Progradation rates measured at modern river outlets: A first-order constraint on the pace of deltaic deposition
(Peer reviewed; Journal article, 2019)We present a compilation of modern shoreline progradation rates measured close to river outlets entering deltaic coastlines, and we discuss how these observations relate to the overall evolution of both modern and ancient ... -
Progressive Changes in Magma Transport at the Active Serreta Ridge, Azores
(Journal article; Peer reviewed, 2019)Volcanism in the Eastern Azores Plateau occurs at large central volcanoes and along subaerial and submarine fissure zones, resulting from a mantle melting anomaly combined with transtensional stresses. Volcanic structures ... -
Progressive tilting of salt-bearing continental margins controls thin-skinned deformation
(Peer reviewed; Journal article, 2019)As a primary driving force, margin tilting is crucial for gravity-driven thin-skinned salt tectonics. We investigated how instant versus progressive margin tilting mechanisms influence salt tectonics using an analogue ... -
Prosesser og avsetningsmiljø knyttet til siste deglasiasjon av Norskerenna
(Master thesis, 2014-06-02)Hovedformålet med denne oppgaven har vært å få bedre kunnskap om tilbaketrekningen av Norskerennaisstrømmen gjennom siste deglasiasjonsfase, samt ulike sedimentasjonsmiljø og prosesser knyttet til dette. Studien er basert ... -
Prosessering og tolking av refleksjonsseismiske data frå Isfjorden, Svalbard
(Master thesis, 2015-01-20)I august 2013 vart det samla inn fem 2D multikanals seismiske linjer i Isfjorden på vestkysten av Spitsbergen under SVALEX-kurset. Desse linjene utgjer grunnlaget for denne oppgåva. I den fyrste delen av oppgåva er dei ... -
Prosessering og tolkning av refleksjonsseismiske data fra Isfjorden, Svalbard
(Master thesis, 2015-06-01)Denne oppgaven er basert på syv 2D multikanals seismiske linjer som ble samlet inn ved feltarbeid i Isfjorden i forbindelse med Svalex 2010. Linjene er orientert NNV-SSØ i den østre delen av fjorden. Oppgaven er todelt, ... -
Prosessering og tolkning av refleksjonsseismiske data fra Isfjorden, Svalbard
(Master thesis, 2013-11-17)Fem 2D multikanals seismiske linjer ble samlet inn i Isfjorden under Svalex kursene 2011 og 2012 og danner grunnlaget for denne oppgaven. Linjene har en nordøstlig-sørvestlig retning og de lengste linjene dekker omtrent ... -
Prosessering og tolkning av refleksjonsseismiske data fra Van Mijenfjorden, Svalbard
(Master thesis, 2014-05-31)Grunnlaget for denne oppgaven er elleve multikanals seismiske linjer fra Van Mijenfjorden som ble samlet inn under SVALEX i 2012 og 2013. Oppgaven er todelt og tar først for seg prosesseringsarbeidet av dataene. Her er ... -
Proterozoic Deep Carbon—Characterisation, Origin and the Role of Fluids during High-Grade Metamorphism of Graphite (Lofoten–Vesterålen Complex, Norway)
(Journal article; Peer reviewed, 2023)Graphite formation in the deep crust during granulite facies metamorphism is documented in the Proterozoic gneisses of the Lofoten–Vesterålen Complex, northern Norway. Graphite schist is hosted in banded gneisses dominated ... -
Protracted late Neoproterozic – early Palaeozoic deformation and cooling history of Sør Rondane, East Antarctica, from 40Ar/39Ar and U–Pb geochronology
(Journal article; Peer reviewed, 2020)40Ar/39Ar and U–Pb data from five structural domains constrain the late Neoproterozoic – early Palaeozoic tectonothermal history of the eastern part of the East African–Antarctic Orogen in Sør Rondane. A total of 27 new ... -
Provenance and transport of supraglacial debris revealed by variations in debris geochemistry on Khumbu Glacier, Nepal Himalaya
(Journal article; Peer reviewed, 2023)The origin of supraglacial debris covers is often conceptualised as the formation of a surface lag by melt-out of englacial debris from slow-moving ice, where complexity arises from feedback between debris thickness and ... -
Putative novel hydrogen- and iron-oxidizing sheath-producing Zetaproteobacteria thrive at the Fåvne deep-sea hydrothermal vent field
(Journal article; Peer reviewed, 2023)Iron-oxidizing Zetaproteobacteria are well known to colonize deep-sea hydrothermal vent fields around the world where iron-rich fluids are discharged into oxic seawater. How inter-field and intra-field differences in ... -
Quantifying Dynamical Proxy Potential Through Shared Adjustment Physics in the North Atlantic
(Journal article; Peer reviewed, 2020)Oceanic quantities of interest (QoIs), for example, ocean heat content or transports, are often inaccessible to direct observation, due to the high cost of instrument deployment and logistical challenges. Therefore, ... -
Quantifying structural controls on fluid flow: Insights from carbonate-hosted fault damage zones on the Maltese Islands
(Peer reviewed; Journal article, 2017-08)Structural complexity along faults (e.g., relay zones, fault intersections and jogs) exert strong controls on fluid flow, yet few attempts have been made to quantify and visualise such relationships. This paper does that ... -
Quantitative Comparison of Offshore Sediment Volumes and Onshore Erosion Potential in Norway in the Neogene and Quaternary.
(Master thesis, 2018-06-13)The geodynamic evolution of the Scandinavian topography is the cause of a controversy with several competing hypotheses. Western Scandinavia is characterized by dramatic fjords and high-altitude low-relief surfaces, which ... -
Quantitative interpretation using inverse rock-physics modeling on AVO data
(Peer reviewed; Journal article, 2016-08)Quantitative seismic interpretation has become an important and critical technology for improved hydrocarbon exploration and production. However, this is typically a resource-demanding process that requires information ... -
