Sam... so you know and dove with Ron, eh. He was a great SCUBA instructor. Even though I had been diving sporadically for about 8 years before I got certified, I learned a lot from him. I can just imagine him swimming back to the Golden Doubloon (which was, by the way, the boat that brought me to Catalina for my first ocean dives here back in the late 60's).
I'm not aware of an orca attack on a diver, but do seem to remember something about one chasing a human onto an ice flow, or was it a rocky pinnacle.
Orcas have been experiencing problems with their normal food sources in Arctic waters (they're now decimating sea otter populations up there), so perhaps they are moving south to take advantage of the increasing pinniped populations in our waters.
