Abstract
Data on the dynamics of bottom currents along the western coast of the Middle Caspian are given. The contributions of the mean kinetic energy of currents and the energy of perturbation to the total energy of currents are shown at different space and time scales of variations and for different seasons of the year. The results of studies are based on experimental data collected by CTD sounding of water mass, measuring currents with the use of Potok-M instruments, ADCP Doppler acoustic current meters in the regime of sounding and towing, as well as stationary measurements at submerged buoy stations.
