Geofaglige vurderinger og kvantifisering av stislitasje i daler rundt Jostedalsbreen og i Jostedalsbreen nasjonalpark, Vestland fylke
(Master thesis, 2024-11-20)Det er forventet at det i fremtiden vil bli økt nedbør og høyere temperaturer, i tillegg til at flere turister vil komme til Vestlandet. En økt ferdsel vil kunne gi utfordringer knyttet til å bevare verneverdiene og ... -
The Thermal Evolution of Western Norway Based on Multi-Sample Models of an Elevation Transect: Implications for the Formation of High-Elevation Low-Relief Surfaces on an Elevated Rifted Continental Margin
(Journal article; Peer reviewed, 2024)The post-Caledonian thermal and geomorphological evolution of onshore Western Norway is poorly understood, including the formation and age of the high-elevation low-relief surfaces seen across the Norwegian landscape. We ... -
Imaging along-strike variability in fault structure; insights from seismic modelling of the Maghlaq Fault, Malta
(Journal article; Peer reviewed, 2024)Seismic modelling studies of outcrop analogues have proven a powerful method to provide a link between geology as observed at outcrop, and the interpretation of subsurface geology from seismic data. Seismic imaging of fault ... -
Lithofacies, petrography, and geochemistry of the Lamphun oceanic plate stratigraphy: As a record of the subduction history of Paleo-Tethys in Chiang Mai-Chiang Rai Suture Zone of Thailand
(Journal article; Peer reviewed, 2024)The Mélange in Lamphun Province, situated in the southern region of the Chiang Mai-Chiang Rai Suture Zone (CMCRSZ), remains inadequately explored. This study employs field investigations and petrographic analysis to delineate ... -
Adverse effects of crushed seafloor massive sulphide deposits on the boreal deep-sea sponge Geodia barretti Bowerbank, 1858 and its associated fauna
(Journal article; Peer reviewed, 2024)Abundant mineral resources in the deep sea are prospected for mining for the global metal market. Seafloor massive sulphide (SMS) deposits along the Mid-Atlantic Ridge are one of the potential sources for these metals. The ... -
Unveiling the inherent physical-chemical dynamics: Direct measurements of hydrothermal fluid flow, heat, and nutrient outflow at the Tagoro submarine volcano (Canary Islands, Spain)
(Journal article; Peer reviewed, 2024)Tagoro is one of the few submarine volcanoes in the world that has been monitored since its early eruptive stage in 2011 to present day. After six multidisciplinary oceanographic cruises conducted between 2014 and 2023 to ... -
Late Glacial-Holocene glacier fluctuations on sub-Antarctic Kerguelen Archipelago (49°S) based on surface exposure dating with in situ cosmogenic nuclides
(Doctoral thesis, 2024-12-17)Vestavindsbeltet på den sørlige halvkule, mellom 40°S og 65°S, the Southern Hemisphere’s westerlies (SHW), hindres i liten grad av landmasser og utgjør derfor et belte av sterke vinder fra vest mot øst. Det har en sterk ... -
Jordskjelvstasjonen i Bergen gjennom 125 år
(Journal article; Peer reviewed, 2024)Seismological studies in Norway initiated in the early 19th century, and since the 1890s, Bergen has been the focal point of Norwegian seismology. Initially, earthquake information was collected through questionnaires and ... -
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 ...
