The main areas of research

• Theory of sound waves propagation with regard to the 3D structure of water masses and ocean floor rough
• Acoustic monitoring of water mass dynamics in the Arctic Ocean
• Numerical modeling of sound propagation in the ocean
• Acoustic tomography of the ocean
• Experiments on sound propagation, dispersion and reflection in various hydrological conditions

Estimates of auto-correlation of noise of natural origin for averaging times of
20 mins, 1 hour, 8 hours and 75 hours. Crosses mark the dispersion times,
calculated from the climatic profile of the speed of sound
