      Submesoscale processes have a determinant role in the dynamics of oceans by transporting momentum, heat, mass, and particles. Furthermore, they can define niches where different phytoplankton species flourish and accumulate ...
    • 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 ...
