Ocean horror games

Horror games set at sea or under it: drifting ships, oil rigs over the North Sea, research stations on the sea floor and submarines sent into depths nobody has mapped. The water is the threat as much as anything in it. You cannot see far, help is miles away, and whatever rises from below has been waiting there a long time.
