Using the concrete c(z) data (c=sound speed, z=depth) obtained in the
Mediterranean during the THETIS-2 experiment on board the ACADEMICIAN
SERGEY VAVILOV research vessel, the possibility of ray path identification
using nonstationary receiving are numerically investigated. Sufficient c(z)
data were obtained for numerical simulation of the sound propagation along
different acoustic routes. Sensitivity of different rays paths to errors caused
by the erroneous determination of depth and distance is analyzed. The
possibility of using the data obtained from the research vessel for ocean
acoustic tomography is discussed.
