The influence of glacial landscape evolution on Scandinavian ice-sheet dynamics and dimensions
(Journal article; Peer reviewed, 2024)The Scandinavian topography and bathymetry have been shaped by ice through numerous glacial cycles in the Quaternary. In this study, we investigate how the changing morphology has influenced the Scandinavian ice sheet (SIS) ... -
Sub-regional variability in the influence of ice-contact lakes on himalayan glaciers
(Journal article; Peer reviewed, 2024)Ice-contact lakes modify glacier geometry and dynamics by shifting the majority of mass loss from the ice surface to the terminus. Lake-terminating glaciers are known to experience greater thinning rates and higher velocities ... -
A 7000-year record of extreme flood events reconstructed from a threshold lake in southern Norway
(Journal article; Peer reviewed, 2024)Recent decades have witnessed a shift in the seasonality and frequency of river floods in Norway, primarily attributed to contemporary global warming. Such changes necessitate a more comprehensive understanding of climate-flood ... -
Fluid Inclusion Study of Antarctic Blue Ice Gypsum
(Master thesis, 2024-09-16)Gypsum, the most common sulfate mineral, has a hardness of 2 on the Mohs scale and is typically formed through seawater evaporation. However, a large aggregate of gypsum was discovered within blue ice moraines on the ... -
Stratigraphic and paleoceanographic alternations within a Mediterranean semi-enclosed, syn-rift basin during Marine Isotope Stage 5: The Gulf of Corinth, Greece
(Journal article; Peer reviewed, 2024)The Gulf of Corinth represents an ideal setting for studying the impact of sea level changes and regional climate on a semi-enclosed, syn-rift basin. Here we investigate the stratigraphic and paleoceanographic variability ... -
Metallogenic model of the Lykling ophiolite-hosted lode Au deposit, Scandinavian Caledonides: Insight from fluid inclusions, mineral chemistry and stable isotope geochemistry
(Journal article; Peer reviewed, 2024)The Lykling lode Au deposit represents a unique example of gold mineralization in the Upper Allochthone of the Scandinavian Caledonides. The mineralization is hosted by the Early Ordovician Lykling Ophiolite Complex and ... -
Soundscape characteristics of RAS tanks holding Atlantic salmon (Salmo salar) during feeding and feed withdrawal
(Journal article; Peer reviewed, 2024)Behavioural monitoring can provide crucial information on welfare and feeding in aquaculture. Passive acoustic monitoring of behaviour can be particularly useful in recirculating aquaculture systems (RAS), as they often ... -
Sea ice in the Nordic Seas: Greenland stadial to interstadial changes
(Journal article; Peer reviewed, 2024)Sea ice conditions in the eastern Fram Strait between 40 and 36.5 ka b2k (thousand years before the year 2000) are reconstructed in detail, based on biomarker analyses. Following extensive sea ice conditions around the ... -
Sediment flux variation as a record of climate change in the Late Quaternary deep-water active Corinth Rift, Greece
(Journal article; Peer reviewed, 2024)The value of deep-water sedimentary successions as reliable records of environmental change has been questioned due to their long response times and sediment pathways leading to complex responses to climatic change and ... -
Sedimentary ancient DNA sequences reveal marine ecosystem shifts and indicator taxa for glacial-interglacial sea ice conditions
(Journal article; Peer reviewed, 2024)Sedimentary ancient DNA (sedaDNA) analysis is a promising new approach for reconstructing the impact of past climate and environmental changes on marine paleobiodiversity. By recovering, amplifying, and sequencing taxonomically ... -
On the role of precession in Quaternary glacial cycles
(Journal article, 2023)An outstanding question of the Quaternary glacial cycles is the gradual emergence of a precession signal. Its absence in the Early Pleistocene may be explained by Northern Hemisphere ice sheets varying out-of-phase with a ... -
Tectono-sedimentary evolution of high-displacement crustal-scale normal faults and basement highs on rifted margins: Klakk Fault Complex and Frøya High, Mid-Norwegian Margin
(Journal article; Peer reviewed, 2024)Crustal-scale high-displacement (>10 km) normal faults are not captured in existing tectono-sedimentary models of rift basins. We used 2D and 3D seismic reflection and well data to perform a structural and source-to-sink ... -
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
