The Aussies aren’t the only ones who have lost
divers of late. Two Colorado women in Cozumel
disappeared February 1 from the Punta Tunich
dive site. Janie McKibbon, 52, and Regena Hale,
50, both novice divers, were last seen at about 40'
when they gave a thumbs-up sign to their Dive
Paradise instructor and began to surface. When they didn't appear, he
radioed for help, and Mexican navy boats, aircraft, and 50 private vessels
mounted a full-scale search but failed to turn up any sign of the women.
Though the reef at Punta Tunich is between 40 and 60 feet, it’s
adjacent to a shelf that drops to over 1000. And the undertow there has
earned divers’ respect; “If you get caught in that undertow,’’ Dive Paradise’s
instructor said, “it’ll drag you right out.’’ The currents that day were described
as “off and on and changing.” Reader Gary Nagel, who returned from
Cozumel just after the accident, reported that on the date the divers disappeared,
“winds from the West drove the current to extremes.” He also
reported the death of another diver from air embolism the previous day.
We wrote about Cozumel currents a few years back after a spate of
disappearances. Divers who’d been in their grip described a choppy sea
pockmarked by 30-100' areas of placid water surrounded by whitecap
rapids. At times a tornado-like funnel swirled in the middle of the calm.
Since changes in tide and the mixture of warm and cool water are reportedly
responsible, the problem isn’t seasonal.
It is, however, frightening, and staying calm at such a time can be as
challenging as the currents themselves. If you get caught in a downwelling or
upwelling, however, don’t panic. Instead of struggling against the powerful
current, swim out at an angle so you don’t fight its full power. In a powerful
undertow, simply inflating your BC may not precipitate an ascent. Instead,
drop your weight belt, inflate your BC, and then try to ascend. Should you
begin to ascend too rapidly, spread eagle to slow the rate.
Even better, of course, is examining the surface before entry and
looking for the telltale signs of raging currents. If you see them, stay out of
the water.
