Hydrophysical fields, continuous in time and space, were reconstructed in the coastal region of the Black Sea (a western coast of the Crimea and a north-western
shelf of the Black sea) on the basis of the three-dimensional nonlinear hydrodynamic model and the observational data of temperature and salinity on the research
vessel "Experiment" from 16 to 22 of September, 2007. A sequential optimal interpolation of observational data of temperature and salinity was used as an assimilation
procedure. A real atmospheric forcing and a high resolution (horizontal grid similar to 1.6 x 1.6 km and 30 vertical layers from 1 m to 1300 m) were used in the
calculation. Mesoscale features of currents and thermohaline fields in the coastal zone of the Black Sea were investigated, the coastal upwelling in the Kalamitsky
Bay was reconstructed, registered in satellite observations. The influence of the assimilation of observational data on the accuracy of the calculated fields of
temperature and salinity was estimated.
