Abstract : In this paper the Passive Ocean Acoustic Tomography
(P-OAT) methodology is presented. This technique, avoiding the use of a
dedicated active sound source, estimates the sea water temperature
spatial distribution from the received noise emitted from ships of
opportunity. The feasibility of the proposed methodology has been
confirmed both by test-runs on semi-synthetic data and by the use of
real acoustic and environmental data collected during INTIMATE00
experiment performed on October 2000 in the Atlantic Ocean off the
Portuguese coasts.
