The submersible interior is a shirtsleeve environment maintained at surface pressure. Like a spaceship, the sub’s atmosphere is fed oxygen at a measured rate while carbon dioxide is scrubbed by passing the air through a canister of lithium hydroxide. Emergency air can be supplied for days.
Communication with the Seward Johnson mother ship is via hydrophone.
