Guy, That sounds like something straight out of Jacques Cousteau! I wonder if anyone has ever filmed it underwater. If not, someone really should, Jo At 07:16 PM 7/28/2005 -0600, Guy wrote:
I was diving in a field of ice at a depth of 27 degrees Farenheit. Just moments before an unscheduled, uncontrolled dash to the surface because of a free flowing regulator and dry suit inflator valve, I had been watching my exhaust bubbles. At that temperature, the air bubbles would freeze and glaze over, and as the bubbles grew in size, they would break into a gazillion shimmering shards of ice crystals, only to reform and repeat the process. The larger shards of ice held the image of the sun, which was overhead. That was one of the coolest things I've ever seen. Of course, hitting the surface like a runaway polaris missle wasn't very cool at all... :( Doing surface intervals while floating under a star lit sky, rule!
