The presented data contain recordings of underwater acoustic transmissions collected from a field experiment whose goal was to evaluate the feasibility of in-band full-duplex acoustic communications in the underwater environment. The experiment was conducted in Lake Tuscaloosa in June 2021. Two boats, each equipped with an instrument line, were deployed for the experiment. For the local instrument line, the transducer was mounted 6 meters below the water surface. The receiving array was placed 7 meters below the transducer.
