North Atlantic 20th century multidecadal variability in coupled climate models: sea surface temperature and ocean overturning circulation
(The University of Bergen, 2011-06-06)
Output from a total of 24 state-of-the-art Atmosphere-Ocean General Circulation Models is analyzed. The models were integrated with observed forcing for the period 1850–2000 as part of the Intergovernmental Panel on ...
Numerical simulations of surface winds and precipitation in Iceland – Die zweite Aufgabe der theoretischen Meteorologie
(The University of Bergen, 2013-02-08)
Constraining the exchange through the strait of Bab el Mandab
(The University of Bergen, 2012-10-01)
The strait of Bab el Mandab connects the Red Sea with the Indian ocean via the Gulf of Aden. The mean circulation at the strait is a three-layered exchange. The circulation in the Red Sea is understood to be driven by the ...
Dynamics of a CO2-seawater interface in the deep ocean
(Sears Foundation for Marine Research, 2005)
A trough filled with liquid CO2 located at 3940 m depth has been used as a model system for CO2 deposition on the seafloor. To study the intrinsic properties of the interface between CO2 and seawater a wave maker was used ...
Rapid changes in the Subpolar Gyre based on an Ocean General Circulation Model
(The University of Bergen, 2013-06-03)
Data from the ocean component of the Norwegian Earth System Model has been analyzed for the period 1960-2008. Most attention is given to the Subpolar Gyre, which strength and spatial extensiveness is understood to have ...
Analysis of CryoSat’s radar altimeter waveforms over different Arctic sea ice regimes
(The University of Bergen, 2014-06-11)
Satellite altimetry has been used to derive information about sea ice thickness in the Arctic already for several decades. As part of the algorithms applied the shape of the radar signal is used to identify leads, the ...
The sensitivity of the present day Atlantic meriodinal overturning circulation to freshwater forcing
(American Geophysical Union, 2003-09-09)
Mounting evidence indicates that the Atlantic Meridional Overturning Circulation (AMOC) was strongly reduced during cold climate episodes in the past, possible due to freshwater influx from glacial melting. It is also ...
Pre-bloom dynamics of the Subpolar North Atlantic microbial food web
(The University of Bergen, 2013-02-18)
The aim of this study was to investigate the microbial planktonic food web in the pre- bloom period of the Subpolar North Atlantic Ocean. Through repeated visits to the Icelandic Basin, Norwegian Basin, and on the Shetland ...
Sensitivity of the marine biospheric Si cycle for biogeochemical parameter variations
(American Geophysical Union, 2003-09-06)
A systematic quantitative assessment of the marine silicon cycle is presented, based on a prognostic coupled water column-sediment global biogeochemical ocean general circulation model (HAMOCC). The resulting tracer ...
Vertical mixing in the marginal ice zone of the Barents Sea Spatial and temporal variation of oceanic turbulence - observations and numerical model experiments
(The University of Bergen, 2007-01-12)
Vertical mixing affects water mass modification, biological productivity, and chemical fluxes in the ocean, but its response to forcing and variability in time and space in seasonally ice-covered seas is inadequately known. ...
