On radar imaging of current features: 2. Mesoscale eddy and current front detection
(Peer reviewed; Journal article, 2005-07-22)The surface signatures of meandering fronts and eddies have been regularly observed and documented in synthetic aperture radar (SAR) images. Wave-current interactions, the suppression of short wind waves by natural film, ... -
Modeling the middle Pliocene climate with a global atmospheric general circulation model
(Peer reviewed; Journal article, 2005-07-27)A new climate simulation for the middle Pliocene (ca. 3 Ma BP) is performed by a global grid-point atmospheric general circulation model developed at the Institute of Atmospheric Physics (IAP AGCM) with boundary conditions ... -
Disappearance of Pacific Water in the northwestern Fram Strait
(Journal article, 2005-07-28)Water of Pacific origin, entering the Arctic Ocean through the Bering Strait, exits the Arctic Ocean through the Canadian Archipelago and the Fram Strait. The amount and timing of Pacific Water export through these gates ... -
Ocean internal wave spectra inferred from seismic reflection transects
(Peer reviewed; Journal article, 2005-08-06)Internal waves affect many important dynamical processes in the ocean, but in situ observations of internal waves are infrequent and spatially sparse. Here we show that remote sensing of internal waves by marine seismic ... -
Tracer-derived transit time of the waters in the eastern Nordic Seas
(Peer reviewed; Journal article, 2005-08-25)The spatial-temporal distribution of the anthropogenic radionuclide 137Cs originating from nuclear bomb testing and the Sellafield reprocessing plant in the Irish Sea is simulated using a global version of the Miami Isopycnic ... -
One more step toward a warmer Arctic
(Peer reviewed; Journal article, 2005-09-09)This study was motivated by a strong warming signal seen in mooring-based and oceanographic survey data collected in 2004 in the Eurasian Basin of the Arctic Ocean. The source of this and earlier Arctic Ocean changes lies ... -
Atmospheric-driven state transfer of shore-fast ice in the northeastern Kara Sea
(Journal article, 2005-09-21)Frequencies of observed occurrences of shore-fast ice in the northeastern Kara Sea for each month during 1953–1990 reveal a multimodality of shore-fast ice extent in late winter and spring. The fast ice extent exhibits ... -
Turbulent diffusion and transport from a CO2 lake in the deep ocean
(Journal article, 2005-09-21)If liquid CO2 is stored as a dense ‘‘lake’’ on the deep ocean floor, it is expected to dissolve in seawater. Ocean currents and turbulence can increase the net rate of CO2 release by several orders of magnitude compared ... -
Effects of simulated natural variability on Arctic temperature
(Journal article, 2005-09-23)A five-member ensemble with a coupled atmospheresea ice-ocean model is used to examine the effects of natural variability on climate projections for the Arctic. The individual ensemble members are initialized from a 300 ... -
Water mass modification in an Arctic fjord through cross-shelf exchange: The seasonal hydrography of Kongsfjorden, Svalbard
(Journal article, 2005-12-08)Kongsfjorden and the West Spitsbergen Shelf is a region whose seasonal hydrography is dominated by the balance of Atlantic Water, Arctic waters, and glacial melt. Regional seasonality and the cross-shelf exchange processes ... -
Stratification and circulation in Sognefjorden
(Master thesis, 2006)The winter time stratification and circulation above sill depth in Sognefjorden is studied from CTD and ADCP data from February 2002-2004. The year to year variability in distribution of temperature and salinity has been ... -
Klimaeffektar av redusert arktisk sommarisdekke: ein modellstudie

Vêrskipstasjonen MIKE og modellen MICOM - ei samanlikning av observasjonar og modellresultat over 55 år
(Master thesis, 2006)Observasjonar frå MIKE viser ein varm og salt periode som starta i år 2000, og i 2004 vart dei høgste, observerte temperatur og salt verdiane for den atlantiske kjernen registrert her. Oppvarminga nede i djupet pågår stadig, ... -

Some aspects of the work of V.W. Ekman
(Journal article, 2006-01)The climatic conditions in theArctic, and observations of the wind-induced drift of ice made in connexion with Fridtjof Nansen’s Fram expedition, led to the discovery 100 years ago by Vilhelm Bjerknes’ pupil, V.W. Ekman, ... -
Effects of altitude and aerosol on UV radiation
(Journal article, 2006-01-10)Measurements of erythemally weighted UV radiation during about 600 days at different sites in Bolivia and Germany ranging from 550 to 5240 m above sea level have been used to derive the altitude effect AE under cloud-free ... -
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 ... -
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 ... -
