This work discusses the design and performance characteristics of a Digital Acoustic Telemetry System which incorporates current technology and is capable of data transmission at rates useful to ocean exploration and development gear. The design is based on a model of the high-frequency acoustic channel generally accepted in the ocean acoustic literature. The model describes the received sound field as a sum of reflections from various scatterers, and a `line-of-sight' propagation path is not necessarily present. Measurements are presented of the underwater acoustic channel used at frequencies centered at 50 kHz and at ranges up to 1 km. An attempt is made to measure parameters relevant to digital data communication and classify the channel based on these measurements.
