Abstract :
The acoustic tomography experiment THETIS-2 was conducted in 1994 in the Western Mediterranean. Seven moored transceivers formed the tomography network. Their acoustic measurements were carried out with a single hydrophone deployed from drifting research vessel “Akademik S. Vavilov” (IORAS, Russia). A CTD survey was also made. An interthermocline eddy with a cold core was found during this experiment. Acoustic signals from the transceivers were recorded at 16 points within and around the eddy to study the feasibility of reconstruction of such mesoscale inhomogeneities by acoustic tomography means. The result of such reconstruction is presented
