  • Mesoscale Eddies Are Oases for Higher Trophic Marine Life 

    Godø, Olav Rune; Samuelsen, Annette; Macaulay, Gavin J.; Patel, Ruben; Hjøllo, Solfrid Sætre; Horne, John; Kaartvedt, Stein; Johannessen, Johnny A. (Public Library of Science, 2012-01-17)
    Mesoscale eddies stimulate biological production in the ocean, but knowledge of energy transfers to higher trophic levels within eddies remains fragmented and not quantified. Increasing the knowledge base is constrained ...
  • 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, ...
