The Polar Front in the northwestern Barents Sea: structure, variability and mixing
(Journal article; Peer reviewed, 2024)In the northwestern Barents Sea the warm and salty Atlantic Water meets the cold and fresh Polar Water, forming a distinct thermohaline front, the Barents Sea Polar Front. Here we present the structure of the front, its ... -
On the importance of the humidity flux for the surface mass balance in the accumulation zone of the Greenland Ice Sheet
(Journal article; Peer reviewed, 2024)It is highly uncertain how the humidity flux between the snow surface and the atmosphere contributes to the surface mass balance (SMB) of the interior Greenland Ice Sheet (GrIS). Due to sparse observations, evaluations of ... -
Causal Links Between Sea-Ice Variability in the Barents-Kara Seas and Oceanic and Atmospheric Drivers
(Journal article; Peer reviewed, 2024)The sea-ice cover in the Barents and Kara Seas (BKS) displays pronounced interannual variability. Both atmospheric and oceanic drivers have been found to influence sea-ice variability, but their relative strength and ... -
Sources of low-frequency variability in observed Antarctic sea ice
(Journal article; Peer reviewed, 2024)Antarctic sea ice has exhibited significant variability over the satellite record, including a period of prolonged and gradual expansion, as well as a period of sudden decline. A number of mechanisms have been proposed to ... -
An analysis of air-sea gas exchange for the entire MOSAiC Arctic drift
(Journal article; Peer reviewed, 2024)Sea ice cover influences the generation of surface ocean turbulence in ways that sometimes enhance, but mostly inhibit air-water gas exchange. Inhibition happens as ice cover reduces wind fetch, enhancement occurs when ... -
Enriched local convenience foods with two different small pelagic fish species increases the nutritional value without compromising taste
(Journal article; Peer reviewed, 2024)Cereals and their derived products are important dietary sources for humans but are mostly deficient in protein and several micronutrients. To increase the nutrient content of rice and wheat flour-based recipes, nutrient-dense ... -
Enhancing Wind Resource Predictability for Power Generation Based on NORA3 Hindcast Data
(Master thesis, 2024-12-19)The rising global energy demand, coupled with the urgent need to fully address climate change, has driven a critical shift from fossil fuels—still accounting for 80% of energy consumption in 2022—to renewable energy sources. ... -
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 ... -
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 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 ... -
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 ...
