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
(Master thesis, 2018-06-21)The emission of greenhouse gases must be reduced to meet the objectives of The Paris Agreement. Geothermal heat pumps (GSHP) can reduce energy consumption and emission of greenhouse gases in the building sector. When an ... -

Observation and Simulation of Ice Tongues and Vortex Pairs in the Marginal Ice Zone
(Geophysical Monograph 85, Chapter, 1994)Recognizes the major advancements of the past decade in understanding the interactions among the polar oceans and global atmospheric and oceanic systems. This volume addresses the following topics: Polar Ocean Circulation ... -
Observational evidence for on-shelf heat transport driven by dense water export in the Weddell Sea
(Journal article; Peer reviewed, 2023)The transport of oceanic heat towards the Antarctic continental margin is central to the mass balance of the Antarctic Ice Sheet. Recent modeling efforts challenge our view on where and how the on-shelf heat flux occurs, ... -
Observational validation of the diffusive convection flux laws in the Amundsen Basin, Arctic Ocean
(Peer reviewed; Journal article, 2015-12)The low levels of mechanically driven mixing in many regions of the Arctic Ocean make double diffusive convection virtually the only mechanism for moving heat up from the core of Atlantic Water towards the surface. In an ... -
Observations of barotropic oscillations and their influence on mixing in the Faroe bank channel overflow region
(Peer reviewed; Journal article, 2013)Observations of hydrography, currents, and microstructure are presented together with sea surface height (SSH) patterns from concurrent satellite tracks to describe the subinertial oscillations in the region downstream of ... -
Observations of bridge stay cable vibrations in dry and wet conditions: A case study
(Journal article; Peer reviewed, 2021-04-01)The characteristics of wind- and rain-wind-induced vibrations of bridge stay cables are studied by using ambient vibrations records acquired on a cable-stayed bridge. Mean wind speed and wind-cable angle, as well as the ... -
Observations of brine plumes below Arctic sea ice
(Journal article, 2017)In sea ice, interconnected pockets and channels of brine are surrounded by fresh ice. Over time, brine is lost by gravity drainage and flushing. The timing of salt release and its interaction with the underlying water can ... -
Observations of energetic turbulence on the Weddell Sea continental slope
(Peer reviewed; Journal article, 2016-01-23)Turbulence profile measurements made on the upper continental slope and shelf of the southeastern Weddell Sea reveal striking contrasts in dissipation and mixing rates between the two sites. The mean profiles of dissipation ... -
Observations of highly regular oscillations in the overflow plume downstream of the Faroe Bank Channel
(Peer reviewed; Journal article, 2006-12-23)The Faroe Bank Channel (FBC) is the deepest connection between the Atlantic Ocean and the Nordic Seas. This work describes the dynamic properties of the plume of dense overflow water descending from the Faroe Bank Channel ... -
Observations of the Storfjorden overflow
(Peer reviewed; Journal article, 2003)The mixing and spreading of the Storfjorden overflow were investigated with density and horizontal velocity profiles collected at closely spaced stations. The dense bottom water generated by strong winter cooling, enhanced ... -
Observations of Turbulence at a Near-Surface Temperature Front in the Arctic Ocean
(Journal article; Peer reviewed, 2020)High-resolution ocean temperature, salinity, current, and turbulence data were collected at an Arctic thermohaline front in the Nansen Basin. The front was close to the sea ice edge and separated the cold and fresh surface ... -
Observed anomalous atmospheric patterns in summers of unusual Arctic sea icemelt
(Peer reviewed; Journal article, 2015-04-16)The Arctic sea ice retreat has accelerated over the last decade. The negative trend is largest in summer, but substantial interannual variability still remains. Here we explore observed atmospheric conditions and feedback ... -
Observed Changes in the Arctic Freshwater Outflow in Fram Strait
(Journal article; Peer reviewed, 2022)We have updated time series of liquid fresh water transport (FWT) in the East Greenland Current (EGC) in the western Fram Strait with mooring observations since 2015. Novel data have been used to correct earlier estimates ... -
Observed Seasonal Evolution of the Antarctic Slope Current System off the Coast of Dronning Maud Land, East Antarctica
(Journal article; Peer reviewed, 2024)The access of heat to the Antarctic ice shelf cavities is regulated by the Antarctic Slope Front, separating relatively warm offshore water masses from cold water masses on the continental slope and inside the cavity. ...
