Spelling corrected. I'm curious......Not being educated in undersea phenomena, A BIG IF, that black box is supposed to be somewhere around 15,000 ft down in the ocean, what would the underwater pressure be on that black box?

Second, would it sink to the bottom or would pressure keep it suspended?

The boxes should be okay and if the pings are coming from 15,000 ft then they are more than likely on the bottom.
