They have some type of radio link that works at depth for simple texts messages, but they have to be right above it.

- mcpackieh 3y agoThat doesn't seem right, do you have any source? VLF wouldn't stand a chance of reaching that deep and ELF requires extremely large antenna to work. More likely they were using some form of underwater acoustic communication, sending and receiving data through sound instead of radio waves.
- venusenvy47 3y agoI don't have information about the type of communication link. I shouldn't have called it a radio link. Acoustic probably makes more sense. It was something very slow, so that sounds right.
