In April, Dan Carlock of Santa
Monica, CA, was forgotten at sea
while diving off the Sun Diver out
of Long Beach. Carlock drifted
alone for five hours in 60-degree
water about seven miles offshore,
praying for his life before being
spotted by a Boy Scout aboard a
century-old tall ship.
The Associated Press reported
  that the 45-year-old aerospace engineer
  entered the water off
  Huntington Beach on a foggy
  Sunday morning, but he had problems
  equalizing and fell behind.
  He tried following his buddy's bubbles
  but lost them and decided to
  end the dive after 15 minutes. By
  that time he was already 400 feet
  down current from an oil platform
  where the boat was anchored. He
  blew his whistle, but the foghorn
  on the oil rig drowned it out. He
  inflated a safety sausage, but the
  fog was too heavy for it to be
  noticed. "I figured when the dive
  was over they would realize I was
  missing and come looking for
  me," Carlock said. But no one did.  
Assuming he'd be picked up
  when the other divers surfaced,
  Carlock told the San Diego Union-
  Tribune, "I was watching my watch,
  trying to ball park when people
  would be running out of air. At 60
  minutes you go, 'There's no one
  diving -- they're all in the process
  of getting onboard.' I told myself
this isn't undue cause for alarm.Maybe there are other people in
trouble beyond me."  
What he didn't know at the
  time was that no one onboard realized
  he was missing. As a divemaster
  from Ocean Adventures Dive
  Company (the Venice-based shop
  that organized the excursion) ran
  through a verbal roster check, an
  air compressor went down, distracting
  the divers and crew.
  Carlock's name was missed.
  According to Steve Ladd, owner of
  OADC, "Dan's dive buddy did not
  report that they had become separated
  and that Dan had not
  returned." After the interrupted
  roll call, the three divemasters
  from the shop did not perform a
visual verification.

 back-up systems are in place."

Faced with murky water and a
  strong current, and not realizing
  anything was wrong, the rest of the
  group decided to move about nine
  miles north to explore a shipwreck.  
Carlock took photographs of
  himself to document that he had
  made it to the surface. An hour
  and a half later he dropped his weight belt and periodically noted
the time on a slate."It was like the
  movie 'Castaway,'" Carlock said
  later. "There was a need to mark my
  existence." After about two hours in
  the water, Carlock started to shiver.
  But eventually the sun supplied
  some heat. "That's why I feared that
  if I wasn't picked up by nightfall it
  would be bad news," he said.
It was only following the second
  dive of the day that Carlock's
  absence was discovered, but the
  crew assumed incorrectly that he
  had disappeared at the second site.
  Sun Diver Captain Ray Arntz alerted
  the Coast Guard around noon,
  about two hours after leaving the
  original location, and a team of
  divers went down to survey the wreck. The divemaster slate had
logged Carlock out of the water at
the last site and back in the water
at the next site! And he wasn't
even on the boat.
While the Coast Guard, recreational
  diving instructors, Long
  Beach lifeguards, and L.A. Fire
  Department personnel searched for the missing diver in the wrong
part of the ocean, Carlock continued
to drift. Later, he told his harrowing
tale on Good Morning
America. "I thought about all the
things that I've left unfinished in
my life, and all the people that
would have to make up for my
mess. And, you know, all the living
that I haven't lived yet," he
recalled. (It seems that lost divers,
like shark attack victims, are now
entitled to 15 minutes of fame.)
After five hours, Boy Scout
  crew trainee Zack Mayberry, 15,
  aboard the tall ship Argus, spotted
  Carlock's head sticking out of the
  water about 150 yards away.
  Mayberry handed his binoculars to
  a friend. "I wanted to make sure
  my eyes weren't playing tricks on
  me," Mayberry said. Eventually
  Carlock, himself an ex-Boy Scout,
  was plucked from the sea. He was given warm clothes and hot liquids,
and eventually taken back to
the Sun Diver by the Coast Guard.
Lieutenant Commander John
  Fassero, Chief of Coast Guard's
  Investigations Dept. in the Los
  Angeles area, is investigating the
  incident. He told Undercurrent
  that Captain Arntz has been
  charged with negligence, and the
  Coast Guard is negotiating a settlement
  with him that may mitigate
  the terms of his suspension.Fassero notes that Arntz has an
  "outstanding record in the dive
  community," and has volunteered
  to contact other dive boat skippers
  to compare notes on roll calls and
  other procedures. "The captain is
  ultimately responsible for the passengers"
  under Coast Guard regulations,
  Fassero points out. And
  although the CG investigation
  shows that culpability in this incident is "widespread among the
  divemasters and the diver himself,
  with weather a contributing factor,
  Arntz was charged a because he
  holds Coast Guard credentials.
  Someone has to have accountability,"
  says Fassero. He added that
  PADI is reviewing the divemaster's
  conduct. 
Fassero is also meeting with
  PADI officials and several dive boat
  captains to discuss methods of
  improving onboard roll calls.
  Southern California's dive boat
  fleet is not organized, and there
  are no standard procedures. 
Eric Bowman, owner and
  operator of the popular liveaboard
  Peace, out of Ventura,
  points out that some boats charter
  strictly through dive shops and
  require the shops to provide divemasters.
  That means that different divemasters work each trip.
Others, such as Bowman, employ
their own crew, following their
own procedures.
Glen Fritzler, captain of the
  Santa Barbara-based Truth, told
  Undercurrent that his fleet "stopped
  using the oral roll call system back
  in the early '70s because it simply
  does not work." Instead, he maintains,
  "We use a plastic board and ask each diver his name. If we are
missing someone we continue our
search onboard until we find him
or her or start a full-blown search
(U/W recall, diver search, etc.). We
also perform a tank count in conjunction
with the roll call so you
can tell if someone is in the water."
Sounds good, but in 1995 I
  was on a lobster dive when the
  Truth left a diver behind, and no one missed him until another boat
pulled up with our missing shipmate
aboard. This highly competitive
lone wolf had been the first in
and last out on virtually every dive.
Not only didn't he have a buddy,
but he made no personal connections
with any of the other divers
aboard. So when he slipped
through the Truth's log-in system,
none of the passengers missed him
either. Later he told us that after
the Truth left him off San Nicholas
Island, he swam for three hours to
catch up with the other dive boat.
Not surprisingly, he kept hold of
his bag of bugs the entire time.
Fritzler also offered the dive
  industry's standard knee-jerk reaction
  to the Coast Guard's involvement
  in dive boat procedures. "We
  should remain a self-governing
  group and keep government out
  of our business," he told
  Undercurrent, adding that he was
  currently repairing another vessel,
  Vision, "after a government agency
struck the boat while at anchor!" 
LCDR Fassero points out that
  this is the first stranding he's
  encountered in four years of service
  in Southern California. He's
  not promulgating new regulations
  at this point. Rather, he's trying "to
  get the industry to recognize the
  need for improvement and their
  voluntary cooperation to look for
  solutions." He adds that diving is,
  after all, a recreational activity. "It's
  not supposed to be laborious."  
Fassero is aware of Divers Alert
  Network's Diver Identification
  System (DIDS), which DAN sells to
  boat operators. At the beginning
  of each dive trip, the divemaster
  assigns each diver an individually
  numbered DAN Tag, with the dive
  operation name and phone number.
  When the diver is on the boat,
  he or she places the DAN Tag on
  the DIDS board. Before diving, the
  diver removes the tag and clips it
  to his or her buoyancy compensator.
  The tag number will also correspond to the divemaster's roster
number. When returning to the
boat, the diver unclips the tag and
returns it to the board. Fassero
believes that this system has had
limited acceptance among dive
boat operators because the tags
can be lost. To him, "The conscientiousness
of divemasters visually
identifying the divers is the most
important factor."
Ironically, Carlock was diving
  with a shop and on a boat he's
  used many times, yet still he was
  overlooked. "There's definitely
  some anger on my part," Carlock
  said, adding that he did not plan
  to seek legal action. "They're kind
  of like family, and I don't want to
  destroy that." Ocean Adventures
  has suspended two staffers from
  divemaster responsibilities. "We are closely examining our existing procedures,
the guidelines recommended
by PADI, and those utilized
by other dive shops," says
Steve Ladd, adding that he has
stressed the need for visual as well
as audio check-ins during roll call.
As for the "buddy" who didn't
  stick with Carlock (he was assigned
  to him just before the dive) and
  who didn't report their separation,
  Carlock came face-to-face with the
  man (who happens to be a scuba
  instructor) when the Coast Guard
  eventually returned him to the Sun
  Diver. "Some people asked me if I
  tore into him," Carlock said. "It was
  too surreal -- I was more avoiding
  him. The anger comes out later."  
Carlock maintains his experience
  wouldn't stop him from  diving.
"To me, adventure and pressing
forth is a natural part of who I
am and who we are as a species --
to shrink back is not an option,"
Carlock said. "But I'm not foolish.
Before I dive again I want to make
sure changes are made and backup
systems are in place."
Although Fassero has been
  criticized by some divers for suspending
  the well-regarded captain,
  he says his aim is to send a
  message to all dive boat skippers.
  "The captain must be expected to
  be situationally aware of environmental
  risk conditions which call
  for greater due diligence, he told
  Undercurrent, and recommends
  that every skipper set standards
  (hopefully universal ones) for
  divemasters to follow when conducting
  roll calls.
