Your ID shows as in Dallas. Was that Windy Point, Lake Travis? Several people have stated that you should have called the dive at that point. Guess they didn't notice how you went from fine/normal to zip instantly. Good catch on being able to find everybody in conditions where I'd have a hard time finding a turned on flashlight.

I won't spend too much time on my story since that not what the thread is about. The AI was always with the other two students. When I found the three divers I checked their gauges and saw the ERR, we aborted the dive and did a normal ascent. Yes, it was Windy Point.

My point was that conditions can be very variable and there can be great difficulty in maintaining direct contact in such conditions, especially with multiple students. Plus, students don't always follow briefing instructions on separation procedures.

The Yukon is one of the best dives you can do in San Diego - that being said, there are times when conditions are just not appropriate for diving it. In fact there have been more times than I can count that my dives have been cancelled due to poor conditions and rough seas. On the boat, I have had 60 feet of viz and other times 3 feet. I took an advanced class down one time and they didn't know they were on the boat until their fins hit the steel. IMHO, the Yukon is not a beginner dive, and I usually dive it with doubles or a steel 120 - plenty of air for the unexpected. If I teach a wreck class, I keep the ratios to two students per instructor due to the variability of conditions.

I am sad to know a diver lost their life - my heart goes out to the family. I expect soon we will have answers to learn from this accident and all become a safer diving community.
 
It's sad to hear of yet another diver fatality. I have dived on two of the HCMS Yukon's sister ships in B.C. and am familiar with their general layout though I can't comment on the conditions at the site of the Yukon having never had the pleasure of diving there. That being said, Mackenzie class vessels that have been properly prepared for artificial reef deployment can be very enjoyable wreck dives if done properly with the required training and just as enjoyable for non-penetration dives as well.

It will be very interesting to see what the official report says when it comes out.

My heartfelt condolences go out to the friends and family of this unfortunate young lady. May she rest in peace and her family find the solace and answers they no doubt are seeking.
 
I've been lurking in this thread, and only just finished reading the entirety.

We know for a fact she had a BC malfunction. I'm sure this somehow played a role in the accident.

We are fairly sure she had buddy separation at some point. She was discovered per the official statement by her instructor and classmates who attempted to cut her loose from ropes she was tangled in.

I dove the Yukon once for my AOW both deep dive and wreck dive. I was lucky, viz that day was in excess of 30 feet. Highly unusual and I had a very good view of the ship up and down. I remember the dive itself was cold. I even layered a 3 mm vest under my 7 mm wetsuit and felt chilled towards the end of the dive.

I also have been on Waterhorse Charters and the Humbolt. They were great and despite the tragedy I personally would love to dive them again. The one thing about the Humbolt is they have LP 85 steel tanks. Part of the dive briefing is to be aware you should be dropping some weight if you normally dive the AL 80's.

As for the accident, does anyone know or was it mentioned that the victim had a knife or cutting tool on her? For my wreck instructions it was recommened that a knife or cutting tool should be mandatory equipment because of the risk of entanglement. It should also be placed in an area the diver can access easily with either hand. It's fine to think you're okay with a buddy who has a tool but what happens if you are separated in this case?

It might be as simple (speculation) that she was overweighted with a steel tank, compounded problems with the BC malfunction, became entangled as a consequence when separated, and then was unable to extricate herself due to lack of a cutting tool.

As with many tragedies it is usually not one really big problems that makes things go downhill. It is usually a bunch of little things, each one in and of themselves not a big deal until they snowball past the point of no return.

Sorry, but it has been brought to my attention that the diver's equipment has not been fully tested so it may be premature to state she had a BC malfunction. I had based my assumption that ABC report stating lifeguard statements she had difficulties with her buoyancy apparatus was the same.

To restate, it was reported that she had difficulties with her buoyancy apparatus and likely contributed to the accident.

I don't believe a broken BC alone would prevent a diver to surface. I hypothesise that the BC malfunctioned during a struggle after entanglement due to poor viz resulting in the first rescue by the buddy failed and popped to the surface. (because the troubled diver was anchored to the wreck)

Also at those depths it is possible that Nitrogen Narcosis could have played a role , a diver under stress and fatigued could experience the effects at shallower depths making getting untangled harder,

no knife risks life
 
I agree that you cannot always predict the conditions you'll encounter ... and in a similar situation I immediately terminate the dive. You can't evaluate what you can't see, after all.

Bob, I agree.

These have been my thoughts reading this thread. What time of the day did this dive begin? Did the captain or instructor seek information on conditions using the VHF radio? By 9:00am on any morning off the coast of Florida, UW conditions are chatted about endlessly on the radio. If not, pickup the microphone and ask. Got a load of non-expert student divers on board? Option 2, drop a DM in the water for a first-hand account of conditions. It has been reported that visibility was as low as 5ft.

We're not Florida divers. 5 ft. vis isn't a great day, but it's divable. It's not necessarily a cancel the charter condition.

There was an instructor and a DM in the water. If it weren't divable for their advanced class, they could have called the dive.

Similarly, none of the other conditions described would have led to canceling the trip.

We routinely dive in such conditions.

Here is an article from the San Diego Union Tribune, 12-08-12

MISSION BEACH — Anastasia Jackson was not your typical girlie girl. When the 26-year-old Philadelphia native wasn’t on duty as a Camp Pendleton Marine, the lance corporal spent her free time rappelling, bow hunting, shooting, playing video games and reading Tom Clancy novels. To her friends and family, she was a woman who could do it all.
“She was the real G.I. Jane,” said her older brother, Elliot Jackson of Philadelphia.
That’s why her death last weekend during a scuba dive off Mission Beach has left her military colleagues and loved ones so baffled.
Anastasia Jackson was diving on the Yukon, a sunken Canadian destroyer escort, with a dive instructor and three other classmates when she began having problems with her buoyancy, said San Diego lifeguard Lt. Nick Lerma.
The divemaster tried to keep her from descending all the way to the bottom by inflating his own buoyancy compensator. But the two lost their grip on each other. She dropped deeper, and he rocketed to the surface, Lerma said.
Her body was located about two hours later, just inside one of the ship’s compartments, lifeguard officials said. Her instructor and a classmate found her tangled in ropes.
By all indications, Jackson accidentally drowned on Dec. 1, said San Diego police Capt. Brian Ahern, although an investigation has been launched to determine what exactly went wrong.
The poor conditions that day didn’t help the situation. The coast was under a high-surf warning, and visibility was about five feet.
“The surge was nothing less than violent,” Lerma said.
The rough water knocked around searchers that afternoon and delayed the recovery of her body until the following morning.
The Coast Guard and the Medical Examiner’s Office are collaborating with police on the investigation. Jackson’s dive equipment is being examined at the Scripps Institution of Oceanography for possible malfunctions.
At least three other divers have died at the Yukon site since 2000, when the ship was scuttled to create an artificial reef for recreational divers. The 366-foot warship lies nearly 2 miles off Mission Beach, in 105 feet of water in an area known as Wreck Alley. Many divers just explore the exterior of the wreck, but more advanced divers choose to enter its many compartments.
A German woman died in 2001, last seen alive descending to the Yukon.
Four years later, an advanced diver drowned after he entered an off-limits boiler room, where he likely suffered blackout conditions due to kicked-up silt, got disoriented and ran out of air.
Another dove the site without a partner.
The site has also had its share of rapid ascension-type injuries, when divers misjudge the amount of air left and aren’t able to take safety stops before surfacing, said lifeguard Lt. John Everheart.
“It is a deep dive. It’s certainly not a beginner’s dive,” Everheart said.
Jackson’s family said last week that they are reserving all comment on the accident until the investigation is complete.
Her commercial diver father, Bruce Atkins, remembers how Jackson would observe and assist him on dive outings in Miami as a little girl.
She had only recently started getting her dive certifications, working up to her advanced open water certification. She was working on her wreck diving specialty when she died.
She had plans to possibly take over her father’s business, Lux Sea Commercial Diving, Atkins said.
Jackson joined the Marines in 2010 and was a special intelligence system communicator assigned to the 1st Radio Battalion, 1st Marine Headquarters Group, I Marine Expeditionary Force.
“She was always a tremendous ball of energy, always a daddy’s girl,” said her father. “She excelled at everything she did.”
“She has hundreds of friends in disbelief.”

When I went to Monterey for my son's graduation from the Presidio I took my drysuit and other gear. The dives themselves were good dives. But I took note at the difference between diving the Pacific in that area and the Keys for example. The day we went out was in seas that I saw Keys ops canceling dives. As I recall the seas were running 4-6 with a 9 footer tossed in here and there on the way to and from the sites. We dived in a couple protected bays but the ride to them was a trip.
 
Someone made a good point earlier about the conditions... Topside, you can have glassy surface and calm weather but underwater you could descend into a washing machine. I got a couple of snide replies on another forum when I mentioned that conditions weren't favorable for diving~ 2 people responded with how nice the conditions on the surface were. Since when does the surface dictate how diving conditions below will be? You just don't know if you're dropping into 2" or 50 feet of visibility, no surge or rock slamming underwater gusts. You could drop down into lake-like surface conditions and surface in 6 ft rollers.

We had stormy conditions that weekend and I was surprised people were diving- even if the wind & waves had settled, conditions underwater usually won't be ideal for a couple of days after the storm. Nevertheless, the boat went out... (I don't fault the boat charter~ they are seasoned professionals and completely capable of handling any emergency).
I do, however, fault the instructor. You DO NOT surface before your students, period. If you have a runaway ascent diver, you can only let them go once they are out of reach... You don't chase after them and risk getting yourself bent as well~ you try to grab a leg, a fin, whatever you can (although you should be preventing this issue in the first place) and try to stop them. You send the AI or DM (assuming you have one) up to tend to the runaway diver, and you gather up your remaining students and do your controlled ascent together. So I have a difficult time not questioning the judgement of the instructor although I'm trying to save my judgement until all of the facts are released.

With that said, I got this in email today for anyone interested:
There will be a memorial service for Anastasia Jackson at the Paige Field House, Camp Pendleton on Wednesday at 0900. You are welcome and invited to attend.
