As others have already said, great whites have been around here much longer than I've been diving. Of course there are places off Catalina that I don't dive... like the sea lion hauling ground at the East End.
My only concern with respect to them now is the poor visibility. If diving in waters with normal (40-50+ ft) visibility I don't worry about GW's while I'm under water and a bit when I'm at the surface. However with the poor visibility the past few months (10 ft yesterday), I don't feel as comfortable diving in Whitey's territory.
John- I wonder if the increase in GW sightings of our coast is related to the poor visibility in the surface waters. I understand a normal cruising depth is in the 100-150 ft range. Could the very poor surface visibility be driving them upwards in the water column so they can see their prey, or does their perception of electrical fields dominate?
