| Abstract: | On the basis of the data of the complex oceanographic experiment carried out in the course of the second Ukrainian Antarctic
expedition in March 1998, we study the structure and kinematics of waters in the region of the archipelago of Argentine Islands.
The regularities of thermohaline stratification of waters are discovered. We determine the most important environmental parameters
premoting the variability of hydrophysical fields on time scales varying from several days up to a week, analyse the data
of actual observations over the currents, and estimate the relative contribtions of diurnal and semidiurnal tidal waves to
the total dispersion of hydrophysical parameters of the environment. The residual currents are filtered out. We propose a
hypothesis about the mechanism of their formation. Various types of tidal currents are revealed and the directions of propagation
of diurnal and semidiurnal tidal waves are determined.
