Development of selective agars for the isolation of Tenacibaculum spp. from ulcerative diseases in aquaculture, with emphasis on Norwegian salmon farming
(Master thesis, 2024-05-27)Ulcerative diseases have become a significant concern in the aquaculture industry on a global scale, including in Norway, where ulcerative diseases have posed increasing challenges for fish welfare, resulting in direct ... -
Proterozoic Deep Carbon—Characterisation, Origin and the Role of Fluids during High-Grade Metamorphism of Graphite (Lofoten–Vesterålen Complex, Norway)
(Journal article; Peer reviewed, 2023)Graphite formation in the deep crust during granulite facies metamorphism is documented in the Proterozoic gneisses of the Lofoten–Vesterålen Complex, northern Norway. Graphite schist is hosted in banded gneisses dominated ... -
Hydrothermal activity fuels microbial sulfate reduction in deep and distal marine settings along the Arctic Mid Ocean Ridges
(Journal article; Peer reviewed, 2023)Microbial sulfate reduction is generally limited in the deep sea compared to shallower marine environments, but cold seeps and hydrothermal systems are considered an exception. Here, we report sulfate reduction rates and ... -
An adaptive solution strategy for Richards' equation
(Journal article; Peer reviewed, 2023)Flow in variably saturated porous media is typically modeled by the Richards equation, a nonlinear elliptic-parabolic equation which is notoriously challenging to solve numerically. In this paper, we propose a robust and ... -
An Assessment of CO2 Uptake in the Arctic Ocean From 1985 to 2018
(Journal article; Peer reviewed, 2023)As a contribution to the Regional Carbon Cycle Assessment and Processes phase 2 (RECCAP2) project, we present synthesized estimates of Arctic Ocean sea-air CO2 fluxes and their uncertainties from surface ocean pCO2-observation ... -
Physical aspects of hydrogen storage in subsurface porous media : Flow mechanisms, hysteresis and storage efficiency
(Doctoral thesis, 2024-06-28)Hydrogen (H2) som energibærer er i dag et prioritert satsningsområde med en rekke prosjekter som lanseres over hele verden. En bred implementering av H2 i sektorer som transport, oppvarming og kraftproduksjon vil kreve ... -
The Ionospheric Current System and its Temporal Evolution during Rapid Solar Wind Dynamic Pressure Increases
(Doctoral thesis, 2024-03-04)Forskning er en jakt på kunnskap om det ukjente. I denne avhandlingen prøver vi å utvide vår kollektive forståelse av de komplekse samspillene innenfor det dynamiske magnetosfære-ionosfæresystemet. Man kunne fristes til å ... -
Reconstructing uplift signals from sediment supply and tectonostratigraphy in a clastic shelf, Early Paleogene Shetland Platform
(Doctoral thesis, 2024-06-25)Sedimentære bassenger er viktige arkiver for planetens geodynamikk og klima. Kompleksiteten til dette registeret innebærer dog at det er en ikke-triviell oppgave å ekstrahere tektoniske og klimatiske svingninger, noe som ... -
Stages in the dynamics of hydrate formation and consequences for design of experiments for hydrate formation in sediments
(Journal article; Peer reviewed, 2019)Natural gas hydrates in sediments can never reach thermodynamic equilibrium. Every section of any hydrate-filled reservoir is unique and resides in a stationary balance that depends on many factors. Fluxes of hydrocarbons ... -
Stratigraphic expression of the Paleocene-Eocene Thermal Maximum climate event during long-lived transient uplift—An example from a shallow to deep-marine clastic system in the Norwegian Sea
(Journal article; Peer reviewed, 2023-02-20)Seismic geomorphology and stratigraphic analysis can reveal how source-to-sink systems dynamically respond to climatic and tectonic forcing. This study uses seismic reflection data from the Norwegian Sea to investigate the ... -
Multi-Scale Analysis of Gas Hydrates Phase Transitions Focusing on Long-Term CO2 Sequestration
(Doctoral thesis, 2024-06-27)Hovedmålet med denne avhandlingen var å utvide vår forståelse av gass hydrat faseoverganger med særlig fokus på langvarig CO2-lagring i sedimenter under havbunnen. Hydrater er krystallinske stoffer som inneholder små ... -
Plant traits and associated data from a warming experiment, a seabird colony, and along elevation in Svalbard
(Journal article; Peer reviewed, 2023)The Arctic is warming at a rate four times the global average, while also being exposed to other global environmental changes, resulting in widespread vegetation and ecosystem change. Integrating functional trait-based ... -
Flower imprints from the history of mires and humans : A palynological study of rich fen development and periods of human land use over the last 8000 years in boreal Norway
(Doctoral thesis, 2024-06-25)Kulturvegetasjon på boreale slåttemyrer har for første gong vorte rekonstruert tilbake til den romerske jernalderen. Slåtten på myrene heldt fram til midten av 1900-talet i norske utmarker, og representerer ein del av den ... -

Exploring Geospace Dynamics Through Ground Magnetic Perturbations during Substorms
(Doctoral thesis, 2024-06-18)Dynamikken på dagsiden av ionosfæren styres hovedsakelig av samspillet mellom det interplanetære magnetfeltet (IMF) og jordens magnetfelt på dagsiden av magnetopausen, mens dynamikken på nattsiden hovedsakelig drives av ... -
The Nature of High-Energy Tail Electron Precipitation
(Doctoral thesis, 2024-06-14)Denne avhandlingen er en del av en større forskningsinnsats ved Universitetet i Bergen som prøver å forstå "Hva er effektene av partikkelnedbør på atmosfæren?". Ett viktig steg mot et svar er å forbedre parametriseringen ... -
Prescribed burning can promote recovery of Atlantic coastal heathlands suffering dieback after extreme drought events
(Journal article; Peer reviewed, 2023)Questions During the winter of 2014, an intense drought combined with sub-zero temperatures resulted in a massive Calluna dieback in Norwegian heathlands. We studied the initial vegetation recovery under two management ... -
