[1] Maximum cross correlation (MCC) analysis of National Oceanic and Atmospheric
Administration (NOAA) advanced very high resolution radiometer (AVHRR) imagery of
the eastern Black Sea in late September 1999 has been used to reconstruct the velocity and
vorticity fields of the upper layer of the sea. Analysis revealed the large-scale dynamic
features characteristic of the Black Sea, namely the Rim Current, as well as the detailed
pattern of mesoscale vortical activity including meanders, eddies, and dipoles, which are
often observed on satellite visible, infrared, or sea color imagery. The dynamical character
of the pronounced dipole structure in the northeastern part of the Black Sea was
determined by comparison with satellite IR images, geostrophic velocities calculated on
the basis of conductivity-temperature-depth (CTD) casts performed and trajectories of six
