hi,
this is very nice idea, could you maybe also use more than 3 layers, simulating a termal layer who generates 2 sound channels for better sonar transmissions ?
maybe bad very close to surface, good after reaching 30 meters, moderate to bad between 50 and 100 meters, getting very good below 120 meters ?
...iam not shure if the SOFAR channel (short for Sound Frequency and Ranging channel) also transmit surface contacts.
