Weathering of deep-sea hydrothermal sulfide deposits. Stability of heavy metals and implications for future mining activities
(Master thesis, 2016-12-20)During future mining operations on seafloor massive sulfide deposits, sulfidic material will be reworked and relocated at the seafloor, exposing the material to oxic conditions. In an oxic environment sulfidic material ... -
West Spitsbergen fold and thrust belt: A digital educational data package for teaching structural geology
(Journal article; Peer reviewed, 2023)The discipline of structural geology is taking an advantage of compiling observations from multiple field sites to comprehend the bigger picture and constrain the region's geological evolution. In this study we demonstrate ... -
Wide Versus Narrow Back-Arc Rifting: Control of Subduction Velocity and Convective Back-Arc Thinning
(Journal article; Peer reviewed, 2022)Back-arc basins such as the ones behind the island-arcs of the Western Pacific Ocean or the ones in the Mediterranean Sea are ubiquitous structures of the Earth. They are extensional basins forming in the overriding plate ... -
Widespread glacial erosion on the Scandinavian passive margin
(Journal article; Peer reviewed, 2021)The topography in Scandinavia features enigmatic high-elevation low-relief plateau regions dissected by deep valleys and fjords. These plateau regions have long been interpreted as relict landforms of a preglacial origin, ... -
Winter Arctic Amplification at the synoptic timescale, 1979–2018, its regional variation and response to tropical and extratropical variability
(Journal article; Peer reviewed, 2021)We investigate winter Arctic Amplification (AA) on synoptic timescales and at regional scales using a daily version of the Arctic Amplification Index (AAI) and examine causes on a synoptic scale. The persistence, frequency ... -
Zippered Shear Zone Model for Interacting Shear Zones in the Borborema Province, Brazil, as Constrained by U-Pb Dating
(Peer reviewed; Journal article, 2019)Shear zones typically interact to form connected systems or networks to accommodate crustal deformation, but our knowledge of how this happens is fragmentary. Understanding branching and interacting shear zones requires ... -
Zircon provenance of Devonian deposits in Western Norway
(Master thesis, 2011-06-01)The provenance of the Devonian deposits of western Norway has been studied by detrital zircon geochronology. These deposits are found in the Fensfjorden -, Solund -, Kvamshesten -, Hornelen - and Smøla basin. A total of ... -
Årlig flomvariabilitet i Øyeren de siste 250 år basert på sedimentkjerner
(Master thesis, 2023-06-01)Flomskader er en av de mest kostbare naturfarene i Norge. Å innhente ny kunnskap om hvordan de varierer over lengre tidsintervall kan gi verdifull kunnskap om hva det er som driver variasjonen, og i hvilken grad den er ...
