Atmospheric icing and meteorological variables: Full scale experiment and testing of models
(Doctoral thesis, 2005-04-15) -
Carbon and oxygen fluxes in the Barents and Norwegian Seas : production, air-sea exchange and budget calculations
(Doctoral thesis, 2007-08-17)This thesis focus on the carbon and oxygen fluxes in the Barents and Norwegian Seas and presents four studies where the main topics are variability of biological production, air-sea exchange and budget calculations. The ... -
Climate controlled mechanisms of subpolar North Atlantic carbon uptake
(Doctoral thesis, 2017-06-27)The North Atlantic is a key region for global climate variability. Earlier studies have shown changes in the large-scale circulation, air-sea heat and freshwater fluxes and the carbon cycle in the North Atlantic in relation ... -
Drag coefficient reduction at very high wind speeds
(Peer reviewed; Journal article, 2006-03-31)The correct representation of the 10-m drag coefficient for momentum (K10) at extreme wind speeds is very important for modeling the development of tropical depressions and may also be relevant to the understanding of other ... -
Effect of critical latitude and seasonal stratification on tidal current profiles along Ronne Ice Front, Antarctica
(Journal article, 2006-03-30)The ice front region of Ronne Ice Shelf lies near the critical latitude of the semidiurnal M2 tide, the principal tidal constituent in the southern Weddell Sea. Here the Coriolis frequency almost equals the M2 tidal ... -
En enkel gressvekstmodell utprøvd på Island og i Norge

Exchange of water masses between the southern Weddell Sea continental shelf and the deep ocean
(Doctoral thesis, 2018-06-13)The exchange of water masses between the shallow Weddell Sea continental shelf and the deep ocean is of climatic importance. Firstly, on-shelf transport of warm oceanic water masses, contributes to basal melting of ice ... -
Extreme winds in the Nordic Seas : polar lows and Arctic fronts in a changing climate
(Doctoral thesis, 2007-03-30) -
Inorganic Carbon and Water Masses in the Irminger Sea since 1991
(Peer reviewed; Journal article, 2017-02-17)The subpolar gyre region in the North Atlantic is a major sink for anthropogenic carbon. While the storage rates show large interannual variability related to atmospheric forcing, less is known about variability in the ... -
Irminger Sea deep convection injects oxygen and anthropogenic carbon to the ocean interior
(Peer reviewed; Journal article, 2016-10-27)Deep convection in the subpolar North Atlantic ventilates the ocean for atmospheric gases through the formation of deep water masses. Variability in the intensity of deep convection is believed to have caused large variations ... -
Mixing processes in the changing Arctic Ocean
(Doctoral thesis, 2017-08-11)The Arctic has undergone tremendous changes the last decades, including a strong decline in sea ice extent and thickness. The rapid pace of Arctic changes relative to the global changes are known as Arctic amplification, ... -
Modeling ocean processes below Fimbulisen, Antarctica
(Peer reviewed; Journal article, 2006-01-18)Model simulations of circulation and melting beneath Fimbulisen, Antarctica, obtained using an isopycnic coordinate ocean model, are presented. Model results compare well with available observations of currents and hydrography ... -
Ocean abyssal carbon experiments at 0.7 and 4 km depth
(Journal article, 2005)Observations from small-scale (20 to 90 litres) CO2 experiments conducted off the coast of California at 684 m depth and at 3942 m depth are discussed. In both experiments, when the seawater velocity was sufficiently strong, ... -
Ocean acidification in the subpolar North Atlantic: rates and mechanisms controlling pH changes
(Peer reviewed; Journal article, 2016-06-23)Repeated hydrographic sections provide critically needed data on and understanding of changes in basin-wide ocean CO2 chemistry over multi-decadal timescales. Here, high-quality measurements collected at twelve cruises ... -
Ocean storage
(IPCC Special Report on Carbon dioxide Capture and Storage, Chapter, 2005) -
On Mixed Wind-Sea/Swell Conditions in the Open Ocean : Model and Radar-Observations
(Master thesis, 2005) -
On the Nordic Seas’ role in the Atlantic Meridional Overturning Circulation
(Doctoral thesis, 2007-06-27)In the present climate, the North Atlantic thermohaline circulation (THC) plays a fundamental role in the global transport of heat at high latitudes. The response of the North Atlantic Ocean-Nordic Seas THC to surface ... -
Reconstructing the time history of the air-sea CO2 disequilibrium and its rate of change in the eastern subpolar North Atlantic, 1972–1989
(Peer reviewed; Journal article, 2006-02-18)This study determines the temporal changes of wintertime surface ocean partial pressure of CO2 (pCO2 SW) in the eastern subpolar North Atlantic (esNA) (50–64ºN; 32–10ºW) by using data of carbon-system parameters and ... -
Satellite monitoring of algal blooms in Norwegian coastal waters
(Doctoral thesis, 2006-02-23) -
Small-scale dynamics of the under-ice boundary layer
(Doctoral thesis, 2009-01-09)In ice covered polar regions, the interaction between ocean, ice and atmosphere is an important component in the complex climate system. Exchange of heat, mass and momentum occurs across the boundary layers, both in the ...
