Seems to me that 2 people in an ambient submersible maintaining 30 feet and exhaling into an exhaust line would do better than 2 scuba divers swimming and enduring the cold.  Would that not be true? If you were not exhaling into an exhaust line, I'd venture to guess that the answer is somewhere around 3 cfm per person.
