Deglasiasjon og holocene havnivåendringer i Lofthus, Ullensvang kommune, basert på kvartærgeologisk kartlegging og eksponeringsdatering
(Master thesis, 2018-10-24)Observations from Quaternary geological mapping, LIDAR-data, aerial photo analysis and results from surface exposure dating via in situ ^10Be are used to reconstruct Holocene sea-level changes and the course of deglaciation ... -
Deglasiasjon og strandforskyvning på Bokn, Sørvest-Norge.
(Master thesis, 2017-06-29)In this master thesis the late glacial shoreline displacement on Bokn is presented. The data is based on identification of the isolation and ingression contacts in sediment cores from the two isolation basins Gunnarstavatnet ... -

Deglasiasjonsforløpet og sedimentære prosesser i Bjørnafjordsystemet
(Master thesis, 2018-06-22)Hovedformålet med denne studien har vært å rekonstruere deglasiasjonsforløpet av Bjørnafjordsystemet i Vest-Norge, på bakgrunn av sedimentære prosesser og avsetningsmiljø. Datagrunnlaget baseres på høyoppløselige topas ... -

Delimiting morphological and volumetric elements of cave surveys as analogues for paleokarst reservoir modelling – A case study from the Maaras cave system, northern Greece
(Journal article; Peer reviewed, 2021)Active karst systems can offer good analogues for paleokarst reservoir modelling as they can provide links between present karst system geometries and the final reservoir architecture. Although clastic sediments are a ... -
Deltaic clinothems − Digital data capture, geometries, and reservoir implications
(Doctoral thesis, 2008-12-15)Subsurface reservoir models are typically limited by a lack of spatially accurate geometric data on bedform architecture and geometry, which are key controls on fluid flow. Outcrop analogues have long been utilized as a ... -
Depositional and structural relationships along the basement-Cambrian contact in the Hardangervidda area
(Master thesis, 2016-06-01)The Scandinavian sub-Cambrian peneplain is an important reference surface used in reconstructing the geological evolution from the Neoproterozoic to the present. A detailed study of the geomorphological and structural ... -
Depth‐dependent permeability and heat output at basalt‐hosted hydrothermal systems across mid‐ocean ridge spreading rates
(Journal article; Peer reviewed, 2018)The permeability of the oceanic crust exerts a primary influence on the vigor of hydrothermal circulation at mid‐ocean ridges, but it is a difficult to measure parameter that varies with time, space, and geological setting. ... -
Design of the subsurface observatory at Surtsey volcano, Iceland
(Peer reviewed; Journal article, 2019-06-12)Surtsey, the youngest of the islands of Vestmannaeyjar, is an oceanic volcano created by explosive basaltic eruptions during 1963–1967 off the southern coast of Iceland. The subsurface deposits of the volcano were first ... -
Detailed lithospheric structure of an arc-continent collision beneathTaiwan revealed by joint inversion of seismological and gravity data
(Peer reviewed; Journal article, 2019)The largest compilation of seismological and gravimetry data are combined in a sequential inversion to shed light on unresolved crustal structures in Northern Taiwan and Southernmost Ryukyu area. Our density and seismic ... -
Detaljkartlegging av skredfare i Mobergslia, Os kommune, Hordaland
(Master thesis, 2011)Detaljert kartlegging av lausmassane, med hovudfokus på skredavsetjingar og kartlegging av skredfare er utført i området rundt Mobergslia, sør for Liafjellet i Os kommune, Hordaland. Det er laga eit lausmassekart og eit ... -
Detecting anaerobic methane oxidation coupled to sulfate reduction in hydrothermal sediments
(Master thesis, 2022-03-07)The barite field is a low-temperature vent field, characterized by microbial activity and high fluid values of $NH_4$, $SO_4^{2-}$, and $CH_4$. Geochemical analysis indicates a hydrothermal system with a sedimentary input ... -
Detecting multiscale karst features including hidden caves using microgravimetry in a Caledonian nappe setting: Mefjell massif, Norway.
(Peer reviewed; Journal article, 2018-11-20)Cave passages and karst features form negative density contrasts expressed in gravity field anomalies. We present an interpretation approach for microgravimetry, applicable for challenging geological settings with heterogeneous ... -
Detrital zircon provenance of the Bremnes Migmatite Complex on Bømlo, SW Norway
(Master thesis, 2021-09-29)Detrital zircon provenance, geochemistry, and field descriptions from the Bremnes Migmatite Complex provide new insights in the origin and evolution of the Early Ordovician ophiolitic terrane of SW Norway. The Bremnes ... -
Development of extensional growth basins: A field based study, Svalbard, Norway
(Doctoral thesis, 2020-02-27)The growth style and evolution of syn-sedimentary faults influence the architecture of the basin and thus control both the geometries and distribution of sedimentary facies belts. The architecture of sedimentary basin fill ... -
Development of Gilbert-type deltas: sedimentological case studies from the Plio-Pleistocene of Corinth Rift, Greece
(Doctoral thesis, 2014-05-28)Gilbert-type deltas form where a river system debouches into a relatively deep marine or lacustrine basin, whereby the subaqueous delta slope is steep and fully dominated by sediment gravity-transport processes. These ... -
