Mystery Surrounds Deaths of Coast Guard Divers

SEATTLE (Sept. 24) - Five hundred miles north of Alaska, a group of
shipmates from the Coast Guard cutter Healy tossed a football on the
blue-and-white, diamond-hard Arctic ice.

Others snapped panoramic photos and took walks during the two-hour break,
stretching their legs after a month aboard the 420-foot icebreaker.

Lt. Jessica Hill and Boatswain's Mate Steven Duque seized the chance for a
training dive and slipped into a patch of open water near the Healy's bow. A
team held ropes attached to the divers, lest they become disoriented under
the ice. Several research scientists watched from the deck.

But no one knows what happened on the other end of those ropes on that cold,
brilliant summer day - except that both divers died.

The Coast Guard has started two investigations, relieved the Healy's
captain, pulled all diving equipment off the ship and suspended all polar
diving. But nothing has been said about what might have killed Hill, 31, and
Duque, 22, on Aug. 17, or when the investigations will conclude.

"We can get no word whatsoever, and that's tough," Hill's father, William
Hill Jr., said. "We can't even get the death certificates."



The Healy was on a research mission backed by the National Science
Foundation. On board were three dozen scientists collecting data that would
help them map the ocean floor and study the Earth's crust to better
understand earthquakes, tsunamis and plate tectonics.

Hill, the ship's marine science officer and a native of St. Augustine, Fla.,
was an experienced civilian diver before she joined the Coast Guard about
four years ago. Her shipmates described her as a fun-loving officer who,
during a trip to the North Pole last year, posed on the ice in a bikini by a
red and white striped pole.



Duque, whose responsibilities included keeping the Healy's decks in order,
operating machinery and driving launch boats, was from Miami. Colleagues
said he was exceedingly professional and inspired others to take their jobs
seriously.

Both attended the Navy's dive school, which is required of all Coast Guard
divers.

The pair had been underwater for about 10 minutes, estimated Harm Van
Avendonk, a University of Texas geophysics researcher, and something
appeared to be wrong.

"I saw people from the bow looking intently down on the ice, and I sensed
immediately that they didn't look relaxed," he said. "It was taking a long
time for the divers to reappear."

In a blur, the crew's training took over, several witnesses said.

The divers were pulled up by the ropes. Blankets and stretchers were rushed
onto the ice, and EMTs immediately began performing CPR.



The divers were carried to the ship's sick bay, where they were pronounced
dead roughly two hours after the dive.

"What I can tell you is this: These people were very well trained. Every
time we did something we had to have a safety briefing," said Steve
Stevenoski, a high school teacher from Wisconsin Rapids, Wis., who was
videotaping the frozen seascape when he heard shouts from the dive support
team.

"There was an accident that was completely unforeseen," he said.

According to Coast Guard protocol, they would have created a "dive profile,"
detailing who was diving, how far down they were going and how long they
would spend at various depths.

Typically such plans are drawn up by a ship's dive officer, though the
captain is ultimately responsible for the safety of divers. That could
explain why Capt. Douglas Russell was relieved of command less than two
weeks later. Vice Adm. Charles D. Wurster, commander of the Coast Guard in
the Pacific, said he had lost confidence in Russell.

The only signs of the tragedy during a recent tour of the ship were a grief
counseling pamphlet on a table in the scientists' lounge and the locked and
empty room where dive equipment was stored. The equipment was shipped to the
Navy's dive school in Panama City, Fla., for examination.



One Coast Guard investigation is focusing on the root cause in hopes of
preventing future accidents; the other is a broader administrative
investigation that could result in findings of responsibility.

One investigator, a lieutenant, said Hill and Duque were the first Coast
Guard divers to die under water since the 1970s.

The Coast Guard described the dive as routine, but any dive in frigid waters
beneath 4-feet-thick ice poses serious dangers. The cold can numb the
extremities. Divers typically wear dry suits, which use air to help
determine buoyancy. Such suits can balloon during ascents as pressure
decreases - if the diver doesn't release the air quickly enough, he or she
can shoot toward the surface and crash into the ice.

They also must use equipment that can handle the cold, such as breathing
regulators outfitted with rubberized covers filled with antifreeze.

The deaths were hard on the Healy's crew of 75, said Ensign Stephen Elliott,
who was on the ice as part of the dive support team that day.

"These are people you watch movies with, eat with, joke around with," he
said. "It's hard to explain to someone who doesn't live on a ship what it's
like to be a shipmate. They were incredible shipmates."

Is this true? I've never heard of such a thing. I don't think my reg
has antifreeze in it and it's supposed to be good for even the coldest
dives.

I know some Dacor regs, circa 97-98, do it for a fact.

It was a modification, and, the kit came with a tube of liquid and a
rubber plug.

It's true. Some regs use a cap and pack the exposed part with
Christolube or some other such grease. Apeks has regs that are dry
sealed so no water gets in. Sherwood regs use a bleed system that helps
keep them from freezing. What reg are you using?

I found this comparison from last year which lists a bunch that are
designed for cold water diving.

Yes.

What a surprise.

Filling the first stage with "Antifreeze" (silicone grease, actually)
isn't the only way to prevent one from freezing.

True, Poseiden recommends vodka as the antifreeze.

Well, it still an "antifreeze" <g>

I'd suggest a design of experiments to evaluate the effectiveness of
various distiller's' products, as long as someone could figure out a
way to preserve the quality of the product for further uses.

It is said the Swedish have a quick disconnect design for
the antifreeze cap. Reason why they don't care about further
use, they simply replace the stuff.

The replaced stuff is said to continue it's purpose as an
antifreeze, though.
