Characterization, calibration and optical performance of ocean light instruments and the legal background for deployment in the Arctic
(Doctoral thesis; Doktorgradsavhandling, 2025-09-19)While commercial light instruments can measure high and medium light intensities, there are few that can capture the low light conditions, consisting of light from moon, stars and aurora, that prevail during the (polar) night. In the ocean, light intensities are even lower because of the high absorption of water, optically significant constituents and phytoplankton. In polar regions, snow and sea ... -
Echoes of the Past: Finding the Secrets of Ancient Ecosystems using SedaDNA
(Doctoral thesis; Doktorgradsavhandling, 2025-09-19)Using sedimentary ancient DNA (sedaDNA) we can reconstruct past ecosystems and investigate biotic and abiotic drivers of ecosystem change. Mammalian sedaDNA is more challenging to obtain so we developed a dual human DNA blocking strategy to amplify more rare mammalian taxa. We then applied mammalian and plant sedaDNA metabarcoding to a Late Pleistocene (19 – 15 thousand years before present, ka BP) ... -
Ecological transitions in Arctic marine ecosystems. Macroalgal settlement, pelagic density, and fish community shifts associated with glacier retreat and Atlantification
(Doctoral thesis; Doktorgradsavhandling, 2025-09-16)The Arctic is warming at an unprecedented rate, driving severe changes in marine ecosystems. Glacier retreat, increased sedimentation rates, and reduced sea ice cover are reshaping Arctic fjords, where terrestrial, freshwater, and marine influences interact. Glacier fronts influence fjord biogeochemistry and marine ecosystems across multiple trophic levels, and localized effects of glacier retreat ... -
Dietary niches of phocid seals and predatory fishes in Kongsfjorden, Svalbard: Comparisons between co-occurring endemic Arctic and non-endemic species
(Doctoral thesis; Doktorgradsavhandling, 2025-10-09)Kongsfjorden in the Svalbard Archipelago has transitioned from an Arctic to an Atlantic state due to climate change. Warming of the fjord has led to sea ice reduction, glacial retreat and increasing abundances of Atlantic and boreal species. This process is called Atlantificaiton and is a cause for concern for Arctic endemic species native to Kongsfjorden. In this thesis, dietary niches and feeding ... -
Monitoring herbivore–environment relationships in a changing Arctic landscape
(Doctoral thesis; Doktorgradsavhandling, 2025-09-05)Arctic herbivores face a rapidly changing environment, impacting their habitat use and food resources. Understanding the extent and future impact of suitable habitats is crucial. However, studying herbivore-environment relationships in the Arctic is challenging due to vast distances, remoteness, and landscape heterogeneity. Remote sensing tools like GPS collars, wildlife cameras, drones, and satellites ... -
Lavere krav til allment evnenivå for befalsskolen – en bjørnetjeneste? En litteraturstudie og tematisk analyse om betydningen av allment evnenivå i militær seleksjon
(Master thesis, 2025)Denne masteroppgaven undersøkte betydningen av allment evnenivå (AE) i militær seleksjon, med utgangspunkt i forsvarssjefens beslutning i 2024 om å senke kravet til AE for opptak til befalsskolen. Det var interessant å undersøke om dette kunne påvirke kvaliteten på fremtidige militære ledere siden AE tidligere har vist høy prediktiv validitet for jobbprestasjon. Problemstillingen som ble belyst ... -
Explorations into the control of torpor arousal cycling in the Golden hamster (Mesocricetus auratus)
(Doctoral thesis; Doktorgradsavhandling, 2025-09-05)Endothermic animals have inherently high metabolic rates, granting advantages over ectotherms such as increased aerobic capacity, thermal independence, and niche expansion. However, the energy demands of endothermy increase disproportionately with decreasing body size. To mitigate these energetic costs, some endotherms employ metabolic flexibility strategies like torpor, a profound metabolic rate ... -
FishPoll – a serious game about sharing moving fish stocks under climate change
(Journal article; Tidsskriftartikkel; Peer reviewed, 2025-08-04)Climate change is driving shifts in fish stock distributions, creating challenges for transboundary fisheries governance and quota allocation. Traditional negotiation processes often fail to achieve consensus among stakeholders, leading to geopolitical tensions and unsustainable resource use. To address this, we introduce FishPoll, an innovative serious game designed to simulate the complexities ... -
Measuring cytokines in Eurasian tundra reindeer (Rangifer tarandus tarandus) with a bovine bead-based multiplex immunoassay and real-time PCR
(Journal article; Tidsskriftartikkel, 2025-06-18)Background - Reindeer (Rangifer tarandus tarandus) herding is based on access to seasonal pastures. Pastureland is, however, being lost and fragmented due to e.g. climate change, human activities, and predators, creating an increasing need for feeding and fencing. This alters disease occurrence, leading to a greater need for disease investigation tools. Knowledge of the activation of immune pathways ... -
Elucidating the knowledge, attitude, and stigma associated with tuberculosis: a community based descriptive study in Wau and Jur River, South Sudan
(Journal article; Tidsskriftartikkel; Peer reviewed, 2025-02-04)Background - Tuberculosis (TB) is a major public health problem in South Sudan. Inadequate knowledge, negative attitudes and perceived stigma may complicate the prevention efforts. This study describes knowledge, attitude, and stigma associated with TB among communities in Wau and Jur River, South Sudan.<p> <p>Methods - From March to May 2023, a cross-sectional study was conducted among 352 ... -
Stitching the Gap: Feedback as a Mechanism for Reinforcing Sustainable Fashion Consumption
(Journal article; Tidsskriftartikkel; Peer reviewed, 2025-07-10)This paper examines how positive feedback can elicit pride in sustainable fashion consumption and influence two key behavioral outcomes: willingness to buy sustainable fashion products and word-of-mouth endorsement. Drawing on framing theory and existing research on pride as a motivational emotion, we conducted two experimental studies with U.S.-based participants recruited via Prolific. In the first ... -
A Coastal Barometer to balance blue growth for northern Norway’s future
(Journal article; Tidsskriftartikkel; Peer reviewed, 2025)Growth of the blue economy will affect coastal ecosystems, altering human impacts, biodiversity, and ecosystem functions—transforming coastal societies in the process. The Coastal Barometer is intended to help find a good balance between growth, environmental conservation, and community well-being. -

Joint Russian Norwegian Arctic Fisheries Working Group (JRN-AFWG) Report 2025
(Research report; Forskningsrapport, 2025-07-01)On 30 March 2022 all Russian participation in ICES was temporally suspended. Althoughthe announcement of the suspension stressed the role of ICES as a “multilateral scienceorganization”, this suspension applied not only to research activities but also to the ICESwork providing fisheries advice for the sustainable management of fish stocks andecosystems. On 9 December 2024 Russia announced its intention ... -

Ecosystem metabolism and nitrogen budget of a glacial Fjord in the Arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2025-07-02)Fjords in the Arctic are changing rapidly due to multiple factors including increasing air temperatures, the influx of Atlantic Water (Atlantification), sea-ice loss, retreat of tidewater glaciers, increased freshwater discharges, pollution and tourism. Understanding how these changes affect ecosystem processes and functions and, thus, services to society is critical. Net Ecosystem Metabolism (NEM) ... -
Contrasting seasonal patterns in particle aggregation and dissolved organic matter transformation in a sub-Arctic fjord
(Journal article; Tidsskriftartikkel; Peer reviewed, 2025-01-31)Particulate (POM) and dissolved (DOM) organic matter in the ocean are important components of the Earth's biogeochemical cycle. The two are in a constant state of dynamic change as a result of physical and biochemical processes; however, they are mostly treated as two distinct entities, separated operationally by a filter. We studied the seasonal transition of DOM and POM pools and their drivers in ... -
