A new modular instrumentation for meso-scale ocean acoustic tomography (OAT) has been developed for basin scale studies. The new instrument consists of a wide-band unlimited depth acoustic source, a high-efficiency class-D power amplifier, a programmable multifunction receiver, a long baseline positioning system, and a low-power, high-stability clock. In parallel with this development, a 1-gigabyte storage capacity autonomous receiver, which is able to work in various frequency bands, has also been developed. Fully compatible with the acoustic source, it can be used for standard OAT experiments.
