Hydroclimate intensification likely aided glacier survival on Svalbard in the Early Holocene
(Journal article; Peer reviewed, 2025)Accelerated Arctic warming and wetting has global impacts, as the region’s glaciers and ice caps respond to variations in temperature and precipitation, impacting global sea-level change. But as the observations needed to ... -
An Investigation into the Glaciomarine Deposits and Geological Processes in the Western Province of the Sørlige Nordsjø II Offshore Wind Site.
(Master thesis, 2025-02-24)The rising demand for renewable energy has sparked a growing interest in offshore wind power, especially in Norway, which aims to develop 30,000 MW of offshore wind capacity by 2040. To help achieve this goal, the University ... -
Characterization of Geological Evolution and Glaciomarine Sedimentation in the Eastern Part of the Sørlige Nordsjø II Offshore Wind Farm Area.
(Master thesis, 2025-02-24)The Sørlige Nordsjø II (SNII) is located along the southern borders of the Norwegian North Sea. The shallow water depths range from 50 to 70m, suitable for bottom fixed turbines. The Norwegian North Sea has a complex ... -
Sea ice variability from the penultimate glacial to the last interglacial in the Eastern Fram Strait
(Journal article; Peer reviewed, 2025)The ongoing reduction of Arctic sea ice underscores the need to understand the drivers behind sea ice variability and associated ocean-climate impacts. The Last Interglacial, Marine Isotope (sub)Stage (MIS) 5e, and its ... -
On the Billefjorden fault zone in Garmdalen, central Spitsbergen: implications for the mapping of major fault zones during geological fieldwork and for the tectonic history of Svalbard
(Journal article; Peer reviewed, 2024)Background: The present contribution reexamines the geometry of a segment of a presumably long-lived fault in Svalbard, the Balliolbreen Fault segment of the Billefjorden Fault Zone, along which presumably two basement ... -
Bacterial chemolithoautotrophy in ultramafic plumes along the Mid-Atlantic Ridge
(Journal article; Peer reviewed, 2024)Hydrothermal vent systems release reduced chemical compounds that act as an important energy source in the deep sea. Chemolithoautotrophic microbes inhabiting hydrothermal plumes oxidize these compounds, in particular, ... -
Volcanically induced glacier collapses in southern Jan Mayen (Sør-Jan), Norway
(Journal article; Peer reviewed, 2024)Jan Mayen is a small volcanic island situated in the Norwegian–Greenland Sea. The entire island was covered by a contiguous ice cap during the Last Glacial Maximum. The deglaciation of the ice cap was interrupted by a ... -
Bergrunnsgeologi, tektonikk, petrologi, geokjemi og geobiologi ved UiB - fra de høyeste topper til de største havdyp
(Journal article; Peer reviewed, 2024)Dagens geofaglige forskning og utdanning ved Universitetet i Bergen har røtter tilbake til 1880-årene og undersøkelser av geologien på Vestlandet i regi av Bergen Museum. Da Universitetet i Bergen ble opprettet i 1947, ... -
Coordination between deformation, precipitation, and erosion during orogenic growth
(Journal article; Peer reviewed, 2024)Crustal thickening associated with orogenic growth elevates topography, causing orographic enhancement of precipitation, which in turn facilitates local erosion and possibly intensifies localization of deformation. How ... -
Extreme Mantle Heterogeneity Revealed by Geochemical Investigation of In Situ Lavas at the Central Mohns Ridge, Arctic Mid-Ocean Ridges
(Journal article; Peer reviewed, 2024)Mid-ocean ridge basalts reflect the mantle’s composition and reveal processes from melting to eruption. The Mohns and Knipovich Ridges have ultraslow spreading rates, low magma budgets and erupted lavas indicating various ... -
Kvartærgeologi, geomorfologi, maringeologi og paleoklima ved Institutt for geovitenskap, Universitetet i Bergen – fra start til excellence, 1960–1990
(Journal article; Peer reviewed, 2024)The establishment of a full education in Quaternary Geology at the University of Bergen in 1960 led to a strong re-vitalization of Quaternary research in Norway, and to the growth of internationally high-ranked research ... -
50 år med forskning og undervisning i petroleumsgeologi ved UiB
(Journal article; Peer reviewed, 2024)Education of petroleum geologists from University of Bergen from 1972 and onwards coincidences in time with the early development of the Norwegian petroleum industry. The first producing oil field on the Norwegian Shelf, ... -
Assessing the impact of crustal architecture and along-strike rifting propagation on salt deposition and tectonics: Insights from the Moroccan Atlantic margin
(Journal article; Peer reviewed, 2024)The salt-bearing conjugate rifted margins of Morocco and Nova Scotia contain one of the oldest stratigraphic records documenting the opening history of the Central Atlantic Ocean, starting in Late Triassic times. Although ... -
Identifying losers: Automatic identification of growth-stunted salmon in aquaculture using computer vision
(Journal article; Peer reviewed, 2024)During the production of salmonids in aquaculture, it is common to observe growth-stunted individuals. The cause for the so-called “loser fish syndrome” is unclear, which needs further investigation. Here, we present and ... -
Geomagnetisme og Paleomagnetisme ved Universitetet i Bergen
(Journal article; Peer reviewed, 2024)Universitetet i Bergen har spilt ulike roller innen geomagnetisk forskning og observatoriedrift siden 1928, og bygget opp landets første paleomagnetisk laboratorium fra tidlig på 1960-tallet. I denne artikkelen oppsummeres ... -
Seismic probing of buried ancient terrane boundaries - insight into Fennoscandia's Palaeoproterozoic continental formation
(Journal article; Peer reviewed, 2024)Terrane boundaries are usually mapped from structures, lithologies and ages of the bedrock geology. Geophysical studies occasionally used to image terrane boundaries at depth typically yield localised information. In this ... -
Institutt for geovitenskap ved Universitetet i Bergen, 1896–1963
(Journal article; Peer reviewed, 2024)The Department of Earth Science, earlier Department of Geology, was formally established when the University of Bergen was founded in 1946. We therefore celebrated our 75th anniversary in 2021. However, I consider we should ... -
2-D Geodynamic Modeling of the Central South Atlantic Wide Rifted Margins, Implications for Evaporite Deposition
(Journal article; Peer reviewed, 2024)The thick late syn- to early post-rift shallow water evaporites in the most distal part of wide rifted margins is paradoxical with the deep depression at crustal breakup time predicted by isostatically compensated lithospheric ... -
