The northern European shelf as an increasing net sink for CO2
(Journal article; Peer reviewed, 2021)We developed a simple method to refine existing open-ocean maps and extend them towards different coastal seas. Using a multi-linear regression we produced monthly maps of surface ocean fCO2 in the northern European coastal ... -
Northern Hemisphere storminess in the Norwegian Earth System Model (NorESM1-M)
(Journal article, 2014-12-16)Metrics of storm activity in Northern Hemisphere high- and midlatitudes are evaluated from historical output and future projections by the Norwegian Earth System Model (NorESM1-M) coupled global climate model. The European ... -
Northern Hemisphere Urban Heat Stress and Associated Labor Hour Hazard from ERA5 Reanalysis
(Journal article; Peer reviewed, 2022)Increasing surface air temperature is a fundamental characteristic of a warming world. Rising temperatures have potential impacts on human health through heat stress. One heat stress metric is the wet-bulb globe temperature, ... -
Norway's marine and terrestrial climate mapped with dynamical downscaling
(Doctoral thesis, 2022-06-20)Long-term numerical reconstructions on high spatial resolution of past weather are essential tools for studies of the local climate and climate extremes. The focus of this thesis has been to resolve the wind, precipitation, ... -
Norwegian Atlantic Slope Current along the Lofoten Escarpment
(Journal article; Peer reviewed, 2020-06)Observations from moored instruments are analyzed to describe the Norwegian Atlantic Slope Current at the Lofoten Escarpment (13∘ E, 69∘ N). The data set covers a 14-month period from June 2016 to September 2017 and resolves ... -
Norwegian offshore wind power—Spatial planning using multi-criteria decision analysis
(Journal article; Peer reviewed, 2023)The Norwegian government recently agreed on the goal 30by40, which involves opening Norwegian offshore areas to host 30 GW of installed wind power by 2040. We address this goal by presenting a first mapping of wind power ... -
A novel approach to computing super observations for probabilistic wave model validation
(Peer reviewed; Journal article, 2019-07)In the field of wave model validation, the use of super observations is a common strategy to smooth satellite observations and match the simulated spatiotemporal scales. An approach based on averaging along track is widely ... -
Novel Tools for Research and Education in Seismology
(Master thesis, 2002)It’s first part describes the noise performances of an inexpensive instrument for seismic data collection; the geophone-based seismograph used in the SEIS-SCHOOL network and now called Cossac Ranger. The analysis of its ... -
A Numerical approach for Ship Energy Analysis
(Master thesis, 2018-06-20)This master´s thesis has focused on energy analysis of ships and ship designs by developing a tool and a method for numerical analysis for evaluation of emissions, efficiency and costs. The overall focus has been on making ... -
A numerical estimate of the tidal energy in the Lofoten area
(Master thesis, 2014-05-28)In the following study the energy potential associated with tidal energy will be investigated. A depth integrated model based on the Navier Stokes equations and the continuity equation will be applied to simulate the tides ... -
Numerical Investigation of a Radially Cooled Turbine Guide Vane Using Air and Steam as a Cooling Medium
(Master thesis, 2021-06-01)Gas turbine performance is closely linked to the turbine inlet temperature, which in turn is limited by the turbine guide vanes ability to withstand the massive thermal loads. To improve the efficiency in modern high-temperature ... -
Numerical Investigation of the Use of Nanofluid in a Photovoltaic Thermal System
(Master thesis, 2022-06-01) -
Numerical modelling of the sub-surface melting of marine-terminating glaciers in Arctic fjords
(Master thesis, 2015-06-01)Submarine melting of glaciers terminating in fjords is likely to be of high importance regarding the total ice loss from ice sheets and ice caps and the resulting addition of freshwater to the ocean. Submarine melting ... -

Numerical Study of a Microturbine Combustor
(Master thesis, 2018-06-21)Microturbines are small-scale gas turbine engines with a power range of 20 to 500 kW, typically used for off-grid power generation or mechanical drive scenarios. The technology also shows potential in combination with ... -
A numerical study of transport and spreading of gases from natural analogues of gas-seepage through the seafloor
(Peer reviewed; Journal article, 2009-02)Natural leakages of CO2 are reported in the literature at mid ocean ridges and CH4 seepages in hydrocarbon rich ares. These could potentially serve as natural analogues of leakages from CO2 storages. In this study we have ... -
Numerical study on the hydrodynamic background in coastal aquaculture dominated regions and corresponding interactions in the Yellow Sea
(Doctoral thesis, 2022-01-07)The Yellow Sea is an important region for aquaculture in China as the main production area for shellfish and seaweed. The aquaculture organisms sometimes can be the major group in a local ecosystem. e.g., in the Sanggou ... -
Numerisk modellering av varmeoverskudd i grunnvarmeanlegg – Konsekvenser og forebyggende tiltak
