An experimental study of foams stabilized by anionic and non-ionic surfactants for geological carbon storage in saline aquifers.
(Master thesis, 2024-06-17)CCS (Carbon Capture and Storage) is regarded as an important contributor in mitigating CO2 emissions and combating climate change. With increased focus on CCS as an option to reduce CO2 emissions, new CCS projects include ... -
Investigating voltage ripple effects in PEM electrolysis: test protocol development and experimental characterisation
(Master thesis, 2024-08-01)PEM water electrolysis is a key technology for producing high-purity hydrogen with a compact design. However, the widespread adoption of PEM electrolysers faces challenges such as the high cost associated with the power ... -
Diversity, habitat endemicity and trophic ecology of the fauna of Loki’s Castle vent field on the Arctic Mid-Ocean Ridge
(Journal article; Peer reviewed, 2024)Loki’s Castle Vent Field (LCVF, 2300 m) was discovered in 2008 and represents the first black-smoker vent field discovered on the Arctic Mid-Ocean Ridge (AMOR). However, a comprehensive faunal inventory of the LCVF has not ... -
More Frequent Abrupt Marine Environmental Changes Expected
(Journal article; Peer reviewed, 2024)We quantify an elevated occurrence of abrupt changes in ocean environmental conditions under human-induced climate forcing using Earth system model output through a novel analysis method that compares the temporal evolution ... -
A Pore-Level Study of Dense-Phase CO2 Foam Stability in the Presence of Oil
(Journal article; Peer reviewed, 2024)The ability of foam to reduce CO2 mobility in CO2 sequestration and CO2 enhanced oil recovery processes relies on maintaining foam stability in the reservoir. Foams can destabilize in the presence of oil due to mechanisms ... -
Trace Element and Sulfur Isotope Signatures of Volcanogenic Massive Sulfide (VMS) Mineralization: A Case Study from the Sunnhordland Area in SW Norway
(Journal article; Peer reviewed, 2024-04-07)The Sunnhordland area in SW Norway hosts more than 100 known mineral occurrences, mostly of volcanogenic massive sulfide (VMS) and orogeny Au types. The VMS mineralization is hosted by plutonic, volcanic and sedimentary ... -
Interannual differences in sea ice regime in the north-western Barents Sea cause major changes in summer pelagic production and export mechanisms
(Journal article; Peer reviewed, 2024)The Barents Sea is a highly dynamic and productive marine ecosystem and a hotspot of global warming. Variability in sea ice extent is a common feature in the Barents Sea with substantial movements of the sea ice edge on ... -
Geodiversity and Biodiversity
(Journal article; Peer reviewed, 2023)Non-living and living nature are inherently connected. Geodiversity, which consists of the variation in geology, soils, topography, geomorphology and hydrology, is seen as the foundation and stage for biodiversity. Underlying ... -
Pore-level Dense Phase CO2 Foam Dynamics during CO2 EOR and CO2 Storage
(Doctoral thesis, 2024-09-26)Rask befolkningsvekst, økende velstand og økonomisk ekspansjon bidro til at behovet for energi økte med 1.3% i 2022. Det økende energibehovet kan sees på som en trussel ettersom energiproduksjon representerer tre fjerdedeler ... -
On the strength of E and F region irregularities for GNSS scintillation in the dayside polar ionosphere
(Journal article; Peer reviewed, 2024)We present results of the study conducted to quantify the relative contribution of different ionospheric regions to phase scintillation in Global Navigation Satellite Systems (GNSS) at the dayside high latitude ionosphere. ... -
Blue mussel (Mytilus edulis) silage, a possible low trophic marine protein source for Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2024)Blue mussel (Mytilus edulis) could be a promising marine protein source in fish feeds and is of great interest since it can be cultivated along the Norwegian coastline. However, the use of blue mussels in feeds is dependent ... -
A Three-Field Formulation for Two-Phase Flow in Geodynamic Modeling: Toward the Zero-Porosity Limit
(Journal article; Peer reviewed, 2024)Two-phase flow, a system where Stokes flow and Darcy flow are coupled, is of great importance in the Earth's interior, such as in subduction zones, mid-ocean ridges, and hotspots. However, it remains challenging to solve ... -
Exploring the use of blue mussel silage and fermented sugar kelp as low trophic marine resources in the Atlantic salmon (Salmo salar L.) diet
(Doctoral thesis, 2024-09-25)Havbrukssektoren er i rask vekst og er forventa å bidra med meir mat frå havet til den globale matforsyninga. Berekraftig vekst i fiskeoppdrett er avhengig av å finne nye fôringrediensar som har potensiale for oppskalering ... -
Volcanic activity and temporal evolution of ultraslow-spreading ridges
(Doctoral thesis, 2024-09-05)Det overordnede målet med denne studien har vært å øke vår forståelse av vulkansk aktivitet langs jordens ultrasakte sprederygger. Avhandlingen består av tre deler som sikter mot å: (I) Forstå den romlige og tidsmessige ... -
