Anoxic Sediments & Ice Coverage: Severe Winter Climate Indicators in the Acrctic from Lake Stuptjørna, Svalbard
(Master thesis, 2024-08-05)The Arctic is experiencing accelerated climate change, which has global significance. Changes in temperature and precipitation in the region affect glacier and ice cap dynamics, sea ice extent, eustatic sea level rise, and ... -
Determining sea-level rise in the Caribbean: A shift from temperature to mass control
(Journal article; Peer reviewed, 2024)Tropical Small Island Developing States (SIDS), such as those in the Caribbean, are among the most vulnerable to the impacts of climate change, most notably sea-level rise. The current sea-level rise in the Caribbean is ... -
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 ... -
The influence of submarine hydrothermal systems on seawater sulfate

Biogeochemical impact of historical submarine mine tailings on benthic ecosystems in the Repparfjord (Northern Norway)
(Journal article; Peer reviewed, 2024)Historical copper mine tailings deposited in the Repparfjord, Northern Norway, provided new insight into the biogeochemical impact of submarine tailings disposals on high-latitude coastal ecosystems. The submarine tailings ... -
Anisotropic Structure of the Core-Mantle Boundary Using Core-Reflected Phases

Rekonstruksjon av Blåskavlen, Aurland, basert på kartlegging og undersøking av innsjøsedimenter
(Master thesis, 2024-06-03)Masterprosjektet sin problemstilling er å rekonstruere Blåskavlen, Aurland, sin variasjon gjennom holocen, basert på studier av innsjøsedimenter og kvartærgeologisk kartlegging. To sedimentkjerner fra Midtre Soleibakkvotni, ... -
Sedimentary processes and sediment properties of glacimarine deposits at Utsira Nord offshore wind site.
(Master thesis, 2024-06-03)Utsira Nord offshore wind farm area, located within the Norwegian Channel, less than 10 km west of Utsira island, is designated to host floating wind turbines for renewable energy production. The Norwegian Channel has been ... -
Simulating future contributions of the Greenland ice sheet to sea-level rise by using a coupled surface mass balance and ice sheet model
(Master thesis, 2024-06-03)The Greenland ice sheet is losing mass at an increasing rate and is expected to be an important contributor to global sea-level rise in the 21st century. Paleoclimatic records suggest that during warmer-than-present ...
