Abstract(s)
This paper proposes an innovative concept that responds to the requirements of acoustic
REA as the integration between a network of sophisticated Acoustic-Oceanographic Buoys
(AOB) and online ocean properties inversion algorithms. A prototype of the system, in-
cluding one sonobuoy and a preliminary version of the inversion code, was tested at sea
during the MREA'03 sea trial. The AOB is a light acoustic receiving device that in-
corporates last generation technology for acquiring, storing and processing acoustic and
non-acoustic signals received in various channels along a vertical line array. During the
MREA'03 the AOB was deployed on a free drifting con guration. Source/receiver geom-
etry was estimated from the buoy's GPS. Online processing was made possible by wireless
transfer of the data and inversion was done in a range-dependent environment. Temper-
ature pro les inverted from acoustic signals in two frequency bands on near
