Ocean warming drives immediate mass loss from calving glaciers in the high Arctic
(Journal article; Peer reviewed, 2024)Glaciers in the Arctic have lost considerable mass during the last two decades. About a third of the glaciers by area drains into the ocean, yet the mechanisms and drivers governing mass loss at glacier calving fronts are ... -
Power in urban logistics: A comparative analysis of networks and policymaking in logistics sustainability governance
(Journal article; Peer reviewed, 2024)This article unpacks the power relations in urban logistics to understand why cities follow different policy pathways to sustainability. Drawing on the literature on power in sustainability transitions, we investigate key ... -
Dakar Niño under global warming investigated by a high-resolution regionally coupled model
(Journal article; Peer reviewed, 2024)In this study, we investigated interannual variability in sea surface temperature (SST) along the northwestern African coast, focusing on strong Dakar Niño and Niña events and their potential alterations under the RCP8.5 ... -
Observed Pathways and Interannual Variability of the Warm Inflow Onto the Continental Shelf in the Southern Weddell Sea
(Journal article; Peer reviewed, 2024)Model projections suggest that the continental shelf in the southern Weddell Sea may experience a shift from today's near-freezing temperature to a much warmer state, where warm water floods the shelf and basal melt rates ... -
Extreme wind events responsible for an outsized role in shelf-basin exchange around the southern tip of Greenland
(Journal article; Peer reviewed, 2024)The coastal circulation around Southern Greenland transports fresh, buoyant water masses from the Arctic and Greenland Ice Sheet near regions of convection, sinking, and deep-water formation in the Irminger and Labrador ... -
Modelling and validation of polycyclic aromatic hydrocarbons emissions from offshore oil production facilities
(Journal article; Peer reviewed, 2024)The development of numerical models for investigating the risks and impact caused by human activities to the marine environment is important. Herein, the recently developed ChemicalDrift Lagrangian dispersion model was ... -
Adaptive Covariance Hybridization for the Assimilation of SST Observations Within a Coupled Earth System Reanalysis
(Journal article; Peer reviewed, 2024)Ensemble data assimilation methods, such as the Ensemble Kalman Filter (EnKF), are well suited for climate reanalysis because they feature flow-dependent covariance. However, because Earth System Models are heavy ... -
Modelling the fate and transport of pollutants in the marine environment : Investigations of the emissions from shipping and offshore oil and gas production facilities
(Doctoral thesis, 2025-02-21)Denne avhandlingen beskriver en ny numerisk modell, ChemicalDrift, som er utviklet for å simulere spredning og skjebne av kjemikalier i marine miljøer. Modellens evner blir demonstrert gjennom to casestudier som ser på ... -
Wave measurements using open source ship mounted ultrasonic altimeter and motion correction system during the one ocean circumnavigation
(Journal article; Peer reviewed, 2024)This study reviews the design and signal processing of ship borne ultrasonic altimeter wave measurements. The system combines a downward facing ultrasonic altimeter to capture the sea surface elevation as a time series, ... -
Improving subseasonal forecast skill in the Norwegian Climate Prediction Model using soil moisture data assimilation
(Journal article; Peer reviewed, 2024)This study shows the importance of soil moisture (SM) in subseasonal-to-seasonal (S2S) predictions at mid-latitudes. We do this through introducing the Norwegian Climate Prediction Model Land (NorCPM-Land), a land reanalysis ... -
A versatile water vapor generation module for vapor isotope calibration and liquid isotope measurements
(Journal article; Peer reviewed, 2024)A versatile vapor generation module has been developed for both field-based water vapor isotope calibrations and laboratory-based liquid water isotope measurements. The vapor generation module can generate a stream of ... -
Sea-ice-loss slowdown modulates the sea surface salinification in the Kara-Laptev Seas since the 2008 summer
(Journal article; Peer reviewed, 2024)Recent studies have revealed the slowed Arctic sea-ice loss, but its climate effect on the ocean system remains unclear. By examining reanalysis datasets, we illustrate a paradoxical regime shift characterized by sustained ... -
Isotopic Fractionation during Sublimation of Low Porosity Ice
(Journal article; Peer reviewed, 2024)The magnitude of isotopic fractionation during sublimation of ice remains poorly constrained. Field and laboratory studies that span decades have persistently shown conflicting results. A better understanding of fractionation ... -
Scaling non-stationary turbulence during the afternoon and evening transition of the convective boundary layer
(Doctoral thesis, 2025-02-07)Turbulens, transport og blanding i det atmosfæriske grenselaget (ABL) er relevant for en rekke felt med stor samfunnsmessig betydning, som urban meteorologi, kontroll og varsling av luftkvalitet, landbruksmeteorologi og ... -
Warm Arctic-Cold Eurasia pattern helps predict spring wildfire burned area in West Siberia
(Journal article; Peer reviewed, 2024)Extreme wildfires have devastating impacts on multiple fronts, and associated carbon greatly heats the earth’s climate. Whether and how to predict wildfires becomes a critical question. In this study, we find that the ... -
Spatio-temporal averaging of jets obscures the reinforcement of baroclinicity by latent heating
(Journal article; Peer reviewed, 2024)Latent heating modifies the jet stream by modifying the vertical geostrophic wind shear, thereby altering the potential for baroclinic development. Hence, correctly representing diabatic effects is important for modelling ... -
Long-term changes in stratification and convection in the Nordic Seas : An observational perspective
(Doctoral thesis, 2025-01-21)I løpet av de siste tiårene har de Nordiske Hav gjennomgått en endring mot høyere temperatur og lavere tetthet. I Grønlandshavet ble den tyngste vannmassen i de Nordiske Hav dannet gjennom konveksjon som nådde helt til ... -
IEA Wind Task 49: Reference Site Conditions for Floating Wind Arrays
(Journal article; Peer reviewed, 2024)The commercial-scale deployment of floating offshore wind (FOW) projects is expected to take place in a diverse range of sites that may differ significantly from existing fixed-bottom projects. FOW farms are particularly ... -
Assessment of wind-damage relations for Norway using 36 years of daily insurance data
(Journal article; Peer reviewed, 2024)Extreme winds are by far the largest contributor to Norway’s insurance claims related to natural hazards. The predictive skills of four different damage functions are assessed for Norway at the municipality and national ... -
StormRisk: Linking Norwegian windstorms and damage, future risk and the feasibility of impact based forecasting
(Doctoral thesis, 2025-01-14)Vindstormer er blant de mest signifikante naturfarene i Norge, og kan påføre skade på infrastruktur og eiendom, inkludert boliger, industribygg og kraftlinjer. Pålitelige risikoanalyser av vindstormer og nøyaktige værmeldinger ...
