James Tuttle had only recently joined the diving
liveaboard MV Royal Evolution, operating between
Egypt and Sudan, as a dive guide, when he asked a
passenger who had been on similar trips to guide
him around inside the wreck of the Umbria, a wartime
Italian passenger liner scuttled in Port Sudan.
It was a night dive, and in the darkness, things did
not go as planned.
That passenger later wrote, "One wrong turn was
all it needed. My heart raced as I suddenly realized
the implications; that my lifeless body might only
be recovered long after I ran out of anything to
breathe. What an awful feeling it is when you realize
you are trapped inside a wreck at night. You can get
disorientated and lost so easily. Everywhere I looked
was familiar except that it seemed that whatever
direction I swam, I was confronted by an impenetrable
bulkhead.
"After three or four attempts at different routes
and seeing even our careful finning beginning to
stir up the sediment and reduce the visibility, my
anger at not finding what I was looking for began to
turn to fear -- the fear that we might never find our
way out. It was then that my heart began to climb
out of my chest. My buddy, James, seemed oblivious
to our predicament. He trusted me. I was responsible."

Those thoughts going through a diver's mind
could easily lead to panic and a fatal loss of control.
Thankfully, the diver was able to stop, regain control,
and think his way out of the predicament.
Panic kills too many divers -- even the most
experienced. We have written about diver panic
many times in the past. (https://goo.gl/eE97PB). Now, words from a famous cave diver prompt us to
consider it again.
Caving Into Panic
Cave diving, of course, is a highly technical sport,
where a diver is in the dark and with no direct
escape to the surface. Canadian Jill Heinerth manages
to undertake some of the most daunting cave
explorations. She was the first to dive the ice caves
on Antarctica and recently explored the caves of
Christmas Island. How does she do it? How does she
keep calm under pressure?
A recent feature in CBS News (British Columbia) by Lisa Johnson went some way toward explaining how
when she interviewed Jill Heinerth.
"I enter the water scared," said Heinerth. "It's
important for me to embrace that fear because that
tickling sensation on the back of my neck is self-preservation."
Inside a cave, which Heinerth describes as "swimming
through the veins of Mother Earth," many
things could go wrong. She could get lost, unable
to see because of silt clouding the water. She could
get stuck or run out of air to breathe, several kilometers
from escape. Rather than ignore these
risks, Heinerth says she imagines every one before
she dives.
"What's the worst that could happen today?" she
asks herself, before running through possible scenarios
like a checklist.
"I'm prepared. I have the technology. I know
what to do," she tells herself. "That way, when I actually enter the water, I've sort of freed my mind of all
of those negative thoughts."
When something scary does happen, Heinerth
says the first thing she does is try to control her
stress response.
"When your heart starts to race, you begin
breathing faster, and that's the last thing that I can
allow to happen to me underwater, with a limited
gas supply," said Heinerth. "I have to get control
over my breathing. I have to take a deep breath
and say to myself, 'Emotions, you won't serve me
now' and I have to send them away."
Of course, it takes a certain sort of person to
cope with cave conditions. Heinerth works within
the moment, as time seems to slow. Even if escape
is uncertain, she looks for the next best step. It's
something she learned to do during her early days
when she fended off an intruder who broke into
her apartment when she was a university student in
Toronto.
For a sport scuba diver, if you find yourself in a
tricky situation, before panic sets in, regain control. Think, plan and then act. Plan for the worst while
hoping for the best. Panic can lose you your life.
