seen as the most recent time period characterized by a warm climate state, with similar to modern geography and ∼400 ppmv atmospheric CO2 concentration, and ... -
Middle to Late Triassic (Ladinian to Carnian) palynology of shallow stratigraphic cores 7831/2-U-2 and 7831/2-U-1, offshore Kong Karls Land, Norwegian Arctic
(Master thesis, 2015-11-20)During the Triassic, the Barents Shelf was situated on the northwestern corner of the Pangaea supercontinent as a large epicontinental seaway. Into early Late Triassic (Carnian), a major delta, prograding from the southeast ... -
Middle to Late Triassic (late Ladinian - late Carnian) palynology of the shallow stratigraphic core 7534/4-U-1, Sentralbanken High, Northern Barents Sea
(Master thesis, 2015-09-11)In the Triassic period, a large seaway developed on the northern coast of Pangea, in the area which is the present-day Barents Sea. Deposition of sediment sourced from the Uralian Mountains in-filled this sea during the ... -
Miljøkonsekvenser av tidligere gruvedrift på Litlabø, Stord
(Master thesis, 2023-06-01)Gruvedrift medfører miljøutfordringer, der håndteringen av sulfidholdige overskuddsmasser er spesielt utfordrende siden oksidering og forvitring av disse massene ofte medfører sur avrenning og utlekking av miljøskadelige ... -
Mineraldannende prosesser, biosignaturer og finkornede sedimenter i karstgrotter ved Reingardslivatnet, Mo i Rana
(Master thesis, 2018-09-11)Reingardslisystemet er et grottesystem utviklet i en marmorsone som strekker seg 2,5 km i øst-vestlig retning i Reingardslia (Mo i Rana). Systemet regnes i dag som et av de lengste grottesystemene i Norge med en total ... -
Mineralogical controls on the weathering characteristics of arid continental deposits of the Colorado Plateau
(Master thesis, 2015-06-01)The Permian to Jurassic stratigraphy of the Colorado Plateau includes a number of units that were deposited under arid depositional conditions. These units each show distinctive weathering characteristics which cannot ... -
Mineralogical distribution and genetic aspects of cobalt at the active Fåvne and Loki’s Castle seafloor massive sulfide deposits, Arctic Mid-Ocean Ridges
(Journal article; Peer reviewed, 2023)The demand for responsibly sourced cobalt has increased dramatically as a result of the global transition to ‘fossil-free’ electromobility. However, the distribution, mineralogical expressions and mechanisms of concentration ... -
Minibasin depocentre migration during diachronous salt welding, offshore Angola
(Peer reviewed; Journal article, 2019)Salt tectonics is an important part of the geological evolution of many continental margins, yet the four‐dimensional evolution of the minibasins, the fundamental building block of these and many other salt basins, remains ... -
Minimum 1D velocity model and local magnitude scale for Myanmar
