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, ... -

(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, ... -
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 ... -
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 ... -
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 ... -
Multidisciplinary characterisation of the biodiversity, geomorphology, oceanography and glacial history of Bowditch Seamount in the Sargasso Sea
(Journal article; Peer reviewed, 2024)The first multidisciplinary characterisation of Bowditch Seamount in the Sargasso Sea was conducted to provide new baseline knowledge of the biodiversity, geomorphology, oceanography and glacial history of this seamount. ... -
Deformation Mechanisms During the Syn-Orogenic Extrusion of the High-Pressure Phyllites-Quartzites Unit in the Central and Northern Peloponnese, Greece
(Journal article; Peer reviewed, 2024)The High-Pressure Phyllites-Quartzites (PQ) unit of the External Hellenides is exposed in tectonic windows in the central and northern Peloponnese (Greece). Understanding the deformation history of this unit is essential ... -
Hydrothermal carbon reduction in the absence of minerals
(Journal article; Peer reviewed, 2024)Abiotic synthesis of CH4 in seafloor hydrothermal fluids is generally assumed to occur via heterogeneous reactions on mineral surfaces. Stepwise homogeneous reduction of CO2 has, however, been suggested as an alternative ... -
Late Glacial-Holocene cirque glacier chronology on sub-Antarctic Kerguelen Archipelago (49°S) based on cosmogenic 36Cl exposure dating
(Journal article; Peer reviewed, 2024)Sub-Antarctic glacier chronologies can provide valuable information about the past variability of climate dynamics in the Southern Ocean region. The Kerguelen Archipelago (49°S) is advantageously located under the influence ... -
Seismikk ved UiB - kartlegging av kontinentalsokkelen, geologisk prosessforståelse og innovasjon
(Journal article; Peer reviewed, 2024)This contribution primarily presents the development of Solid Earth land and marine geophysics at the University of Bergen from 1960 until the present. A large number of projects employing controlled seismic sources have ... -
50 år med utvikling av metoder for seismisk prosessering, modellering og inversjon
(Journal article; Peer reviewed, 2024)This article gives a brief overview of research and teaching related to the development of mathematically oriented seismic methods for imaging of geological structures and dynamic processes. This includes the development ... -
Institutt for geovitenskap, Universitetet i Bergen: Fra mineralsamling til breddeinstitutt
(Journal article; Peer reviewed, 2024)Department of Earth Science – and the units that have eventually been consolidated into today’s department – have a 125-year history of development from a few staff members at the Bergens Museum during the first half of ... -
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 ... -
