The pressurised gas that saturation divers usually breathe may have given Lemons an additional chance. If you cool the brain to 20C (68F), you can get an hour.” If you lower the brain temperature down to 30C (86F), it can increase the survival time from 10 to 20 minutes. “If you reduce the temperature by 10 degrees the metabolic rate drops by a half to a third. “Rapid cooling of the brain can increase survival time without oxygen,” says Tipton. I remember being taken over by grief in some ways.” I knew I had a very small amount of gas on my back and my chances of getting out of it were almost non-existent. “I hit the sea bed on my back and was surrounded by an all-encompassing darkness. “I’m not sure I had a full handle on what was happening,” recalls Lemons. What life might be like in alien oceans.The real reason why sharks attack humans.Over the next 30 minutes at the bottom of the North Sea, Lemons would experience something that few people have lived to talk about: he ran out of air. Most crucially, his air supply had also vanished, leaving him with just six or seven minutes of emergency air supply. His link to the ship above was gone, along with any hope of finding his way back to it. One moment he was jammed against the metal underwater structure they had been working on and then he was tumbling backwards towards the ocean floor. While his colleagues remember the terrible noise of this lifeline breaking, Lemons himself heard nothing. This vital umbilical cord to the world above carried power, communications, heat and air to his diving suit 100m (328ft) below the surface of the sea. ![]() There was a sickening crack when the thick cable connecting Chris Lemons to the ship above him snapped. ![]()
