• COASTWATCH´95: ERS 1/2 SAR detection of natural film on the ocean surface 

      Espedal, Heidi A.; Johannessen, Ola M.; Johannessen, Johnny A.; Dano, E.; Lyzenga, D. R.; Knulst, Johan (Peer reviewed; Journal article, 1998-10-15)
      Ocean mesoscale phenomena such as eddies and current convergence zones can often be seen in synthetic aperture radar (SAR) images due to characteristic patterns caused by natural film induced damping of the waves. Such ...
    • Satellite detection of natural films on the ocean surface 

      Espedal, Heidi A.; Johannessen, Ola M.; Knulst, Johan (Journal article; Peer reviewed, 1996-11-01)
      Natural films on the ocean surface influence air-sea fluxes of momentum, heat, and gas. It is therefore essential to be able to map the geographical extent and variability of such films to determine the resulting impact ...
