Abstract: A topside buoy system is disclosed for relaying a status of a diver between a monitoring station and a diver's wearable device and scuba tank pod. The communication may be carried by sonar signals underwater and may be transmitted by short-range communication methods through air. An application on the command station may display diver status information and may receive and transmit messages between the command station and the wearable device of the diver via the topside buoy. The diver location data may be determined relative to the topside buoy by determining a time delay of the sonar signal between the wearable device and the topside buoy, by a plurality of transducers configured to detect an angle from which the sonar signal originated, and a depth of the diver included in the sonar signal.
