Maybe a stupid question, but I've been wondering if the sub would surface without power? Or does the pressure at these depths override any buoyancy?

I think density of water increases with lower temperatures and increased pressure so if it is buoyant on surface I think it should be bouyant at depth. Not sure though.
When Cameron’s team designed his sub he had a failsafe to corrode off the ballast and self return to surface in the event of failure of various systems.
