U-Pb zircon provenance of metamorphosed clastic sediments in a developing rift (Dom Feliciano Belt, Uruguay and Kaoko Belt, Namibia)
(Master thesis, 2014-11-17)Geochronological studies of the westernmost part of the Kaoko Belt in Namibia, the Coastal Terrane, revealed zircons with distinct Neoproterozoic ages, that are no known from other parts of this orogen and an exotic origin ... -
UncertainData.jl: a Julia package for working with measurements and datasets with uncertainties
(Journal article; Peer reviewed, 2019-11-01)UncertainData.jl provides an interface to represent data with associated uncertainties for the Julia programming language (Bezanson, Edelman, Karpinski, & Shah, 2017). Unlike Measurements.jl (Giordano, 2016), which deals ... -
Undersøkelser av alder, volum og utbredelse av Gloppedalsura, Bjerkreim og Gjesdal kommuner, i Rogaland
(Master thesis, 2018-06-30)This master thesis examines the age, volume and extent of Gloppedalsura in Bjerkreim and Gjesdal communities in Rogaland county. The Schmidt Hammer is used for estimating age. This method is widely used as a relative dating ... -
Unraveling distinctive sulphide mineralization and hydrothermal alteration on shallow seafloor hydrothermal systems
(Master thesis, 2017-04-22)Since the discovery of seafloor hydrothermal systems in the late 1970´s, they have been found in different types of geological settings. Recent discoveries of active, inactive and inferred vent fields on the Arctic Mid ... -
Urban basin deposit. The pollution history of Lille Lungegårdsvannet, Bergen
(Doctoral thesis, 2014-12-09)The sediments within urban lakes will, if left undisturbed, reflect a part of the history of the city through the record of chemical compounds. The sediment chemistry in Lille Lungegårdsvannet in Bergen city is ... -
Use of inverse rock physics modeling in reservoir characterization
(Master thesis, 2012-05-31)Reservoir characterization based on seismic data demands a robust and reliable method that transforms seismically derived parameters such as elastic moduli, P-velocity, S-velocity or acoustic impedance into parameters ... -
Using climate to relate water-discharge and area in modern and ancient catchments
(Peer reviewed; Journal article, 2018-06)Models relating sediment supply to catchment properties are important in order to use the geological record to deduce landscape evolution and interplay between tectonics and climate. Water-discharge (Qw) is an important ... -
Using grain size analysis to understand transverse versus axial sediment supply to a rift: Example from the Sperchios rift, Greece
(Master thesis, 2016-06-01)In order to better understand the interaction between different controlling variables in fluvial systems in a rift basin, and the differences between transverse and axial drainage in the same setting, I present the results ... -
Using simulations of the last millennium to understand climate variability seen in palaeo-observations: Similar variation of Iceland-Scotland overflow strength and Atlantic Multidecadal Oscillation
(Peer reviewed; Journal article, 2015-02-10)A recent palaeo-reconstruction of the strength of the Iceland–Scotland overflow during the last 600 years suggests that its low-frequency variability exhibits strong similarity with palaeo-reconstructions of the Atlantic ... -
Using stable copper isotopes to trace contamination from two historical mining sites in Norway
(Master thesis, 2020-07-01)During the last few decades, the stable copper isotope system (d65Cu) has gained attention because of its potential as a method to indicate the source of copper in contaminated surface waters. The d65Cu of dissolved copper ... -
Using VSP to improve interpretation of ocean bottom seismic
(Master thesis, 2011-02-21)Operating companies work continuously on increasing their knowledge about the reservoir. In mature areas of the North Sea many wells have been drilled, which can be used to obtain improved images of the subsurface in the ... -
Variability in ISOW vigor over the last 1300 years and its relationship to climate
(Master thesis, 2009-06-02)Resolving the scale and origins of recent low frequency (decadal-centennial) climate variations, such as the AMO, is crucial for predicting how natural variability and anthropogenic forcing will interact to affect future ... -
Variability of precipitation in complex terrain and the investigation of representativeness of a single point measurement for the Matre Hydro System, Western Norway.
(Master thesis, 2009-06-08)Orography is strongly affecting precipitation. Especially over complex terrain, the precipitation fields can show high spatial variability even over very small scales. In cooperation between the power company BKK ... -
Variations in Iceland-Scotland Overflow Water during the penultimate interglacial
(Master thesis, 2018-12)There is a growing body of evidence suggesting that the density and speed of the Nordic Seas overflows experienced significant changes on both centennial and multi-millennial time scales throughout the penultimate interglacial ... -
Variations of the Ice Shelf Water in the southern Weddell Sea, Antarctica
(Master thesis, 2011)Ice Shelf Water (ISW) characteristics are investigated using data from moored instruments in the southern Weddell Sea. Most attention is given to the temperature data, but additional current, salinity and oxygen data are ... -
Vertikal utbredelse av glasialt transportert materiale på Gaustatoppen
(Master thesis, 2015-09-03)Gaustatoppen (1883 m o.h.) er en ikonisk fjelltopp i Sør-Norge, der det tidligere er gjort få kvartærgeologiske undersøkelser. På bakgrunn av blokkhavet som dekker fjellmassivet og toppens høyde i forhold til omkringliggende ... -
Visual Techniques for Geological Fieldwork Using Mobile Devices
(Doctoral thesis, 2017-10-06)Visual techniques in general and 3D visualisation in particular have seen considerable adoption within the last 30 years in the geosciences and geology. Techniques such as volume visualisation, for analysing subsurface ... -
Volcanic rocks at the Møre Marginal High: geochemistry, petrogenesis and emplacement mechanisms
(Master thesis, 2017-06-13)The opening of the Norwegian-Greenland Sea at the Paleocene−Eocene transition was accompanied by extensive magmatic activity, giving rise to the North Atlantic Igneous Province. The magmatic activity is today manifested ... -
Volcaniclastic Dispersal During Submarine Lava Effusion: The 2012 Eruption of Havre Volcano, Kermadec Arc, New Zealand
