Attribution of multi-annual to decadal changes in the climate system: The Large Ensemble Single Forcing Model Intercomparison Project (LESFMIP)
(Journal article; Peer reviewed, 2022)Multi-annual to decadal changes in climate are accompanied by changes in extreme events that cause major impacts on society and severe challenges for adaptation. Early warnings of such changes are now potentially possible ... -
Automated Measurements of Whitecaps on the Ocean Surface from a Buoy-Mounted Camera
(Peer reviewed; Journal article, 2016-12)We quantify the percentage of sea surface covered by whitecaps from images taken by a non-stationary camera mounted on a moored buoy using an Adaptive Thresholding Segmentation (ATS) method and an Iterative Between Class ... -
Autonomous Ocean Turbulence Measurements Using Shear Probes on a Moored Instrument
(Peer reviewed; Journal article, 2014-02)An internally recording, autonomous instrument has been tested for measurements of ocean turbulence from a mooring line. Measurements were made at a single level in the water column, but for an extended period of time, at ... -
Avansert styringssystem for optimalisering av energilagring i distribusjonsnett
(Master thesis, 2019-01-17)I distribusjonsnettet har det lenge blitt opererert med tradisjonell nettutbygging for handtering av kapasitetsproblem eller spenningsproblem. Med stor vekst i tal el-bilar, meir energikrevjande apparat, samt befolkningsvekst ... -
Avvik mellom estimert og faktisk energiproduksjon for småkraftverk
(Master thesis, 2016-06-01)I denne oppgaven har jeg sett på årsakene til avviket mellom estimert og faktisk energiproduksjon for tre av kraftverkene som Småkraft AS sammen med grunneier har hatt i drift i 8-9 år. Kraftverkene jeg har sett på er Ytre ... -
Barents Sea ice cover reflects Atlantic inflow
(Working paper, 2011)The recent Arctic winter sea-ice retreat is most pronounced in the Barents Sea. Using available observations of the Atlantic inflow to the Barents Sea and results from a regional ice-ocean model we assess the role of ... -
Baroclinic Instability in the West Spitsbergen Current
(Peer reviewed; Journal article, 2011-07-15)Baroclinic instability in the West Spitsbergen Current is investigated, based on data from an array of current meter moorings along 78.83oN, across the deeper (1000-2400 m) section of the continental slope west of Svalbard. ... -
Barotropic instability in the West Spitsbergen Current
(Peer reviewed; Journal article, 2010-07-24)Barotropic instability in the shoreward branch of the West Spitsbergen Current is investigated on the basis of data from an array of current meter moorings along 78.83°N, across the upper continental slope and shelf break ... -

Batterilading i hybride fremdriftssystemer ved hjelp av tapsenergi fra forbrenningsmotoren
(Master thesis, 2017-06-23)In a time when emission standards are getting stricter, the search for more environmentally friendly propulsion is more relevant than ever. Hybridization and electric propulsion has, thus, become more common in some sectors, ... -
Bedymo: A combined quasi-geostrophic and primitive equation model in σ coordinates
(Journal article; Peer reviewed, 2022)This paper introduces the Bergen Dynamical Model (Bedymo), an idealized atmospheric circulation model, which combines the quasi-geostrophic approximation and the hydrostatic primitive equations into one modelling framework. ... -
Benefit of vertical localization for sea surface temperature assimilation in isopycnal coordinate model
(Journal article; Peer reviewed, 2022-12-15)Sea surface temperature (SST) observations are a critical data set for long-term climate reconstruction. However, their assimilation with an ensemble-based data assimilation method can degrade performance in the ocean ... -
Benguela Niños: Observations and Modelling
(Master thesis, 2004)A numerical ocean model for the South Atlantic was used to study the 1995 Benguela Niño in order to learn about the underlying forcing mechanisms of the phenomenon. By comparing observations and model output, it was found ... -
Best Practice Data Standards for Discrete Chemical Oceanographic Observations
(Journal article; Peer reviewed, 2022)Effective data management plays a key role in oceanographic research as cruise-based data, collected from different laboratories and expeditions, are commonly compiled to investigate regional to global oceanographic ... -
Bias correction of operational storm surge forecasts using Neural Networks
(Journal article; Peer reviewed, 2024)Storm surges can give rise to extreme floods in coastal areas. The Norwegian Meteorological Institute (MET Norway) produces 120 h regional operational storm surge forecasts along the coast of Norway based on the Regional ... -
Bifurcation Points for Tropical Cyclone Genesis and Intensification in Sheared and Dry Environments
(Journal article; Peer reviewed, 2023)The combination of moderate vertical wind shear (VWS) and dry environments can produce the most uncertain scenarios for tropical cyclone (TC) genesis and intensification. We investigated the sources of increased uncertainty ... -
The BLLAST field experiment: Boundary-Layer late afternoon and sunset turbulence
(Peer reviewed; Journal article, 2014-10-16)Due to the major role of the sun in heating the earth's surface, the atmospheric planetary boundary layer over land is inherently marked by a diurnal cycle. The afternoon transition, the period of the day that connects the ... -
Boosting effect of strong western pole of the Indian Ocean Dipole on the decay of El Niño events
(Journal article; Peer reviewed, 2024)The Indian Ocean Basin (IOB) mode is believed to favor the decay of El Niño via modulating the zonal wind anomalies in the western equatorial Pacific, while the contribution of the Indian Ocean Dipole (IOD) mode to the ... -
Bottom melting of Arctic Sea Ice in the Nansen Basin due to Atlantic Water influence
(Master thesis, 2016-05-24)The hydrographic situation for a region north of Svalbard is investigated using observations from the Norwegian Young Sea Ice Cruise (N-ICE2015). Observations from January to June 2015 are compared to historical observations ... -
A brief history of climate – the northern seas from the Last Glacial Maximum to global warming
(Peer reviewed; Journal article, 2014-12)The understanding of climate and climate change is fundamentally concerned with two things: a well-defined and sufficiently complete climate record to be explained, for example of observed temperature, and a relevant ...
