Multiple late Holocene glacier advances on the sub-Antarctic Kerguelen (49°S) islands: evidence from a 1200 yr sediment core from a glacial threshold basin
(Journal article; Peer reviewed, 2024)Southern Ocean (SO) climate is rapidly changing because of global warming and regional climate feedback loops like shifts of the Southern Hemisphere (SH) westerly winds (SHW) and related Southern Annular Mode (SAM). Over ... -
Palaeogeography and 3D variability of a dynamically uplifted shelf: Observations from seismic stratigraphy of the Palaeocene East Shetland Platform
(Journal article; Peer reviewed, 2024)In the Palaeocene North Sea, pulses in turbidite fan deposition and shelfal progradation have been correlated with episodes of regional uplift caused by a precursor of the Icelandic Plume. In the East Shetland Platform, ... -
Eccentricity pacing and rapid termination of the early Antarctic ice ages
(Journal article; Peer reviewed, 2024)Earth’s obliquity and eccentricity cycles are strongly imprinted on Earth’s climate and widely used to measure geological time. However, the record of these imprints on the oxygen isotope record in deep-sea benthic ... -
High-resolution sediment mass-budget of the Shetland Platform during the Paleocene–Early Eocene; constraints on external forcing by uplift and climate
(Journal article; Peer reviewed, 2025)In the Paleocene–Early Eocene, distinct surface and stratigraphic signals recorded around Shetland have been correlated to hinterland uplift associated with the Icelandic Plume, the effects of the Paleocene–Eocene Thermal ... -
Refining Holocene sea-level variations for the Lofoten and Vesterålen archipelagos, northern Norway: implications for prehistoric human–environment interactions
(Journal article; Peer reviewed, 2024)The Lofoten and Vesterålen archipelagos are located off the outer coast of northern Norway far from the center of the former Fennoscandian Ice Sheet and near the continental shelf edge. Existing relative sea-level (RSL) ... -
Constraints on the Timing and Lower Crustal Accretion at the Schulz Massif, Mohns Ridge, Arctic Mid Ocean Ridges
(Journal article; Peer reviewed, 2024)The ultraslow-spreading Mohns Ridge is a key supersegment of the Arctic Mid-Ocean system, where it represents a boundary between the Jan Mayen hotspot in the south and the highly anomalous Knipovich Ridge to the north. ... -
A position and wave spectra dataset of Marginal Ice Zone dynamics collected around Svalbard in 2022 and 2023
(Journal article; Peer reviewed, 2024)Sea ice is a key element of the global Earth system, with a major impact on global climate and regional weather. Unfortunately, accurate sea ice modeling is challenging due to the diversity and complexity of underlying ... -
Preservation of Hydrothermal Fluid Copper Isotope Signatures in Chalcopyrite-Rich Chimneys: A Case Study From the PACMANUS Vent Field, Manus Basin
(Journal article; Peer reviewed, 2024)Copper isotopes (δ65Cu) in hydrothermal fluids have the potential to provide information on ore-forming processes occurring below the seafloor, but Cu isotope data from high-temperature fluids are scarce. Here, we examine ... -

Hydrochemical study of the desalinisation of quick clays in the Holocene at Tiller-Flotten, Norway
(Master thesis, 2025-01-08)The development of quick clays has been studied for over 50 years in Norway to evaluate and mitigate risk of quick clay landslides. One of the main remaining challenges is qualifying the spatial distribution of quick clays ... -
The collapse of the Caledonian orogen in SW Norway: Insights from quartz textures
(Journal article; Peer reviewed, 2024)Extensional collapse is a common late-to post-collisional feature of orogens. It is particularly prominent in the SW Scandinavian Caledonides, where extensional detachments formed progressively from the initial reactivation ... -
Coastal lake sediments from Arctic Svalbard suggest colder summers are stormier
(Journal article; Peer reviewed, 2024)The Arctic is rapidly losing its sea ice cover while the region warms faster than anywhere else on Earth. As larger areas become ice-free for longer, winds strengthen and interact more with open waters. Ensuing higher waves ... -
The impact of ice-ocean interaction on glacier stability
(Doctoral thesis, 2023-03-31)Havnivåstigning på grunn av dagens klimaoppvarming krever handling fra samfunnet. Hovedusikkerheten i estimatene for havnivåbidraget fra Grønlandsisen grunner i de dy- namiske prosessene som finner sted i grensesnittet ... -
How does a change in climate variability impact the Greenland ice sheet surface mass balance?
(Journal article; Peer reviewed, 2024)Given the long response time of ice sheets, simulations of the Greenland ice sheet typically exceed the availability of input climate data to reliably simulate the fast processes underlying surface mass balance. Strong ... -
Revising chronological uncertainties in marine archives using global anthropogenic signals: a case study on the oceanic 13C Suess effect
(Journal article; Peer reviewed, 2024)Marine sediments are excellent archives for reconstructing past changes in climate and ocean circulation. Overlapping with instrumental records, they hold the potential to elucidate natural variability and contextualize ... -
A solution for constraining past marine Polar Amplification
(Journal article; Peer reviewed, 2024)Most climate proxies of sea surface temperatures suffer from severe limitations when applied to cold temperatures that characterize Arctic environments. These limitations prevent us from constraining uncertainties for some ... -
Fra istidene til storpolitikken-Klima-forskningen ved Institutt for geovitenskap
(Journal article; Peer reviewed, 2024)Palaeoclimate research at The University of Bergen (UiB) has through the last 50 years been developed into a central research environment in Norwegian and international climate research. As a central element of the Bjerknes ... -
Sognefjorden in western Norway – physiography, geomorphology, marine levels and deglaciation history
(Journal article; Peer reviewed, 2024)The landscape formation along Sognefjorden, Norway’s longest and the world’s second longest fjord, involves tectonic activity, glacial erosion during numerous Quaternary ice ages, and mass movements during interglacials ... -
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 ...
