Assessing rock glaciers for their hydrological significance in the Semi-arid Andes, Chile
(Master thesis, 2024-08-05)Rock glacier plays an important hydrological role in the semi-arid Chilean Andes, acting as buffers against water scarcity in a warming climate. This role will become more significant in the future since the glaciers in ... -
Increasing fault slip rates within the Corinth Rift, Greece: A rapidly localising active rift fault network
(Journal article; Peer reviewed, 2024)As a young (<5 Myr old) active rift with high resolution spatial and temporal constraints, the Corinth Rift is a natural laboratory for testing models of rift and fault network development in the early stages of continental ... -
Transition from Late-Miocene syn-orogenic extension to Plio-Pleistocene Corinth Rifting in the Southern Hellenides, Northern Peloponnese, Greece
(Journal article; Peer reviewed, 2024)This study investigates the Late Miocene to Pliocene transition from contractional to extensional tectonics in the upper plate of the Western Aegean retreating subduction system focusing on the Northern Peloponnese area, ... -
Trace Element and Sulfur Isotope Signatures of Volcanogenic Massive Sulfide (VMS) Mineralization: A Case Study from the Sunnhordland Area in SW Norway
(Journal article; Peer reviewed, 2024-04-07)The Sunnhordland area in SW Norway hosts more than 100 known mineral occurrences, mostly of volcanogenic massive sulfide (VMS) and orogeny Au types. The VMS mineralization is hosted by plutonic, volcanic and sedimentary ... -
A Three-Field Formulation for Two-Phase Flow in Geodynamic Modeling: Toward the Zero-Porosity Limit
(Journal article; Peer reviewed, 2024)Two-phase flow, a system where Stokes flow and Darcy flow are coupled, is of great importance in the Earth's interior, such as in subduction zones, mid-ocean ridges, and hotspots. However, it remains challenging to solve ... -
Volcanic activity and temporal evolution of ultraslow-spreading ridges
(Doctoral thesis, 2024-09-05)Det overordnede målet med denne studien har vært å øke vår forståelse av vulkansk aktivitet langs jordens ultrasakte sprederygger. Avhandlingen består av tre deler som sikter mot å: (I) Forstå den romlige og tidsmessige ... -
The High Arctic Large Igneous Province: first seismic-stratigraphic evidence for multiple Mesozoic volcanic pulses on the Lomonosov Ridge, central Arctic Ocean
(Journal article; Peer reviewed, 2023)We use seismic reflection data acquired by an over-winter expedition on drifting sea ice in the central Arctic Ocean to explore a possible spatial and temporal magmatic relation between the sub-bottom geology of part of ... -

Geochemistry and geochronology of hydrothermally enriched sediments associated with three vent fields along the Mohns Ridge
(Master thesis, 2024-06-03)Hydrothermally enriched sediments are linked to hydrothermal systems on the seafloor, and thus, studies utilizing sediment cores represent a narrative method to investigate hydrothermal activity. Plume particles from active ... -
3D seismic investigation of tunnel valleys in the Sørlige Nordsjø II offshore wind site: morphology, cross-cutting relationships, and glacial history
(Master thesis, 2024-06-03)Sørlige Nordsjø II (SNII) is an offshore wind site situated in the Southern Norwegian North Sea and is part of the larger goal to decarbonise the energy industry. The shallow geology of the North Sea is highly heterogeneous, ... -
An investigation on the development of liquid water content in different snow types during slushflow-inducing weather conditions
(Master thesis, 2024-06-03)Slushflows, defined as rapid mass-movements of water-saturated snow, occur when high liquid water content (LWC) causes bonds to melt and the snowpack to lose cohesion, triggering flow. Characterized by their shallow release ... -
Flomavsetninger i Øyeren og identifisering av ulike sedimentkilder
(Master thesis, 2024-06-03)I denne oppgaven er geokjemiske og magnetiske egenskaper analysert i jordartsprøver fra nedbørsfeltene til Øyeren i Glommavassdraget. Prøvene er sammenlignet med sedimenter fra innsjøens dypbasseng, og analysert gjennom ... -
