3D seismic investigation of fluid migration and fluid accumulation related to natural seeps in the Sørvestsnaget Basin, SW Barents Sea
(Mastergradsoppgave; Master thesis, 2025-01-27)This master thesis examines the intricacies of fluid migration, gas seep areas, and fault dynamics in the southwestern Barents Sea. Acoustic evidence, such as pockmarks and gas flares, indicates active fluid movement within the below seabed sedimentary structures, such as clinoforms and the Upper Regional Unconformity (URU). Challenging lowermost reaches of gas chimneys, obscured by acoustic masking, ... -
The future Barents Sea—A synthesis of physical, biogeochemical, and ecological changes toward 2050 and 2100
(Journal article; Tidsskriftartikkel; Peer reviewed, 2025-02-21)The Barents Sea is a hotspot for ongoing Arctic climate change, manifested in a rapid warming of the ocean and the atmosphere and a strong decline of the winter sea-ice cover. These changes in the physical environment have large consequences for marine ecosystems, including commercial fish populations. In a warmer future climate, both physical and ecological changes are expected to intensify. ... -

Empirical Study and Modelling of Sea-Spray Parameters for Robust Marine Icing Estimation
(Doctoral thesis; Doktorgradsavhandling, 2025-03-20)Sea-spray icing poses a significant risk to maritime operations in Arctic and sub-Arctic regions, threatening the stability, safety, and efficiency of vessels and offshore structures. Current icing estimation models are constrained by limited data and are often tailored to specific vessels or structures. A critical challenge lies in accurately estimating spray flux, which is the amount of water ... -
Leveraging synergies between UAV and Landsat 8 sensors to evaluate the impact of pale lichen biomass on land surface temperature in heath tundra ecosystems
(Journal article; Tidsskriftartikkel; Peer reviewed, 2025-03-01)Pale terricolous lichens are a vital component of Arctic ecosystems, significantly contributing to carbon balance, energy regulation, and serving as a primary food source for reindeer. Their characteristically high albedo also impacts land surface temperature (LST) dynamics across various spatial scales. However, remote sensing of lichens is challenging due to their complex spectral signatures and ... -

Impact of Gut Microbiome Modulating Interventions on Fecal Metabolome of Infants: A Systematic Review and Quality Assessment
(Journal article; Tidsskriftartikkel; Peer reviewed, 2025-02-27)The development of the gut microbiome in infancy is a vulnerable process that may be perturbed by antibiotics or supported by probiotics. Although effects of these “biotics” have been well-studied through DNA sequencing, it remains unclear how the resulting compositional changes affect the microbiome metabolic functions. Additionally, limits in method standardization require careful quality assessment ... -
Circulating endogenous sex steroids and risk of differentiated thyroid carcinoma in men and women
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-02-15)Thyroid cancer (TC) is substantially more common in women than in men, pointing to a possible role of sex steroid hormones. We investigated the association between circulating sex steroid hormones, sex hormone binding globulin (SHBG) and the risk of differentiated TC in men and women within the European Prospective Investigation into Cancer and nutrition (EPIC) cohort. During follow-up, we identified ... -
Evaluating the efficacy of endotracheal and intranasal epinephrine administration in severely asphyxic bradycardic newborn lambs: a randomised preclinical study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-09-04)Objective - Intravenous epinephrine administration is preferred during neonatal resuscitation, but may not always be rapidly administered due to lack of equipment or trained staff.

Parameter estimation for the weibull general log-linear model in accelerated life testing
(Journal article; Tidsskriftartikkel; Peer reviewed, 2025)Uncertainty is commonly present in accelerated life test (ALT) data. The combination of a general log-linear model with a statistical distribution model—using the Weibull distribution in this paper—allows for addressing both multiple operational factors and uncertainty within a single model. This paper interprets the Weibull General Log-Linear (WGLL) model from the ALT perspective. Two parameter ... -
Autonomous hunter-gatherer children in hierarchical schools: a review of the literature from the global South
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-09-20)We recently conducted a review of the literature regarding hunter-gatherer children’s schooling experiences in the global South (Ninkova et al 2024). In this research note, we highlight one central finding of our review: that the autonomy granted to hunter-gatherer children determines their participation in school. Children decide for themselves whether they will attend. Children also decide for ... -
