This story dealt with the death of commercial hard hat diver, Edward Cossaboom. He slipped off the hull at about 80 fsw and descended to about 140 fsw before the tender realized what was happening and added enough air to his suit to compensate for the increased water pressure...So he went from 3.4 to 5.2 ata in an instant. This is the account on pp 46-47 of "Dark Descent" by Kevin McMurray. "But the pressure differential was too sudden and too great. It sent blood flooding into his heart and lungs, quickly exploding these organs...By the time he reached the bottom, the invading sea pressure had stripped the flesh from his bones. His skin and organs were pile-driven into...his copper diving helmet...The crew later reported that all that remained...was a jellyfish with a copper mantle and dangling canvas tentacles."
Good bedtime reading aye...
