Wind and wave extremes over the world oceans from very large ensembles
(WileyAmerican Geophysical Union, 2014-07)
Global return values of marine wind speed and significant wave height are estimated from very large aggregates of archived ensemble forecasts at +240 h lead time. Long lead time ensures that the forecasts represent independent ...
Some aspects of the work of V.W. Ekman
(Cambridge University Press, 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, ...
Microstructure Measurements from an Underwater Glider in the Turbulent Faroe Bank Channel Overflow
(American Meteorological Society, 2014-05)
Measurements of ocean microstructure are made in the turbulent Faroe Bank Channel overflow using a turbulence instrument attached to an underwater glider. Dissipation rate of turbulent kinetic energy « is measured using ...

Dispersion and abundance of salmon lice (Lepeophtheirus salmonis) in a Norwegian fjord system
(The University of Bergen, 2011-11-20)
Based on numerical results of currents from a high resolution fjord model, dispersion of salmon lice (Lepeophtheirus salmonis) in the Hardangerfjord has been modelled. The results show that salmon lice abundance in the ...
A diagnosis of warm-core and cold-core extratropical cyclone development using the Zwack–Okossi equation
(Royal Meteorological Society and Wiley-Blackwell, 2009)
In this study, the development of a warm-core and cold-core extratropical cyclone over North Atlantic is examined. The geostrophic relative vorticity tendency used to diagnose the development is calculated utilizing the ...
Carbon and oxygen fluxes in the Barents and Norwegian Seas : production, air-sea exchange and budget calculations
(The University of Bergen, 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 ...
Novel Tools for Research and Education in Seismology
(The University of Bergen, 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 ...
Effects of altitude and aerosol on UV radiation
(American Geophysical Union, 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 ...
Mechanisms for decadal scale variability in a simulated Atlantic Meridional Overturning Circulation
(Springer Verlag, 2011-06-25)
Variability in the Atlantic Meridional Overturning Circulation (AMOC) has been analysed using a 600-year pre-industrial control simulation with the Bergen Climate Model. The typical AMOC variability has amplitudes of 1 ...
