There is actually a depth that submarines can hide in because the salinity/temperature trap/reflect sonar. There’s a special name for it that Destin at SmarterEveryDay covered during a deep dive on a US nuclear sub. It’s an amazing series for anyone looking for something to watch.

Another fun fact from that same video is we actually developed rescue devices that would explode at that special depth, and microphones around the world could triangulate where a downed pilot was.
