  • Observed anomalous atmospheric patterns in summers of unusual Arctic sea icemelt 

    Knudsen, Erlend Moster (WileyAmerican Geophysical Union, 2015-04-16)
    The Arctic sea ice retreat has accelerated over the last decade. The negative trend is largest in summer, but substantial interannual variability still remains. Here we explore observed atmospheric conditions and feedback ...

  • 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 ...

  • 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 Small-Scale Topography on Dense Plumes, with a Special Focus on the Filchner Overflow Plume 

    Darelius, Elin (The University of Bergen, 2007-10-05)
    Doctoral thesis
  • On the nature of the factors that control spring bloom development at the entrance to the Barents Sea and their interannual variability 

    Olsen, Are; Johannessen, Truls; Rey, Francisco (Taylor & Francis, 2003-12)
    Analysis of data obtained by the Institute of Marine Research, Norway, at their regular surveys of the Fugløya-Bjørnøya section, between the northern tip of Norway and Bear Island, has allowed for an identification of the ...

  • On the Nordic Seas’ role in the Atlantic Meridional Overturning Circulation 

    Iovino, Doroteaciro (The University of Bergen, 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 ...

  • On the potential of 230Th, 231Pa, and 10Be for marine rain ratio determinations: A modeling study 

    Heinze, Christoph; Gehlen, M.; Land, C. (American Geophysical Union, 2006-06-16)
    The global distributions of the radionuclides 230Th, 231Pa, and 10Be are simulated with a biogeochemical ocean general circulation model. Sensitivity experiments for changes in the composition of the particle composition ...
