    • Ocean acidication in the Arabian Sea and the Red Sea - factors controlling pH 

      Omer, Waleed Mahmood M. Ahme (The University of Bergen, 2010-06-01)
      The CO2 increase in the ocean due to uptake of anthropogenic CO2 and the companying lowering of ocean pH is of major concern. In this study we investigated the variability of CO2 system parameters, focusing particularly ...

    • Ocean circulation and climate at the Eemian and last glacial inception 

      Born, Andreas (The University of Bergen, 2010-09-24)
      Combining a hierarchy of climate models of varying complexity with marine proxy data, we show that the North Atlantic surface circulation played an important role for the climate of the Eemian and the last glacial ...

    • Ocean internal wave spectra inferred from seismic reflection transects 

      Holbrook, W. Steven; Fer, Ilker (American Geophysical Union, 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 ...

    • Offshore Wind Farm Wake Effect on Stratification and Coastal Upwelling 

      Bakhoday Paskyabi, Mostafa (Elsevier Ltd., 2015-12-02)
      In this study, the interactions between an offshore wind farm, upper-ocean currents, and stratification are examined under shallow water conditions from a two-dimensional modeling standpoint. The modeling results from two ...

    • On Mixed Wind-Sea/Swell Conditions in the Open Ocean : Model and Radar-Observations 

      Aarnes, Ole Johan (The University of Bergen, 2005)
      Master thesis
    • On radar imaging of current features: 1. Model and comparison with observations 

      Kudryavtsev, Vladimir; Akimov, D.; Johannessen, Johnny A.; Chapron, B. (American Geophysical Union, 2005-07-22)
      A new radar imaging model of ocean current features is proposed. The simulated normalized radar cross section (NRCS) takes into account scattering from ‘‘regular’’ surfaces (by means of resonant Bragg scattering and ...

    • On radar imaging of current features: 2. Mesoscale eddy and current front detection 

      Johannessen, Johnny A.; Kudryavtsev, Vladimir; Akimov, D.; Eldevik, Tor; Winther, Nina Gjerde; Chapron, B. (American Geophysical Union, 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, ...

    • On the Influence of Latent and Sensible Heating for Maintaining Baroclinicity in the Gulf Stream Region 

      Dahl-Eriksen, Ståle (The University of Bergen, 2016-06-01)
      For the North Atlantic storm track to collocate with the ocean front, there has to be efficient restoring mechanisms for baroclinicity. The total diabatic heating is agreed to play the most dominant role, but whether ...
