Scuba diver dies off Rhode Island coast – CDNN report.
This guy was THE guy in scuba-diving. 60 years of age, he taught safe scuba techniques. He was diving at the wreck of the submarine U-853, some 37 meters underwater. He was with friends who were filming the wreck.
Seriously, at 37 meters, if he was doing a normal air dive, he would have had 11 minutes at that depth for a non-deco dive. I’m pretty sure he was on Nitrox to enable him to stay below longer.
Could it have been exertion? Or some cardiac problem?
