Geochemistry of hydrothermal fluids from the E2-segment of the East Scotia Ridge: Magmatic input, reaction zone processes, fluid mixing regimes and bioenergetic landscapes
(Journal article; Peer reviewed, 2022)The compositions of hydrothermal fluids in back-arc basins (BABs) can be affected by the influx of magmatic fluids into systems that are dominated by reactions between basement rocks and seawater-derived fluids. The East ... -
Late Quaternary mud-dominated, basin-floor sedimentation of the Gulf of Corinth, Greece: Implications for deep-water depositional processes and controls on syn-rift sedimentation
(Journal article; Peer reviewed, 2022)Syn-rift deep-water muds and mudstones preserve a relatively complete stratigraphic record of tectonic and climatic events. This paper investigates mud-dominated deposits and stratigraphy using core from International Ocean ... -
A conceptual geological model for offshore wind sites in former ice stream settings: The Utsira Nord site, North Sea
(Journal article; Peer reviewed, 2022)Conceptual geological models of the shallow subsurface that integrate geological and geotechnical information are important for more strategic data acquisition and engineering at offshore wind sites. Utsira Nord is an ... -
Climate transition at the Eocene-Oligocene influenced by bathymetric changes to the Atlantic-Arctic oceanic gateways
(Journal article; Peer reviewed, 2022)The Eocene–Oligocene Transition (∼33.9 Ma) marks the largest step transformation within the Cenozoic cooling trend and is characterized by a sudden growth of the Antarctic ice sheets, cooling of the interior ocean, and the ... -
Revised ΔR values for the Barents Sea and its archipelagos as a pre-requisite for accurate and robust marine-based 14C chronologies
(Journal article; Peer reviewed, 2022)The calibration of marine 14C dates requires the incorporation of regionally specific marine reservoir offsets known as ΔR, essential for accurate and meaningful inter-archive comparisons. Revised, regional ΔR (‘ΔRR’) ... -
Comparison between Air Temperature and Land Surface Temperature for the City of São Paulo, Brazil
(Journal article; Peer reviewed, 2022)This study aims to identify the relationship between changes in temperature regarding urbanization processes and seasonality in the city of São Paulo, located in the Tropic of Capricorn. The land surface temperature (LST) ... -
Geofaglig vurdering av konsekvenser ved klimaframskrivinger for verdensarvområdet Vestnorsk fjordlandskap, delområde Geirangerfjorden
(Master thesis, 2022-06-01)I Møre og Romsdal er det forventet en økning i temperatur og nedbør frem mot perioden 2071-2100. Dette inkluderer en økning i årlig middeltemperatur på ca. 3,5-4,0 ºC og en økning i årsnedbør på 15%. Økningen vil føre til ... -
Vurdering og tentativ kvantifisering av stislitasje i Geirangerfjorden verdsarvområde
(Master thesis, 2022-06-01)Ferdsel i stiar fører til auka erosjon i lausmassane og slitasje på forvitringshuda til dei harde overflatene i stiane. Problemstillinga i denne oppgåva omhandlar tentativ kvantifisering av stislitasje i lausmassar og på ... -
Processing and interpretation of reflection seismic data from Isfjorden, Svalbard
(Master thesis, 2022-06-01)The geology of the present-day Svalbard is complex and has formed through several million years of repeated episodes of orogeneses, uplift, deformation and erosion. This has resulted in complex deformation structures and ... -
Crystallographic orientation mapping of lizardite serpentinite by Raman spectroscopy
(Journal article; Peer reviewed, 2022)The serpentine mineral lizardite displays strong Raman anisotropy in the OH-stretching region, resulting in significant wavenumber shifts (up to ca. 14.5 cm−1) that depend on the orientation of the impinging excitation ... -
Sen-holocene maringeologiske avsetningsprosesser i Førdefjorden
(Master thesis, 2022-06-01)Fjordlandskapet langs den vestnorske kysten er viktige maringeologiske arkiv grunnet deres semi-isolerte morfologi. Fjordbassengenes sedimentære avsetninger består hovedsakelig av sediment knyttet til proksimale- og distale ... -
Interpretation of alluvial deposits in deep directional resistivity data: the Triassic Skagerrak Formation, Ivar Aasen, Utsira High
(Master thesis, 2022-06-01)A significant amount of hydrocarbons are contained within fluvial deposits, which constitute potential CO2 storage sites. The Skagerrak 2 reservoir zone of the Triassic Skagerrak Formation in the Ivar Aasen field (North ... -
Holocene skredhendingar i Sulafjorden og på Hareidlandet, Sunnmøre
(Master thesis, 2022-06-01)Masteroppgåva har som formål å undersøkje om det er ein potensiell samanheng mellom observerte holocene skredhendingar og jordskjelv eller om det er tsunami, i Sulafjorden og i innsjøsedimenter på Hareidlandet. Problemstillinga ... -
Evolution of ore-forming fluids in a post-collisional porphyry Cu-Au system: A case study from the Bučim deposit, Republic of North Macedonia
(Journal article; Peer reviewed, 2022)The Bučim porphyry Cu-Au deposit is situated in the westernmost part of the Serbo-Macedonian Massif, Republic of North Macedonia. The deposit is hosted by Precambrian gneisses with tectonically imbedded rare lenses of ... -
Elastic Imaging and Full Waveform Inversion for Carbon Sequestration
(Master thesis, 2022-06-01)Geological sequestration of carbon dioxide (CO2) is essential to reduce the effects of global warming. However, this requires careful monitoring. Reflection seismics collects data from a large area and is therefore the ... -
Impact of runoff temporal distribution on ice dynamics
(Journal article; Peer reviewed, 2022)Record highs of meltwater production at the surface of the Greenland ice sheet have been recorded with a high recurrence over the last decades. Those melt seasons with longer durations, larger intensities, or with both ... -
Skredkartlegging og 10Be-eksponeringsdatering av fjellskred i Bondhusdalen, Kvinnherad kommune
(Master thesis, 2022-06-01)I Norge er skred den naturfaren som tar flest menneskeliv. Skred er en landskapsendrende prosess, med hurtige massebevegelser av bergartsfragmenter, løsmasser, vann og snø. Ulike skredprosesser avsetter landformer og ... -
Last interglacial sea-level proxies in the glaciated Northern Hemisphere
(Journal article; Peer reviewed, 2022)Because global sea level during the last interglacial (LIG; 130–115 ka) was higher than today, the LIG is a useful approximate analogue for improving predictions of future sea-level rise. Here, we synthesize sea-level ...
